Maze Master Richard Ayoade guides the third team of intrepid celebrities: Joel Dommett, Jermaine Jenas, Adil Ray and Tamara Wall, led by team captain Rylan Clark-Neal through the epic game show adventure where they hope to win in aid of Stand Up to Cancer. There are four fantastical zones: Aztec, Medieval, Industrial and Futuristic. In each zone the team must tackle Physical, Skill, Mystery and Mental challenges in a bid to win crystals. These elusive crystals each give the team five seconds in the final test: the iconic Crystal Dome where they hope to collect gold tokens to win prizes.
