When the app starts, pick how many balls you would like to start out with and touch/click the OK button. Touch or click anywhere on the screen to launch a ball down the maze. You earn additional balls if you hit any of the award targets. Easy targets award 2 balls and harder targets award 5 or 10 balls. Try not to run out of balls or the game is over. If you run out of balls, simply touch/click the reset button in the lower left-hand corner to begin again.
