Swing the ball around with your mouse, and hit the black balls away. Take care though to not allow the white ball of yours to leave the boundry of the level, because if you do, you lose instantly. Keep playing and collect experience points and then spend them on upgrades for yourself - speed, size, ball size, and boundary size. The harder you knock out the opposing balls, the more experience points that you will end up collecting. For each 10 levels that you beat, you will then face off against a boss character. Bosses are much tougher opponents that will take more planning to take out without dying. They have lots more health than usual enemies do, but if you keep at it and keep smashing away at him eventually he will run out of health and you will win and move on to the next level. Seeing as that this game has so many levels to it, a useful feature in this gaem is a save and load function, allowing you to come back and pick things up where you left off at a later point in time.
