Tchouba (anglicized Tshuba) is a mancala game played by the Thonga in Inhambane and by the Chopi in Zavala, Mozambique. It is the largest mancala game so far described, larger than Mefuvha and Nsolo. The game is played with the seeds of the marula tree (Scelocarya caffra) or nickernuts. The game was first described by the Swiss Protestant missionary and anthropologist Henri Alexandre Junod in 1898. A more complete description was given by Elísio Romariz Santos Silva in 1995.
