The Ancient Game of Awale
This page has the most tenuous and irrelevant connection to the stones of Rombald's Moor - but what's wrong with a little diversion via my memories of living in Senegal.
The game of Awale (or Awele, Ajwa, Lela, Chisolo, Kalak, Oware, Coo, Coro Bawo, Nocholokoto, Dara, Congkak, Mancala, Bawo, Omweeso, Adita-ta, Kasonko, Layo, Gilberta, Schach, Wari, Walle ...) is one of the most ancient games still played. It seems to have come from Ethiopia, and to have spread gradually to all of Africa. The Masai say that the Awale was invented by Sindillo, the son of the first man, Maitoumbe, and was originally called geshe.
Awale is a "plank game" (mancala), played on a hollowed wood plank or with holes "howked out of" the sand, and some stones or seeds. Versions, played to different rules, can be found today in almost every African region and much further afield - in Surinam, Barbados, France, Borneo, India at least.
You can download an excellent shareware version of Awale for Windows or Macs; or there's a listing of different resources on this family of games by following this link. Go on - have a go; and then get yourself a proper Awale board and spread the word.
