The cue ball is the white ball used to drive the other balls into the pockets in pool. When the cue ball enters the pocket during a shot, it is deemed a foul regardless of the rules. This is referred to as a scratch by most players and rule manuals. A white ball that has been scuffed or scratched while in play cannot be reused until it is replaced. The object of the game is to sink all of your opponent's balls using only your pool stick. You do this by hitting the red balls with the white ball, which is called making a shot. There are several types of shots you can make, such as straight shots, hook shots, spin shots, and breakaways. To start the game, both players stand at opposite ends of the table facing each other. Each player will have a rack of 10 balls, one of which is the cue ball. Before the first player can make a shot, the balls must be removed from the table. The person who removes them last loses! After the balls are removed, the player who made the last shot decides where they will be placed on the table. Then they take their stance and wait for their opponent to make a shot. If the player fails to make a legal shot, then they lose that turn and can not make any more plays until they win the roll.
