Collect Rings
In this game the game screen is full of squares. From the bottom of the game will shoot a white ball that will move through the squares. With each passing over the squares they will change color. When the ball passes five times over the square it will turn into a ball. Click that ball to get a ring, Click the ring to collect it. If the white ball collides with the new red balls, the game is over. So try to collect more rings before that happens.
