The events of the Vaino series are adventure boffering events where participants survive a weekend in the forest and compete to find the legendary Sampo. The game is set in a Kalevala-inspired borderland, where various clans and other parties seek to gain control of the Sampo. Players' skills, cunning, and trust in each other are pushed to their limits as they have to survive against the world and other players.
