'''''Super Mario Bros.: The Lost Levels''''', also known as '''''Super Mario Bros. 2''''', and alternatively '''''Super Mario Bros. 2: For Super Players''''' in the Japanese version of ''[[Super Mario All-Stars]]'' and '''''Super Mario Bros. for Super Players''''' in ''[[Super Mario Bros. Deluxe]]'', is a direct sequel to the [[Nintendo Entertainment System|NES]] game ''[[Super Mario Bros.]]'' It is the second entry in the [[Super Mario (series)|''Super Mario'' series]].<ref name=encyclopedia>{{cite|author=Sakai, Kazuya (Ambit), kikai, Akinori Sao, Junko Fukuda, Kunio Takayama, and Ko Nakahara (Shogakukan), editors|title=『[[Super Mario Bros.

The game was initially released in [[List of games by date#1986|1986]] for the Japan-only [[Family Computer Disk System]]. It uses a slightly altered version of ''Super Mario Bros.''{{'}}s engine, with some new features, altered graphics and new enemy behavior, and different, significantly more challenging levels. [[Nintendo]] of America originally deemed this game too difficult and too much like the original{{ref needed}} to sell well in {{wp|Western world|Western}} countries, so in order to prevent the early series from being associated with frustration and staleness, Nintendo adapted ''[[Yume Kōjō: Doki Doki Panic]]'' and released it as ''[[Super Mario Bros. 2]]''. This game was later released in Japan under the title ''Super Mario USA''.

The first time this game was released outside Japan was its remake in ''Super Mario All-Stars'', where it gained the title ''Super Mario Bros.: The Lost Levels'' in 1993. Then, as part of ''Super Mario Bros. Deluxe'', it was redone and renamed ''Super Mario Bros. for Super Players''. The original unaltered release was not available worldwide until the debut of the [[Virtual Console]], over two decades later.

==Story==
The story of ''Super Mario Bros.: The Lost Levels'' is identical to the first game and is said to be set in a "parallel world" to it.<ref name=Staff/><ref>{{cite|url=www.nintendo.co.jp/wii/vc/vc_smb2/vc_smb2_01.html|title=VC スーパーマリオブラザーズ2|language=ja|publisher=Nintendo|accessdate=May 31, 2024}}</ref> The following text is translated from the Japanese instruction booklet.<ref>{{cite|url=gamingalexandria.com/fds/Super%20Mario%20Bros%202/Super%20Mario%20Bros%202%20-%20Manual.pdf|title=''Super Mario Bros. 2'' Disk System instruction booklet|format=PDF|page=3}}</ref>
<blockquote>
''One day, the peaceful kingdom where [[Toad (species)|Mushroom]]s live was invaded by the tribe of the huge turtle [[Bowser|Koopa]], whom possesses powerful magic. Said magical power transformed all the quiet Mushroom People into rocks, [[Brick Block|brick]]s and [[horsetail]]s among other forms, and the [[Mushroom Kingdom]] fell into ruin.''

''The only one who can undo this magic on the Mushrooms and revive them is the Mushroom Kingdom's own [[Princess Peach]]. She is presently in the hands of King Koopa.

''[[Mario]] has stood up to defeat the [[Koopa (species)|Turtle Tribe]], rescue Princess Peach, and rebuild the peaceful Mushroom Kingdom.

''The Mario in the TV is you. Only you can bring this adventure quest (expedition) to a conclusion.
</blockquote>

==Gameplay==
[[File:SMB2 Famicom Title Screen.png|thumb|left|upright=1.3|The title screen of ''Super Mario Bros.: The Lost Levels.]]
''Super Mario Bros.: The Lost Levels'' is divided into 13 new worlds of the [[Mushroom Kingdom]], each of which have four levels like in ''[[Super Mario Bros.]]'' Mario and Luigi have to get to the end of the level by jumping over various gaps and avoiding or defeating the members of the [[Koopa Troop|Turtle Empire]] on their way. The Mario Bros. can use several platforms (some of them collapse when Mario or Luigi lands on them), stairs in the level, as well as [[Trampoline|Jumping Boards]]. There are also [[Warp Pipe]]s along the way, some of which Mario can enter to visit various secret coin rooms before returning to the level, a bit further ahead than when he left. At the end of each level, a castle stands with a [[Goal Pole|flagpole]] nearby. When Mario reaches the flagpole, he takes down the enemy flag and enters the castle, completing the level. The higher the spot that Mario hits the flagpole, the more points he receives. 

Unlike ''Super Mario Bros.'', ''Super Mario Bros.: The Lost Levels'' does not have two-player mode in the game. Mario or Luigi has to be played alone. Mario retains the same abilities as ''Super Mario Bros.'', but Luigi returns with the ability to jump higher than Mario can (which is retained in ''Super Mario Bros. 2'' and some other ''Super Mario'' games). On the downside, Luigi has slippery traction, so he could prove to be unruly at times.

''Super Mario Bros.: The Lost Levels'' includes the same enemies from ''Super Mario Bros.'': [[Goomba]]s, [[Koopa Troopa]]s, [[Buzzy Beetle]]s, [[Koopa Paratroopa]]s, [[Bullet Bill]]s, [[Hammer Bro]]thers, and leaping [[Cheep Cheep]]s. All these enemies can be defeated when Mario jumps on them once, except for Koopa Troopas and Buzzy Beetles, which now run faster than in ''Super Mario Bros.'' and hide in their shell when jumped on, which Mario can kick to defeat other enemies and hit blocks or [[Brick Block|brick]]s. Koopa Paratroopas lose their wings and fall to the ground when Mario or Luigi jumps on them. Other enemies include [[Piranha Plant]]s (including new red Piranha Plants, which have replaced green ones in later games) found in pipes, the [[Spiny]]-throwing [[Lakitu]]s and the [[Hammer Bro]]thers. There are a few levels which take place underwater. In the water, Mario can swim freely from the top to the bottom of the screen. The enemies in underwater levels are [[Blooper]]s and [[Cheep Cheep]]s, with the inclusion of Goombas, Koopa Troopas, Buzzy Beetles, Koopa Paratroopas, Hammer Brothers, [[Lava Bubble]]s, [[Fire Bar|Fire-Bar]]s, and Piranha Plants; Mario can only defeat these creatures by shooting them with [[fireball]]s. In some levels, Bloopers are found floating in the air.

[[File:SMBLL World 3-1 Warp Zone.png|thumb|left|upright=1.3|[[Fire Mario|Fire Luigi]] in [[World 3-1 (Super Mario Bros.: The Lost Levels)|World 3-1]]'s backwards [[Warp Zone]].]]
Mario or Luigi can get special power-ups out of [[? Block|?]]s or, uncommonly, bricks. Most of the ?s in which Mario can find these items are visible, but some are hidden and only become visible when hit from below. With the [[Super Mushroom]], he turns into [[Super Mario (form)|Super Mario]]. As Super Mario, he can survive the hit of an enemy one time, at the cost of turning back to [[Small Mario]]. He may also destroy empty bricks by jumping beneath them. ''Lost Levels'' introduces a harmful version of the Super Mushroom, the new [[Poison Mushroom]]s, which injure Mario or Luigi by simply touching one. Additionally, he can also get the [[Fire Flower]]. With the Fire Flower, Super Mario turns into [[Fire Mario]], which allows him to shoot fireballs at enemies to defeat them from a distance. With the [[1-Up Mushroom]], he gains a life; he can also get an extra life by collecting 100 [[coin]]s. With the rarest item of all, the [[Super Star]] (which can only be found in bricks), Mario turns invincible for short of time and can kill enemies by touching them. As with ''Super Mario Bros.'', with the exception of coins, only one item can appear on the screen, and when a new item appears, the previous one will disappear.

If Mario takes a hit or Poison Mushroom while Small, falls down a [[pit]], or if the [[Time Limit]] runs out, he loses a life and restarts the level. The point where Mario continues depends on his progress through the level before getting defeated; either from the beginning, or at one of several invisible "checkpoints" throughout the level.

The fourth level of each world plays inside a castle. They are usually filled with [[Fire Bar|Fire-Bar]]s and [[Lava Bubble]]s. At the end of a castle level, Mario is confronted with a [[Impostor Bowser|fake Bowser]] in every world except [[World 8 (Super Mario Bros.: The Lost Levels)|World 8]], where the real Bowser is confronted. To defeat a fake Bowser or the real Bowser, Mario has to either touch the [[axe]] to destroy the bridge, causing either the fake Bowser or the real Bowser to fall into the [[lava]], or hit Bowser with a number of fireballs, which produces the same result and reveals the true forms of the fakes.

After defeating a fake Bowser, Mario frees one of the seven [[Toad (species)|Toad]]s from the castle, at which point they say their iconic sentence: "Thank you Mario/Luigi! But our princess is in another castle!" and Mario proceeds to the next world. At the end of the castle in World 8, Mario or Luigi frees the grateful [[Princess Peach]] and completes the adventure.

Unlike the first game, there are hidden worlds to discover. Playing through the game without [[Warp Zone|warping]] forward takes the player to the [[World 9 (Super Mario Bros.: The Lost Levels)|Fantasy World]]. Completing the game eight times also unlocks Worlds A-D, with Princess Peach waiting to be rescued from a fake Bowser (the actual Bowser in ''Super Mario All-Stars'' version) in the last level.

==Differences and additional features==
Although the mechanics in ''Super Mario Bros.: The Lost Levels'' adhere closely to those of ''Super Mario Bros.'', the game does feature some significant changes and additions.
===Graphical and sound additions and changes===
*The background graphics, block tiles, and ground tiles are different (mountains now have jagged slopes, cloud and bushes have faces, horsehair plants/trees are now segmented, fences and lifts are now mushrooms, ground is rockier, bricks have shading, etc.).
*Mushroom sprites (including Super Mushrooms, Poison Mushrooms, and 1-Up Mushrooms) are changed to have eyes, a feature that has stuck with the franchise since.
*The giant mushroom platforms (found in 4-3 and the 4-2 Warp Zone of ''Super Mario Bros.'') are changed into a new cloud shape that is not found in any other port of any of the 8-bit [[Super Mario (franchise)|''Super Mario'' games]], and form the level theme of World 8-3 and World A-3 (actual ''Super Mario Bros.: The Lost Levels''-style mushroom platforms would appear in ''[[All Night Nippon: Super Mario Bros.]]'', where they now have segmented stalks). Similarly, the grass platforms found in every other third level except for World D-4 now have a fringe-like appearance. 
*A skidding sound for Mario and Luigi's sliding is added. This would later be reused in ''[[Super Mario Bros. 3]]''.
*An animation when Mario comes out of a pipe into water is added.
*Shadows are added to the text font.
*Digits are one pixel shorter than the ones in the original game, and the "0" is shaped like the "O", rather than the rounder, slanted version seen originally. ''[[VS. Super Mario Bros.]]'' and ''All Night Nippon: Super Mario Bros.'' also use the ''Super Mario Bros.: The Lost Levels'' font, while ''[[Super Mario Bros. Special]]'' retains the ''Super Mario Bros.'' font.
*The "[[Ending (Super Mario Bros.)|Ending]]" theme has a second verse four steps above the original pitch, and uses the FDS's hardware capabilities to make it richer in sound. It was first composed as the ending theme of ''Super Mario Bros.'', before being shortened due to storage limitations.<ref>{{cite|publisher=shmuplations|url=shmuplations.com/kojikondo|title=Koji Kondo – 2001 Composer Interview|accessdate=May 31, 2024}}</ref> A similar version appeared earlier in ''VS. Super Mario Bros.''
*Princess Peach is given a new sprite.

===New game features===
*[[Poison Mushroom]]s are introduced. Touching one is equivalent to colliding with an enemy, except the mushroom is consumed as usual. They can be found in either [[? Block|?]]s or invisible blocks. Their color palette matches the Goombas of that level (brown on overworlds, blue in undergrounds, gray in castles).
*Red Piranha Plants are introduced, a more aggressive variant of the usual green Piranha Plant that attacks even if the player is standing next to their pipe. They stop attacking only if the player is anywhere above the pipe (except if on the two outermost pixels of its edges). These first appear in World 4, completely replacing green Piranha Plants which no longer appear.
*Upside-down pipes are introduced, appearing first in World 5.
*Red Piranha Plants may be found in upside-down pipes. They attack and retreat more frequently than those in right-side up pipes, and there is no way to stop them from attacking (since the player cannot stand on top of their pipe; they continue to attack even if the player stands directly underneath their pipe). These also appear in underwater stages.
*A strong [[wind]] blows in certain parts of some levels. It usually blows the player forward, enabling longer jumps but making it difficult to space them.
*While the original ''Super Mario Bros.'' only had three Warp Zone areas, ''Super Mario Bros.: The Lost Levels'' features a total of 11, all of which have only one destination pipe. Two of them are fake, and now take Mario back to a previous world: 3-1 to 1-1 and 8-1 to 5-1. Like World 4-2 of the original game, some levels have more than one Warp Zone location.
*Two-player mode has been removed, and the player can instead choose between Mario and Luigi on the title screen. Mario controls as in ''Super Mario Bros.'', while Luigi can jump higher than Mario, but has significantly worse traction. These characteristics would be carried over to many future ''Super Mario'' games, including ''[[Super Mario Galaxy]]'', ''[[Super Mario Galaxy 2]]'', ''[[Super Mario 3D Land]]'', and ''[[Super Mario 3D World]].
*If the player beats the game while completing all 32 of the game's standard levels without using any Warp Zones, they unlock World 9, a secret world. They have only one life to complete it with: if they fail, they are brought back to the main menu after getting a special Game Over message, and if they succeed, the world loops back on itself upon completion, meaning they can keep playing it until they die or decide to quit the game. The world features bizarre underwater landscapes not found in any other level, such as an underwater [[Goal Pole]] and castle. In the ''Super Mario All-Stars'' remake, the player may keep any lives they had left after World 8-4. All secret worlds were removed in the ''Super Mario Bros. Deluxe'' port.
*In the original version and Virtual Console releases, the game adds a star on the title screen each time the player beats World 8-4. The number of stars the player earns is saved on the disk, and the title card can display up to 24 stars.
*If the player earns a total of eight stars on the title card, they can unlock four more secret worlds, Worlds A through D, by holding the {{button|nes|A}} button at the title screen (or the {{button|gba|B}} button in the GBA version) before pressing Start. In the ''Super Mario All-Stars'' re-release, the levels may be accessed after just one successful playthrough, beginning automatically after World 8-4 (or 9-4 if the player unlocks World 9). All secret worlds were removed in the ''Super Mario Bros. Deluxe'' port.
*Green [[Super Spring]]s are introduced, appearing in Worlds 2, 3, 7, B, and C. These bounce Mario/Luigi so high that he disappears from view for several seconds, allowing the player to cover great distances without touching the ground but also making it very difficult to track his trajectory.

===Tweaked game features===
*A significant physics modification is added: Mario now bounces much higher after stomping on an enemy, and Luigi bounces even higher than Mario now does. This extra height is sometimes critical to clearing large gaps. If Mario or Luigi manages to stomp the top of an enemy while moving upwards at the right trajectory, the changed physics cause them to soar very high, sometimes off the top of the screen. This "Super Jump" would later be properly introduced in ''Super Mario Bros. 3''.
*Invisible blocks may now hold any kind of power-up (instead of solely 1-Up Mushrooms, like in ''Super Mario Bros.''), including Poison Mushrooms. These are either put in secret areas to aid the player, or (in the case of Poison Mushrooms) sometimes placed in locations easy to accidentally hit in order to obstruct the player.
*[[Blooper]]s can float above water. They behave the same way they do underwater and can be stomped for 1000 points.
*[[Koopa Troopa]]s (and more rarely, a few other enemies) can be found in the water in some levels, such as World 3-2. They walk more slowly than usual and like other underwater enemies, cannot be stomped (Mario/Luigi instead take damage; they cannot be defeated without a [[Fire Flower]] or [[Super Star]]). Due to the palettes assigned to the underwater stages, the green enemies appear gray (they are still colored normally in the ''Super Mario All-Stars'' version). Additionally, this also renders underwater Buzzy Beetles invincible, as Buzzy Beetles cannot be defeated with fireballs, and cannot be stomped underwater.
* The "right path, wrong path" system now occurs in some non-castle levels, looping the level until the correct path is chosen. These levels include World 5-3 and World 7-2.
*In Worlds 7 and 8, [[Hammer Bro]]thers now continuously charge forward while still throwing [[Hammers]], making them extremely difficult to dodge. If Mario passes over them, they turn around and then behave normally (they continue to jump and throw hammers, but no longer run). In ''Super Mario All-Stars'', this behavior also occurs in Worlds A-D. Hammer Brothers also occasionally appear underwater.
*[[Lakitu]]s now sometimes appear underwater, along with [[Spiny|Spinies]]. In certain levels, they also appear at lower altitudes, making them easier to stomp.
*An [[Bowser's Brother|unusually-colored version of Bowser]] can be found in the corridors of two castles. He has a darker, greenish blue coloration, similar to [[Koopa Troopa]]s and [[Piranha Plant]]s found in cave or castle levels, and does not stand on a bridge over lava. The player can avoid this Bowser without defeating him. In the ''Super Mario All-Stars'' version, encountering this enemy cues the SNES-exclusive boss music until finishing the level. These palette changes are due to not being close to the axe, where the overworld green palette is used instead. Unlike the [[Impostor Bowser|fake Bowsers]] in Worlds 1-7 and Worlds A-C, these do not change into generic enemies when defeated (with five Fireballs as usual); they will still look like the real Bowser.
*[[Beanstalk]] vines can lead to not only a [[Coin Heaven]] or a [[Warp Zone]], but even to the flagpole.
*Luigi's increased jump height sometimes enables him to jump over the Goal Pole. In a few cases, this leads to a Warp Zone beyond the pole; in most other cases, the screen simply stops scrolling after the pole. It is no longer possible to get stuck behind the Goal Pole like it was in the original ''Super Mario Bros.''
*Fireworks are no longer triggered by having the last digit of the timer be 1, 3, or 6, but rather by having the last digit of the timer match the last digit of the coin counter. Additionally, if both digits of the coin counter match the last digit of the timer, Mario/Luigi receives a 1-Up.
*In overworld and underground levels, some Piranha Plant pipes are now flush with the floor rather than extending above it, making them more difficult to notice and avoid.
*In addition to the obvious Poison Mushrooms, many actual power-ups are now traps: in castles with ceilings, a Super Mushroom may make Mario too tall to make some long jumps (as his head hits the ceiling and causes him to fall into a pit or lava); and in athletic levels, a Super Star may prevent Mario from stomping atop Koopa Paratroopas in midair to complete some extra long jumps (causing him to fall into the pit below).
*Holding A+Start on the title screen is no longer a continue code; instead, the player is directly given the option to Continue on the Game Over screen, and cannot return to the title screen without being forced to restart from World 1-1. (As the secret World 9's Game Over screen features a special message in place of any options, the player effectively cannot use any continues at all in that world; this does not hold true in ''Super Mario All-Stars''.)
**In the GBA version, holding A+Start on the title screen once again allows the player to continue, but only from Worlds 1 to 8. This is saved (along with their high score) even when the game is powered off, if the player saves their high score beforehand. This change also makes it possible to switch between Mario or Luigi without having to restart on World 1, which was not possible in the FDS version.
*After beating the game, pressing B on the title screen no longer allows the player to start from any world, and there is no "[[Hard Mode|new quest]]" where the player travels through the same levels but with tougher enemies. (The latter is essentially replaced by the secret worlds A-D.)
**The ''[[Game & Watch: Super Mario Bros.]]'' version of the game restores the world selection feature, allowing the player to access the highest world achieved in gameplay and all prior ones. Unlocking World A only does not unlock World 9 on the world select feature.
*A new ending cutscene, reused from ''[[VS. Super Mario Bros.]]'', is included: After Bowser (or fake Bowser in World D) is defeated, Mario/Luigi finds Peach inside a separate room instead of simply being in the area behind the Bowser battle bridge, who then thanks him by reciting a poem, followed by the sky lighting up and turning blue and the seven Toads Mario/Luigi rescued earlier on reappearing and circling him and Peach (five of them are depicted floating in mid-air) and exclaiming "Thank you{{sic}} Mario/Luigi!" Much like the case with Bowser's wristbands, the ending cutscene confirms the fact that Peach and the Toads' eyes appearing as black pixels is due to them actually being transparent and formed from the background color due to the NES' color palette being limited to having just three colors each. The ending is also reused after completing World D-4, despite Mario/Luigi only rescuing just three Toads there, as well as in ''All Night Nippon: Super Mario Bros.'', where all of the Toads are replaced with caricatures of celebrities (again, even in World D-4) and Peach dressed as a geisha. In ''Super Mario All-Stars'' version, however, the ending is the same as the altered ending in the ''All-Stars'' version of ''Super Mario Bros.'', which instead features Mario rescuing Peach from a cage suspended over lava.

===Bosses===
Like the original ''Super Mario Bros.'', a [[boss]] occurs in the fourth level of each world within the final room of the [[castle]]. The only exception is [[World 9 (Super Mario Bros.: The Lost Levels)|World 9]], whose boss is in [[World 9-3 (Super Mario Bros.: The Lost Levels)|9-3]] above ground. The boss is on a bridge suspended above a pool of lava. Touching the ax at the opposite corner of the bridge makes it fall away and defeats the boss, but striking one with five [[fireball]]s as [[Fire Mario|Fiery Mario]] defeats it as well. Defeating it this way awards the player with 5000 points. Once defeated, Mario transitions to a narrow corridor where a captive is held. In the first seven [[world]]s, this captive is a [[Toad (species)|Toad]] that directs Mario further along his journey. In [[World 8 (Super Mario Bros.)|World 8]] and [[World D-4|D-4]], [[Princess Peach|Princess Toadstool]] is the one rescued. In most boss rooms, Lifts, Normal Blocks, Podoboos, and Fire-Bars appear alongside the boss as well.

===Power-ups===
Items that transform Mario's appearance and give him unique abilities. All of these items are held within blocks and must be jumped under to be released. It is not inherently apparent which block contain which power-ups, and breaking them does not grant Mario their abilities. He must touch the power-ups directly once they are expelled. Touching any power-up also awards Mario 1000 points. Forms that share a column look the same for Mario and Luigi.

Touching one transforms Small Mario into Super Mario, a form twice as tall and capable of breaking Normal Blocks. Subsequent encounters with blocks intended to contain Mushrooms instead release Fire Flowers when struck in this form. Receiving damaging reverts Super Mario back into his Small form. He retains his Super form across levels if he reaches flagpoles as Super Mario.

|align=left|Making contact with a Fire Flower transforms Mario into Fiery Mario. In this form, Mario can toss projectile fireballs with {{button|nes|a}} that bounce along the ground. Most enemies are defeated when hit. Fiery Mario also has all the benefits of Super Mario, and similarly retains this form if he completes the level in it. As in the original ''Super Mario Bros.'', Mario reverts to his Small form if hit as Fiery Mario.
|-
|[[File:SMB Sprite Super Star.png]]<br>[[Super Star|Star]]

|align=left|Stars are rare power-ups often hidden in invisible blocks. When released, they bounce in the opposite direction from Mario. When grabbed, Mario is transformed into Invincible Mario for thirty seconds. In this state, Mario is largely indestructible and defeats enemies on contact. Contact with the Star does not wholly replace the form Mario was already in (i.e., Mario remains small if one is touched while in his Small form, and he can still toss fireballs if he is in his Fiery form.) Invincible Mario cannot be carried over to subsequent levels.

==Re-releases==
An emulation of ''Super Mario Bros.: The Lost Levels'' was released in Japan for the [[Game Boy Advance]] as part of the [[Classic NES Series|''Famicom Mini'']] series on August 10, 2004.

It was released on the [[Virtual Console]] in Japan on May 1, 2007 for the [[Wii]], on July 25, 2012 for the [[Nintendo 3DS]] and the [[Wii U]] in Japan on August 8, 2013. It was also released for the Wii in Europe and Australia on September 14, 2007 along with ''[[Mario's Super Picross]]'' and ''{{wp|Neutopia II}}'' as the part of the Japanese {{wp|Hanabi Festival}}, and in North America on October 1, 2007, making the first time the original version of the game was available to most international audiences. It costs 100 [[nwiki:Wii Points|Wii Points]] more, as usual for imported games. Unlike other games, however, it was removed from the European/Australian [[Wii#Wii Shop Channel|Wii Shop Channel]] on October 1, 2007, before being re-added permanently on August 22, 2008. It became available for the Nintendo 3DS outside Japan on December 27, 2012. It was released for the Wii U in Europe and Australia on January 23, 2014 and in North America on March 13, 2014.

The Wii release requires 23 blocks (2.9 MB) to be installed, while the Wii U release requires 15 MB to be installed.

It was released on the [[Nintendo Entertainment System - Nintendo Switch Online]] application for the [[Nintendo Switch]] in April 2019.

It is included in ''[[Game & Watch: Super Mario Bros.]]'', which was released on November 13, 2020.
===Remakes===
====''[[Super Mario All-Stars]]''====
[[File:SMAS LL World C-1 Screenshot.png|thumb|upright=1.1|Snowy [[World C-1]] in ''Super Mario All-Stars''.]]
The ''Super Mario All-Stars'' (as well as ''[[Super Mario All-Stars + Super Mario World]]'' and ''[[Super Mario All-Stars Limited Edition]]'') version of this game had a few differences from the original:
*''Super Mario Bros.'' and ''Super Mario Bros.: The Lost Levels'' do not have the same graphics as each other to begin with. For instance, the ground is covered by blocks in most of the levels of the original, whereas the ground is mainly covered by dirt in this version. In ''Super Mario All-Stars'', the graphics of all the games were improved, and ''Super Mario Bros.: The Lost Levels'' was made to look exactly the same as the graphically-improved version of ''Super Mario Bros.'' released on the same cartridge. The endings of both games were also made uniform.
*Many levels that had snow in the original Japanese ''Super Mario Bros. 2'' do not have it in the ''Super Mario Bros.: The Lost Levels'' edition: 3-3, 7-1, 7-2, 7-3, 8-1, C-3, D-1, D-2, and D-3. Likewise, one level that did not have snow originally has snow in the ''Super Mario All-Stars'' remake: C-1. However, the snow is only an aesthetic difference.
*If the player decides to continue after a Game Over, they will start over at the beginning of the current [[level]], rather than the current [[world]] as in the original version.
*The game can be saved at any time. Unlike in ''Super Mario Bros.'' on the same cartridge, the game remembers the exact level the player is on, and not just the world. This is because the game is much harder than the original.
*In the secret section of World 1-2 (where the player enters the pipe to World 4), the water pools were replaced by lava. However, the effects are the same: if Mario falls in, he loses one [[Extra life|life]]. Similarly, the water in the first pit encountered in the level (after the Koopa Paratroopa) is removed in the SNES version.
*The player would get a positive or negative audio cue to indicate if they were going the right or wrong way in the mazes of World 3-4, 6-4, and 8-4, making navigation slightly easier in those levels.
*In World 8, the [[Hammer Bro]]thers perpetually charge at the player. On the SNES, this behavior was added to Worlds [[World 7 (Super Mario Bros.: The Lost Levels)|7]], [[World 9 (Super Mario Bros.: The Lost Levels)|9]], and [[World A|A]] through [[World D|D]] as well.
*The castle walls of World 9-3 (whose background is sky blue instead of black) are now recolored brown instead of gray like in the original (and in the ending cutscene).
*Players only have to beat the game once to reach Worlds A through D.
*In the original game, Bowsers use hammers in only Worlds 6-9. The SNES remake gives them hammers in Worlds A-D, as well. Strangely enough, these Bowsers lose [[Bowser's Flame|Bowser's Fireball]].
*Super Springs in World B have been replaced with regular [[Trampoline|Spring]]s.
*The fake Bowsers in Worlds A-C now have new true forms (a red Koopa Troopa, a Cheep Cheep, and a Bullet Bill, respectively), and the fake Bowser's death animation in World D is changed to make him into a real Bowser.

====''[[Super Mario Bros. Deluxe]]''====
''Super Mario Bros. Deluxe'' was marketed as a [[Game Boy Color]] enhancement of ''Super Mario Bros.'', but if a player gets on the high score table with 300,000 points or more, a Luigi head appears on the main menu. Players may select the Luigi head to play ''Super Mario Bros.: The Lost Levels'' under the name of ''Super Mario Bros. for Super Players''.

In this game, as in the ''Super Mario All-Stars'' version, the player may save and resume at any level. However, most changes removed features from the original release. This remake removes the graphical changes from ''Super Mario Bros.: The Lost Levels'' and thus looks just like ''Super Mario Bros.'' Additionally, Luigi's higher jump and lower traction are removed, as is wind. As a result of the lack of wind, some levels are modified to make the jumps possible. Another change is the removal of Worlds 9 and A-D, although they are all at least somewhat present within the game's coding.

==Descriptions==
'''Wii Shop Channel'''

"''Originally released in Japan as Super Mario Bros.® 2, this game has previously made only brief cameo appearances in the Western hemisphere. Now available on the Virtual Console in all of its original splendor, Mario fans will appreciate the familiar look and feel of the game, while finding that its updated game play creates an entirely new challenge. No longer content just to wear different-colored overalls, Mario and Luigi also possess different skill sets (Mario can stop quicker, while Luigi can jump higher). In addition to the classic enemies already known to fans worldwide, there are also Poison Mushrooms, backward Warp Zones, and the occasional wind gust (which can help or hinder your progress) to take into account. And if that's somehow not enough, expert players can go looking for the game's secret worlds. So get ready to put your Mario skills to the ultimate test, and save the Princess again. Just don't be surprised if she's in another castle!''"

==Reception==
The Japanese ''Super Mario Bros. 2'' served as one of the flagship titles for newly released Famicom Disk System in 1986, alongside ''[[Zeldawiki:The Legend of Zelda|The Legend of Zelda]]''. ''Super Mario Bros. 2'' was intended to be a game for expert gamers that had mastered the original ''[[Super Mario Bros.]]'' and were looking for a new challenge. It was the most popular Famicom Disk System game, selling about 2.5 million copies. Japanese critics at the time, however, characterized the game as an "expansion pack" or "update" to the original rather than an actual sequel.{{ref needed}}

|align="left"|"''But is it worth shelling out the money again for what is essentially version 2 of Super Mario Bros.? If you're a fan, yes. The completely different levels, slightly changed visuals and Luigi mode make the game feel like a little more than "just an update". If you're not a big Mario fan, though, I would suggest sticking with the original (Unless you like extremely hard games). Another thing to take into consideration is that this game, in it's original NES/Famicom form, was never released in Europe and America. The All-Stars version had upgraded graphics and sound (And slightly lowered the difficulty), while the DX version cut out Worlds 9 and A-D. This means this is the first time you can own this game in it's original, complete form (Unless you live in Japan or imported a Famicom Disk System and the game!).''"

|align="left"|"''Those who hated The Lost Levels on its inclusion in Super Mario All-Stars, due either to its difficulty or lack of originality, may find that they have a new-found appreciation for this underrated gem. It's not without flaws, but when played in tandem with the Wii U's save state functionality in short doses to alleviate frustration, there's a lot to enjoy here. Some of the level design and intentional placement of obstacles and enemies is almost frighteningly devious, a sense of playful teasing that is perhaps sorely lacking from present-day Nintendo's 'games for everybody' line-up. Super Mario Bros.: The Lost Levels will constantly taunt the player with its level of challenge and meticulously sinister design, but those who enjoy triumph through adversity and can handle a little frustration will enjoy every second of it.''"

Super Mario Bros.: The Lost Levels is a lot like that.''"

==Staff==
Like the original ''Super Mario Bros.'', ''Super Mario Bros.: The Lost Levels'' does not feature a staff roll or any sort of credits. Unlike its predecessor, however, very little has been written about the game's development, leaving its precise staff composition a mystery. In a promotional interview for the [[Classics#NES Classic Edition|NES Classic Edition]], the game is referred to as [[Takashi Tezuka]]'s directorial debut.<ref>{{cite|author=Sao, Akinori|deadlink=y|archive=web.archive.org/web/20161111054427/http://www.nintendo.com/nes-classic/super-mario-bros-and-super-mario-bros-3-developer-interview|title=NES Classics Edition Developer Interview: SUPER MARIO BROS.™ & SUPER MARIO BROS.™ 3|publisher=Nintendo.com|language=en-us|accessdate=May 31, 2024}}</ref>

==Trivia==
*Dummied data for the game ''[[nookipedia:Doubutsu no Mori+|Dōbutsu no Mori+]]'' indicated that ''Super Mario Bros.: The Lost Levels'' (or, more accurately, ''Super Mario Bros. 2'') as well as ''[[NES Open Tournament Golf|Mario Open Golf]]'' would have been included as a playable Famicom game, but it ultimately was cut with not even a ROM or models available inside.<ref>{{cite|url=tcrf.net/Animal_Crossing#Removed_Games|title=''Animal Crossing''|publisher=The Cutting Room Floor|accessdate=May 31, 2024}}</ref>
*At the end of the ''[[Mario Kart 8]]'' April 30 Nintendo Direct, when the Nintendo fan pulls out his "Things to do before I die" list to write "Buy ''Mario Kart 8''", one of the other notes on the list is "Beat SMB2: The Lost Levels",<ref>{{cite|url=youtu.be/JbuJZP0_8iQ?t=2152|timestamp=35:52|title=Wii U - Mario Kart 8 Direct 4.30.2014|publisher=YouTube|accessdate=May 31, 2024|author=Nintendo of America}}</ref> a reference to how difficult the game is compared to other ''[[Super Mario (franchise)|Super Mario]]'' games.
*The worlds that take place at night (2 and 7) and the worlds with an underwater level (3 and 6) are the inverse of the worlds' placements in the original ''Super Mario Bros.''
*In the [[Family Computer Disk System]] version only, the disk drive is automatically activated at the end of Worlds 4 and 8. Additionally, after World 5 starts, if the player resets the game, the disk drive is activated and the game returns to the title screen.<ref>{{cite|url=www.nintendo.co.jp/software/smb2/material/pdf/smb2_manual.pdf|title=''Super Mario Bros. 2'' instruction manual|publisher=Nintendo|language=ja}}{{page needed}}</ref>
*The game uses a "brother byte" to determine the current brother's name and appearance. There are two valid brothers, [[Mario]] and [[Luigi]], and 254 invalid ones. Out of them, only three have names that are not glitched: Iolui, Uigiy, and Ariol.<ref>{{cite|author=@MarioBrothBlog|date=June 14, 2024|url=https://x.com/MarioBrothBlog/status/1801616946837823790|title="''Super Mario Bros.: The Lost Levels uses a "brother byte" to determine the current brother.
