What is "hawalis"

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).
