[[caption-width-right:350:Round and round and round they go! Which door's the right one, nobody knows...]]
What the heroes are looking for is behind one [[DoorTropes door]]. The problem is that the heroes stand in a long hallway or circular room lined with doors in any direction they care to proceed. Every other door but the exit has something [[AddedAlliterativeAppeal disheartening, dopey, dangerous, disastrous or deadly]] on the other side, but none of them are marked or visibly distinct from each other, so they have no choice but to try each one to find the way out. Named for the game of chance in which there's only one way to win and many ways to lose, DoorRoulette is the same thing -- lots of doors lead nowhere (or nowhere ''good''), but only one is the way forward.

The one trying the doors must be quick and slam the door before the danger on the other side emerges (or reaches out to grab them)!

Riddles, such as KnightsAndKnaves, may play some part in the process of deciding which door is the one that leads to reward or safety rather than confusion or danger. More enterprising or less white hatted heroes may fudge against the rules a bit and find [[TakeAThirdOption a more creative method]] to determine which door is the one they want. Sometimes the danger behind the doors is the villain who can do the OffscreenTeleportation trick and be behind each door progressively.

In order to save money on camera shots or the wacky StockFootage, sometimes the shot would show the character opening the door, accompanied by a sound effect that indicates a wild animal, monster or other unexpected danger lurks on the other side without ever showing it. With CGI being more prevalent in filmmaking, though, this is becoming less of a problem. If the scene is lighter fare and/or PlayedForLaughs, you can expect the StandardSnippet from "Yackety Sax" to accompany those trying the doors. The funnier the setting, the more likely it is that an oncoming locomotive will show up behind one of the doors.

An occasional variation is to have a room with no way out but the door one came in through, but opening it the second time, it now leads someplace else.

A form of MalevolentArchitecture. Not to be confused with ScoobyDoobyDoors although often the long shot down the hallway is something both tropes have in common. If the door takes the hero back to the entrance, it's OneOfTheseDoorsIsNotLikeTheOther. For the video game version, see MagicalMysteryDoors.

[[folder: Anime and Manga ]]

* In the original ''Manga/YuGiOh'' manga, when Shadi is trapped inside Dark Yuugi's mind, he was forced to do this to find his way out. One door contained the true mind of Dark Yuugi while countless others held nasty surprises. It was implied that had his adversary not shown a rare bit of mercy and helped him at the last moment, he would have been lost there forever.
* The English dub of ''Anime/DuelMasters'' uses heavy editing to throw Mimi into this situation in one episode.

[[folder: Comics ]]

* There was once a recurring ArchieComics strip called ''Open the Door, Dilton'', where Dilton Doiley would open doors leading to {{Visual Pun}}s based on their labels; a door leading to 'Tennis Court' featured a player being sentenced a $500 fee for a double-fault by the judge, and a 'Roller Derby' had people racing derby hats on wheels.
* The ''[[ComicBook/MyLittlePonyFriendshipIsMagicIDW My Little Pony: Friendship is Magic]]'' comic book had Chrysalis challenge the Mane 6 to find her behind one of the doors in her castle.

[[folder: Film ]]

* ''Film/{{Labyrinth}}'' has the KnightsAndKnaves riddle variation.
* ''Film/HarryPotterAndTheOrderOfThePhoenix'' has this when Harry and his friends are in the Department of Mysteries and they're trying to find which door is the one with all the glass balls seen in Harry's dreams.
* ''WesternAnimation/YellowSubmarine''.

* In ''Film/WillyWonkaAndTheChocolateFactory'', the "one door leads to two different locations" variation is used.
* In the EnsembleCast comedy ''Film/NothingButTrouble'', there is a sequence where a character tries to open several doors in a hallway, only to find bizarre things like tombstones or a room full of bats (and guano). Unusually for this trope, they're not stock footage but actually there. It's a very strange house.
* In the 1949 film ''I Was a Male War Bride'', French army captain Henri Rochard (CaryGrant) experiences a variation on this trope. In the hallway of a U.S. Army office building in post-war Germany, he experiences AcronymAndAbbreviationOverload in a hallway filled with solid office doors labeled with alphabet soup acronyms. He recites what he thinks the acronym on each door means until he comes to the women's restroom. He starts to recite what he thinks the acronym "LADIES" might stand for when a female corporal walks out.
* In ''Film/CasinoRoyale1967'', Sir James and MoneyPenny end up in a hall with many doors which all look alike.

[[folder: Game Show ]]

* ''Series/ThePriceIsRight'' did it with the Showcase game at the end of the show.
* ''[[TreasureHuntUS Treasure Hunt]]'' used to do it with good prizes and booby prizes they called "klunks".

* The American version of ''Series/HellsKitchen'' has an unusual variation. In the finale, Gordon Ramsay shows doors to the audience. The finalists stand behind the doors, and only the winner's door is ''unlocked''.
* Often used on ''TakeshisCastle'' for various events and challenges.
* Subverted on ''Silent Library''. A recurring punishment is "Bad Door", with punishments including a zombie, a motorcycle spewing exhaust, and more.

[[folder: Literature ]]

* [[http://www.eastoftheweb.com/short-stories/UBooks/LadyTige.shtml The Lady or the Tiger]] by Frank Stockton.
** Jack Moffitt wrote "The Lady and the Tiger" which is a continuation of the above story. In it, [[spoiler: the door the princess pointed to had the tiger behind it. The man who opened the door then quickly opened the other door, behind which stood his beloved. He hid himself behind the two open doors and the tiger killed the girl. He turned out to be one of the two thieves who died with Christ.]]
* The Literature/HarryPotter example in Film, above, also applies for the book that preceded the film. In fact, in the book there's actually a scene where the doors spin around the group like an actual roulette wheel.
* ''Seven Ancient Wonders'' by MatthewReilly has a pair of these puzzles in rooms as {{Death Trap}}s. The rooms quickly fill up with quicksand, and were designed to be disorientating to make it harder to find the correct door.
* The second of Creator/EdgarRiceBurroughs' ''Venus'' novels had one of these: only one of the room's multiple doors led to safety; all the others were deathtraps. (Once the jailers brought you in and left, the lights went out and the floor spun for a while so you'd lose track of which was the safe door.) Food and drink were provided -- most of it poisoned. Oh, and to discourage hesitation, after a while dangerous snakes started slithering in.

[[folder: Live Action TV ]]

* Candice set up a fixed, unwinnable version of DoorRoulette with her illusion powers in season 1 of ''Series/{{Heroes}}''. No matter what door Micah ran to, ''all the doors'' led him back to the room he was trying to leave.
* In ''TheTenthKingdom'', our heroes get past this trap in an unusual way: the father has had it at that point, so he picks up the toad who serves as the keeper and [[TakeAThirdOption tosses him into the corridor beyond one of the doors]], which immediately erupts into flame. They then decide to take the other door.
* ''TheMonkees'' - In the episode “Monkee Chow Mein,” Micky and Peter must choose between four doors to escape sudden death from the clutches of [[YellowPeril evil Chinese Restaurateurs]].
* In ''Series/{{Batman}}'' Catwoman did it with the choice of "The Lady or the Tiger", giving Batman a chance to catch her or die.
* In the ''Series/DoctorWho'' episode "[[Recap/DoctorWhoS32E11TheGodComplex The God Complex]]", there's an eerie hotel in which each room contains the worst fear of someone who has once been trapped in it. Finding the door meant for you means a perversion of your particular faith and subsequent death. There is no door out unless you have no faith in the first place.

[[folder: Music ]]

* The Music/HueyLewisAndTheNews video for "Heart And Soul" has Huey and the girl trying to escape from a house with a long hallway. One of the doors leads to a wild party.

[[folder: Radio ]]

* In ''Radio/TheGoonShow'' episode "The Yehti", Seagoon finds himself in a building where there is an express train behind almost every door, and flocks of sheep behind the rest. Later, accompanied by Eccles and Bluebottle, he follows Yeti tracks and finds himself in a hallway with a large number of doors. Opening each door in turn, they find things that Seagoon can perceive but the other two can't, things that the other two can perceive but Seagoon can't, things that the ''audience'' can perceive but the protagonists can't, the narrator taking a bath, attractive women who offer Eccles grapes and an explosion that, [[OnceAnEpisode as usual]], 'deads' Bluebottle. Only one door remains -- surely the Yeti must be behind it? [[spoiler:No, another express train.]]

[[folder: Video Games ]]

* One of the duel mini-games in ''VideoGame/MarioParty'' has 12 switches in a circle. Eleven of them are hazardous; the object is to be the first to find the safe switch.
* One of the co-operative mini-games in ''VideoGame/WiiParty'' has the actual doors -- some of them have boxing gloves on springs, some have wheels that run you over, and some have other Miis on the toilet.

[[/folder]]

[[folder: Western Animation ]]

* The Ghost Zone in ''WesternAnimation/DannyPhantom'' has doors like this that float in midair instead of lining the sides of a hallway. They lead back to Earth, to other places in the Ghost Zone, or to other dimensions or even other time periods. In an odd twist, the Ghost Zone actually has been mapped, so whoever has the map won't have the problem of guessing which door leads where.
* [[WesternAnimation/TheSimpsons Bart Simpson]] encounters this when he's in the Shelbyville Zoo trying to leave without being eaten by a tiger.
* WesternAnimation/LooneyTunes:
** ''BugsBunny and The Three Bears'': Bugs was trying to escape the house, but behind every door he tried was Mama Bear, whom he had seduced in an earlier scene. "Tell me more about my eyes!"
** In the 1944 short "Plane Daffy", Daffy Duck flees to various exits from Axis spy-tomato Hata Mari — but finds her behind every door, holding progressively more dangerous weapons.
** In "Yankee Doodle Daffy", talent agent Porky is trying to flee his own office but finds Daffy behind every door, doing a succession of musical numbers.
* Happened in the ''WesternAnimation/CourageTheCowardlyDog'' episode "Courage in the Big Stinking City", where behind door number 1 is StockFootage of [[Franchise/{{Godzilla}} King Ghidorah]], behind door number 2 is stock footage of a shark, and behind door number 3... is a cute girl playing a violin. [[spoiler: Until she turns around, revealing a monstrous screaming face.]]
* Happens frequently on ''WesternAnimation/MuppetBabies'', where opening the closet door can be a risky proposition.
* In the first ''[[WesternAnimation/TeenageMutantNinjaTurtles1987 Teenage Mutant Ninja Turtles]]'' cartoon, Leonardo and Raphael are in a hallway with a lot of doors in the Technodrome, when they decide to try to open them. From behind the first a missile comes out, but Leonardo says that there can't be missiles behind every door. Naturally, behind the second are about 20 Foot soldiers!
* The {{Filmation}} ''Franchise/{{Batman}}'' episode "The Nine Lives of Catwoman" started with this.
* The WarnerBros ''WesternAnimation/BatmanTheAnimatedSeries'' had an episode where Batman and Robin had to save Commisioner Gordon from a virtual reality simulation constructed by ComicBook/TheRiddler. The first obstacle Batman encounters is a DoorRoulette. This being the Riddler, however, the doors were all labeled with clues as to what was behind them. The door labeled "crazy intent", you guessed it, had an oncoming locomotive.
* FleischerStudios cartoon ''WesternAnimation/BimbosInitiation'' has this happen.
* One episode of ''WesternAnimation/GarfieldAndFriends'', "Mystic Manor", had Garfield searching a haunted house for Odie and encountering this. Behind one door was [[ShoutOut Nancy and Sluggo]], behind another was the manor's crazy caretaker taking a shower, and behind another was a sunny beach crowded with surfers, which results in Garfield being drenched by a huge wave.
* In the ''WesternAnimation/EekTheCat'' episode "[=HallowEek=]", Eek was running around a room at the haunted house freaking out, and opens three doors, but there are different monsters behind them that scare him, and then he opens another door and [[MisterRogersNeighborhood Mr. Rogers]] is behind it uttering "Won't you be my neighbor?", which also scares him.
* In the "Mad Mod" episode of '' ComicBook/TeenTitans'', the Titans try to escape Mad Mod's "school". There's a wacky J-Pop number and the DoorRoulette is crossed over with ScoobyDoobyDoors as the doors change problematically from second to second due to Mad Mod being an illusionist.
