The screen fills up with candy colored viruses, and your job is to make them disappear. How? Tapping three of them with the stylus makes a triangle, and tapping any point you’ve connected again zaps them out of existence. Let them sit too long, and they’ll congeal to stone. Also, failure to connect tap-activated viruses or to make that last click and make them disappear causes them to instead congeal even faster, and they’ll clutter up the screen, as they can’t be used as a starting point for triangulation.
But, trapping a congealed virus within a triangle reactivates it, and it can then be linked to two other "virii" (hey, it could be right) of corresponding color for a chain combo. At first, we were playing a little too Hexic-minded; making close, tight triangles for a dismal Puchi performance. But once we started utilizing the entire screen, the combos really came alive. Drawing a larger triangle activates any virus within it, congealed or not, leading to incredibly satisfying combo chains. Tap your initial triangle to kill it, and any other triangle within it will be activated, then any triangle within that one, etc.
