As a programming exercise, this is pretty neat. Not, as LizBo says, real practical, though. In English, lots of words exist to break the rules. Dice is one of them> Dice is the plural of die, but only when referring to the ones you roll. So two or more are dice, and one is a die. No dices.

Good, if superfluous, work!

Sorry Joel but this is utter nonsense. This would just slow the overall board game down. No software can pre-determine what the dice rolls will be and anyone with a few brain cells can visually see if they out number a neighboring region to determine if a attack is worthwhile.

Hi. I've created the software not exactly to use it when playing, I was challenged by a friend to create it, and I needed it to evaluate the effect of italian rule (3 dice in defense).
The software cannot determine the dice rolls, but can estimate the probability of the rolls.


If you don't like it, don't use it. I thought it was pretty cool.
