Just Four Colors: free puzzle game for ipad, iphone

Just Four Colors is based on an old math theorem: any map can be colored using just 4 colors so that no 2 neighboring countries have the same color.

We've seen this on the app store a few times.  Quartzic is another title.

There are 10 free puzzle levels.  After that, you must pay.

    Some of those easy levels are so easy I was able to color them with 3 colors! I would hope the harder levels are not based on a Cartesian grid, as it would be interesting to use curved lines as borders.

    Tomorrow I'll post a review of a similar puzzle that will have curved lines.
