Shooting: Touch or click anywhere on the table and drag away from where you want the cue ball to go — like pulling back a slingshot. The farther you pull, the harder the shot. Release to shoot. Pull only a tiny bit and release to cancel.
Rules (Simplified 9-Ball)
The cue ball must first hit the lowest-numbered ball on the table, or it's a foul.
If you pocket a ball without fouling, you shoot again.
Pocketing the cue ball (a scratch) is a foul. Your opponent gets ball in hand and may place the cue ball anywhere.
Failing to hit any ball is also a foul.
Legally pocket the 9-ball to win.
If the 9-ball drops on a foul, it is re-spotted and the foul stands.
