Three fouls in a row

Three consecutive fouls is loss of game, however the opponent or tournament referee must notify the player that is on two fouls, prior to their third foul. Should no notice occur until after the shot resulting in the third foul is in motion, it is not immediate loss of game, but the player will be considered to be on two fouls for their next shot.
The three fouls rule is often waived in after hours situations by agreement between the players.
