Two players are selected and are blindfolded. They then attempt to play a game of pool (either 8 or 9 ball) The only only help they get is the helper telling them where the cue ball is. Other than that they are on their own. They have to play the game as normal, following all rules. The player who pots the either the 8 or 9 ball legally is the winner. All players can then swap or the looser has to stay on the table.
