Dr. Mario World is a discontinued puzzle game in the Dr. Mario series for iOS, iPadOS, and Android devices. The game was originally set to release on July 10, 2019, but ended up being released a day earlier on July 9. It was a free-to-download game with in-app purchases that was co-developed by Nintendo, LINE, and NHN Entertainment, and it was available initially in 59 countries/regions, including Japan and the United States. The game supported multiple languages, including Japanese and English. Dr. Mario World is the second game of the Super Mario franchise for mobile devices, following Super Mario Run, though it is the first free-to-play mobile game featuring microtransactions and gacha mechanics in the Super Mario franchise. Pre-registration for the game opened on July 1. Like Super Mario Run, the game required a constant internet connection to play.

Dr. Mario World takes advantage of the touchscreen controls of the smartphone, where players dragged capsules with the touchscreen to eliminate viruses, though the core gameplay is slightly tweaked in comparison to prior Dr. Mario titles in that players solved puzzles with a limited number of capsules rather than infinite capsules against a time limit. New gameplay elements include three introduced colors of viruses: green, light-blue, and pink viruses, which occur mixed in the regular red, blue, and yellow viruses later in the game. Dr. Mario World features the debut of playable Super Mario characters as doctors than prior Dr. Mario games. These doctors have special abilities that help clear levels more easily. In addition, doctors can be paired with a wide variety of assistants, which constitute primarily of generic Super Mario enemies. As well as having a single-player mode, Dr. Mario World introduces a competitive versus mode, where players battled against opponents online in a gameplay style similar to that of the traditional Dr. Mario games.

The game ended its two-year services on November 1, 2021, at 6:00 a.m. (UTC). A day later, the "Dr. Mario World Memories" website was released, allowing players with Nintendo Accounts to view personal statistics and collected medals from the game.

Story

The opening cutscene of the game

A virus outbreak has occurred in the Mushroom Kingdom, infecting Koopa Troopas, Toads, and Shy Guys, and Dr. Mario begins hunting down viruses to save the locals. Dr. Toad instructs Dr. Mario on how to eliminate viruses in the first demo level, featuring only red viruses. By the third (eleventh in version 1.10) level, Princess Peach notices that the Toads need her help while Bowser wants to take care of the viruses affecting his minions himself, so they join Dr. Mario as playable characters.

Gameplay

As with previous Dr. Mario games, the main and most common objective is to eliminate all of the viruses on the screen by connecting capsules of the same color to each of them, although instead of the capsules descending, the game's gravity is directed upwards with the viruses positioned towards the top of the screen. The player first drags a capsule from the bottom of the screen onto the field to use it, and the player can drag it again to move it or increase its "falling" speed, or tap it to rotate it horizontally or vertically; if there is an open space for the capsule to fit through, the player can drag the capsule towards that open space as well. Viruses are eliminated if three (as opposed to four) or more of the same color are matched. If the player uses a half of a capsule to eliminate viruses, the other half remains, and the player can drag it around as an ordinary capsule if it is free to go up the screen. Players earn a rainbow capsule if they make seven matches that eliminate viruses; these rainbow capsules can be used in tandem with pills of any color to eliminate viruses, though they take up only one tile on the screen. The classic red, blue, and yellow viruses return, while new green, purple, light-blue, and pink viruses make their debut, though purple viruses have never appeared in any stage before.

Depending on the stage, various obstacles may appear on the field, including Empty Blocks and Brick Blocks, and viruses can be hidden inside the Brick Blocks. Helpful objects such as shells, exploders, and skill chargers can also appear among the viruses. When matched with capsules of the same color, the helpful objects help out the player: Shells clear out viruses within the same row, exploders eliminate surrounding viruses, and skill chargers significantly fill the doctor's skill meter. There are various objects that act as obstacles, such as ice that may trap viruses that require a match to remove the ice, bubbles that shield them from capsules once before they disappear, and cages that require clearing the lock block to release them.

Special items can be used prior to entering a stage and while in the middle of a stage, aiding players to clear the stage. Dr. Toad gives out free items for a trial use, but after the single use, players need to purchase the items with diamonds or coins.

Game modes

Dr. Mario World has three main modes (stage mode, versus mode, and Skill Summit), a daily booster (daily mode prior to its introduction), and events. Stage mode serves as the game's single-player mode, while versus mode serves as the game's multiplayer mode. Versus mode is unlocked when players have cleared Stage 5 (20 in old versions). Skill Summit is unlocked when players have cleared Stage 20.

Stage mode

The stage overview where the stage's information is shown

Stage mode is the mode players first start through and requires players to fulfill various objectives in order to clear stages. The most common objective is to eliminate viruses, though other objectives include obtaining Virus Coins hidden in Brick Blocks. Stages are grouped into worlds, beginning with five—which are, in order, grass-, desert-, beach-, ghost-, and sky-themed—with more to be added in the future. Each world has two areas, which have 20 stages in each area. Each world also has its own set of challenge stages, in which players need to clear the stage before the time limit runs out, except for the last world where the challenge stages are not timed. Unlike in the prior Dr. Mario games, players are limited to a certain number of capsules per stage.

In order to play a stage, the player needs to have at least one heart. A heart is regained automatically every 30 minutes, although players can purchase hearts with diamonds or clear a stage for a free heart (prior to version 2.3.0, clearing only uncleared stages rewards a heart). Since version 2.4.0, players who made at least one in-app purchase prior to that version have unlimited hearts. In the first 20 stages, players have an infinite number of hearts; afterwards, players are granted a max number of 10 hearts (five hearts prior to version 2.3.0), where if they have less than that number, each heart takes 30 minutes to refill. Diamonds can also be used to obtain items, obtain new doctors and assistants, and continue a stage should a player fail to clear the objective after running out of capsules or time (although only two continues are allowed per attempt). Diamonds can be purchased through the app with real money. Two versions of continues are available: One of them provides five capsules or 15 seconds of time for the cost of 10 diamonds, while the other provides eight capsules or 30 seconds of time for 15 diamonds.

When a player clears a stage, they earn coins, a heart, and a number of stars depending on how many capsules are left when they have cleared; they can earn a max number of three stars for the best score. Coins are rewarded only if the player has not obtained the star(s) yet, while hearts were not rewarded for cleared stages prior to version 2.3.0. If a player retries or fails a stage too many times, Dr. Toad provides the player with extra capsules or time to the player (previously he uses a free hammer on a tile for the player), giving three extra capsules or nine extra seconds in the process. This amount increases in number the more they failed to complete that stage. Since version 2.0.0, diamond offers for three items for the price of two appear (boomerangs, skill fillers, and Capsule+ in this order based on the number of times failed).

Versus mode

Dr. Peach facing off against Dr. Bowser in the game's versus mode

In versus mode, players pit against other human opponents online or against their friends, and it plays similarly to the multiplayer modes of previous Dr. Mario titles. The goal for players is to clear viruses in their grid to send viruses to their opponent's side; players lose if an object crossed the bottom line of the stage. When players clear viruses, their attack meter fills; when the attack meter is full, players can send row(s) of viruses to their opponent. The attack meter influences the amount of viruses/objects that must be cleared before they attack. Every doctor sends a different amount of lines of viruses for each attack, determined by a bomb with a number: for example, Dr. Mario sends 2 lines of viruses on each attack while Dr. Toad sends 1 line of viruses on each attack. Players can view their opponent's grid as well as a dotted line indicator showing how far viruses are down on their opponent's stage. Additionally, players have a chance to prevent opponents from sending viruses to them; the higher their doctor's defense stat is against a specific bomb, the likelier the attack will be defended against.

If the player successfully eliminated all the viruses on their field, they will send three lines of viruses to the opponent that cannot be defended against while at the same time resetting their opponent's attack meter. They also gain three more lines of viruses after they attack, so that the player has viruses to work with. However, if there is an object that is close enough to the bottom after all viruses are cleared, the object will go past the line and the player will lose. When both players have not yet reached a point where one of them has filled the board, there will be a warning. After a brief period of time, the field will be pushed down by one line of blocks that cannot be cleared, and will continue to do so at 10 second intervals until there are only two rows to work with. If a player is left with three or less rows left, clearing all the viruses will not result in extra lines of viruses forming.

Players are sorted into tiers, which serves as the game's matchmaking feature. As of now, there are 11 tiers: Tier 1 to 10, and a Rainbow tier. Each tier has different virus layouts, and in a few of the tiers, the virus colors are different from the standard red, blue and yellow viruses. Some objects are only present in higher tiers, such as barrels in Tier 10. In the Rainbow tier, non-virus objects appear when new lines appear on each player's field even if the appropriate assistant is not equipped, whether it is an attack from the opponent or as a bonus for eliminating all viruses. Players earn battle points if they win matches and lose battle points if they do not. The amount of points earned compared to the amount of points will be a net positive for lower tiers (tier 9 and below currently), but in higher tiers (tier 10 and Rainbow tier) the amount of points gained for the winner is the same as the amount of points lost for the loser. If players of different tiers are matched up, the winner in a lower tier will earn more points than usual while the loser loses less points than usual, but if the winner is in the higher tier they will earn less points than usual while the loser lose more points than usual.

When enough battle points are earned, players ascend tiers and the higher their tier is, the better rewards they earn for winning. The following amount of battle points are required to reach the respective tiers since their introductions: 400+ (tier 2), 800+ (tier 3), 1200+ (tier 4), 1600+ (tier 5), 2100+ (tier 6), 2600+ (tier 7), 3100+ (tier 8), 3600+ (tier 9), 4100+ (tier 10), 5000+ (Rainbow tier). The first time a player reaches a tier, they gain rewards based on where they are promoted to. The rewards are: 1000 coins for tier 2, 3000 coins for tier 3, 1 staff ticket each for tier 4 to tier 7, 100 doc tokens each for tier 8 to tier 10, and 200 doc tokens for Rainbow tier. Prior to version 2.4.0, a 72-hour offer appears in the shop, where the diamonds and potentially other items offered are proportionally higher than anything else in the shop.

Starting from version 1.4.0, which is also when season 3 started, the specialists feature is introduced. During each period, which typically lasts for 7 days, four or five doctors are selected to be specialists, in which they gain a couple of advantages in each match. For more information on specialists, refer to: List of specialists in Dr. Mario World.

Players earn coins and/or keys for a battle box if they win battles. Coins are earned if the player has won 20 or less times in a day, and are rewarded with more coins the higher their tier is. Likewise, keys are earned if the battle box has not accrued enough keys yet, where it was 7 keys prior to version 2.1.0 and 5 keys since then, although at certain time periods the amount of keys required is reduced to 3. If they have enough keys, they can open battle boxes to obtain random loot in them such as coins, hearts, staff tickets, items, etc., including special assistants exclusive to higher tier battle boxes. In older versions, some of the battle boxes may contain viruses, where the player essentially won nothing from it. Battle boxes can be opened once every 10 hours after they have been opened, but by using up to 3 diamonds (depending on the amount of time left), players can immediately obtain a new box to unlock. Diamonds can be spent this way for up to five times a day.

Once every two to three months, the game is updated to add a new season, which adds new tiers. When a new season starts, players earn 20 coins for every point they have over a specific threshold in addition to doc tokens for some seasons, before the score is reduced to that threshold. Tiers are held during the following periods (start times are all 6:00 UTC and end times are all 5:59 UTC):

Season	Start Date	End Date	Notes
Season 1	2019-11-14	2020-02-06	Tier 6 is introduced, requiring 2100+ points to reach Tier 7 is introduced, requiring 2600+ points to reach At the beginning of the season, battle points higher than 2000 are reset to that amount, earning 20 coins for every point deducted.

Coin rewards from winning matches are reduced to 60% of the previous reward (e.g.: tier 1 winners will win 12 coins instead of 20 coins)
Season 5	2020-12-10	2021-03-18	Rainbow tier is introduced, requiring 5000+ points to reach In Rainbow tier, exploders appear at the start of the match and as attacks in addition to viruses At the beginning of the season, battle points higher than 4500 are reset to that amount, earning 20 coins for every point deducted. 100 doc tokens are also awarded for exceeding that amount of battle points.
Season 6	2021-03-18	2021-06-03	Rainbow tier is refreshed, with a different colored background In Rainbow tier, skill chargers appear at the start of the match and as attacks in addition to viruses At the beginning of the season, battle points higher than 4999 are reset to that amount, earning 20 coins for every point deducted. 200 doc tokens are also awarded for exceeding that amount of battle points. Starting from version 2.3.0, skill chargers are not guaranteed to appear among viruses in Rainbow tier
Season 7	2021-06-03	2021-08-26	In addition to Rainbow tier, tiers 4 to 10 will also have skill chargers occasionally appearing as attacks in addition to viruses (starting layouts do not have skill chargers for non-Rainbow tiers) At the beginning of the season, battle points higher than 4999 are reset to that amount, earning 20 coins for every point deducted. 200 doc tokens are also awarded for exceeding that amount of battle points. Opening stage layouts are changed up
Final Season	2021-08-26	2021-11-01	At the beginning of the season, battle points higher than 4999 are reset to that amount, earning 20 coins for every point deducted. 200 doc tokens are also awarded for exceeding that amount of battle points. Because the end of this season coincides with when this game's service ended, rewards based on the amount of points earned were not given out, unlike prior seasons.

Daily Booster

The Daily Booster, introduced in the version 1.3 update, replaces the Daily Gift. The player eliminates viruses to earn coins and doc tokens. Once all of them have been eliminated, everything on the stage is eliminated, and new viruses appear after a few seconds. When the player runs out of capsules and cannot make any more moves, an object reaches beyond the bottom-most row, or the player quits the daily booster from the menu, the game ends and the player cashes in their rewards based on the amount of viruses cleared. The player gets 4 coins for every virus eliminated, and one doc token for every 45 viruses eliminated. It can be played for free once per day, and can be played again using diamonds, with the rewards being received at a tripled rate: each virus rewards 12 coins and each doc token is rewarded for every 15 viruses eliminated. Once a triple-reward game is finished, the player must wait until the next day to play this mode again.

Prior to version 1.3.5, a single music theme plays during both the Daily Booster rounds and the results screen. After that update, the theme that plays during the round has changed, with its old theme only played at the results screen.

Starting from version 1.4.0, the Daily Booster received a few changes. The following changes are made:

• Players start with 20 capsules instead of 30 or 33 capsules.
• Each round starts with more viruses and objects on the field compared to the previous updates.
• After all the viruses are eliminated in a round, two capsules are rewarded instead of five.
• Only two colors of viruses and objects are available. Since the change, only red and blue are available but as of version 2.1.0, any two colors between red, blue and yellow are randomly selected.
• The objective shown at the start of the first round will display infinite viruses instead of the number of viruses in the first round.

Skill Summit

See also: List of Skill Summits in Dr. Mario World

The Skill Summit, introduced in the version 2.0.0 update, is placed next to Stage mode or Versus mode. This mode is only available after the player has finished Stage 20 in Stage Mode. In this mode, four different doctors are assigned as mentor doctors, and each stage will feature one of those doctors. Each stage in this game is called a summit, and there are four types of summits: Basic, Intermediate, Advanced and Special. For the first three types, players can choose a doctor of their own, but in the Special summits, players must have at least one of the two eligible mentor doctors before they can play that summit. In regards to the player's choice of doctor, players cannot choose the same doctor as the mentor doctor. For example, if the mentor of the stage is Dr. Baby Mario, the player will not be allowed to use that doctor. Similarly, variations of that doctor are prohibited, so in Dr. Baby Mario's case, Dr. Mario, Dr. Fire Mario, or 8-bit Dr. Mario cannot be selected as the doctor. Besides the regular, baby and fire versions of specific characters, Dr. Bowser and Dr. Dry Bowser are considered the same type of character and thus cannot be used together.

Similar to stage mode, the player needs to have at least one heart before they can play a summit. In each summit, players are assigned various objectives and a limited amount of capsules to accomplish those objectives. Should a player run out of capsules before the objective(s) are completed, diamonds can be used to continue that summit for up to two times. Each summit plays similarly to a stage in stage mode, but the difference is that a mentor doctor is displayed at the top-left corner with a meter. This meter will fill each time a capsule is added to the stage, and once it is fully filled, the active capsule will be replaced by that mentor doctor's icon. The player must activate that mentor's skill before they can introduce more capsules to the stage, although other functions can still be used such as utilizing capsules currently on the stage, use in-stage items or activating their doctor's skill if it is filled. The mentor's skills may differ from their doctor's skill, typically with reduced effect. For example, while Dr. Baby Peach's skill normally change the next three capsules to rainbow capsules, Dr. Baby Peach's skill as a mentor instead only change one or two next capsules to rainbow capsules.

After clearing a summit, players will be awarded Kudos, which are functionally the same as clear stars in stage mode in that reaching specified benchmarks in the score will reward up to three of them. Each new kudos obtained will reward the player with 50 coins, for up to 150 coins. In addition to this, clearing a stage will reward a player with a heart (prior to version 2.3.0, only when the stage was originally uncleared), no matter the score. Rewards can be earned by reaching a specific number of kudos, which can include stage items, doc tokens, staff tickets, 10% score boost in Stage Mode or even a new doctor. Players are also rewarded if they cleared all stages in each type of summit, which can include extra capsules boost in Stage Mode, faster skill meter charge, Staff Tickets and 100 doc tokens. The Stage Mode boosts earned from Skill Summit are bonuses specifically for Stage Mode (thus, the changes do not apply to Daily Booster), and they last for 24 hours starting from the time each bonus is obtained, but it only takes effect in stages up to a specified World. The duration of the bonuses are cumulative, meaning that if the player has a bonus that is still active, obtaining another of that same type of bonus will extend the period for another 24 hours.

During the Skill Summit's first week and third week, there will be a staffing event where one or two of the doctors will have a higher chance of being added, allowing the player to potentially play the Special summits as they require specific doctors. The only exception thus far are Dr. Dry Bowser and Dr. King Boo, who are not obtainable by regular staffing. In addition, the shop will have two options for purchase each week for two of the Skill Summit's featured doctors: one is a purchasable Doctor Pack that contains that doctors alongside 210 (200 + 10 bonus) complimentary diamonds, while the other is a Referral that can be exchanged for 100 diamonds.

Each Skill Summit lasts for two weeks, although the duration was increased to four weeks from the 19th summit onward. After that, a new Skill Summit will replace the old summits and the rewards and kudos are refreshed. Starting from version 2.2.0 when the 10th Skill Summit begins, obtaining enough kudos will reward players with medals, and getting all of the kudos will reward the player with a Platinum/Dazzling medal that contains a number that signifies the rank of the player that collected it.

Events

Doctor's Orders

Doctor's Orders are a list of objectives that players can complete for bonus coins. The player is given 5 different objectives at one time. Some objectives can be filled in both stage mode (which extends to Daily Booster and Skill Summit) and versus mode while others are exclusive to neither. Once one of the objectives is completed, it takes 6 hours (20 hours prior to version 1.1.0) to receive another, while skipping an objective takes 1 hour (8 hours prior to version 1.1.0) before a new one is replaced. The following are doctor's orders that can appear since version 1.1.0:

See also: List of Clinic Events in Dr. Mario World

For this event, the player needs to do the following steps for the event:

1. Examine the patient.
2. Eliminate the viruses.
3. Clear all stages with three stars!

Once a step is cleared, the player earns rewards as well as a medal with the patient on it. The character depends on the current season:

• Season 1: Blue Toad
• Season 2: Goomba
• Season 3: Spike
• Season 4: Koopa Troopa
• Season 5: Piranha Plant
• Season 6: Green Toad
• Season 7: Paragoomba

• Season 10: Blooper
• Season 1 (revisit): Blue Toad
• Season 2 (revisit): Goomba
• Season 3 (revisit): Piranha Plant
• Season 4 (revisit): Blooper

Collect Clear Stars

In Collect Clear Stars!, the player needs to collect stars and receive rewards. However, they do not count if they were previously earned. These events are active when a new area of a world is added, meaning that new stages are added.

Most of the time that this event is held, the rewards gained are the following:

• 5+ stars: 500 coins
• 10+ stars: 20 doc tokens (1 Capsule+ before May 20th, 2021)
• 20+ stars: 3000 coins
• 30+ stars: 30 doc tokens (2 Capsule+ before May 20th, 2021)
• 40+ stars: 3 Score+ and 1 staff ticket

Eliminate the viruses!

In Eliminate the viruses!, also referred to as Virus Events, the player eliminates viruses in stages and receive rewards. They only count in stage mode. Before Skill Summit was introduced, these events are sporadic but after its introduction, they are active on any week where there is not a Star Clear event.

The rewards gained are the following:

• 300+ viruses: 500 coins
• 500+ viruses: 20 doc tokens (1 Capsule+ before May 13th, 2021)
• 1000+ viruses: 3000 coins
• 1500+ viruses: 30 doc tokens (2 Capsule+ before May 13th, 2021)
• 2000+ viruses: 2 Capsule+ (2 Hammers before May 13th, 2021) and 1 staff ticket

Power Boost Rally

Starting from version 2.2.0, Power Boost Rally is introduced, which can be activated after Stage 20 in Stage Mode is cleared when all the stage start items are unlocked. When Power Boost Rally is active, the player is able to use certain stage start items as a bonus without using up limited free items or diamonds. In order to activate Power Boost Rally, the player has to beat an uncleared stage without losing or restarting that stage. Once the requirement is met, they will be able to use Power Boost Rally that lasts for 48 hours since the first time the player clears an uncleared stage. Once the Power Boost Rally's 48 hours are expired, the player will not be able to start another Power Boost Rally until the next day on the mobile device's clock.

Depending on the amount of stages cleared in a row, the player gains the following boosts:

• 1+: Rainbow Start (Changes the first 3 capsules into rainbow capsules)
• 2+: Skill Up (Start the stage with a full skill meter)
• 3+: Capsule+ (Adds 5 capsules)

If the player loses or restarts an uncleared stage, the boosts are lost and the player needs to start over. However, the streak is not affected for stages the player has already cleared, challenge stages or special stages, so the player do not lose the boosts if they didn't manage to clear them on the first attempt. Prior to when World 26 was introduced, the boosts are also lost if the player has reached the stages in around the last two added worlds.

Characters

Doctors

Dr. Mario World features 45 playable characters. Each playable character offers a unique special skill that can be activated during gameplay. Players start with Dr. Mario when they first play the game and unlock Dr. Bowser and Dr. Peach when they have beaten stage 3; if players pick one of the three characters, the other two characters become unavailable. As of version 2.0.0, Dr. Toad is earned as another doctor when players have beaten Stage 20.

Players can purchase new doctors with coins, diamonds, staff tickets or doc tokens in the Staffing menu of the game (The exceptions are Dr. Dry Bowser and Dr. King Boo, who is as of now only available as occasional in-app purchases), although the doctors are obtained randomly and duplicates may occur. If players receive duplicate characters, it goes towards that doctor's skill level. Level 1 doctors require one copy, Level 2 doctors require two copies, Level 3 requires 5 copies, Level 4 requires 14 copies while the maximum level requires 30 copies. Players stop earning duplicates if a particular character has a maxed out skill level of that available doctor. Reaching new skill levels will make the skill meter fill faster for that doctor in stage mode, while in VS mode the skill meter will fill faster and/or increase the potency of the skill.

Doctor stats

The following are the stats for all doctors in Versus mode. The bomb displays how many rows of viruses the doctors can send to their opponents, the speed lists how many viruses or capsules are required to be eliminated for the meter to fill, and the defense represents the chance a doctor has to block against the bomb displayed. The rate skill meters are charged are hidden and differ from each doctor.

Assistants

Dr. Mario World features 64 assistants. Assistants, like the doctors, have unique skills that aid the player. Up to two assistants can be selected at once. Like doctors, these characters' skills level up by obtaining duplicates. Goomba is earned as the first assistant when players reach Stage 5.

In the description of the skills, the bolded portion of the assistant's effect is different depending on the level, which is the value for level 1 to 5 respectively.

Worlds

There are 31 worlds in total. Each world is sorted into two areas, with each area containing 20 stages, for a total of 1240 stages. Each world additionally contains three challenge levels which reward players with coins upon completion. Clearing an area will grant a 30-minute infinite play heart. Clearing the world's first area rewards a coin or assistant, while clearing the world's second area, represented by a Goal Pole, rewards a staff ticket and a silver medal. If they earn all stars in a world, they earn a gold medal for that world; and clearing a special stage in a world rewards a platinum medal, 1000 coins and a doctor. In every special stage, there are blue, yellow, and pink viruses, except in World 13, where the red virus replaces the pink one. Several of the worlds' designs take some inspiration from the New Super Mario Bros. series.

	Heart	Hearts serve as the players' energy meter in stage mode. Hearts get depleted whenever players attempt a level; once players has exhausted their hearts, they cannot play levels. At the beginning of the game, players have an infinite amount of hearts, but after stage 20 players have limited hearts. A heart replenishes after 30 minutes, if they clear a level, or if they purchase five hearts with 10 diamonds. Players can receive hearts from friends as well. Players can purchase 60 minutes of infinite play with 30 diamonds. Extra hearts can be added to the total to exceed the limit except through refilling through the timer or receiving hearts from friends.
	Coin	Coins are the common currency of the game. Players earn coins by completing stages and gaining stars, with 50 coins gained for every star achieved. Every time a player completes a stage, the virus adjacent on the map turn into a bonus coin. In versus mode, players can earn coins after winning a match, earning more at higher tiers. 4,000 coins are used to purchase random doctors and assistants under the Staffing menu. Every 12 hours prior to version 1.3.0, players are gifted with bonus coins or a bonus item for logging in. Since version 1.3.0, players can earn coins by eliminating viruses in Daily Booster. Players can earn bonus coins by completing Doctor's Orders and possibly earning them in battle boxes.
	Diamond	Diamonds are the premium currency of Dr. Mario World. They can be used to purchase a wide variety of items, such as items that help out players in stage mode to new random doctors and assistants. They are obtained mostly from purchasing bundles of them with real money at the shop or possibly obtaining them from battle boxes or flying boxes. Linking to a Nintendo Account or a Facebook account the first time will also allow the player to claim 10 diamonds for each.
	Staff ticket	Staff tickets are used to purchase random doctors and assistants under the Staffing menu. Up to 99 of them can be stored at once.

Stage objects

Image	Name	Description
	Shell	When activated, shells destroy objects to the right and left of them in that order. Shells will not activate another shell. Empty Blocks will block a shell.

	Skill Charger	When activated, the doctor's skill meters are filled by 60 points.
	Brick Block	Matching next to Brick Blocks destroy them or reveal something hidden inside them.
	Empty Block	Empty Blocks serve as impermeable obstacles. Any projectile such as a shell or cannonballs cannot bypass them.
	Handy Box	Matching next to a handy box reveals a beneficial stage object.
	Ice	Objects that are half-frozen require one match to remove the ice. Fully frozen objects require two matches to remove the ice.
	Coin Block	Brick Blocks that contain three coins each. They are required to be collected to clear certain stages. When a Coin Block is completely exhausted of coins, it will turn into an Empty Block.
	Bubble	These objects float upward, and may contain viruses or other objects. Viruses or objects encased in bubbles will require the bubble to be popped before they can be eliminated or activated. They cannot pop if they are currently floating upward.
	Virus Coin	Coins that are required to be collected to complete certain stages. They are found behind viruses or various objects, and can only be collected if nothing is in front of them.
	Lock Block	When eliminated, they unlock viruses or objects behind the cages with the matching color.
	Floatie Virus	Viruses in an inner tube teleport to another part of the stage when eliminate. They require three matches to fully eliminate.
	Caged Coin	Coins that cannot be collected until the coin that unlocks the cage is collected.
	Dust Virus	Viruses hidden in dust that get revealed when a capsule is placed next to them or when an object is destroyed next to it. Other objects might be hidden in dust instead of viruses.
	Cloud	Clouds can hide viruses or objects, and will occasionally become transparent if an object is hidden as to reveal what it contains.
	Crate	Takes up to four hits to destroy, depending on its current state.
	Ice Fan	When an adjacent tile is matched, the fan turns on. Activating the ice fan again makes a random virus or certain objects that can be matched (such as a shell or exploder) half-frozen, and fully-frozen if the affected object is already half-frozen.
	Key	Keys are found within bubbles, and like bubbles will float upward until they hit a door. They unlock the doors which are required to clear the stage. Any obstacle obstructing the key's path must be disposed of in order to make it reach the door.
	Door	Doors cannot be eliminated unless the key below it reaches the door; after both are united, the door is removed from the stage.
	Colorful Crate	A capsule match that share a color with the border of the crate are only able to destroy the crate.
	Capsule Plus	Matching with this object adds that amount of capsules or number of seconds remaining depending on the number marked.
	Flask	The flask fills when not eliminating stage objects after a capsule lands. The flask shoots out random objects after the flask is full. The objects shot out from the flask may be different between stages.
	Barrier	Switches back and forth between on and off after a capsule landed without making a match. Barriers can only be eliminated when they are currently switched off.
	Barrel	Requires a match to damage it if undamaged, or broken entirely if damaged. Barrels can contain viruses or objects in which the player can see if damaged, but the objects within cannot be interacted with until the barrel is completely broken.
	Bubble Machine	When an adjacent tile is matched, the machine turns on. Activating the bubble machine again traps a random virus or certain objects that can be matched (such as a shell or exploder) in a bubble.
	Pop Cannon	When activated, cannonballs will fire above and below the cannon, destroying objects within that column. Empty Blocks will block cannonballs.

Main article: Virus Vid

To promote Dr. Mario World, Nintendo released a series of short videos on social media featuring the viruses performing various activities, beginning on June 18, 2019 and ending on July 10, 2019, on a daily basis.

Animal Crossing: Pocket Camp

Pricing

Diamonds obtained by purchases come in two types: purchased diamonds and bonus diamonds. Purchased diamonds are tied to the device that is used to purchase them and are thus not transferrable to another device, while bonus diamonds are retained within the player's save. The rate of purchased diamonds is 10 diamonds per US $1 (currency varies by region), while bonus diamonds are added in for diamonds bought in higher quantities. Prior to the game's discontinuation, diamonds were made unavailable for purchase starting from July 28, 2021.

Reception

Critical reception

At launch, Dr. Mario World received generally mixed to somewhat negative reviews. Critics were somewhat divided but leaned positively on its puzzle aspect and its multiplayer mode, but near unanimously criticized its microtransactions and its online requirement. It currently holds a score of 58 on Metacritic based on seventeen reviews and a score of 55.94% on GameRankings based on eight reviews.

Chris Carter of Destructoid gave the game a 6/10, praising the accessibility and puzzles the game has to offer, but criticized the microtransactions, claiming "I've been playing mobile games consistently since Flight Control in 2009; so you could say I've had many encounters with energy systems and the like. The situation is definitely case-by-case, nuanced, and depending on the game the juice can absolutely be worth the squeeze. But seeing cute Super Mario characters reduced to this, with all of the psychological tricks in the book thrown in, is depressing. Just energy, just "you can finish this hard level if you pay," or just gacha would have been a lot as it is." In a review without a score, Ben Bertoli of IGN expressed skepticism over the change in gameplay compared to the previous entries in the series, and was slightly more critical of the microtransactions, stating "While it doesn't make it unplayable, to be sure, it makes it very clear from the get-go where this Dr. Mario's priorities lie". He concluded that it was still a fairly decent game to play for those who enjoy puzzle games. In a negative review, Glen Fox of Gamezebo gave the game a 2/5, criticizing practically everything about the game; he called the puzzles "artificial difficulty" and "uninspired", and raised a larger furor over the microtransactions, stating that he never expected Nintendo to engage in such practices.

In contrast to other critics, Chris Scullion of Nintendo Life gave the game a positive review and a score of 8/10, praising mainly the multiplayer mode. While he agreed with other critics that the single-player mode had too many microtransactions, he believed that the gameplay was fitting for a mobile device, and believed the multiplayer mode would be the game's highlight.

On the Google Play storefront, Dr. Mario World currently has an average user score of 3.9 out of 5, while on Apple's App Store, it has an average user score of 4.5 out of 5.

Reviews
Release	Reviewer, Publication	Score	Comment
iOS	Chris Carter, Destructoid	6/10	"It's a shame Nintendo cut and ran with microtransactions after one misstep — their first, no less — in the mobile market. Super Mario Run's "buy the entire game" concept likely would have worked at a different pricepoint, or perhaps it was worth experimenting further instead of hitching their wagon to one of many runners in an already-bloated runner market. Instead we now have energy meters and gacha-gambling in nearly every mobile release; an extreme 180 compared to the original strategy. Dr. Mario World had plenty of potential to be added to my list of regular mobile games, but I literally can't play it as often as I'd like for that to happen."
iOS	Glen Fox, Gamezebo	2/5	"And this is Nintendo we're talking about. We'd expect this sort of morally bankrupt behaviour from the vast majority of mobile developers and publishers that are out to make a quick buck, but not from Nintendo. But as bad as that is alone, our biggest disappointment is down to the gameplay itself, which is so bog standard and dull that we already feel like we've seen enough on day one. That's the most damning indictment of all."
iOS	Ben Bertoli, IGN	N/A	"Based on what I've played so far, Dr. Mario World feels like a decent spin on the decades-old series. It's unfortunate that its attempts to keep things fresh and fun are a bit overshadowed by its overzealous options and annoying microtransaction-based roadblocks. That said, if you enjoy puzzles and pretending to have a medical degree, Dr. Mario World isn't the worst choice."
iOS	Chris Scullion, Nintendo Life	8/10	"Dr. Mario World is very much a game of two halves. The single-player mode is fun in short bursts and short bursts only: lengthier sessions are impossible without regularly dropping real cash on it. Meanwhile, the multiplayer is an unrestricted delight, and the steady stream of available players means it could become your next obsession. Most importantly, both modes are built around a legitimately entertaining touchscreen twist on the standard Dr. Mario gameplay that makes plenty of changes, but clever ones that take the mobile format into account. It isn't proper Dr. Mario, then, but – assuming you can keep your wallet in your pocket – what it is isn't half bad."

Sales

Bar graph demonstrating sales and downloads of Dr. Mario World in the first 72 hours compared to other Nintendo properties.

Dr. Mario World has received 2 million downloads in the first 72 hours of its launch. It additionally received $100,000 from its in-app purchases. While it had only half of the downloads Super Mario Run had in the same time window, which was exclusive only to iOS at launch, and it is the lowest grossing Nintendo mobile game at this launch window, Dr. Mario World's revenue is comparable to other games in its genre such as Candy Crush Friends Saga; Dr. Mario World generated 75% of the revenue compared to Candy Crush Friends Saga's $137,000 in the same markets.

Dr. Mario World has reached 5 million downloads globally and players have spent $500,000 on in-app purchases in its first week, which is comparable to the top 25 puzzle games in Dr. Mario World's genre; Toon Blast from Peak Games, for example, grossed approximately $325 million in 2018, yet saw just $90,000 in its first week. Dr. Mario World charted as the #1 free iPhone app in Japan and #6 in the US.

As of July 28, 2021, this game is reported to have made $13.9 million in its entire lifespan and 13 million installs, the worst performing out of Nintendo's mobile titles excluding Miitomo.

Mobile app store description

Match 3 puzzle versus viruses!

■ Use your puzzle skills to eliminate pesky viruses!

• Match capsules with viruses and watch them disappear! Simply match three objects of the same color vertically or horizontally to clear them.
• Luckily, Dr. Mario and friends have virus-busting skills, and you can use leftover half-capsules to strategically zero in on especially meddlesome viruses.
• Take your time, because each puzzling configuration of viruses must be cleared using a limited number of capsules. Keep calm to plan your approach, and you'll rid Dr. Mario's world of viruses in no time!

■ Paging Dr. Mario!

• A colorful cast of viruses has Dr. Mario's world in a panic! Dr. Mario and friends have put on lab coats and grabbed capsules! Now they're ready to eliminate those unruly viruses.
• Dr. Mario isn't the only one on call—Dr. Peach, Dr. Bowser, and others are on duty. Staff up with assistants like Goomba, Koopa Troopa, and Buzzy Beetle to help your doctors out with additional skills.
• Doctors and assistants have various virus-busting skills, so experiment to find a combination that suits your style and pace.
• Hundreds of stages over many different worlds are ready for you to save! New worlds, new doctors, and more will be delivered on a regular basis.

■ Play together with friends and family around the world!

• You're not in this alone—send and receive stamina-giving hearts to use in stage mode! Then, show off your puzzle-solving progress.
• In versus mode, you can turn up the intensity on your virus-busting by challenging others to a one-on-one showdown—without using hearts!
• Find the right combo of doctor and assistants and aim for victory online to earn battle points and increase your tier!

Pre-release and unused content

Unused assets have been extracted from the game, showing Cooligan, Dino Piranha, Freezie, Ice Bro, Lava Bubble, and Whomp assistants, and text strings for Magikoopa and King Kaliente assistants. A tutorial image involving an asteroid game mechanic is present in the game's files, but it goes unused since the mechanic is not incorporated into the game. The asteroids would block four tiles (2x2) of viruses; once an adjacent row is matched, the asteroids would break, revealing the viruses.

There are also medals featuring Boo indicating future Clinic Events, a golden ticket to unlock costumes for characters, medals themed around Super Mario Galaxy, and a black, spiky, Fuzzy-looking creature wearing a surgical mask.
