Blackball is a cue sport similar to pool, played on a rectangular table with six pockets. The game involves two types of balls: solid-colored balls (1-7) and striped balls (9-15), plus the black 8-ball. Players take turns trying to pocket their designated group of balls, either solids or stripes, using a cue stick. The objective is to pocket all the balls in their group and then legally pot the 8-ball to win. The game requires precision, strategy, and control of the cue ball for successful play.
