Sri Lankan 12x12 checkers are only played .... in Sri Lanka.
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.
The rules
This game is played on a 12x12 board (144 squares).
Double corner is on the left of each player.
Moves of the men
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.
Move of the 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. That means that if you can capture 2 pieces with a piece (man or king), and 3 with another one, you must choose the 3 pieces capture.
Capture by the men
The men can capture forward and backward, by jumping over 1 opponent piece (man or king), if the piece is near it, and the following square is empty. If they can jump again from the arrival square, they must continue the capture.
Capture by a king
The king can capture a piece if it is on the same diagonal than it, if there are only empty squares between them, and if the following square is empty. It can stop on whatever square on the same line. If a new capture is possible from one of these squares, it must continue the capture.
Who wins, who loses ?
The loser is the one who cannot move any more (no piece or all pieces blocked). The winner is his opponent, of course.
There may be draw if :
-opponents agree for a draw
- the same position is encountered 3 times
- there are 3 kings against 1, and each played has played 16 moves without any capture or promotion.
