Problem Ten: The Game of Know
Sep 29th, 2006 by Percy
Explain the rule in the Game of Know, described below:
I know pizza but not hamburger. I know happiness but not sadness. I know Jill but not Jack. I know mice but not cats. I know English but not French. I don’t know red, blue, yellow or green - in fact, I don’t know colours at all.
I don’t know the rules to the game, but I do know its instructions.
Update: Solutions have been posted!
you only know things with the letter “i” ?
