Pool, also more formally known as pocket billiards , is the family of cue sports and games played on a pool table having six receptacles called pockets along the rails, into which balls are deposited as the main goal of play.
There are different billiards games that use the 15-ball set. Eight-ball is probably the standard. Fifteen-ball is a game where shooters play for points and scratches make for a dramatic turn of the tables. The game is also sometimes called 61-pool for the number of points that determines the winner.
This is a variation on that game in which special rules apply to the 1-ball and the 15-ball. The 1-ball and the 15-ball are termed "special balls" in this game.
