Nice Present
A bit of form over function. Once it's done it's done and the value lies in how long it takes - in this case took a while for the 11 yr old who it was given to to crack it, but the presentation's great, so was a good present in all...

Entertaining
Bought for my Great Nephew, but kept the rest of the family entertained too trying to solve it. Made of wood so more sustainable than plastic which is a bonus.

Foi pena não me ter apercebido que a dificuldade é de 2 em 5. Pensei que era um quebra cabeças mais difícil. Fora esse aspeto é 5estrelas.

Bonne idée cadeau. Niveau pas trop difficile/ réalisable pour enfants curieux...
