The concept here is very simple: use all of the cardboard squares to make a square puzzle in which all touching pieces only touch other pieces of the same shade. i.e. white touches white; black touches black. A simple idea and to begin with it is very simple - another multi-age friendly game. Towards the end, things get tricker and you have to swap pieces in and out in order to complete your square. Once you've managed to complete the first square, there are variations using shapes to make the challenge more devilish - I've not attempts those yet as its still a new-ish purchase but it means the game has longevity. My only criticism would be that the pieces are cardboard - given the usual quality of ThinkFun's games, I'm surprised the playing pieces weren't made of some sort of plastic to make them more durable and resistant to damage.

Although this can be done as a solitary activity, my son and I have sat a few times to attempt it together. You think you're making great progress and then there is a final piece that doesn't fit, so keep trying! It's good fun, a very simple concept, inexpensive and portable.
