Four Colors Challenge

Four Colors Suffice,a fantastic anti-Elimination puzzle game.

The four color theorem,one of the world's three mathematical conjectures, states that, given any separation of a plane into contiguous regions, producing a figure called a map, no more than four colors are required to color the regions of the map so that two adjacent regions WOULD NOT BE THE SAME. Two regions are adjacent if they share a common boundary that is not a corner, in which corners are the points shared by three or more regions.It was proven in 1976 by Kenneth Appel and Wolfgang Haken and by computer as the first major theorem.Now, it's time to prove this theorem yourself! Let your logical thinking to get an incredible workout!
