ThinkFun Izzi Puzzle - Builds Thinking Skills Through Fun Gameplay

We bought this for our nearly 6-year old (the pack says 8+) who loves puzzles. There are 64 pieces. There is just one rule - the edges must match. Doing all 64 pieces (to make an 8x8 square) was quite tricky even for us adults. So, it was understandably difficult for a 6 year-old. So, we modified the rules by asking the kid to first try a 4x4, then graduate to a 5x5. At 6 years old, she managed a 6x6 with ease; 7x7 was trickier... this is a puzzle that will grow with age. Worth the buy. We have bought other stuff from Thinkfun and they have all been very educational so far. They are also made from good quality materials.

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.

Excellent puzzle. I used it as a teacher and now my 5 year old grandsons are fascinated. They do a 6 by 6 square which usually works out. My only gripe is the price. I see that it's $6 in USA but between £30 and £70! to get it here! !

Exactly as described just a bit confusing on how to do it but well worth the money

Surprisingly fun. Even our oldest soon (7) likes to play it by himself. Paid around 4$ for it. Definitely worth it at that price. Think of it as single player Blokus.
