In this special festive edition, four famous faces go head-to-head testing their general knowledge skills in a variety of fun trivia-based games in Richard Osman’s Christmas House of Games. For one night only, the celebrity contestants - Sarah Hadland, Alex Horne, Craig Revel Horwood and Charlene White - will take on a series of quiz rounds selected by the host, quiz legend Richard Osman. A winner will be declared following a quick-fire round at the end of the show, and they will be taking home a prize and the House of Games Christmas trophy.
