Richard Ayoade guides an all-star team - Tamzin Outhwaite, Phil Tufnell, Dr Ranj Singh, Francis Boulle and Joel Dommett - through the four formidable zones.

Matt Edmondson, Debbie McGee, Kimberly Wyatt, Michael Owen and Chris Hughes pit their wits against the legendary maze. But Chris has a wobble with one particularly tricky trial.

In this episode, reality TV star Spencer Matthews makes his second appearance in The Crystal Maze, but will he fare better this time with his wife Vogue Williams, a model and TV presenter, by his side? Joining them are team captain Sir Chris Hoy, the six-time Olympic gold-winning cyclist, reality TV star Jessica Wright and the Reverend Richard Coles, as they somewhat shakily navigate the pitfalls of the four zones.

This time, pop star Fleur East leads a thespian-filled team, as she guides actors John Thomson, Nina Wadia and Natalie Cassidy, as well as reality TV star Georgia 'Toff' Toffolo, on a wild ride full of twists and turns.
