GPS game is based on true story and it takes place in historical part of Příbram, on actual places associated with the story.

Imagine you are students of Year 6 A of Příbram Gymnázium (Grammar School). In dark times the classmates come together, the school is a refuge in restless world. Antonín (Tonda) Stočes, your class-mate, a keen sportsman, a good friend, slightly rebellious type, has been absent from school for a few days. The circumstances grow suspicious, so you decide to find out what is going on yourselves...

This game works offline. You'll be navigated to waypoints in Příbram's Old Town using your compass and distance gauge. Individual tasks will pop out at waypoints and you will be awarded with a digit fitting the final coordinates upon successful solution. Final coordinates will lead you to a place where the pieces will complete the puzzle and you will find out what happened to Tonda...

What is more, this game acts as a guide through the history of the city's most prominent places and landmarks. The app was devised as a student project work within Erasmus+.

All the tasks can be completed only during the opening hours of the Holy Mountain Stairway:
