The Crystal Maze

The Crystal Maze is a game show aired on Channel 4. It originally aired from 1990-1995 with two presenters, Richard O'Brien and Ed Tudor-Pole. It remained popular after its cancellation, mainly because its aged appearance and the hairstyles of the contestants were entertaining enough for viewers watching on the Challenge channel many years later. It was revived in 2017.

Premise
A team travels through four different themed zones (Aztec, Industrial, Futuristic, Medieval, Ocean) to win as many crystals as possible. Each crystal is worth 5 seconds inside the Crystal Dome finale.

The team leader nominates a team player they think would be best for the challenge even though they probably just met. Puzzles were categorised as mental, mystery, physical and skill. If the team player can't complete the puzzle, they can abandon it and return with no crystal, unless it is an automatic lock-in where if they fail, they are locked in. Team members can decide whether to use a crystal to free a locked in member or leave them there in exchange for more time.

The finale consists of the players being locked in a dome. Air vents blow golden or silver tickets up in the air and the players must catch them. If they catch 100 or more golden tickets, they win the prize. Silver tickets deduct the number of gold tickets.
