In Kancha Returns there are two sides to the game: the red side and the blue side. You are the blue side. Click on the ball you want to shoot and hold down the mouse button and drag it back to get the direction you want to shoot it in. Don't shoot too hard, because if you shoot your own balls out of the screen that counts against you and for the red team. Try your best to get as many balls out of screen with each single shot. As the levels go on the configurations you start in will be different. You'll find new challenges with each level in Kancha Returns.
