Championship Pool is a pool game where players can participate in 8-ball or 9-ball tournaments that start off with the BCA Regional Championship. The player must defeat 32 opponents in a first-to-four games match, and if they lose, they are then eliminated from the tournament. The winner of that goes onto the World Championship. All of the gameplay is done from a top-down view of the table.
The player moves an icon to indicate where they want to hit the ball to. To aid in aiming, a ghost of the cue ball and the first ball that is hit are repeatedly played out to show the path of the hit ball. With all the shots, there is a very small margin of error, but this only becomes notable when a long shot or a shot from a sharp angle is played.
The player can also change the power and spin of the played shot, with the ghost balls updating to show the outcome of those changes. There are four different game modes that can be chosen, each with a different set of pool games: Tournament, Challenge, Party, and Freestyle.
