AbigailII: Abigaill, I appreciate your comments, as always, since they provide smart
insights into the game rules and so on ... however, I think I found out an elegant solution to Knights of Fury ... please read my last modification to the rules I posted on the blog ... mirrors are not used anymore, only 4 groups of numbers, those with digits 7,8,9 plus 6 doubles that give a margin of 37 percent of all the numbers on the board ... so, as an effect, we have well ballanced game having "solo" numbers and those that cause other numbers to disappear ... you are right, it will not be a shorter game but the illusion of having a smaller board will make it "shorter" ...
you were also right saying that 25 percent of numbers have no mirrors ... but, instead of lamenting I turned around the whole idea and gave up the need for mirrors and replaced them with non-mirrors as the numbers that cause disappearing ... as you can see, there are many ways to let the fantasy manouver around the issue ...
thanks again,
Andy.

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.

AbigailII: you are right, eliminating mirrors wil make this game even one more move longer, if played till the end ... it's still fast game ... compare to Ludo, Halmas, Reversi, Chess, racing backagammon, not even mentioning Go ...
I understand that you may find some rules inelegant, but I do not understand why ? Because numners differ from each other ? this is what you say ...... look, during the game, you will be trying to find the best "deals" ... one of the option will be to look for doubles or "7,8,9"
to limit opponent's choices ... and it's up to the author to define those "chosen" powerful numbers or features ... in Knight Fight it was kind of easy due to the size of the board ... here it's more challenging but I think it will be playable quite well ...
and you will excel in this game ... you showed me twice in Knigh Fight, that this concept is not a stranger to you.
Best regards, and keep commenting. I appreciate it deeply.
Andy.
