Richard Ayoade hosts this reboot of the popular 1990s game show, guiding five contestants through the Aztec, Medieval, Industrial and Future zones, where they play a range of skill, mystery, physical and mental challenges to win the all-important crystals. Judy Murray captains the team, guiding Paralympic legend David Weir, former footballer Wayne Bridge, Countdown's Rachel Riley and TV personality Charlotte Crosby, hoping to ace their way to the maximum time possible inside the Crystal Dome. Will Judy coach her team to victory, or will the Maze have Rachel's number?
