Mankka, a mancala game, was invented by the Canadian Kent Barker in December of 1975. It is based on native games of Africa, most notably Oware. The game was marketed by Copp Clark Company in Toronto, Canada. There are two variants; the rules that are provided first are for playing the more sophisticated game (Mankka Two). It can be considered a multiple lap version of Oware, but with a different initial position and capturing on both sides.
