''Can you kick off all the pests?''

'''For the page about the series as a whole, see ''Franchise/SuperMarioBros'' Or were you looking specifically for the ''VideoGame/SuperMarioBros1'' game?'''

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 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:
* BonusLevel[=/=]TimedMission: One where the only goal was to collect all the coins before time ran out.
* CharacterTitle
* 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.
-->"Why did that Koopa kill me even though I stepped on its head!?!"
* EarlyInstallmentWeirdness: No GoombaStomp, and the turtles kill you when you try to jump on them.
* 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 [[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. [[HilariousInHindsight You even have to flip them over, on their backs]].
* HyperDestructiveBouncingBall: Both fireballs, the red one especially 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. They're even a variant called "Superflies".
* 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.
* MilestoneCelebration: Nintendo declared the year 2013 "TheYearOfLuigi" to celebrate the 30th anniversary of Luigi's debut in this 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 [=SMB1=], would follow the "campaign" model.
* ShoutOut: The commercial for the "Atari" versions of the game uses a jingle set to the tune of the classic sitcom ''Series/Car54WhereAreYou''.
** {{Inverted|Trope}} in the original and Super NES versions of ''VideoGame/SuperMarioBros3''. If you enter the same space as the other player, you get to play a NewGamePlus version of this game. You must kill five enemies, like in the original, and if you hit the other player from below, you get to steal his cards. So, if you have two Stars, and the other guy has one, you can steal that card, and you'll get five extra lives, just like in the main game! You won't get the fanfare, though. The players' status (Super, Fire, Raccoon, etc.) have no effect in this game; both players are small.
** There are also a couple of extra games that load every four battles.
*** The first game has five coins in the room, and whoever gets the most wins.
*** The second game has a single pipe in the center of an open room from which coins and fireballs spew out. Players aim to get best three out of five coins while avoiding the fireballs.
*** The third game has ? boxes on three floors with ladders at the center. Players must kick open the boxes with the run button and find best three out of five coins.
** The Super NES version also has a "battle mode" which consists exclusively of this game. However, the objective here is to get five coins, not kill five enemies. Both players start out in Super form (take two hits to kill), and Super Mushrooms are provided occasionally. Whoever wins five games wins. Curiously, MercyInvincibility when hit once lasts forever if the player doesn't move (at least in the SNES version). Also, in this mode only, the fireballs are replaced with Boos, Koopa Troopas occasionally appear (and can be stomped on in order to use their shell like in other Mario games), and a new type of mushroom with a question mark on it will appear, either swapping the bros' places or inverting their powered-up states.
** And finally... There's no battle mode in the ''VideoGame/SuperMarioBros3'' portion of ''Super Mario Advance 4'', but a remake of Mario Bros. is in, and the multiplayer mode brings back the SNES version's "best 5 out of 9" format.
* SmartBomb: The POW Block.
* 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 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/SuperMarioBros games.[[/note]] Most people mainly remember this game due to it being released on '''all''' Super Mario Advance games '''''and''''' ''VideoGame/MarioAndLuigiSuperstarSaga''.
