|They actually sell these now. Profitable? No idea.|
As for the name, it's due to American silliness. The British called it noughts and crosses, after the Xs and Os. (I believe we should not call them X's and O's; apostrophes would imply possession). Anyway, a game of "tic-tac-toe" existed, but was entirely different, and we seem to have just mixed them up, intentionally or not.
|So that game would never happen. But Roman-style?|
So I wonder how they played. Presumably, they took turns putting down their pieces...but since they only had three each, they had to pick up and move the pieces for their fourth (or later) moves. Could this game be winnable? Perhaps. I'd love to give it a try. Anyone up for ancient Roman "zeri e x?"
