The color of the ball at the bottom right corner defines the player who will shoot his/her ball.
In order to score, the player's ball must hit both of the other two balls. It is not important which one it hits first. If the player makes a score, it is his/her turn again. If the player cannot score, the other player continues.
3 Cushion mode is the same, except that the player's ball must hit the cushions at least three times before it hits the second target ball. It can hit the cushions before or after the first ball, but it must hit any cushion at least three times before it hits the second ball.
