When playing bumper pool, players must try to sink their assigned color of balls into their assigned pockets. Each player must hit his cue ball into his pocket before any other colored balls are hit into the pocket. If a player hits any other ball into his pocket before sinking his cue ball, the opponent gets to remove two of his own balls and put them into his pocket.
Bumper pool is played with either two opponents or two teams of four. In either case, each side has either five white balls or five red balls. One of each of these balls is marked as the cue ball. The object of the game is to be the first team or player to sink all five of the assigned color of balls into the respective color pocket.
After a player successfully shoots one of his balls into the correct color pocket, he gets to take another shot. If a player causes a ball to leave the table, the opponent is allowed to place that ball anywhere he wants on the table. The opponent may also take two of his balls and place each one in his color pocket.
There is no penalty or foul if a player accidentally sinks one of his opponent's balls. However, if a player accidentally sinks one of his own balls into the opponent's pocket, the opponent gets to drop two of his own balls into his pocket.
