This is a 9 ball pool game for 1 player. You need to pot all balls on the table as quickly as possible following a certain order. You start with the lowest value ball which is the yellow one. The exact order is shown in the bottom of the screen. If you pot the balls in this order, you get bonus, but if you don't, it's still OK. You just need to touch the current ball first when you're hitting. Otherwise it would be a fault.
