How Morabaraba relates

Morabaraba is the mill game of South Africa, Lesotho and Botswana, known in isiZulu as umlabalaba and in Setswana-speaking communities as mmela. English-language references call it Twelve Men’s Morris. It keeps the Nine Men’s Morris board, adds diagonal lines through the corners, and gives each player twelve pieces.

The pieces are spoken of as cows (dikgomo), each player keeps a herd, and the board echoes a cattle kraal seen from above. With twelve cows a side, a placement phase with no captures fills all 24 points, so the opening is tighter than in the nine-piece game. More in Morabaraba vs Nine Men’s Morris: what’s different.
