Samantha Womack, Rory Reid, Anne Diamond and James Acaster (2/5)

Every day this week the celebrity contestants - actress Samantha Womack, Top Gear's Rory Reid, broadcaster Anne Diamond and comedian James Acaster - take on a series of challenging quiz games selected by the host, teatime quiz legend Richard Osman. A daily winner is declared following a quick-fire round at the end of each show as the scores are tallied across the week, resulting in an overall champion being crowned on Friday. Will the winning star opt for the much-coveted House of Games pillow & duvet set, or instead go for the must-have branded dartboard?
