How many balls are needed to play a standard game of pool?

Pool is played on a pocket billiard table with one white cue ball and 15 numbered object balls. Two individuals, pairs, or teams can play. Points are scored for pocketing designated balls in designated pockets. The first player or side to reach an agreed number of points wins the game. A set of pool balls consists of 16 balls: 1 white cue ball and 15 color-coded numbered balls. The balls numbered 1 through 8 have solid colors, and the balls numbered 9 through 15 are white with a center band of color.
