9-Ball Rules
The game is played with nine object balls numbered one through nine and a cue ball (the white ball).
The aim is to pocket the 9-ball with a legal shot. On each shot the first ball the cue ball contacts must be the lowest-numbered ball on the table, but the balls need not be pocketed in order.
Opening break
Second Shot of the Rack – Push Out
If no foul is committed on the break shot, the shooter may choose to play a “push out” as his shot, indicated by pressing the "Push out" button in the lower left corner. "Wrong Ball First" and "No Rail" fouls are suspended for the shot. If no foul is committed on a push out, the other player may play the next shot, or may pass the shot to the opponent.
Continuing play
A player is entitled to continue shooting until he fails to legally pocket a ball. It is no foul if he fails but then the opposing player is next.
A player has to complete one shot in 60 seconds, otherwise a foul is called, and incoming player gets cue ball in hand.
If the 9-ball is pocketed by a foul shot then the 9-ball is respotted.
Fouls
If the shooter commits a foul, play passes to his opponent. The cue ball is in hand, and the incoming player may place it anywhere on the table.
Win or Lose
If a player legally pockets the nine ball on any shot (except a push out), he wins the rack.
If a player fouls three consecutive times on three successive shots without making an intervening legal shot he loses the game.
