This is a very creative and simple game.
Different circles appear in different level of the game, and tiny polygons will also appear when you touch the circles.
Levels completed only when the specified quantities of polygons around the circle.
The only thing need to be pay attention is that, the direction of movement of the polygons maybe different, also the circles will move.More better than hyspherical is quite a interesting challenge.
Although there are many levels to challenge, but levels will be completed if you use your fingers and your head.
