Sorry for delay
That is the exact answer, and thus the board looks like this:
Gameboard 4 ends in a cat's game as well.
My suggestion is that we make each category a seasaw category, so you will keep giving answers until no one can.
I would also suggest sudden death, where we simply go with that until one person wins a board, and then they win the game.
My other suggestion would be to scrap Tic Tac Dough and play an entirely new game.
Since I'm changing the rules midswing, please let me know if either of those plans work for you, and if not, we'll discuss another alternative.
