Main countries are Russia and ex-USSR countries, Nederlands, France, Belgium, Poland, Ivory Coast, Senegal and Congo. But some good players are in Brazil, Israel, USA, and Italy too.
Double corner is on the right of each player.
The men can move on each square forward left and forward right if it is empty. When they arrive on the last line, and stop on it, they become kings. The kings can move on all the squares which are on the 2 diagonals that cross where they are, if there is no piece between them and the arrival square. Captures Maximum captures are compulsory. If they can jump again from the arrival square, they must continue the capture.
