We have the puzzle at the pediatrician and on site, but in both there is not even together so much to discover as in this application. Our son (4) always needs new challenges in Puzzle and particularly likes TipToi puzzle. With this we have hit the jackpot. The puzzle have just the right difficulty for our son, not too light and not too heavy and the puzzle itself, there are soo much to discover .. The games are then the highlight, it must be helped to the ambulance service, the fire brigade or the police. For the rescue service he has now been used for a while, from time to time came sometimes a "Mom can you ever help me please", this much can be explained in this puzzle yourself and you will not so often "hang" far as .. at the other games Even I'm in between the search and it's really fun when it's a bit trickier :) The theme is simple and super appealing for this age, and I think it's great how the kids internalize the concepts of materials and learn the way what where why needed. I would be more than 5 star awarded if it were possible. Thumbs up, more of it, not beat, especially for the price of less than 11 euros!
