How to play
1. A red, blue, or yellow ball falls down from the black ring at the top.
2. Long-tap the white ring at the bottom. The ring color will rotate.
3. When the bottom ring color matches the color of the falling ball, remove your finger. The ball will fire upward.
4. If it hits the same color ball, the balls will burst, adding to your score. Destroy many falling balls!
5. If a falling ball hits the white ring at the bottom, the game is over.
Have fun!
