1816:L'énigme app for iPhone and iPad

As part of the bicentenary celebrations, the BCGE is making a mobile application (“app”) available to the general public from Friday 1st July 2016 to Sunday 28 August 2016. This app will allow all those who download it to take part in a puzzle-style game about the history of the BCGE throughout the City of Geneva. The game involves having to go to different sites in the city, guided by clues proposed by the mobile application. There are 8 locations to be identified; each one can be discovered with the help of 2 clues.

Site identification is confirmed with the help of beacon technology and the GPS of the players’ mobile phone. Various beacons, installed on the sites to be identified throughout the City, can be discovered using the mobile application which detects the presence of these beacons by means of Bluetooth technology. In some cases, where it was not possible to install a beacon, the mobile application uses the GPS to locate the sites. When the players get close to the site being targeted, their telephone screen will signal the finding.

You need a device supporting "Bluetooth Low Energy" (iPhone 4S minimum) to interact with beacons.
