Ten Ball is a modern pool game. It is a rotation game very similar to nine ball, but more difficult, using ten balls instead of nine, and with the 10 ball instead of the 9 as the money ball .

Ten ball is preferred over nine ball by some professionals as a more challenging discipline than nine ball, because it is slightly harder to pocket any balls on the break shot with the more crowded rack, the initial shooter cannot instantly win the game by pocketing the 10 on the break, all shots must be called, and performing a string of break and runs on successive racks is statistically more difficult to achieve.

Although the game has existed for a long time, its popularity has risen in recent years 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). The World Pool billiard Association (WPA) World Standardized Rules for ten ball are very similar to those for nine ball, but with key changes to ensure the difficulty of the game and its marketability as an alternative to nine ball.
