Hawalis is a traditional mancala game played in Oman as well as Zanzibar, where it is known as Bao la Kiarabu, with slightly different rules.
It is closely related to African mancalas such as Bao (Tanzania, Malawi, Kenya), Njomba (Mozambique and Malawi), Lela (DR Congo), Mulabalaba (Zambia), Muvalavala (Angola) and Tschuba (South Africa, Mozambique).
At his or her turn, the player takes all seeds from a hole and relay-sows them counterclockwise.
If both the opposite hole and that behind it in the opponent's half board are non empty, all seeds are captured from both of them.
The rules of Bao la Kiarabu were originally transcribed by W. H. Ingrams, who described two variants of the game.
