This is a 3D variant of pool billiards game. You don't have an opponent, but play against time. Your goal is to pocket all balls before the time is over. Click and drag in front of the cue ball to change the direction of the strike. Click on the cue ball and drag downwards to adjust the power. Release to strike. In the top left corner of the screen you'll see the ball that will give you extra time if you pocket it. Try to pocket it first.
