色の障害物を介してボールを渡り。ボールが間違った色を打つべきではありません!
Tap timely to make the ball cross color obstacles. Be careful with your taps as the ball can only pass through the obstacles at the same color as its own. As you move up, ball changes colors. So always stay conscious of the color your ball currently has. You lose if the ball hits any other color than its own!
