I enjoy playing RISK, but I haven't in a while. The other day I came across JRISK and started up again. JRISK is cool because it is open source and it took the most boring part of the game out, the defense. Now with its handy "auto defend" you just have to worry about attacking and strategy, not clicking on the roll button.It has been quite a while since I last played, and I had always wondered what the probabilities of the different die rolls were. Well, one Saturday morning I did a quick calculation and found the probabilities and decided to slap them up on my new web page for everyone to see. (and critique) There is also a spreadsheet with the probabilities.
