Your main goal here is to build complete set of 4 rings by dragging rings around the board. Rings can be placed on top of larger rings, or in an empty cell. A new ring appears in the center cell and after a few seconds, it moves toward a neighboring cell. Click the center cell or press space bar to move the ring without waiting.
The game immediately ends when a new ring moves on top of a smaller ring.
Each complete set of 4 rings increases your bonus bar. Fill the bar completely to enter the Powerzone, where you get extra points for 30 seconds.
