The Crystal Maze is a British game show that first aired in 1990. It features teams of contestants who navigate through different themed zones, each filled with various challenges and puzzles. The goal is to earn as many crystals as possible, which provide time in the final challenge. In the final round, contestants use the crystals to gain time inside the Crystal Dome, where they must collect as many gold tokens as possible while facing strong winds. The show is known for its unique set design, engaging challenges, and the charismatic hosting of Richard O'Brien and later Ed Tudor-Pole.
