Based on the classic noughts and crosses game, there's a grid of nine boxes, each one with a celeb inside. They have to answer questions and the contestants must say whether they agree or disagree with the answer.
If the celebs answer the question correctly, the contestant wins that square, and if they win three in a line – horizontally, vertically, or diagonally – they win the round and money.
Tonight Dame Edna Everage, Lucy Pargeter, Patrick Monahan, Ashleigh and Pudsey, Rufus Hound, Carol Vorderman, and Roisin Conaty are in the boxes.
