The concept

Duration: 2h30 - From 5 people - From 8 years old

This game of code takes you on a tour of Old Lyon. Your objective? Solve riddles to decipher a mysterious code! The game of code is like a treasure hunt. You'll have to solve riddles, complete missions and be constantly on the lookout for the slightest clue. You'll have to submit to the missions of your liaison agent (the game master).

How does it work?

  • At the start of the investigation, your game master will give you a code that you'll have to decipher.
  • You'll have to scrutinize and analyze every detail, and pay close attention to everything you see, to perhaps find a clue to your investigation.

Dive into a more confidential and esoteric Lyon, and unlock the secrets of Nicolas Flamel and the other mages and alchemists of Lyon to succeed in their quest.
