Your objective in this highly addictive game is to use bouncing balls to clear all the notes on a stage. Each level has a maximum amount of ball gates you can open. The trick is to find which gates to open and at what times. Use YOUR MOUSE to click on a number gate to release a ball from that gate. The number on the gate shows the beat on which the ball leaves the gate. Each level has a maximum amount of gates that can be opened. A ball must hit a block once in order for it to be clear (twice for dark-colored blocks). When a block is hit, a loading bar appears where it was. Once 8 beats have passed, the block will reappear. Good luck!
