New series. The popular 1990s game show returns for a fifth run in its reworked, updated incarnation. Richard Ayoade guides five enthusiastic competitors, who are paid to play computer games for a living, on an epic adventure through 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 them five seconds inside the iconic Crystal Dome, where they hope to collect gold tokens to convert into prizes.
