Richard Ayoade returns with a new celebrity special, and more importantly, a new zone to explore in the Maze. The Medieval Zone has now gone, replaced by the new “Eastern Zone”, influenced by the Far East. There is also a new element to the show – the chance to “supersize” one crystal collected during the game. The famous faces joining Ayoade tonight are Gemma Collins, James Argent, Carol Vorderman, Rick Edwards and Ellie Taylor. The Crystal Maze is on Channel 4 at 20.00.
