[This review was collected as part of a promotion.] This game requires a lot of patience, which my son needed because it requires a lot of time, it is a good entertainment game, it develops de-stressing skills, personally I didn't like it very much because it is very complicated to put together and requires a lot of investment. time and if children are not patient it causes despair and they get bored quickly, the material is designed for children over 8 years old due to the small pieces it contains but a child of 6 or older can participate in the activity as long as they are supervised by a adult.
