I have an Android implementation of this ancient game. The link will download and offer to install it. Because it is not (yet) on the Play Store, you will have to enable ‘unapproved’ software installations.

Owari is a bead game played all across Africa. It has many spellings, more common variants being Awale, and Warri. It is from the Mancala class of games, which are count and capture bead games, with many different variations of rules. This variant is the one played by the old men in market places in Lome, Ghana, and other parts of West Africa. It is rumoured that it was to be played by kings to prove their strategic skills on accession to the throne in Ghana.
