I know we are trialling this, so we expected some hitches but there were quite a few problems. To give examples…the first question is very unclear in regard to which digit of the date is required. The third question requires us to count balusters on a particular level. We counted 9 but the answer is 3. The question should be clearer to refer to only one of the three bannisters if you want to keep that answer. On the fourth question, the map location is wrong meaning we walked past the clues and had to retrace our steps. The last question was the most frustrating. We found the answer but were faced with 10 boxes to complete not one, and had to try and recall all our answers at that point, even though we had filled them in as we went. Even then, some of the digits were not as we recalled them. We gave up at this point. I don’t think this is ready for charging people and I would suggest someone reviews the questions and answers

The mission: Your story in Quebec

An underground network of 18th-century cartographers hid a master logbook containing maps of lost subterranean tunnels. They secured it inside a matrix, scattering a physical 10-digit decryption code across the city's stone monuments and fortresses.

As an archivist, you have intercepted their encrypted radio frequency. Retrace their historic steps from the lower town to the plains, extract the code from the physical architecture, and unlock the final vault.
