Richard Ayoade hosts as team captain Laura Whitmore leads Chris Ramsey, Perri Kiely, Jordan Banjo and Gareth Thomas through the notoriously tricky challenges of the mighty maze.

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.

This time, pop star Faye Tozer steps up as team captain of the latest celebrity supergroup to tackle The Crystal Maze. Back-up comes from her vice-captain, comedian Nick Helm, and teammates, Hollyoaks actor and comedian Richard Blackwood, The Chase quizmaster Anne Hegerty, and Jordan Stephens, half of the hip-hop duo Rizzle Kicks.

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.
