9-Ball challenge where you have to pocket as many balls as you can in under 3 minutes. You can control the angle, power and even how much "English" you want to apply to your shot. A nice feature is the line of sight finder, which can help you determine the trajectory of your cue ball.
Mouse: Use your mouse to setup the angle, power and english you want to apply to your cue ball. Click and drag the mouse to setup the power. Release the button to hit your cue ball.
