Krur (Crur) is a mancala game, which is played by Hassaniya speaking people in Western Sahara, Morocco and in Mauretania. It is mostly played by children. The holes called dyar ("houses") are usually dug in the sand. The game was first described by C. Béart in 1955 (Mauretania), and then again in 1999 by Fernando Pinto Cebrián (Western Sahara). It may be related to Um Laarais.
