Ten-ball is a rotation pool game similar to nine-ball, but using ten balls instead of nine, and with the 10 ball instead of the 9 as the "money ball" Although the game has existed for since the early 1960s, its popularity has risen since the early 2000s as a result of concerns that nine-ball has suffered as a result of flaws in its fundamental structure, particularly the ease with which players can often make balls from the break.
