Owani, a mancala game closely related to Oware and Songo Ewondo, is played by the Obamba, Bateke and other ethnic groups in Haut-Ogooué Provinve of Gabon and also in the neighboring Republic of the Congo (not to be confused with the Democratic Republic of the Congo, once also known as Zaire). Two different rulesets were described: the first one in 1990 by Bonaventure Mve-Ondo of the Omar Bongo University in Libreville and a second one in 2000 by the Fédération AFRIC’IMPACT in Grenoble, France. The former description moves Owani even closer to Oware, while the latter mentions a special rule, which makes the game rather unusual. Both authors made numerous counting mistakes in their descriptions.
