Why is Crystalix one of the most popular logic games? Perhaps it’s the addictive gameplay, which challenges you to cleanse a devastated land of the remains of a shattered comet. To clear away the cosmic debris, you must place different shapes that scroll along the bottom of the screen over stacks of matching gems. Special powerups are on hand to aid in this task. One helpful bonus is the wand, which allows you to remove troublesome pieces of the comet without matching them with an available shape. Begin the journey of logic and reason that has enchanted so many others before you.
