dicepro: Ah, so "Knights of Fury" will even be longer than "Knight Fight". ;-)
In Knight Fight, no game can last past 50 half moves - then all the numbers have gone. As I see from you latest proposal (why are game proposals first posted here, then continued elsewhere???), the limit for Knights of Fury is 52 half moves (40 non-grouped numbers, 24 grouped numbers).
Personally, I find the rules still to be inelegant - numbers ending in 7, 8, 9 are different from numbers ending in 0, 1, 2, 3, 4, 5, 6.
Oh well. I hope the game gets playtested well before it's implemented.
