Great confusion for young and old. Bought it my 4.5 years old son needed. Therefore, I can say - durability OK - nothing to complain about. It is a difficult form of memory, because you have to find the color of water lily on the underside of the respective frogs. After two or three rounds you do as an adult often not where the matching is executed frog jumps. So you have to really concentrate, so as not to lose to the "little ones". It's all great fun, but you can not play a long time, since it is quite tiring in the long run.
