Afrikan tähti is a popular Finnish board game. It was designed by Kari Mannerla. It has been produced since 1951. Afrikan tähti has remained one of the most sold board games in Finland for 65 years. During this time it has been translated to over 16 languages. It is most popular in the Nordic countries, where it became widely marketed in Sweden, Norway and Denmark in 1960. In Sweden the game is called Den Försvunna Diamanten, in Norway Den Forsvunne Diamanten (both meaning "The Lost [or, Vanished] Diamond") and in Denmark Afrikas Stjerne (Star of Africa). In Finland over two million games have been sold, in Sweden and Norway almost one million and in Denmark half a million. There are over 4.5 million sold games internationally. During his retirement years Kari Mannerla revived one of his old creations Inkan Aarre in a completely modified version. Inkan Aarre has sold over 100,000 in Finland.
