Pool
Pool originiated in the 1840's in the USA as the American form of pocket billiards. 8-Ball Pool was invented around 1900: one player shoots the low balls, numbered 1 thru 7, which are represented by solid colors, and the other shoots the high balls; once a player has made all seven of his balls, he or she can sink the eight ball to win the game; a player can also win by sinking the eight ball on the break, or lose by sinking the eight ball out of turn. 9-Ball originiated as a gambling game around 1920: only nine of the 15 balls are used and the object is to sink the 9-Ball; the cue ball must first hit the lowest-numbered ball on the table, but the nine ball is often pocketed early either on a carom or on a combination shot off the original object ball.
