Dubbed Beat the Street, the game has been designed to help get locals from the town active.
UK town Milton Keynes has been transformed into a giant game, which aims to get locals active by collecting points to win prizes.
Dubbed Beat the Street, players can walk, run or cycle around the Buckinghamshire town and use their card to tap on different special sensors located around Milton Keynes in order to track their journey.
More than 100 sensors have been set up as part of MK50, which marks the 50th birthday of the town.
The game, which is provided by Intelligent Health on behalf of Milton Keynes Council will run until March 15th.
