Mangue... I just woke up and am having a hard time picturing what you are saying..
I personally have never had a draw in any Halma game, and don't really see how it would be ever possible. (Unless it's just a decision between the 2 players.)
If you look here, you will see that at brainking only .2% or so of the halma 10x10 games have ended in draw.
It is important to remember that it is NOT a requirement to jump... so there is ALWAYS a move available..
