Do you know the rules and how this game is played?

I remember being in a group of people, maybe in Tanzania or Malawi (?) at night outside a native pub and one of our group asked the locals to show her how to play. I remember listening but not too well (ie not enough to memorize the rules).

I think it might make a nice thread to put up the rules and a photo of the "board" somewhere on NE.com. Members can amaze their trackers by playing the game with them

.

PS Can you photograph the board? I am sure somewhere on the internet the rules can be found. I saw a modern creation of this game in a shop in Sydney plus about a dozen other 'native' games from around the world.
