Mankalah (also called Warri) is one of the oldest known games originating from Africa. Each players has 7 pits, 6 of them containing stones. The larger bowl to the right is called the Kalah.

The object is to move more stones into your Kalah than your oponent. On each turn a player selects one of his pits to move stones from. All stones are removed from the pit and a single stone is placed in each pit in a counter clockwise direction, skipping your oppponents Kalah. If the last stone lands in your Kalah, you get another turn. If the last stone lands on one of your pits that is empty, and there are stones in your opponents pit directly across from the last pit, both your stone and your opponents stones are moved to your Kalah.
