10 Ball is similar to 9 Ball but with 10 balls and an additional requirement: each ball must be called before being pocketed.
1
Rack
10 balls in a triangle. Ball 1 at the top, ball 10 in the center.
2
Called shot
Each ball must be called (ball + intended pocket) before the shot. Combinations must also be called.
3
Contact rule
The cue ball must always contact the lowest-numbered ball on the table first.
4
Fouls
On a foul, the incoming player has ball-in-hand but only in the bottom half of the table (unlike 9 Ball where the whole table is used).
5
Winning
The player who legally pockets the 10-ball (after calling it) wins the game.
