Are you ready for a game of 9 ball pool? You must hit the lowest numbered pool ball on the table before hitting any other ball. This is called the "target ball". If you or the computer sinks the cue ball or you fail to hit the lowest ball on the table, then you have "scratched" and the other player can place the cue ball anywhere on the table that they want. This is known as a "ball-in-hand". A player wins the game after sinking the 9 ball without breaking any of the above rules. If a player happens to sink the 9 ball without hitting the designated "target ball" first, then the computer is the winner. enjoy arcade phase pool games.
