Crystalix offers a unique blend of logic and arcade action. In Crystalix, you're a wizard who sets out to cleanse his land of the remains of a shattered comet. To clear away bits of the cosmic debris, you must place game pieces of different colors and shapes over matching stacks of gems. New game pieces roll across the bottom of the screen and will start to accumulate if they're not used. A quick hand is helpful, but you should also plan ahead if you want to clear away all of the pieces of the comet.
