To play the game, use your mouse to aim your billiard cue and click and drag to set the power of your shot. Release the mouse button to take your shot. If you see arrow icons around the cue ball, this means you can click and drag on the ball to move it. This feature is only available when you're breaking or when your opponent commits a foul. To adjust the spin of the cue ball, click on the cue ball icon at the top of the game screen. This can help you set up trick shots or give you more control over the ball's movement on the table. Good luck!
