Color the different world maps, with only 4 colors at your disposal!
Color all the countries across the continents of the world, keeping in mind that countries sharing a border cannot have the same color. It is theoretically possible to color any map with only 4 colors, are you up for verifying this?
And if you succeed to complete the maps, try the extra difficulty levels, what if the order in which to color the countries were imposed? How long will you need to complete the maps?
The map of the north american states is particularly challenging, give it a try!
GreyWorld is a game by BassetSoft.
