Šalingrad is inspired by the famous detective game Scotland Yard. The principle of the game is simple: a group of detectives moves around the city of Brno using public transports, trying to reveal the movement of the mysterious Baron and catch up with him. The Baron's movement is secret at first, but later reveals its position several times. If the Baron manages to stay untapped for 24 hours, he wins. However, if one of the detectives enters the stop occupied by the Baron, the Baron must appear and admit his defeat.
