Almost every child's game and toy on the market claims to have some educational merit and most of the time it's dubious at best -- so-and-so teaches "cause and effect", "pattern recognition", etc. -- like some silly educational blurb that pop-ups before some inane cartoon on Noggin.
I won't go into what this game is about -- the product summary states that clearly. I will say is that this game will teach strategy to your 3 or 4 year old. It creeps into your child so nonchalantly they don't know it's happening. That's because they can just begin playing, even if they do everything wrong from the get-go, without some dissertation or prelude parents feel compelled to deliver before teaching, say, checkers. I enjoyed watching my 3 year old intentionally slide the tiles in a way that would benefit her and screw me.
Don't get me wrong, this isn't the best game on the planet, just a good kids game. Kid-Cala, a derivative of man-cala is also excellent. My daughter doesn't want to play it every night but she goes through spurts. It's a short game, which I appreciate given her attention span -- it takes ~15 minutes to complete a game.
It's well constructed from heavy-gauge cardboard, typical of Ravensburger quality but it's not perfect. There is a bump on the game board where it folds and it often acts as a road block when sliding the tiles. I help keep the tiles from sliding over/under one another when my daughter pushes them.
I'm glad I purchased this.
