A simple, really fun game to play. Addictive yet relaxing and challenging at times. Your goal is to fill with color all regions with no more than four colors. Two regions that have a common border (adjacent) must not get the same color. ● Two modes to play with: Normal and Frenzy ● Simple One-Touch controls ● Addictive yet relaxing gameplay ● Fun and challenging for all ages ● Play at your own pace "The four color theorem is a theorem of mathematics. It says that in any plane surface with regions in it (people think of them as maps), the regions can be colored with no more than four colors. Two regions that have a common border must not get the same color. They are called adjacent (next to each other) if they share a segment of the border, not just a point." (Four color theorem."
