This is an African Board game commonly played in West Africa. The board has 2 rows of 6 holes. In this version each player owns one of the two rows and may select any hole to move. The game starts with 4 stones in each hole. Play alternates between the players each taking a turn. In a turn a player selects one of the 6 holes in the row closest to him. He removes all the stones, and places them, one each, in successive holes starting with the hole to the right of the one just selected and working counterclockwise around the "circle". For our purposes the 12 holes make a "circle".
If the final stone is placed on an empty hole the players turn terminates. If it terminated on the land owned by the player, the player wins the stones across at the opponents row. This is the birth of the cow and is the only means of winning. The game ends when there are less than 4 stones left in which case each player keeps stones on their territory. Simply chose who starts and run the game
