Also known as 14.1 continuous pool. This game is played on a pocketed table with the fifteen object balls and a cue ball. Every shot must begin with a call, and if made, you get to continue calling shots. The idea is to reach a predetermined score before your opponent. When all but one ball remains, the rack is started over without the apex ball in position, and the last shot is called in such a way as to break the new rack and continue play.

This is a term used to refer to all the different aspects involved in setting up a shot, i.e. the stance, grip, bridge, and stoke.

One of the alternating turns players (or doubles teams) are allowed at the table, before a shot is played that concedes a visit to his/her opponent (e.g. "he ran out in one visit"). Usually synonymous with inning as applied to a single player/team, except in scotch doubles format.

A form of Carom billiards for the masters of the game. Played the same way with two cue balls and a single object ball.

Also tiptool, tip-tool. Any of a class of maintenance tools for cue tips, including shapers, scuffers, mushroom trimmers, tappers, burnishers and tip clamps. Road, league and tournament players often carry an array of tip tools in their cases. The term is generally not applied to cue chalk.

This is a particular shot where the potential for a miscue is higher because of the amount of draw that is attempted on the cue ball.

Cut Throat is a game of pocket billiards created to support three or five players. Balls are assigned to each player, and the purpose is to sink all the opponent's balls first to eliminate the other players.

See also wired.

This is a game played with the same balls and similar scoring methods of carom, but with pockets on the table, and more scoring opportunities awarded when certain balls are sunk in combination.
