Kasparov led by 3 points after 16 games but Karpov fought back with three straight wins to level the score with five games to go. After two tense draws, Kasparov won the 22nd game and drew the 23rd to clinch the retention of the World Championship. The 24th game was played to determine the distribution of the prize fund. It was drawn so Kasparov received the winner's share of the purse. Had Karpov won, the match would have ended in a tie and the purse would have been equally divided.
