The game terminates if you either fail to pot a coloured ball, or if you scratch the cue ball (pot it into a hole) without having any cue balls left.
When you open the game, you are greeted with a cue, a white cue ball, and a red ball. The red ball will spawn near the mouth of a hole. To shoot, pull back on any part of the screen, and release. A longer pull will result in more power on the cue ball. In the beginning, the game has no aim assist, and has only one coin per hole. Potting a coloured ball into a designated hole will give you the coins surrounding that particular hole, and will clear all coins from that hole.
