Songo Douala (also spelled Songo Duala in English, Portuguese and Spanish literature) is a regional variation of Songo Ewondo played by the Douala people in Cameroon. The game was first described by Major P. H. G. Powell-Cotton in 1931. Harold James Ruthven Murray wrongly stated that the game is played on a 2x6 board (according to Powell-Cotton it has 2x7 pits) and Elísio Romariz Santos Silvain copied this error in his Ph.D. thesis about mancala games although he pretended to have read Powell-Cotton's article. Later Jordi Climent Tondo added several more mistakes such as counterclockwise play (clockwise is correct) and captures on either side of the board (in fact, it can only be captured on the opponent's side).
