Drag rings around the board to make complete ring sets. Rings must be placed on top of larger rings, or in an empty cell.

New rings appear in the center and need to be moved into a random cell. Click the center cell or hit the space to drop the ring without waiting.

To pass a level you need to compete a certain number of ring sets.

The game ends when a new ring moves on top of a smaller ring. It's up to you to reorganise the board so that never happens.

Each ringset you complete will increase your bonus bar. Fill the bar completely to enter powerzone, where you get extra points for 30 seconds.
