The Cube (2009-) is an ITV GameShow where players try to perform various physical and mental challenges. Completing a challenge allows the player to go on to the next level (and increases their potential winnings), and completing all 7 levels earns the player a grand prize of £250,000. You only get 9 lives to use in your game.

But hold on, before you begin jumping to conclusions and saying that this show is basically ''Series/WhoWantsToBeAMillionaire'' meets ''Series/TheKryptonFactor'', there's just one more thing that should be noted: you have to do all the tasks within a giant four metre wide acrylic glass cube, with a limited number of lives, and chances to [[{{Lifelines}} simplify a task or practice it beforehand]]. Oh, and unlike most game shows [[WhoWantsToBeWhoWantsToBeAMillionaire patterned off of]] ''Millionaire'', every level is AllOrNothing, there are in fact ''no'' safe points at all (unless you bail out before you commit yourself to the next game, which is the only time you're actually allowed to quit by the way).

For what this show may or may not lack in originality (stunt game shows are not a new idea; see ''Series/BeatTheClock''), it truly is better than it sounds once you actually notice all the VisualEffectsOfAwesome (which are the result of this show's biggest draw aside from the game itself: its innovative camerawork and clever use of [=CGI=]) And a lot of the challenges on this show ''are'' quite ingenious at times too.

The show has been quite a hit for ITV 1, currently airing for its eighth series as of 2014. It has also spun off several international versions, all of which are filmed on set of the original in London. Over in America, CBS had greenlit a pilot for an American version not long after the first series wrapped in the UK, but ''Series/MinuteToWinIt'' likely stole their thunder. Meanwhile, Spain got their own version in 2012, which can be viewed on Mediaset España's official site [[http://www.mitele.es/programas-tv/el-cubo/ here]] with no regional lockout.

!!GameShow Tropes in use:
* AllOrNothing: Every task is an all-or-nothing gamble, and once you decide to play, you can't back out. There are no safety nets if you lose all your lives.
* CelebrityEdition: There have been quite a few celebrity editions, though they've [[ProductPlacement frequently involved]] actors from ''CoronationStreet''. A few specials also featured British athletes in honor of the upcoming Olympic Games in London.
** One of these Olympics specials featured British runner Mo Farah; who with 6 lives to spare, became the first ever contestant to beat the final round and win the £250,000 grand prize! Then he went on to win Britain's first gold medal in the Men's 10,000m.
* HomeGame: There's a "[[http://www.argos.co.uk/static/Product/partNumber/3905212.htm Family Electronic Game]]" as well as an [=iOS=] version.
* LetsJustSeeWhatWouldHaveHappened: Inverted; the "Trial Run" gives the contestant a chance to see how he might do before committing to a decision.
* {{Lifelines}}: "Simplify" (makes the stunt easier in some way) and "Trial Run" (allows the player to practice the stunt once before deciding to play on or not). While initially believed to be removed on the last level, yes, you can still use any remaining helps on it.
* Personnel:
** TheAnnouncer: Colin [=McFarlane=], personified as the voice of the Cube itself.
** GameShowHost: Philip Schofield. Justin Lee Collins hosted a pilot for Channel 4.

!!This show provides examples of:
* ArtMajorPhysics: One contestant, Nicky (series 6, episode 2), playing Pendulum for £2,000, had her boyfriend telling her to throw the ball hard. She did, and it went way over the target ball. Then both she and her boyfriend kept talking about whether to start the swing higher or lower, resulting in her sending the ball way over the top of the target ball repeatedly. Anyone who's taken an introductory-level physics course would know that the harder you throw the ball, the higher up it's going to go.
* CameraTricks: This show is probably the only excuse to use advanced camera trickery outside of ''Film/TheMatrix''. And yes, they can do BulletTime too.
* CommercialBreakCliffhanger: Notably averted. Commercial breaks are generally scheduled after a challenge has been presented to the contestant, but before the player decides whether to play on, take the money and quit, or use the Trial Run.
* DuelingShows / FollowTheLeader: ''Series/MinuteToWinIt'' started out in early development as an attempt by Creator/{{NBC}} to rip off ''The Cube'' using items you can find around your home for the stunts, although it later evolved into something more like ''Series/BeatTheClock'' shortly before its premiere. Ironically, ITV picked up ''Minute'' for its digital channel [=ITV2=], but it faced AdaptationDistillation and turned into something that some people think came out ''better'' than the US version.
* TheFaceless[=/=]TheVoiceless: The Body, a woman wearing a silver mask who demonstrates the tasks in clips, allowing the contestants to judge if they will go on or not. However, she has revealed her mouth once - to demonstrate a stunt involving blowing a ball into a glass of water - so she's not ''that'' shy, maybe.
* GameOver: When a contestant runs out of lives, the Cube announces, "Contestant defeated!" (As you lose your lives, the Cube announces how many lives you have left.)
* HardModeFiller: The final level will always end up being the game you had the most trouble with. To make it worse, it's a tougher version too.
* TheLoad: Series 6 has seen a pattern of contestants bringing along friends and family who give them outright terrible advice and are generally worse than useless. (See ArtMajorPhysics above for an example.)
* NintendoHard: All of the stunts have been tested prior to production. In the later stages of the game, they make it a point to use challenges that gave the testers the most trouble - to the point that the contestant would have to do ''better'' than the testers in terms of average lives used to complete the stunt.
* RuleOfCool: Watching someone count to ten seconds? Dull. Watching someone count to ten seconds ''in the Cube''? Awesome.
* TrailersAlwaysSpoil: When they began straddling games over two episodes, the trailers for the following week's episode often gave away at least some of the contestant's future progress. This has since been subverted; if a player's campaign is interrupted at the end of an episode, they'll go straight to the credits now.
