-->''Toooooooooooooooo the Crystal Doooooome!''

British GameShow running from 1990 to 1995, initially hosted by Richard O'Brien and later by Edward Tudor-Pole. Produced by JacquesAntoine. A remake of ''Series/FortBoyard''. (Channel 4 originally ''wanted'' ''Fort Boyard'', but couldn't get at the fort itself as the French series was massively popular at the time.)

Each week, six contestants would have to complete a series of challenges in four adventure zones (at first- Industrial, Futuristic, Aztec and Medieval. In the fourth series, Ocean replaced Industrial). Completing these challenges would mean receiving a time crystal. If contestants failed to leave the room (crystal or not) before time ran out, or broke certain rules in some games, they were locked in and could only be released in exchange for a crystal.

The final part was always the Crystal Dome, where contestants would have a certain amount of time (determined by how many crystals won- 5 seconds per crystal) to collect gold tokens[[labelnote:*]]more like tickets or bills[[/labelnote]] blown about by a big fan. Silver tokens were also present and these would result in a deduction from a score (which could- and often did- lead to a ''negative'' total score). If they got over a certain total, they would win prizes: usually adventure holidays in B-level British resort towns.

Most of the show's appeal came from the wonderfully eccentric Richard O'Brien (of ''RockyHorrorPictureShow'' fame) and the way he would present the show: his manic, restless behaviour; his razor-sharp put-downs of (frankly bad) team performances; and how he would always play that damn harmonica at the most inappropriate and distracting times. Edward Tudor-Pole [[ReplacementScrappy never had a chance]]. It also became common for the viewer base to start shouting at the screen at the contestants when [[RealityShowGenreBlindness they missed]] the very obvious solutions. (Extracts from the show's blooper reel that have been leaked onto [=YouTube=] reveal that, in the privacy of the technical gallery, the show's director did it too.)

Although it wasn't very apparent to the viewer most of the show was in fact fixed: For example it was the production staff not the Captain that decided what games to play (Physical, Mental, Skill or Mystery) and was in fact decided well in advance of the show. Although on screen it looks instantaneous there was also significant length of time between a contestant entering a puzzle room and actually playing it sometimes in the region of 15 minutes. This was so the crew could set up equipment such as cameras and in some instances to actually reset the game if the player in question mucks up too badly in order to keep it interesting to the viewer. A far more in-depth list can be found on the other Wiki.

There were also SpinOff ChooseYourOwnAdventure style books, set in a more elaborate version of the Maze: ''The Crystal Maze Adventure Gamebook'' by Dave Morris and Jamie Thompson aimed at teens and adults, in which the more "realistic" maze was justified by it being set [[ExtyYearsFromNow a hundred years in the future]], with advanced holographics and robotics (including the robot host [[FunWithAcronyms ROB]]); and four targeted at younger readers (''The Crystal Thief'', ''Tea at Rick's'', ''The Sacred Necklace'' and ''Phantom in the Tower'' all by Peter Arnold), which just {{Handwave}}d it.

The show remains a classic and repeats are still shown in syndication, while [[EpilepticTrees rumours]] surface every couple of years about a {{Revival}}. The show was and remains very popular amongst University Students, though there have been no DVD releases as yet.

!!This show contains examples of:
* ApothecaryAlligator - A Mystery Room in the medieval zone was dressed as an alchemist's laboratory, complete with stuffed crocodile (with a clue in its mouth).
* BaldOfAwesome - Richard O'Brien.
** MessyHair - Ed Tudor Pole, the replacement.
* BambooTechnology - A feature of the Aztec Zone.
* BerserkButton - Don't tell the contestant "You've got plenty of time", or Richard O'Brien will get very annoyed.
* CaptainObvious - Most of the team "advice" during certain games. Not that the obvious advice was necessarily unhelpful to their teammates...
* CarriedByTheHost
* CatchPhrase - "This is a two/two and a half/three minute game from the very second I close the door...", "Will you start the fans, PLEASE!"
* ComicallyMissingThePoint: On more than one occasion, a contestant completely fails to understand their task, leading O'Brien to helpfully offer advice on what to do. When they ''still'' don't get it, O'Brien will offer the advice again... and again... and ''again''. He's clearly getting irritated at these utter morons!
** One episode had a contestant simply stand there with a dumbfounded look for the entire 5 minutes.
* ChristmasEpisode - Kids' special
* FifteenPuzzle - Sometimes appeared as a challenge.
* FortuneTeller - One of the inhabitants of the Medieval Zone was a stereotypical fortune teller who asked quiz questions and handed over a crystal (which was hidden in the base of her crystal ball) if the contestant answered correctly. O'Brien would provide the contestant with silver coins to cross her palm with.
** The fortune teller is his in-show mother, 'Mumsie', something that O'Brian made up on the spot during a first-series episode and it stuck.
*** In Series 3, 'Mumsie' was replaced by 'Auntie Sabrina' - which was strange, because they were both played by Sandra Caron (possibly it was just an elaborate excuse to change her costume, as the characters did dress differently).
* GoldenSnitch - The Crystal Dome.
* HeyItsThatGuy - In all his wonderful ham-flavored glory, it's a wonder that Richard O'Brien didn't break out into the Time Warp during his run on the show. One might even go so far as to say it's astounding. (Though there is at least one episode where he goes so far as to remark during a challenge that "time is fleeting".)
** Amusingly, Ed Tudor-Pole ''also'' played Riff Raff in ''Rocky Horror'' before he took over as host here (in the 1990 London live theater revival- where he'd been cast and approved of in the part by Richard O'Brien, no less)!
* ImpossiblyTackyClothes - Mr O'Brien dresses like a fashion designer, that is to say like a man who knows nothing about style.
** Not to mention the team uniforms.
* LargeHam - Richard O'Brien. Ed Tudor Pole tries to go one up, but doesn't quite make it.
* LaserHallway - Sometimes appeared as a challenge in the Futuristic Zone (but using tripwires -- they probably didn't have the budget for real lasers).
* LoopholeAbuse - It wasn't unknown for contestants to obtain their crystals in ways they weren't really supposed to.
* {{Mayincatec}} - The Aztec Zone.
* MineralMacGuffin
* OnlySmartPeopleMayPass - Although the audience might have argued that it was more like "Only a ''complete idiot'' cannot pass".
* PirateBooty - One of the challenges in the Ocean Zone was searching for the key to a treasure chest in a pirate cave, complete with pirate skeleton and stuffed PirateParrot.
* PutOnABus - Richard O'Brien, when he left the series.
* ShaggyDogStory - Ultimately, the number of crystals gathered meant nothing if the team gather too many (negative-scoring) silver tokens in the final stage. And they frequently did. (In theory, they could have used the extra time to check for silver tokens instead of just shoving in as many as possible, but apparently no-one ever thought of that.)
** Conversely... [[http://www.youtube.com/watch?v=faQ1TfarvZY One Crystal + Crystal Dome]] = EpicFail
--> '''O'Brien''': I'm not going to wish you luck, it's a ''complete'' waste of time!
* ThemeTune - [[http://www.youtube.com/watch?v=GjRnyyJLNy0 Much more dramatic than it has any right to be]]
* TimedMission - Every challenge is 2-3 minutes long. The crystal dome has 5 seconds per crystal earned.
* TimeTravel - Some of the challenges seem to take place in a medieval time period, or the future, or something similar...
* TooDumbToLive - Several contestants, although [[http://www.youtube.com/watch?v=KAHG2zxX_rE this]] is probably the most ludicrous example.
* VoodooDoll - Used for a throwaway gag in a series 2 episode:
-->'''Richard''': Oh look, it's one of Mumsey's pin cushions. Strange thing, she has a thing about pin cushions, and she always makes them in the shape of little people, I can't think why.
* WireDilemma - Sometimes appeared as a challenge.
* [[YourPrincessIsInAnotherCastle Your Crystal Is Not In This Game]]: In the fourth series, a game involved creating a chain of words to release a sword from a stone (King Arthur reference). That sword had a crystal as the pommel, but the game had no crystal for the winner. Where is the crystal?[[spoiler: In the hand of a suit of armour, possibly worn by a crew member, who is given the crystal-pommel sword by Richard O'Brien.]]
