Rings.

Rings. The first and original. Arrange them, stack them, match them. Can you clear the board? FOUR WAYS TO PLAY: Classic - nine slots, no clock. The only mode the leaderboard is watching. Double Diamond - thirteen slots and new lines to complete. More room, more ways to go wrong. Time Trial - thirty-six seconds. Every clear buys you two more. One Ring - one piece at a time instead of three. Nowhere to hide. Complete a line and your multiplier grows. Land a Full Stack and it grows again.
