- a game without defects isnt necessarily good. tic-tac-toe has no defects,
- but is hardly a "great abstract game".
-
- i have created a variation of the 5-in-a-row family of games that is
- played on a hexagonal grid of dots. you cover each dot with one of
- your stones. because there are only 3 ways to make 5-in-a-row, instead
- of the 4 on the square board, i threw away the double-3 rule with a grin.
- after trying this game out with several friends, the missing double-3
- defect rule seemed to be truly unneeded anymore. however, the complexity
- - while still quite high enough for me - is still so far below go or chess
- that this defectless game wont make my "great abstract game" list either.
- fun though. i have another game using the same setup that could be much
- more complex....someday maybe.
