Crazy Pool is a pool like game where you try to get the same colored balls hit each other. There is a certain time limit to each level and you must make all the ball disappear before the time is up. Each level takes only a minute, so it is very easy to keep on playing this for 15 or 20 minutes after you told yourself to stop, if you are into that kind of game.
The highest level that I have finished is 20 with a total score of 3545. Common, give it a try.
