They look like Canadian checkers, but the double corner is on left. If you don't mind this point, the rules are the international ones.
Double corner is on the left 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.
