Layli Goobalay (literally: "closing the holes") is a mancala game played in Somalia. The board is dug in the ground and the pieces are dry camel dung called salo. Slightly different variants of the same game exist, among them a more simple game, which is promoted by the Somali ethnomathematician Jama Musse Jama in Italy. The following rules were observed in 1931 by G. Marin in the area of Berbera, Somaliland, where it was (and probably still is) a favorite pastime of the Isaaq clan.
