Although Briggs and Robinson state that 8 players will leave with nothing, normally the losing celebrities receive a "house" amount to give to their chosen charity[citation needed], as well as their own fee for appearing on the show[citation needed]. In some celebrity editions, two celebrities have represented one position in the game, with the two conferring before giving their answer. There have also been several editions featuring entirely celebrity couples. A Christmas edition of the programme was also aired in some years. Some contestants, such as Christopher Biggins, Peter Duncan and Basil Brush, have appeared several times.
