Rollick Gaming Platform and Rollick App are outcomes of the G4M (Games for Marketing) pilot project funded trough the Smart Specialization Strategy programme by the Region of Crete (RIS3Crete), Greece. A project aiming to explore how pervasive games and gamification techniques can be employed by companies and other organizations (especially the small ones) for marketing reasons. There are various primitives that can be employed by Rollick games to this direction from just directing players to specific areas, to letting them win real world offers as gaming rewards. Rollick games can even establish their own virtual market allowing players to trade or redeem their assets (collected objects, skills, etc.) getting paid in the game’s virtual in-game currency. Although Rollick was built with marketing in mind, it is up to you what feature you will employ to build your games. Thus, you can use Rollick to create games for educational, recreational, cultural or other purposes! Enjoy it!
