Le magicien remplaçant

A magician has found a cryptex (small safe) and must find the code to open it. Inside the cryptex is an important message to deliver to the children. Unfortunately, the magician cannot be present today. He therefore sends his substitute with a series of riddles to solve in order to find the word that will open the cryptex. The substitute will need the children's help, and each magic trick brings you a little closer to the solution.
