Omweso, sometimes shortened to Mweso or spelled Mweisho, is the national mancala game of Uganda. The name "Omweso" is derived from the Swahili word michezo, which means "game". The game was supposedly introduced by the Bachwezi people of the ancient Bunyoro-kitara empire of Uganda in the 16th century. The okwesa ritual, which included a game of Omweso, was part of the crowning ceremony on the sacred Buddo hill. This ritual was probably as old as the kingdom itself founded by Kintu Kato more than 600 years ago.
