About: One-cushion billiards

One-cushion billiards is a carom billiards discipline generally played on a cloth-covered, 10-by-5-foot (3.0 m × 1.5 m), pocketless billiard table with two cue balls and a third red-colored ball. In a one-cushion shot, the cue ball caroms off both object balls with at least one rail being struck before the hit on the second object ball. The object of the game is to score up to an agreed upon number of cushion caroms, with one point being awarded for each successfully made. If no object ball is contacted, one point is deducted. If there is ambiguity as to whether the second ball was contacted, it is resolved against the shooter. It is governed by the Union Mondiale de Billard, the world governing body of carom billiards.
