Quartzic: great free iphone ipad puzzle app
The object of Quartzic is to color the map (squares and rectangles) with only 4 colors such that, no 2 adjacent countries have the same color. This is based on a classic math theorem, which may or may not have been proved, I'm not sure.
There are 60 puzzles. Some puzzle levels require using blue or red a limited number of times; this complicates things! I am stuck on level 15. Without a doubt, this a challenging, fun game and is one of the best puzzle apps of 2012! Martin Roberts is the author - excellent job!
