My son got this game with 6. He plays it very much. Initially there was the guide, although very simple, a little hard for him to understand. Since you have already noticed that it is not so easy for the little ones, sew together the monsters correctly. Six months later, with the start of primary school it works and he plays it like. A great support for math lessons. The little monsters are given after the game in the white box, the manual is in place and is stored in a closet, the cardboard box is no longer needed.
