rules as listed at the Minneapolis Institute of Art, where they have the game in their Africa wing(let).... ero and i learned the game there, when we and the cat shared a studio on 1st Ave., a block or so away. the game we later purchased has different rules but we liked these better:
all moves clockwise
3 possible moves
1. "scooping move" -- pick up all seeds and move them one cup left
a. move cannot be used to move seeds into home cup
b. move cannot be used to move seeds into opponent's cup
2. "scattering move" -- pick up all seeds and drop them one by one into cups to the left. you can drop seeds into opponent's cups but not into either home cup
3. "the home move" -- a scattering move that ends in a home cup. this move is rewarded with an extra move. it can be repeated for continued extra move(s)
To win: move all seeds from your playing cups to your home cup before your opponent can do the same.
