[[YourPrincessIsInAnotherCastle BUT OUR PRINCESS IS IN ANOTHER CASTLE!]]''

The first game in the ''Super Mario Bros.'' series, but the [[OlderThanTheyThink fourth game overall]] that stars [[Franchise/SuperMarioBros Mario]], and the game that singlehandedly kicked off the EightBitEra. After appearing in ''VideoGame/DonkeyKong'', ''VideoGame/MarioBros'', and ''VideoGame/WreckingCrew'', the Mario brothers moved on to the game that set loads of standards. Not just for platform games, but just about any genre that used conventions established in this game.

The general story is that Bowser, the ornery King of the Koopas, has conquered the Mushroom Kingdom and turned all of her subjects into [[ThrivingGhostTown background textures]]-- er, bricks and shrubbery. The Kingdom's Princess is the only one who can revert his dark magic, but he has kidnapped her in order to prevent this. Mario, ever the gallant one, storms each of Bowser's castles looking for her. Unfortunately for Mario (and you), Bowser has several body doubles, and there's no way to tell who's the real one, so it's long road ahead.

Really, the importance of this game can be easy to underestimate by today's standards. There simply weren't games like it. [[TheGoldenAgeOfVideoGames "Golden Age" games]] were more simple, and had fallen out of favor in the US due to the TheGreatVideoGameCrashOf1983, and games on [=PCs=] were more complex, which meant they didn't have the accessibility or mass appeal.

This game hit that sweet spot in the middle. It was simple enough that it could attain mass appeal, yet it also exhibited enough depth to be stimulating for more devoted gamers. Some might dismiss its sales due to being bundled, but it was sold separately in Japan[[note]] and in North America at first[[/note]], and was still a smash hit. This game helped sell the {{NES}} to a game-weary audience, and elevated Nintendo to the top of the gaming companies.

And this of course had loads of sequels and follow-ups in the Franchise/SuperMarioBros series, as well as loads of imitators.

The original game was remade with SNES graphics along with the other NES titles in ''Super Mario All-Stars''. There was also a GameBoyColor version called ''Super Mario Bros. Deluxe''. This included a challenge mode where you had to get a high score, collect 5 red coins, and find the Yoshi egg in each stage; a two-player race mode; badges and other images awarded for achievements; a high-score table; extra utilities and printables; a hidden "You vs. Boo" mode (a one-player version of the two-player game); and a hidden conversion of ''VideoGame/SuperMarioBrosTheLostLevels''.

NobuoUematsu has stated that the theme music, originally created by Creator/KojiKondo, should be Japan's national anthem.
!!This game provides examples of:
* ActuallyADoombot: The first seven "Bowsers" are actually enemies somehow in disguise as him. Flinging fireballs at the fake Bowsers will reveal their true forms.
* AllThereInTheManual: The Koopa are a clan of sorcerers who have brought the Mushroom Kingdom to ruin by transforming its citizens into the bricks you break (and thus the items are "gifts" from the transformed citizens to help you) and various other background objects. The only one who can break this curse is Princess Pea..., er "Toadstool"[[note]] She was always called "Peach" in Japan; the eventual compromise was making her full legal name "Princess Peach Toadstool"[[/note]], which is why Bowser has kidnapped her. This bit of lore was dropped in later games.
* AlternateCompanyEquivalent: ''VideoGame/TheGreatGianaSisters''. So much that Nintendo actually sued. The later ''Giana Sisters'' games went through DerivativeDifferentiation.
** Sega's ''VideoGame/AlexKidd in Miracle World'' was not such an obvious clone, but still fits the trope (and was correspondingly packaged with or built in to the SegaMasterSystem, the NES's rival).
* AlwaysNight: Worlds 3 and 6[[note]]Although, strangely, World 6-2 has a pipe leading to an underwater bonus area where it's clearly daytime[[/note]].
* AmericanKirbyIsHardcore: The American instruction manual makes repeated references to enemies being killed. The Japanese manual merely says they are defeated.
* AnimatedAdaptation: ''WesternAnimation/TheSuperMarioBrosSuperShow'' adapts both this and ''VideoGame/SuperMarioBros2''.
** Also, the anime movie ''Anime/TheGreatMissionToSavePrincessPeach''.
* {{Antepiece}}: the game has great level design involving interesting yet accessible setpieces. One tool it'll use is to build up to a complicated setpiece with an "antepiece". For example, in the first level, there's a part with a staircase followed by a pit; jumping up the staircase without falling into the pit, and then getting over the pit, is a rather hard and scary proposition. So there's a part right before it which is mostly the same, except the pit won't kill you. This allows you to practice the setpiece in a safe environment. You can read more and see a picture of this setpiece-antepiece pair here: [[http://www.auntiepixelante.com/?p=465]]
* ArtEvolution: According to [[http://www.nintendods.com/iwata-asks-chapter.jsp?interviewId=1&volumeId=8&chapterId=4 this Iwata Asks]], Miyamoto utilised external illustrators to flesh out his rough pencil sketches since ''VideoGame/DonkeyKong''. When it came time to do this game's (Japanese) package illustration[[note]] which was eventually used in the U.S. for the "How to Win at Super Mario Bros." strategy guide[[/note]], Miyamoto had to do the art himself, since there was no time left for him to hire a mainstream artist. [[http://www.mariowiki.com/images/f/fc/SuperMarioBrosArtwork2.jpg This was the result.]] It was Yoichi Kotabe who fleshed out the designs of the characters since then. Notable mention goes to Bowser. Miyamoto himself was aiming for the appearance of [[ALoadofBull an ox]] for Bowser's design, even though he's supposed to be a turtle. Upon reflection on this, Miyamoto remarked, "I'd been drawing something completely incomprehensible - a turtle's body with an ox's head!" In a MythologyGag, Midbus, Bowser's [[TheRival rival]] from ''VideoGame/MarioAndLuigiBowsersInsideStory'', more closely resembles an ox, with some [[FullBoarAction boar]] characteristics thrown in.
* ArtifactTitle: ''Super Mario Bros.'' is a completely different game from the original ''Mario Bros.'', most notably lacking the 2P co-op mode from the original (being replaced by an alternating mode instead). As a result, Luigi's presence in the game feels rather thrown in, since it makes no difference whether the second player controls Luigi or another Mario. The sequels would try to remedy this by either: making Luigi into a selectable character with a different play-style (as seen in both versions of ''Super Mario Bros. 2'') or by adding a competitive aspect to the 2P mode (as seen in ''Super Mario Bros. 3'').
* TheArtifact: Mario and Luigi being plumbers and travelling through pipes. This made sense in ''MarioBros'', which was set in New York's sewers; not so much in the Mushroom Kingdom. However, it became an integral part of the gameplay and setting, and its incongruous nature helped create the series' WorldOfChaos reputation.
* AscendedGlitch:
** The multi-coin blocks were reportedly a programming error that was left in because they liked it.
** The Minus World. On the cartridge version it was a glitch that sent the player to a level that didn't exist; it was only by sheer luck that the level was completely playable. When the game was ported to the Famicom Disk System, the programmers replaced it with completable -1, -2, -3, which were based on other glitched levels in the cartridge.
* AttractMode: It features one, and the computer's one of the worst Mario players ever (most likely to minimize spoilers).
* BaldOfEvil: Bowser. Averted in both the original artwork and the ''Super Mario All-Stars'' remake.
* BattleThemeMusic: Averted in the original version, played straight in the ''All-Stars'' version.
* BigBad: Bowser.
* BottomlessPits: Everywhere.
* BubblyClouds: The "Coin Heaven" bonus areas.
* CheatedAngle: In the original game, the Mario Bros. always have their head to the side they're walking towards, even when they aren't moving and the rest of their body is facing the screen. The only time they ever fully face the viewer is if they're dying.
* ChekhovsGunman: See GameplayAndStorySegregation below.
* CollisionDamage
* ColorCodedForYourConvenience: Red mushrooms (extra hit point) vs. green (1-Up), red Koopas (they patrol specific areas) vs. green (they come straight at you). Oddly subverted in the Goombas, whose color-coding only matches the level.
* ColorCodedMultiplayer: There's no difference between Mario and Luigi in terms of playability.
* DeliberatelyMonochrome: World 6-3, is either this, or simply a representation of snow.
* EarlyInstallmentWeirdness:
** The backstory, AllThereInTheManual, explains how the Koopa clan transformed the citizens of the Mushroom Kingdom, and only the princess can undo this. The later games never mention this.
** The game also used RatchetScrolling, which prevented players from going back. Most Mario games after this abandoned this type of scrolling for AutoScrollingLevel in a few places while allowing backtracking in everything else.
** The timer also ticked away at a much faster pace compared to the later Mario games.
* EarlyBirdCameo: The FDS version contains Air Bloopers in level -3.
* EasterEgg:
** If you wait long enough on the title screen, then a brief demo will start to play.
** Also, run out of time as Fiery Mario.
* EliteMook: Hammer Brothers.
* EndlessGame: Famous for averting it, although technically, you can play the levels again after the ending.
* EveryTenThousandPoints[=/=]LawOfOneHundred: 100 coins equal a OneUp.
* ExcusePlot
* {{Fireballs}}: From the Fire Flower, of course.
* FlyingSeafoodSpecial: Cheep-Cheeps, which jump out of the water and into the air.
* GameplayAndStorySegregation: There is actually only ''one'' Buzzy Beetle that can be killed with fireballs in this game. [[spoiler:It's disguised as Bowser at the end of World 3-4]].
* GuideDangIt: Each x-1 level has a hidden OneUp Mushroom in it. Besides the one in 1-1, they only appear if you've gotten all the coins in the previous x-3 level or used a Warp Pipe (e.g. to get the one in 2-1, you need to get all the coins in 1-3).
* HardModeFiller: Some of the later stages. Namely Worlds 5-3, 5-4, 6-4, 7-2, 7-3 and 7-4, which are harder versions of 1-3, 2-4, 1-4, 2-2, 2-3 and 4-4 respectively. In the ''Vs.'' arcade version, these harder stages are bumped ahead and replaced with new stages that later formed part of ''Lost Levels''.
* IdleAnimation: Sort of. If you stay in one spot for 30 seconds, with a Hammer Bother nearby, the Hammer Brother will leave its perch, and actively start chasing you.
* InfiniteOneUps: Line a Koopa shell just right against a staircase at the end of 1-1 or 3-1, and your jumps will turn into a chain reaction, triggering loads of points followed by {{One Up}}s.
** GameBreakingBug: But woe to you if you exceed 127 lives, because the life counter will overflow into negative lives, causing your next death to be a GameOver.[[labelnote:Details]]The game stores your remaining lives in an 8-bit signed integer (which has a range from -128 to 127), hence the overflow.[[/labelnote]]
* InNameOnly: Aside from the presence of Mario, Luigi, turtle enemies, and coins, ''Super Mario Bros'' really doesn't have anything to do with ''MarioBros'', although it does have some similar elements (you can still attack enemies from below when they are on brick platforms).
* InvincibilityPowerUp: The Starman and its famous jingle debut here.
* KnightOfCerebus: While the franchise would eventually feature much more wicked villains in the ''VideoGame/PaperMario'' and ''VideoGame/MarioAndLuigi'' games, Bowser is still this compared to Donkey Kong and Foreman Spike. Donkey was an AntiVillain who was trying to get back at Mario for abusing him, and Spike was a regular human who also happened to be a jerk and a BadBoss, but Bowser, the draconic EvilOverlord, is genuinely intimidating.
* LethalLavaLand: The castle levels.
* Level1MusicRepresents
** The overworld theme has become the iconic theme of the Mario series, as well as nearly every crossover and non video game appearance Mario has had.
** Subverted in the ''All-Stars'' version though, which uses an arrangement of the underwater level theme as the title theme.
* MarathonLevel: Level 8-1 is looooooooooooong. Even harder than making all of the tricky jumps is reaching the end before time runs out!
* MarketBasedTitle: Subverted. Copyrights documents (and at least one brochure for the arcade version) suggest that Nintendo originally considered renaming the game ''Mario's Adventure'' for the American market, but they decided to keep the original name instead.
* MinusWorld: A famous example, [[TropeNamers coined]] by ''Magazine/NintendoPower''[='=]s coverage of the glitch. Japan, meanwhile, discovered even more such worlds through a process that involves swapping out the game's cartridge with ''Tennis'' while the console's still running.
* NintendoHard: Although at the lower end compared to other infamously hard games.
* OneUp: TropeMaker. The green OneUp Mushrooms have appeared in almost every other Mario game since.
* PacManFever: Lots of sound effects from this game have turned up in children's TV shows, particularly in scenes set at arcades (there were arcade cabinet versions of the game, but it's unlikely any of those writers knew that).
* PaletteSwap: Not just with enemies; the bushes and clouds use the same tiles.
** Backgrounds, too; Worlds 3 and 6 apparently take place at night.
* PipeMaze: World 8-4. The pipes are the key to progressing through the level, and going down the wrong one will send you back to the beginning.
* PlatformGame: TropeMaker and TropeCodifier for many platform tropes.
* RatchetScrolling
** Required by the way levels were stored. Each "object" in the level had a "page select" flag which, when set, told the game to advance one screenful to the right. There was no code for going back one screen, however, and as there could be a variable number of objects per page, the algorithms involved would have been a bit too complicated for the [=NES=], where every byte and every clock cycle counted (and they were already running low on [=ROM=] space as it was). So while the game could be told to go to the ''next'' screen, there was no way to start loading objects from the ''previous'' screen, hence why you can only go right.
** The Game Boy Color version does allow you to scroll back slightly, but only because the screen is smaller than the NES version's.
* RearrangeTheSong: The Vs. arcade version totally redid the ending theme. In addition, a Hi-Score theme was also added.
* SaveThePrincess: And she's in another castle.
** YourPrincessIsInAnotherCastle: There you have the TropeNamer.
* SlippySlideyIceWorld: Worlds 3, 5 and 7, although "snow" in this game is just recolored trees and pipes. The ''All-Stars'' version of the game improves on this by making the ground actually look snowy.
* SuperDrowningSkills[=/=]SuperNotDrowningSkills: Yes, both of them. If you're underwater, nothing aside from the standard timer can stop you from staying under for as long as you want. On the other hand, falling into a pit filled with water doesn't even slow your fall.
* ThisWasHisTrueForm: If defeated with fireballs rather than being thrown into the lava, the Bowsers of Worlds 1-7 are revealed to be simple minor enemies which have taken Bowser's form, likely using more of that Koopa Clan magic you only ever hear about in the manual.
* TimedMission: Every single level. The timer also counts down faster here than in Mario's later games.
* UndergroundLevel: World 1-2 and World 4-2.
* UnderTheSea: World 2-2 and World 7-2.
* UpdatedRerelease:
** ''Vs. Super Mario Bros.'', an arcade version, has its difficulty adjusted for arcade play. Most notably the harder "filler" versions of early stages replace their easier counterparts and new stages were added to fill in the gap during the later half of the game. These new stages were later included in ''VideoGame/SuperMarioBrosTheLostLevels''.
** ''Deluxe'' on the GameBoyColor, which also had ''The Lost Levels'' as UnlockableContent.
** ''VideoGame/SuperMarioAllStars'' which also had, besides the first SMB and ''The Lost Levels'', ''VideoGame/SuperMarioBros2'' and ''VideoGame/SuperMarioBros3''. And, in an Updated Rerelease of an Updated Rerelease, ''VideoGame/SuperMarioWorld''.
* WhenAllElseFailsGoRight: The RatchetScrolling prevents Mario from going left.
