GEOFUN is an elaborate mobile application for smartphones, which guides you through the most interesting places in the Czech Republic in a fun and competitive way. The game is based on the popular geocaching, but it much more exciting and adventurous in character. Basically it is a fun geolocation game of the new generation, where it is not enough to just find the place and check yourself, but you also have to perform various assignments that the guide assigns you throughout the game. Your guide is always someone local who knows the given city or region well and can give you good advice.
During this time you can play in Prague and Karlovy Vary.
