En Dodoi (plural: En Dodo) is a mancala game, which is played by the Loitha and Kisonga Masai in northern Tanzania. The Masai use about two feet long wooden boards and the seeds of Caesalpinia bonduc as counters. It is usually played by boys, rarely by warriors who prefer En Gehé and never by women. The first European to describe En Gehé was the German Moritz Merker (1867-1908) of the Imperial Protection Troops (Kaiserliche Schutztruppe) of German East Africa in 1904. He is also regarded to be the first ethnologue of the Masai.
