8 Ball Pool Timer and Rules is a pool game with an amazing physics engine and realistic ball-rack behavior. It also has a 60-second timer, which can provide a warning at 30 seconds. The main area of the screen can be clicked to reset the timer, which vibrates to indicate that the timer has been reset. This makes it easy to time shots without having to look away from the table!
The entire main area of the screen can be clicked to show the current state of the game. It shows how to correctly rack the balls before the frame starts and can (optionally) assist in making the correct ruling following a break or time foul.
