Radius Ball is a shooter puzzle game. There will be eight dots arranged in a circle. At the beginning of the game a red ball will rotate around one of the dots and at another dot a red ring will appear around it and your task will be to hit the ring with the red ball. If you do, the ring will move to a new location and you will need to hit it again. If you miss the ring, the game is over. The red ball will rotate all time around white dots, so you need to shoot at right time and at right angle.
