Shun ’em … can’t stand ’em!! Never was a fan, prefer pens … but seems like common sense for a puzzle player to be friends with the pencil?! Not I, and maybe a wee bit has to do with my arrogance and contempt (yes ME … and said maybe y’all, lol) in solving puzzles … and I’m talking about my fave KENKEN … my preference: the 36 grid game (challenging version). The last one had me mentally focused and concentrating with my ball point firmly held in hand, ready to pounce … and even though it was a doozy to solve, did!! At times not so simple, but always … and inevitably only a matter of danistrulytheman time!! Ink you KK!! 😉
