Every day this week, celebrity contestants Deirdre O'Kane, Jay Rayner, Tessa Sanderson and Iwan Thomas take on a series of quiz rounds selected by the host, quiz legend Richard Osman. A daily winner is declared following a quickfire round at the end of each show, and the scores are tallied across the week, resulting in an overall champion being crowned on Friday. Will the winning stars opt for the much-coveted House of Games decanter, or will they be tempted by the House of Games retro bag?
