Four more intrepid celebs take on Richard Osman's fiendish brain-busting challenges this week. They are Jordan Banjo, Sian Lloyd, Nick Pickard and Ellie White.

White will be known to comedy fans for a number of roles. I particularly liked her when she cropped up in the criminally underrated Vic and Bob sitcom, House of Fools. White is very good at playing weird characters. She co-starred with long-time friend and collaborator Natasia Demetriou in their own sketch show, Ellie & Natasia, which really deserved a bigger audience. She also worked with Demetriou and her brother Jamie Demetriou in the award-winning Channel 4 sitcom Stath Lets Flats.

But if Ellie White is familiar to House of Games viewers that is more likely to be because they have seen her playing Princess Beatrice alongside Celeste Dring as Princess Eugenie in the royally funny long-running Channel 4 satire The Windsors. More recently she has cropped up in more.mainstream comedy roles, in the Lee Mack sitcom Semi-Detatched and as one of the stars of the domestic comedy The Other One. If White is in something you can be pretty sure it will be worth watching.

But will she be the winner of this week's House of Games? Sam Campbell was unlucky not to win when he was on the show two weeks ago, but Campbell's fellow Taskmaster star Emma Sidi was the winner last week so comedy could be on a roll. There will be tough competition from Jordan Banjo, Sian Lloyd, Nick Pickard. You've got to be clever but you've also got to be fast to win this show.
