Door Roulette

What the heroes are looking for is behind one 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 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, Door Roulette 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 Knights and Knaves, 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 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 Offscreen Teleportation trick and be behind each door progressively.

In order to save money on camera shots or the wacky Stock Footage, 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 Played for Laughs, you can expect the Standard Snippet from "Yackety Sax" to accompany those trying the doors. The funnier the setting, the more likely it is that the 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 Malevolent Architecture. Compare with Elevator Gag, one of whose variations produces a similar effect through the change of floors. Not to be confused with Scooby-Dooby Doors 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 One of These Doors Is Not Like the Other. For the video game version, see Magical Mystery Doors.

Advertising

 * There's a Kraft Macaroni & Cheese commercial where Cheeseasaurus Rex is wandering up and down a long hallway of all white doors trying to find the Macaroni and Cheese. He finds various silly and amusing things before he finally finds what he's looking for.

Anime and Manga

 * In the original Yu-Gi-Oh! 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 Duel Masters uses heavy editing to throw Mimi into this situation in one episode.

Comic Books

 * there was once a recurring Archie Comics strip called Open the Door, Dilton, where Dilton Doiley would open doors leading to Visual Puns 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.

 * In the Ensemble Cast comedy Nothing but Trouble, 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 (Cary Grant) experiences a variation on this trope. In the hallway of a U.S. Army office building in post-war Germany, he experiences Acronym and Abbreviation Overload 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 the 1967 comedic version of Casino Royale, Sir James and Moneypenny end up in a hall with many doors which all look alike.

Literature

 * "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,
 * The Harry Potter example in Film, above, also applies for the book on which the film is based.
 * Seven Ancient Wonders by Matthew Reilly has a pair of these puzzles in rooms as Death Traps. 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 Edgar Rice Burroughs' 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.

Live-Action TV

 * Candice set up a fixed, unwinnable version of Door Roulette with her illusion powers in season 1 of Heroes. No matter what door Micah ran to, all the doors led him back to the room he was trying to leave.
 * In The Tenth Kingdom, 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 tosses him into the corridor beyond one of the doors, which immediately erupts into flame. They then decide to take the other door.
 * The Monkees - In the episode “Monkee Chow Mein,” Micky and Peter must choose between four doors to escape sudden death from the clutches of evil Chinese Restaurateurs.

 * In the Doctor Who episode "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.

 * The Price Is Right did it with the Showcase Showdown.
 * Treasure Hunt used to do it with good prizes and booby prizes they called "klunks".

 * The Huey Lewis and The News 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. One leads to the band singing. Another leads to a vampire biting a victim. The next, to a track with an old-fashioned locomotive racing toward them, all of which Huey slams closed before finally finding the door leading back out to the normal world. Watch it here, starting at approximately 2:53.

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, as usual, 'deads' Bluebottle. Only one door remains—surely the Yeti must be behind it?

Web Comics

 * A nice webcomic example in Adventures Of Dr Mc Ninja, in the "Punch Dracula" arc.

Western Animation

 * The Ghost Zone in Danny Phantom has doors like this that float in midair instead of lining the sides of a hallway.

 * In the Eek! The Cat 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 Mr. Rogers is behind it uttering "Won't you be my neighbor?", which also scares him.
 * In the "Mad Mod" episode of  Teen Titans, the Titans try to escape Mad Mod's "school". There's a wacky J-Pop number and the Door Roulette is crossed over with Scooby-Dooby Doors as the doors change problematicly from second to second due to Mad Mod being an illusionist.
