Ore Oduba, Vicky Pattison, Alex Brooker, Lydia Bright and Louie Spence have signed up for a celebrity charity special of 'Crystal Maze' ahead of its reboot.
Richard Ayoade
The popular 90s game show, which is making a full series comeback following the success of the one-off all-star 'Stand Up to Cancer' edition that was hosted by Stephen Merchant last year - is set to hit Channel 4 for another celebrity instalment on June 23.
'The IT Crowd' star Richard Ayoade will be the new host of the show, which follows teams trying to navigate through Aztec, medieval, industrial and futuristic zones before facing the Crystal Dome.
At the time, Tom Beck, Head of Live & Events at Channel 4, said: "'The Stand Up to Cancer' special was so brilliant and so successful that commissioning a series of 'The Crystal Maze' was almost a no-brainer. I couldn't be more pleased and excited that Richard has agreed to become the new Maze Master - he's an inspired choice."
The original series ran from 1990 until 1995 and was previously fronted by 'The Rocky Horror Show' creator Richard O'Brien and punk rocker Ed Tudor-Pole.
At the height of its popularity, the series drew in up to six million viewers per episode, making it the most popular show on Channel 4 at the time.
The contestants took part in a series of challenges and games in order to win crystals, each of which gave them five seconds in the final crystal dome.
In the finale, the teams had to grab 100 gold tokens which blew around the dome, but lost one for every silver they also had.
Just 18 out of the 83 teams who took part in the show over the years managed to win.
