Tetris with a twist! (A 360 degree twist!)
This is a fun, fast-paced game that's both an action game and a fascinating puzzle game. Hexagonal gems fall from the outside of a large wheel toward the center. When they touch each other, they stick together and to the wheel. You rotate the wheel to make the gems fall where you want them to. When you build a ring of one color that surrounds the center,
the ring blows up, clearing space for more gems.

An interactive tutorial quickly shows you how to play.
