The Wall Games Code Breaker challenge is a free to enter, interactive game taking place across Northampton Town Centre.

There is a QR code at each of the Wall Games locations listed on the map.
Navigate to the locations using the what3words app and then hunt for the QR code

Once at the location, using the camera on your phone, find and scan the QR code to reveal a letter and write this down. Once you have visited all the locations and collected all the letters, rearrange them to reveal the name of the final location. Head there to complete the challenge!
