Secret Box: Black Tortoise

Black Tortoise is a puzzle from the Secret Box collection. Originally, these boxes were used to hide objects, money or important notes. It’s a very nice gift idea! Slip a coin or word inside, then offer the box. It will be necessary to succeed in opening the box to discover what it contains.

Each secret box has a unique mechanism that must be decrypted in order to be able to open it. A slot on the side allows it to be used as a piggy bank. The difficulty is adapted to suit the whole family and amuse young and old.
