British pocket-billiards game in which 15 red balls are arranged in a pyramid formation to begin. Players use a white cue ball in attempting to pocket the reds, scoring one point for each; the player who scores the highest number of pocketed balls is the winner. Players lose a point and respot a red ball each time they pocket the cue ball or fail to contact a red ball. A player shoots until he fails to pocket a ball, and an opponent then continues play from the point at which the cue ball comes to rest. Pyramids was a forerunner of the game snooker.
