Try to shoot the balls with similar color that are approaching linearly on the track towards the hole. Your aim is to avoid the balls reaching the hole by matching 3 consecutive balls or more of the same color, and making them disappear to reduce the ball counts. You have got 2 power shots. One is for pausing the movement of balls for a short time and another shot can be used for reversing back. You need to be successful in all the 10 levels to win this game.
Use mouse key to aim and shoot.
