Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
Mr. Shumway: I think the idea is good, but it would probably be a little difficult for the "creator" to come up with those probabilities. If they are automatically made by a poll, that would make it easier. I am guessing it would be a lot of implementing to do on Fencers part though :(
My suggestion to make the random games more interesting, is that when you create say a "five match random game", that you actually do get five times a different game. It would probably "ruin" the statistics department, but a special slot could be opened just for "random games"... or just make random-games not affect BKR.
