From the game box: "Answer the call of the diamond - A new game, to be played on the familiar board of Afrikan Tähti, which will take your adventure to a whole new level!" Afrikan tähti - Retkikunnat is an expansion to Afrikan tähti, the most popular Finnish board game. Actually, it's more like a new game, played using the components of the old game. Instead of hunting directly for the treasure, players must first form a team, finding resources and allies. Once the team is ready, players can start hunting for the big diamond. Finding the big diamond is not the end of it, like in the original game: now it's possible to steal the treasure from another player. Also, players do not start with identical resources: each player has a different character, with special powers.
