Merge pool balls and score big in Comball. Each ball you can push onto the pool table will appear at the bottom of the board. Click and drag your mouse to set your aim. When you're ready, release the mouse button to push the ball onto the table. Make sure balls of the same number and color merge to create a bigger ball!

There is a meter underneath the ball that will be pushed onto the table. Each time you push a ball onto the table, the meter will decrease by one point. When you successfully merge two balls, the meter will restore one point. If you fail to make any merges, the meter will run out and the game will end.

There are also some Comball power-ups you can use. Click the Shake button in the bottom left corner of the screen to shake the board and make the balls roll. Click the Change Ball button in the bottom right corner of the screen to change the ball that will be pushed onto the board. Each power-up has a limited amount of uses.
