Encoded treasure hunt

For the birthday party of my eldest, I prepared a special treasure hunt with encoded messages that they had to decipher to get the next clue. For every boy I made an encoding disk and explained them the technique of encoding by alphabet displacement. They had been occupied quite a while with decoding, following the clues and running through the village until they found the key for the safe.



A bientôt,
Jane
