Using spin

Spin can help you better position the cue ball after youve taken a shot, setting you up for your next one. You can also use it to snooker your opponent or stop you from potting the cue ball on your turn.
You can put spin on the ball by moving the red symbol on the cue ball with your mouse or using the arrow keys. That will cause the ball to spin in that direction after its hit a ball.
On Mobile, all you need to do is tap the cue ball in the top right of the screen and move the red circle to apply spin in that direction.
