It is a follow-up to the [[List of games by date#2006|2006]] [[Nintendo DS]] game ''[[New Super Mario Bros.]]''

In addition to the single-player experience, ''New Super Mario Bros. Wii'' also features a multiplayer mode for up to four players. This is the first side-scrolling ''Super Mario'' game to feature co-op and vs. modes at the same time, and the first one overall since ''[[Mario Bros. (game)|Mario Bros.]]'' It features more [[New Super Mario Bros. Wii#Items|items]] and more [[List of enemies|enemies]] than its DS predecessor. It is also the first title to support Nintendo's new [[Super Guide]] mode.<ref name="kotaku-superguide">{{cite|author=Totilo, Stephen|url=kotaku.com/kind-code-demo-shows-new-super-mario-bros-on-auto-pil-5374432|title="Kind Code" Demo Shows New Super Mario Bros on Auto-Pilot|date=October 5, 2009|publisher=Kotaku|accessdate=June 3, 2024|language=en}}</ref> The game introduces two new power-ups, the [[Propeller Mushroom]] and the [[Penguin Suit]], which turn characters into their [[Propeller Mario|propeller]] and [[Penguin Mario|penguin]] forms, respectively.

''New Super Mario Bros. Wii'' is the first 2D platformer ''Super Mario'' title to hit a home console since ''[[Super Mario World]]'' for the [[Super Nintendo Entertainment System|SNES]] (released 19 years prior). To date, the game has sold over 30 million copies worldwide, making it the fourth best-selling Wii game overall and the second best-selling ''Super Mario'' game on the system, after ''[[Mario Kart Wii]]''.<ref>{{cite|language=en|url=www.nintendo.co.jp/ir/en/finance/software/wii.html|title=IR Information : Sales Data - Top Selling Software Sales Units - Wii Software|publisher=Nintendo|accessdate=June 3, 2024}}</ref> ''New Super Mario Bros. Wii'' received two follow-ups in [[List of games by date#2012|2012]]: ''[[New Super Mario Bros. 2]]'', a direct sequel to ''New Super Mario Bros.'' for the [[Nintendo 3DS]], and ''[[New Super Mario Bros. U]]'', a direct sequel to this game as a launch title for the [[Wii U]].

This is the first of two games released outside of Japan and South Korea to feature a different-colored game box, the second being the [[Wii]] version of ''[[Mario & Sonic at the London 2012 Olympic Games (Wii)|Mario & Sonic at the London 2012 Olympic Games]]''. The box for ''New Super Mario Bros. Wii'' is red, as opposed to most other Wii games with a white box.
==Story==
[[File:NSMBW Prologue.png|thumb|upright=1.1|left|Bowser Jr. and the Koopalings jumping out of the cake]]
[[Mario]], [[Luigi]], [[Yellow Toad and Blue Toad|Yellow Toad, and Blue Toad]] are celebrating [[Princess Peach]]'s birthday, when a big [[cake]] slides in. As Princess Peach approaches it, [[Bowser Jr.]] (who masterminded the plot to infiltrate via the birthday cake<ref>{{cite|url=www.nintendo.co.jp/wii/smnj/story/index.html|publisher=nintendo.co.jp|title=''New Super Mario Bros. Wii'' character page] (Click on the blue circle with the arrow to reach the Koopaling page and click on the pictures to see the short bio of each of the Koopalings)|accessdate=June 3, 2024}}</ref>) and the [[Koopalings]] jump out. The Koopalings throw the cake on top of Princess Peach, the Mario Bros., and the Toads, trapping Princess Peach inside and leaving the Mario Bros. and Toads briefly stunned. From there, the Koopalings and Bowser Jr. run out of the castle and load the cake onto their [[airship]] while the Mario Bros. and the Toads recover and follow closely. The Toads from the castle soon use a [[cannon]] to blast away presents containing Propeller Mushrooms and Penguin Suits so Mario and the others can obtain them, but they explode in the air and spread the items in 9 worlds.<ref>[http://www.true-gaming.net/tgupload/images2/mario3.jpg Famitsu scans]</ref>

Throughout the chase, Mario and co. battle the Koopalings in their fortresses, then in their castles. Afterward, Bowser Jr. flies in the airship with Princess Peach stuck in it, though during two occasions, the airship leaves without Bowser Jr., allowing the Mario Bros. and Toads to chase after him. When the gang defeats Bowser Jr. in World 8, [[Kamek|Magikoopa]] appears and takes Princess Peach away, taking her to [[Bowser's Castle]] and locking her in a cage.

When Mario and the gang finally get to Bowser's Castle, they find [[Bowser]] and battle him. One of them has to [[jump]] on a [[! Switch]] behind Bowser to send him falling into the pit below. After Mario, Luigi, Yellow Toad, and Blue Toad celebrate their "victory", they see "Princess Peach" in a cage, until they realize that it is actually Magikoopa in disguise. Magikoopa then sprinkles magic into the pit Bowser fell in, which turns Bowser [[Giant Bowser|giant]]. After Bowser has been powered up, the four can do nothing but flee from the giant boss. Soon they find a dead end with a huge ! Switch, and the real Princess Peach in a cage above it. They push it, and Bowser falls through the floor as the princess is released from her cage. As Mario and Princess Peach walk out, they see Luigi, Yellow Toad, and Blue Toad arrive in their hot air balloons. Luigi lets Mario and Princess Peach into his balloon but is accidentally left behind, so Yellow Toad and Blue Toad offer Luigi a ride in their balloon. As they sail off, Princess Peach asks Mario if she told him about the [[World 9 (New Super Mario Bros. Wii)|secret world]]. If the player beats the level again, Princess Peach will ask Mario to tell her about his adventure again.

[[File:NSMBW Bowser's Castle Falling Over.png|200px|thumb|left|Bowser, Bowser Jr., and the Koopalings watch as the castle collapses]]
In a post-credits scene, [[Larry|Larry Koopa]] arrives at Bowser's Castle from [[World 1 (New Super Mario Bros. Wii)|World 1]] and is shown exhausted and limping before collapsing onto the ground. Bowser Jr. walks up to him and orders him to get up and help the rest of the Koopalings trying to push Bowser, who is now back to normal size, right side up. They finally succeed and celebrate, but the castle soon falls on top of Bowser before the screen cuts to black and a crushing sound is heard, along with Bowser groaning in pain.

==Gameplay==
[[File:NSMBW Multiplayer.png|thumb|left|[[World 2-1 (New Super Mario Bros. Wii)|World 2-1]] being played by four players]]
The gameplay of the game is mostly based on its DS predecessor. The story mode of the game can be played in either single-player mode or multiplayer cooperative mode. Players can be freely added and removed in between levels on the world map. The camera pans as players move, and it zooms in and out depending on their distance to one another. However, there is a limit, and players who are far behind lose a life.

After players clear [[World 1-3 (New Super Mario Bros. Wii)|World 1-3]] for the first time, a Toad runs up and tells the heroes that Bowser Jr. ordered his minions to stuff Toads they capture into [[? Block]]s. If the level was cleared in single-player mode, a [[Goomba]] then appears and carries the Toad to a ? Block in [[World 1-1 (New Super Mario Bros. Wii)|World 1-1]], where the player must carry him to the goal. Toads can be rescued only in single-player mode.

When a player loses a life in multiplayer, they reappear inside a [[bubble]]. The player inside the bubble can shake the [[Wii#Wii Remote|Wii Remote]] to bring themselves closer to the other players that are currently not in a bubble. Bubbles can burst only when a player not in a bubble comes in contact with the bubble or throws a [[fireball]], [[Ice Ball|ice ball]], shell, or frozen enemy at the bubble. A player can place themselves in a bubble purposefully without losing a life by pressing the {{button|wii|A}} button on the Wii Remote or the {{button|wii|C}} button on the Nunchuk if it is connected. The player inside the bubble cannot be harmed by anything and retains their previous form. However, if everyone has lost all their lives, or if someone loses a life and everyone else is in a bubble, then all players have to restart the level from the beginning or the [[Checkpoint Flag|midway point]] if the players touched it on a prior attempt. The players in bubbles return to their [[Small Mario|normal forms]] but do not lose any lives.

When one player grabs the [[Goal Pole|pole]] at the end of the level, the [[Time Limit|timer]] stops and the other players would have three seconds to grab the pole before the level ends. If they do not make it in time, the level still ends; however, there is no penalty to the players left behind other than the lost opportunity for [[point]]s or a [[extra life|1-Up]] by grabbing the pole.

[[File:NSMBW World 6-6 Screenshot.png|thumb|left|The light on the boat's direction being changed by tilting the Wii Remote]]
Players play the game by holding the Wii Remote sideways or by using the Wii Remote and Nunchuk combination. If a player tilts the Wii Remote, certain actions can be performed, such as changing the direction of a light or tilting special platforms when they have been activated. Players can activate these by standing on them; the color and the symbol of the character on the platform determine who is controlling them.

Shaking the Wii Remote activates the [[Spin Jump]], as seen in ''[[Super Mario World]]''. Players can carry objects such as frozen enemies and barrels by {{button|wii|1}} ({{button|wii|B}} with the Nunchuk) and shaking the Wii Remote near the object.

It is possible to ride on [[Yoshi (species)|Yoshi]] as well. In addition to his usual ability to consume most enemies, he can retain many different objects in the game in his mouth, including [[hammer]]s, fireballs, ice balls, shells, Toads, power-ups, and other players. Yoshi can also use his [[Flutter Jump]], a move first introduced in ''[[Super Mario World 2: Yoshi's Island]]''. Similar to in ''[[Super Mario World]]'', Yoshi can eat five [[apple]]s in a course to produce an [[Yoshi's Egg|egg]] with a power-up or 1-Up. Yoshi cannot be harmed by sharp objects and enemies such as [[Spiny|Spinies]] and [[Piranha Plant]]s as long as he lands on them. Yoshi(s) brought to the end of the course must be abandoned, and therefore there are only certain levels in which players can ride Yoshis.

[[File:NSMBW World 7-2 Screenshot.png|thumb|Mario can swim in these [[Water Ball]]s.]]
[[Enemy Course]]s return from ''[[Super Mario Bros. 3]]'', as well as [[Toad House]]s; items obtained are stored in an inventory that can be accessed with the {{button|wii|1}} button ({{button|wii|B}} button with the Nunchuk) on the map screen. Unlike in ''New Super Mario Bros.'' and ''Super Mario World'', there is no spare item box, so players cannot activate items during levels. Pressing {{button|wii|-}} on the map allows the player to go to any previously visited world.

Up to five stars can appear on a player's profile. The first appears after the player has beaten [[Bowser]] for the first time (using any method), the second appears when all levels in the first eight worlds (except [[Warp Cannon]]s/[[Warp Pipe|Pipes]] and Toad Houses) have been beaten, the third appears if all [[Star Coin]]s from Worlds 1 to 8 are obtained, the fourth appears when all Star Coins in World 9 have been obtained, and the fifth appears once the player has beaten every level (including Warp Cannons, etc.) and has collected every Star Coin. The stars shine if the [[Super Guide]] block did not appear at all during the game, even if it is not used when it appears.
===Super Guide===
{{main|Super Guide}}
[[File:NSMBW World 6-3 Super Guide.png|thumb|upright=1.1|The Super Guide mode of [[World 6-3 (New Super Mario Bros. Wii)|World 6-3]] in action]]
Debuting in this game, the Super Guide provides players assistance to clear levels. When the player has failed to pass a level at least eight times in single player, a green box appears at the start of the level or at the [[Checkpoint Flag|midway point]]. When the player hits the green box, the level restarts in autopilot mode: A computer-controlled [[Luigi]] plays the level on his own. The Super Guide only shows the player how to beat the level, but it does not use shortcuts, nor reveals secrets. While the Super Guide is running, the player can press the {{button|wii|+}} button on the Wii Remote at any time to take control back; the game starts exactly where the Super Guide left off. Once the player has taken control back, they cannot turn it back on during the remainder of the level. Even when the Super Guide assistance is used, the level is still considered complete, though it is now marked red, and the stars on the save file no longer shine. If the player takes over, they continue to play as Luigi rather than Mario. Losing a life as Luigi allows the player to control Mario again, without losing a life.
{{br}}

===Free-for-all===
[[File:Free-for-all NSMBW.png|thumb|upright=1.1|]]
'''Free-for-all''' is a multiplayer-only mode that is selectable from the game's main menu. Every course from the main game is selectable in this mode, although the worlds have to be beaten once in the main game in order to play them in Free-for-all. This mode is very similar to the main game, but there are no midway points, and on the end of a level, the number of points each character got is seen. However, unlike in [[Coin Battle]], the character does not say a "happy" phrase after winning, and the number of times each player won is also not seen. Additionally, if all of the players manage to get to the [[Goal Pole|pole]], the level is marked on the level-selection menu with a gold frame, and the words "TEAM FINISH!" is seen for about a second. If not all players manage to reach the pole, it is marked with a silver frame and the word "CLEAR!" is seen instead.

===Controls===
When playing on a [[Wii]] or [[Wii U]], the game requires a [[Wii Remote]] by itself horizontally or attached to the [[Nunchuk]]. The controller for the {{wp|Nvidia Shield TV}} has a more conventional layout and lacks the same motion-sensing capabilities of the Wii Remote. To compensate, actions that originally involved shaking the Wii Remote are performed by pressing the trigger or bumper buttons.

===Overview===
[[File:NSMBW Adddrop.png|200px|thumb|left|Players being added into the game are allowed to choose their own characters. Mario lacks a cap because he has 99 lives, the maximum amount of lives in the game; this is an [[Easter egg]].]]
[[File:NSMBW World 1 World Select.png|thumb|upright=1.4|The world-selection map with all worlds unlocked]]
The game has nine worlds with a world map similar to the one in ''New Super Mario Bros.'' There still are [[Toad House]]s, [[tower]]s, [[castle]]s, Warp Cannons, Warp Pipes (in World 2 and World 6), [[vine]]s (in World 7), and horizontal "platform" Pipes (in World 6). Enemies also patrol the map screen. If the enemies come in contact with players, they must play an [[Enemy Course]]. Players must collect eight [[Toad balloon]]s to make a chest with a [[Toad (species)|Toad]] trapped in it appear. If the Toad is saved, the players are rewarded with three [[Super Mushroom]]s. Each Enemy Course is different in each world. The layout of the worlds (either horizontally or vertically) alternates among the worlds, with the odd-numbered worlds, Worlds 1, 3, 5, and 7, all going in a horizontal left-to-right direction, and the even-numbered worlds, Worlds 2, 4, 6, and 8, all going in a vertical down-to-up direction.

There are 77 courses in the main game, 14 of which have secret exits, bringing the total number of exits to 91. Captured Toads are sometimes hidden in previously beaten levels in single-player mode. If the Toad is carried to the level exit without being damaged, Mario is rewarded with three 1-Ups. However, only one 1-Up is rewarded to Mario if the Toad took damage before reaching the goal. Additionally, when Toad is saved, the "Course Clear" theme from ''Super Mario Bros.'' is played instead of the normal one, fireworks go off, and a Toad House opens at the starting point of the world. The type of house that appears depends on the last digit in the level timer when Toad and/or Mario touch(es) the pole. If the Toad is damaged twice, it is defeated, and Mario cannot bring it to the goal anymore.

Captured Toads appear only in the following levels:

Other than the game's main campaign, which can be played with up to four players, ''New Super Mario Bros. Wii'' offers special multiplayer challenges. Those challenges have some levels taken from the campaign and some newly created levels. There is a Free for All mode and a [[Coin Battle]] mode. The Free for All mode has players competing for a high score, while the Coin Battle mode has them competing for the most collected [[coin]]s in the level.

World 9 is unlocked after completing the game. There are eight stages in that world, and each stage is unlocked by collecting all the [[Star Coin]]s in each of the preceding eight worlds.

Wii|url=nintendo.com/jp/character/mario/en/history/new_smb_wii/index.html|publisher=Mario Portal Game Archive|date=2023|accessdate=14 Aug. 2024}}</ref> The default order they are listed derives from their occurrence in-game with adjustments to ensure enemies are listed next to their immediate relatives. The Mega Deep-Cheep is lumped with its smaller counterpart in both sources, but it is recognized as distinct in the original ''New Super Mario Bros.'' and this is followed suit here.

The displayed English names appear in the [[Prima Games]] guidebook,<ref>{{cite|author=Bueno, Fernando|title=''New Super Mario Bros.

Two localization choices made are deviated from here: Sledge Bros are referred to as "Sumo Bros." in the guidebook<ref>Bueno, p. 14</ref> and on their [[:File:NSMBWiiTC-24-Back.png|trading card]], but that name was previously and subsequently used for a [[Sumo Bro|different enemy]]. Mechakoopas are referred to as "Windup Koopas" in the guidebook,<ref>Bueno, p. 16</ref> but are recognized under their original name on their [[:File:NSMBWiiTC-17-Back.png|trading card]] and this is followed in paratexts for subsequent games. Several enemies wholly new to the franchise did not have names published at the time of the game's release and are incorporated here in retrospect. These are Hefty Goomba, Eep Cheep, Scaredy Rat, and Big Fuzzy.

==Staff==
{{main|List of New Super Mario Bros. Wii staff}}
[[Nintendo Entertainment Analysis and Development]] developed the game, with the director being Shigeyuki Asuke and the producers being Takashi Tezuka and Hiroyuki Kimura.

==Development==
As demonstrated by development information for various games, [[Shigeru Miyamoto]] had been struggling to add simultaneous multiplayer to ''[[Super Mario (franchise)|Super Mario]]'' games for a long time. He tried to experiment with multiplayer aspects at the start of most of his ''Super Mario'' projects, as can be seen in pre-release screenshots of games such as ''[[Super Mario 64 DS]]'' and ''[[New Super Mario Bros.]]'': different multiplayer aspects were evidently intended for both of those games during early stages of development. When the experiments with multiplayer failed to come to fruition, in part due to technical limitations, the developers refocused on what they were used to, single-player; for both of the aforementioned games, multiplayer was put on the back-burner and was only used in in-engine side modes and unrelated [[minigame]]s. The Wii's hardware allowed Miyamoto to ensure that the game could process all loaded items and enemies at once, and have the camera focus on all players.<ref>{{cite|author=Klepek, Patrick|date=June 2, 2009|title=''New Super Mario Bros.'' Achieves Shigeru Miyamoto's Dream: Multiplayer|publisher=G4TV|deadlink=y|archive=web.archive.org/web/20141012214116/http://www.g4tv.com/thefeed/blog/post/696129/new-super-mario-bros-achieves-shigeru-miyamotos-dream-multiplayer|accessdate=June 3, 2024}}</ref>

''New Super Mario Bros. Wii'' was developed as the flagship title for [[Super Guide]]. This feature first surfaced as a June 30, 2008 patent for a "Kind Code" with three demo play modes: Game, in which, when the player gets stuck during standard gameplay, they can view a walkthrough video that appears in the screen's top right corner; Digest, in which the player watches developer gameplay and can join the game at a particular point, but cannot save; and Scene Menu, in which players go directly to specific parts of the game without loading their games or watching the digest.<ref>{{cite|author=Crecente, Brian|date=January 9, 2009|url=kotaku.com/nintendo-patent-reveals-potential-paradigm-shift-in-des-5127251|title=Nintendo Patent Reveals Potential Paradigm Shift in Design|publisher=Kotaku|accessdate=June 3, 2024}}</ref> Super Guide uses the Digest mode, and [[hint movies]] appear to use the Scene Menu mode.

In a 2010 interview with ''[[Nintendo Power]]'', director Shigeyuki Asuke discussed several aspects of the game's development.<ref>{{cite|date=April 2010|title=''[[Nintendo Power]]'' volume 253|page=71-73|publisher=Nintendo of America|language=en-us}}</ref> The development team considered adding vehicles which allowed the player to move freely and objects that were controlled by tilting the Wii Remote. These ideas were simplified so that they were more easily understood and better complement the core gameplay, leading to the creation of the [[Propeller Mushroom]] and [[Penguin Suit]]. In regards to the final battle with [[Bowser]], the developers wanted to make it really feel like a final boss by making Bowser huge, giving him the ability to break through walls, and making a [[! Switch|switch]] that collapses the floor under him the only way of defeating him. A static arena could not facilitate this battle, so it was turned into a platforming stage. The textures of Bowser's eyes and hair were also changed to add to the effect. [[World 9 (New Super Mario Bros. Wii)|World 9]] was designed to challenge players who have conquered the rest of the levels while still being fun to play. The [[Midair Spin]] was added to make use of the Wii Remote's features. The [[Koopalings]] and [[Airship]]s were added because of their nostalgic value and they act as distinct set pieces. The inclusion of [[Yoshi (species)|Yoshis]] was decided early in development with Asuke imagining players fighting over one Yoshi. However, Yoshis greatly change the way levels are played, so they are limited to a few levels. Yoshis were added to levels if they made the levels more fun to play.

==Pre-release and unused content==
[[File:NSMBW Prerelease Moving Platforms.png|thumb|An early version of World 7-4]]
{{main|List of New Super Mario Bros. Wii pre-release and unused content}}
During development, Princess Peach was planned to be a playable character. This idea was scrapped because the Toads better suited Mario's stature and the need for special programming to handle the physics of the dress. The development team wanted the game opening sequence to be more dramatic, causing a dispute between them and Shigeru Miyamoto.

In the game's E3 2009 trailer, it shows an early design of the motion-controlled platforms in [[World 7-4 (New Super Mario Bros. Wii)|World 7-4]]. They lack they indicator which shows the player in control of the platforms and do not make a sound when they travel on the tracks. The bottom of the platforms are also less round compared to the final design. The tracks feature a simpler design, being completely black with red endpoints instead.

==Glitches==
{{main|List of New Super Mario Bros. Wii glitches}}
===Infinite Coins===
[[File:NSMBW Infinite Coins Glitch.png|thumb|The frozen Climbing Koopa dropping coins]]
The player needs an Ice Flower in {{world link|4|castle|World 4-Castle (New Super Mario Bros. Wii)}} and get to the place with the large [[Flip Panel (Chain-Link)|flip panel]] with a [[Climbing Koopa]] on it. Mario must stand on the front side, then jump to throw an [[Ice Ball]] at the Climbing Koopa. The player must hold the [[Chain-Link|fence]] again and spin the flip panel as fast as possible. The Climbing Koopa freezes, falls to the ground and drops infinite [[coin]]s.

===Infinite lives===
[[File:NSMBWii Best Glitch Ever.png|thumb|left|Four players accruing lives in World 1-3]]
At least two players must enter a course containing both [[Yoshi (species)|Yoshi]]s and [[Koopa Troopa]]s that allows the player(s) wishing to perform the glitch to equip a [[Propeller Mushroom]]; these courses are [[World 1-3 (New Super Mario Bros. Wii)|World 1-3]], [[World 2-5 (New Super Mario Bros. Wii)|World 2-5]], [[World 3-2 (New Super Mario Bros. Wii)|World 3-2]], and [[World 6-4 (New Super Mario Bros. Wii)|World 6-4]]. After using a Yoshi to eat a Koopa Troopa, a [[Synchro Ground-Pound|Simultaneous Ground Pound]] must be performed, causing the Koopa Troopa within the Yoshi's mouth to enter an "invulnerable" state. Its shell can then be spat out and held while performing a [[Drill Spin]], accruing enough lives to max out the life meter in seconds while only using a few Drill Spins.

==Notable promotions==
===Trading cards===
[[File:TCG EP SMB box.jpg|thumb|A box set of the trading cards]]
{{main|List of New Super Mario Bros. Wii trading cards}}
Trading cards were released to promote the game's release. They feature various characters, enemies, items, and levels from the game. Each booster pack contains four regular cards and one each of Tips & Tricks, Standee, Foil, and [[FunTats]].

===Piano book===
A book published by {{wp|Alfred Music|Alfred Music Publishing}} titled ''[[New Super Mario Bros. Wii: Simplified Piano Solos]]'' was released, containing sheet music for seventeen songs from the game.

===Arcade adaptation===
A Japan only arcade game developed by [[Capcom]] was released in 2011 called ''[[New Super Mario Bros. Wii Coin World]]''.

==Reception==
The former Mario and Luigi voice actor, [[Charles Martinet]] originally stated that this game is his favorite ''Super Mario'' game of all time. His new favorite ''Super Mario'' game is ''[[Super Mario Maker]]''.

[[File:NSMBW Kamek Using Magic.png|thumb|Magikoopa using magic to assist Roy]]
*''[[Donkey Kong (game)|Donkey Kong]]'': [[Broozer]]s hit [[barrel]]s when a player is near, rolling the barrel towards them, similar to [[Donkey Kong]]'s ability to throw barrels in this game.
*''[[Mario Bros. (game)|Mario Bros.]]'': The [[POW Block]] reappears and has the same design as in ''Mario Bros.'' The POW Block can also be carried. The first underground Coin Battle area in {{world link|coin|1|World Coin-1 (New Super Mario Bros. Wii)}} also bears some resemblance to the ''Mario Bros.'' arena.
*''[[Super Mario Bros.]]'': The secret "Level Clear" tune and fireworks are taken from this game. The first tunes from the overworld theme is played during the beginning of the Staff Roll. The overworld theme is once again used as a cover for the Toad Houses. The underground theme is used as a cover for the volcano underground theme. The ending fanfare is covered when [[Kamek|Magikoopa]] and [[Princess Peach]] are rescued in addition to when Mario and Princess Peach leave [[Bowser's Castle]]. Near the beginning of the game, [[Bowser Jr.]] states in a letter that he ordered his minions to stuff every [[Toad (species)|Toad]] they see into a [[? Block]], which might be a reference to the fact that [[Bowser]] transformed them into ? Blocks, according to the instruction book. Also, [[Roy|Roy Koopa]]'s Castle has three way corridors, with only one being the correct path. This puzzle mimics the puzzles in World 4-4, World 7-4, and World 8-4. {{world link|coin|2|World Coin-2 (New Super Mario Bros. Wii)}} is nearly identical in layout to [[World 1-1 (Super Mario Bros.)|World 1-1]] from this game. The secret corridor found above the ceiling near the end of [[World 1-2 (New Super Mario Bros. Wii)|World 1-2]] is reminiscent of the empty corridor found above the ceiling in [[World 1-2 (Super Mario Bros.)|World 1-2]].
*''[[Super Mario Bros.: The Lost Levels]]'': World 2-4 features [[wind]]. The extended version of the ending fanfare can be heard exclusively when Bowser is defeated in multiplayer.
*''[[Super Mario Bros. 2]]'': Grabbable objects, such as the POW Block, are typically held above the head, like in this game.
*''[[Super Mario Bros. 3]]'': The [[Penguin Suit]] is based on the suits in this game, mainly the [[Frog Suit]]. The [[Koopalings]]' battle theme is a cover and once again played when fighting against them. The Airship theme is a cover that plays on the Airships. The design of the [[fortress]]es is based on the fortress sprite from this game. [[Jellybeam]]s resemble the in-game sprites of [[Jelectro]]s. [[Stalking Piranha Plant]]s resemble [[Ptooie]]s whose behavior is largely given to [[River Piranha Plant]]s. The [[Enemy Course]]s are similar to the levels when fighting against a [[Hammer Bro]], [[Fire Bro]], [[Boomerang Bro]], or [[Sledge Bro]] and even use a cover of the song. Also, reserved power-ups can be used on the world maps. The game features an inventory window, rather than a summonable item, only accessible from the overworld, reminiscent of that of ''Super Mario Bros. 3''. Most of the Koopalings are fought in the same kind of land they are, like in ''Super Mario Bros. 3''. For example, Lemmy Koopa is in charge of the ice-themed world in both games, and Wendy O. Koopa is in charge of the water-themed world in both games. In addition, [[Power-up Panels]] is likely based on the card-matching minigame in this game. [[Toad House]]s, as well as fortresses and [[castle]]s as seen on the world map, feature checkered floor tiles like those seen in this game's fortress and kings' chambers. Artwork of Mario holding a [[Green Shell]] resembles [[:File:RaccoonMario GreenShell SMB3.png|promotional artwork]] of [[Raccoon Mario]] holding a [[Koopa Troopa|Green Koopa Troopa]] from this game. Artwork of a [[Spike]] throwing a [[Spike Ball|spiked ball]] resembles [[:File:SMB3 Spike.jpg|its promotional artwork from this game]].
*[[Super Nintendo Entertainment System]]: On the cover of the game disc (the side opposite with the part that reads the console), Mario, Luigi, Blue Toad, and Yellow Toad are positioned in the same way that the buttons on the European and Japanese SNES controller are.
*''[[Super Mario World]]'': ''New Super Mario Bros. Wii'' is the first game in the 2D ''Super Mario'' series to use this game's variant of the power-down sound while still keeping the original ''Super Mario Bros.'' sound effect for entering and exiting pipes, as well as the first to use a [[Coin]] sound effect similar to this game's. The design on the Fortress doors leading to the [[List of bosses|boss]] is similar. Yoshis reappear, along with the sound heard when mounting onto Yoshi and the drumbeat that is added to the music, similar to this game. Parts of the castle BGM can be heard in the castle levels. The sound effect that plays when the invincibility wears off is taken from the [[P Switch|Switch Block]] when the activation is going to stop, as well as the sound that plays when the [[Super Star]] power-up runs out. The [[World 9 (New Super Mario Bros. Wii)|World 9]] is similar to the [[Star World]] and the [[Special Zone]]. Also, World 3 has a switch that activates blocks, similar to the [[Switch Palace]]s in this game, without having to go through a level. Almost the entirety of {{world link|7|castle|World 7-Castle (New Super Mario Bros. Wii)}} can be skipped by finding the secret exit in {{world link|7|tower|World 7-Tower (New Super Mario Bros. Wii)}} and completing [[World 7-6 (New Super Mario Bros. Wii)|World 7-6]], like how the [[Back Door]] can be accessed by finding the secret exit in [[Valley of Bowser 2]] and completing [[Valley Fortress]]. The [[Koopa Clown Car]] returns. World 4-Castle, whose boss is Wendy O. Koopa, features Skewers, much like [[6 Wendy's Castle|#6 Wendy's Castle]]. [[River Piranha Plant]]s resemble [[Jumping Piranha Plant]]s. [[Jumbo Ray]]s don goggles resembling those of [[Blurp]]s and [[Dolphin]]s. [[King Bill]]s are shortened in length like the [[Bomber Bill|Banzai Bill]]s from this game. Some members of [[Boo Buddies|Circling Boo Buddies]] make the same facial expressions as [[Boo]]s in this game. Boos also circle around [[Ghost House]]s like in this game. Artwork of Mario jumping with a [[Yoshi (species)|Green Yoshi]] resembles this game's box art. Artwork of [[Blue Toad (character)|Blue Toad]] riding a [[Yoshi (species)|Pink Yoshi]] resembles [[:File:SMW Art - Yoshi and Berry.png|promotional artwork]] of [[Yoshi]] eating a [[Fruit (Yoshi food)|berry]] from this game. Artwork of Bowser resembles [[:File:BowserSMW1.png|his promotional artwork from this game]].
*''[[Donkey Kong Country]]'': The animal buddy mechanics used in this game, are used on the Yoshis; players can only use Yoshi in certain levels, and they ditch him after clearing the level.
*''[[Super Mario World 2: Yoshi's Island]]'': Just before the main boss of the world, [[Kamek]] appears and flies all over the room, using his magic on the room and boss. Fake walls reappear. The room Kamek's battle takes place in is similar to the final room of [[King Bowser's Castle (Super Mario World 2: Yoshi's Island)|King Bowser's Castle]], containing autoscrolling blocks that can be transformed by {{conjectural|Magic spell}}s. Kamek turns Bowser into a giant for the final battle. [[Bubble]]s reappear to protect players from harm, as they did for [[Baby Mario]]. The dark also makes a reappearance in several levels. The introduction to the castle boss theme is a shortened cover of the introduction to the boss theme from this game. [[Bowser Jr.]]'s final battle involves a floor that can be [[Ground Pound]]ed to produce shockwaves, like the floor involved in [[Baby Bowser]]'s initial fight. [[Giant Goomba]]s and [[Hefty Goomba]]s split into their immediately smaller counterparts like [[Milde]]s.
*''[[Super Mario 64]]'': "Inside the Castle Walls" is played inside [[Peach's Castle]]. Also, after losing to the Power-up Panels mini-game (by matching two-of-a-kind Bowser or Bowser Jr. cards), a short arrangement of "[[Bowser's Theme]]" and the tune that plays when attempting to enter a locked door is heard. In the same vein, winning a Toad House mini-game plays an arrangement of the course clear fanfare. The fanfares for clearing a tower, castle, or airship are rearrangements of the "Koopa Clear" fanfare. When the player goes into a [[Warp Cannon]] or aims a [[cannon]] in [[1-up Blast]], cannon sounds from this game are heard. In both games, [[Chain Chomp]]s are freed by [[Ground Pound]]ing their posts three times. One Chain Chomp in [[World 7-2 (New Super Mario Bros. Wii)|World 7-2]] may be freed to destroy a [[Brick Block|brick]] wall and uncover a [[Star Coin]], which is reminiscent of how the Chain Chomp in [[Bob-omb Battlefield]] must be freed to uncover a jailed [[Power Star]].
*''[[Mario Kart 64]]'': About 30 seconds in the [[World 9 (New Super Mario Bros. Wii)|Rainbow Path]], a cover from the [[N64 Rainbow Road|Rainbow Road]] theme can be heard.
*''[[Super Mario Sunshine]]'': When [[Iggy]] is hit during his second battle, the [[Big Chain Chomp]] pulling his carriage becomes enraged and glows red like the [[Chain Chomp]] in Pianta Village.
*''[[Mario Party 7]]'': Luigi's artwork on the back of the Japanese cover art next to the Super Guide description is based on one of his artwork from this game.
*''[[New Super Mario Bros.]]'': ''New Super Mario Bros. Wii'' is a follow-up to this game. Most of the songs are covers of songs from this game, such as the overworld theme (and subsequently the snow theme), course clear theme, athletic theme, P Switch theme, tower and castle boss clear themes (and subsequently the airship clear theme), and multiplayer results theme. The introduction to the [[airship]] boss theme is a rendition of the introduction to [[Bowser Jr.]]'s battle theme from this game. The melody that plays during the intros to both games' desert themes are the same. A portion of the melody that plays 22 seconds into this game's volcano theme is reused in the outside volcano theme. The tower themes in both games are very similar. Certain renditions of older tracks in this game, like the underground theme from ''[[Super Mario Bros.]]'' are covered. The [[Mini Mushroom]] returns. Carrying objects underwater gives the player enhanced swimming speed while also restricting them to the surface, like in this game. Some text in ''New Super Mario Bros. Wii''{{'}}s instruction manual is reused from its instruction manual (for example, the "Blunders and Game Over" section in ''New Super Mario Bros.''{{'}}s manual is reused in ''New Super Mario Bros. Wii''{{'}}s manual, except the word "whacked" is replaced with "clobbered"). Various pieces of promotional artwork are reused as are all eight world themes from this game. Vibrant-purple [[poison (obstacle)|poison]] returns in forest levels. Unlike other mushrooms in ''New Super Mario Bros. Wii'', the mushrooms seen on the world map of the [[World 5 (New Super Mario Bros. Wii)|Jungle World]] are colored like the [[Mushroom Platform]]s of this game. The broken fragments of [[? Block]]s, [[Brick Block]]s, and [[Empty Block]]s and the unused broken fragments of [[Hard Block]]s and [[Red Block]]s use the designs of their respective blocks from this game, though they appear distinct from this game's own block fragments.
*''[[Yoshi's Island DS]]'': Kamek turns Bowser into a giant for the final battle.
*''[[Super Mario Galaxy]]'': During the Staff Roll, an outtake of a Princess Peach voiceover states that she will wait for [[Mario]] at the night of the [[Star Festival]], but she is interrupted by Bowser. The 1-up sound effect from this game plays when the player gets a 1-up in ''New Super Mario Bros. Wii'', but only from the speakers of the Wii Remote. In [[World 9 (New Super Mario Bros. Wii)|World 9]], multicolor star-shaped objects fall from the sky, like [[Star Bit]]s. The [[Ice Flower]] returns from this game, but has a different function (in ''Super Mario Galaxy'', Ice Mario can walk on liquid and in ''New Super Mario Bros. Wii'', he can throw ice balls). The [[Midair Spin]], a move similar to the [[Spin]], is introduced. [[Clampy]]s make a reappearance.
*''[[Mario Kart Wii]]'': The character's icons are reused in the character selection screen.

==References in later media==
[[File:MP9 Toad Road Scene Artwork.jpg|thumb|Toad Road from ''Mario Party 9'' shares visual cues with this game.]]
*''[[Super Mario Galaxy 2]]'': The [[Checkpoint Flag]] appears in this game and it plays a similar role. The Cosmic Guide and the [[Tip Network]] are similar to the Super Guide and to the videos of the [[Peach's Castle]]. The function of the world maps are similar to those from this game.
*[[Nintendo 3DS]]: This game's box artwork was used for the [[Nintendo 3DS]] demo at E3 2010.<ref>{{cite|author=Nintendo Fuser|date=June 15, 2010|url=www.youtube.com/watch?v=GYnyBxVhK_c|title=Nintendo 3DS - First Hands On|language=en|publisher=YouTube|accessdate=June 3, 2024}}</ref>
*''[[Donkey Kong Country Returns]]'': [[Super Kong]] is the equivalent of the Super Guide. During 2 Player mode, if either Donkey Kong or Diddy Kong lose a life and the other one is still alive, the Kong that was defeated floats back inside a [[DK Barrel]] hanging from a balloon, similar to the [[bubble]] system in this game.
*''[[New Super Mario Bros. Mii]]'': A very similar trial based on ''New Super Mario Bros. Wii''.
