Le magicien remplaçant

A magician has discovered a cryptex (a small safe) and must find the code to open it. Inside the cryptex is an important message to be delivered to the children. Unfortunately, the magician cannot be here today. So he 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 will bring you a little closer to the solution.
