Mario and Luigi, the Mario Brothers, must try to get rid of Shellcreepers (turtles), Sidesteppers (crabs, which need to be hit twice), and Fighterflies (flies, which can be defeated only while they touch the platform) that come [[JustForPun pouring out of the waterworks]]. Hit the floor beneath them to flip them over, then kick them into the water. Collect coins for bonus.

Later, the [[AnIcePerson Slipice]] (renamed Freezies in the NES version) will come out and freeze the platforms, making your traction very poor. As the game progresses, water drops hang below the platforms and freeze into deadly icicles, which fall soon after. [[note]]This doesn't happen in the NES version, though.[[/note]]

Keep track of the green fireballs as they will appear more frequently. The red fireball can also be a menace. If need be, you can hit the fireballs from below when they touch the platform. Beware of hitting the red fireball. It rapidly reappears and [[RedOnesGoFaster moves much faster]].

Hit the POW platform to knock over your enemies and destroy fireballs. Be wise, because you only get three, and it doesn't come back until after the bonus round. Each difficulty level begins with three [=POWs=] and a [[BonusLevel bonus wave]] in which 10 coins are available to be collected.

Released in arcades in 1983 and later ported to home consoles, the game introduced many elements used in later Mario games, like turtles, pipes, collecting coins, and Mario's brother Luigi.

!!Tropes:
* AttractMode: The original arcade game has one, which, alongside the tutorial, gives the player a quick crash course on how to play the game.
* BonusLevel: One where the only goal was to collect all the coins before time ran out.
* CharacterTitle: Refers to the player one character in the the red shirt and hat, and blue overalls[[note]]"Bros." refers to there being two characters[[/note]].
* ChuckCunninghamSyndrome: Alas, poor Shellcreeper. In all remakes of this game except for the ''VideoGame/SuperSmashBros Brawl'' level, Shellcreepers are replaced with Spinies. {{Justified|Trope}}; being turtles, Shellcreepers were the predecessors of the later Koopa Troopas, which are nigh-identical to Shellcreepers, and that would cause confusion.
* EarlyInstallmentWeirdness: No GoombaStomp, and the turtles kill you when you try to jump on them. There's also no Princess Peach, Bowser, or the Mushroom Kingdom. Just two plumbers dealing with creatures in a sewer.
* EmbeddedPrecursor: This game is playable in all the ''Super Mario Advance'' games [[note]](remakes of ''VideoGame/SuperMarioBros2'', ''VideoGame/SuperMarioWorld'', ''VideoGame/YoshisIsland'' and ''VideoGame/SuperMarioBros3'')[[/note]] as well as in ''VideoGame/MarioAndLuigiSuperstarSaga'', and in ''VideoGame/SuperMario3DWorld'' as a slightly reworked version called ''[[https://www.youtube.com/watch?v=Ds0X4QkfeC4 Luigi Bros.]]''.
* EndlessGame: As with most [[UsefulNotes/TheGoldenAgeOfVideoGames golden age]] games.
* FlippingHelpless: Mario and Luigi could flip turtles (Shellcreepers) over by jumping up from directly below and hitting the level the turtle was walking on. If neither Mario nor Luigi ran into the turtle and knocked it off, it would eventually jump out of its shell, kick the shell over, get back in and continue walking. This could be done with crabs (Sidesteppers) as well, but required two hits.
* GiantEnemyCrab: The Sidesteppers. You even have to flip them over, on their backs.
* HyperDestructiveBouncingBall: Both fireballs. THe green one bounces from one side of the screen to the other. The red one, which bounces of the ceiling and walls especially applies if you stay in a level too long.
* IHaveManyNames:
** The Slipice and Sidesteppers were later renamed Freezies and [[ShapedLikeItself Crabs]].
** Shellcreepers were renamed Koopa Troopas. [[note]]Or they're two different sets of characters, depending on whom you ask.[[/note]]
** Inverted with Fighterflies, who are called by that name in the ''VideoGame/MarioAndLuigi'' {{Role Playing Game}}s. There are even a variant called "Superflies".
* InstructiveLevelDesign: The GBA remakes first level is an effective crash course on the games mechanics and is slightly better at tipping off the player on the games mechanics [[ShowDontTell through visual clues]] than the original arcade game, which is good since it lacks the tutorial screen. The Shellcreepers are replaced by Spinies as your common foe, so the player will be tipped off that unlike other Mario games, they can't attack enemies by jumping on them, forcing the player to find an alternative. Jumping around (or bumping the POW block) will quickly reveal that Mario can interact with the floor above him, leading the player to discovering they can flip enemies over by hitting the floor from below. Once the Spinies are made vulnerable, the player will assume you can jump on them now, but it leads to them finding out you kick them offscreen instead.
* JustifiedTutorial: The arcade game has a quick tutorial on starting up, since a new player might be confused about how to attack enemies. The ports and even the GBA remake ditch it, though.
* JumpPhysics: Partly averted in the original game, since it lacked the ability to change direction in midair. The Japan-exclusive update ''Kaetta Kita Mario Bros.'' introduced this in order to bring it in line with the ''SMB'' series, and every other UpdatedRerelease has kept this as part of the game.
%%* MultiMookMelee
* PublicDomainSoundtrack: The game is famous for opening with ''[[Creator/WolfgangAmadeusMozart Eine Kleine Nachtmusik]]''.
* ScoringPoints: This was the last Mario game whose primary goal was to score as many points as possible. Future games, starting with ''VideoGame/SuperMarioBros1'', would follow the "campaign" model.
* StealthPun: In this game, you have to clear each stage by flipping the enemies onto their backs and then "kicking" them while they're "down". Think about that for a second...
* ShoutOut: The commercial for the "Atari" versions of the game uses a jingle set to the tune of the classic sitcom ''Series/Car54WhereAreYou''.
* SmartBomb: The POW Block, which flips over, or otherwise affects all enemies and objects on the ground
* TremorTrampoline: The POW Block works by bouncing the entire stage each time it's hit, which potentially flips enemies over so you can knock them away. As a result, it does not work on enemies currently in the air, especially Fighterflies. In two-player mode, it also makes the other player bounce up slightly.
* VideoGameRemake: The UsefulNotes/GameBoyAdvance version. Most of it is based on the [[NoExportForYou Famicom Disk System version, ''Kaettekita Mario Bros.'']][[note]]"Return of Mario Bros.", or alternately "Mario Bros. Returns"[[/note]], which is slightly closer to the original arcade version, but allows you to change directions while jumping.[[note]] A feature from post-''VideoGame/SuperMarioBros1'' games.[[/note]] It also uses ''VideoGame/SuperMarioBros2''[='=]s sprites for the player characters, even allowing the use of the charged jump. Most people mainly remember this game due to it being released on all ''Super Mario Advance'' games and ''VideoGame/MarioAndLuigiSuperstarSaga''.
* WrapAround: Like a number of arcade games at the time, this game lets you keep going in one direction, appearing offscreen, then appearing at the opposite side.
