Bratislava Hrajsa supports the creation of several different games under one app. The games are created and manged through a custom admin interface and after confirmation, each player can download the game into their device.
After finishing a game, the player gets an automatically generated decree with the level that they accomplished. This is sent as a PDF to a previously supplied email address or alternatively to a place where it can physically picked up. The decree includes the player's name, level achieved with its respective ilustration. Logo and the player's picture which gives the decree a more personal feeling. The decree can also include various discount coupons, tickets and similar rewards meant to motivate the player to visit cultural and other events.
For the player to be bale to answer the game's questions, they have to actually be on the given location. The game uses the device's own GPS to confirm this.
The second option for localizing players that is supported are QR codes that can be scanned by the player to get the next question for the game.
