- How many were draws?
- Did the player going second ever win? If so, what mistake did the first player make?
- Here is the claim: if both players play well, it is always a draw. Do your games agree?
- If that is true, is noughts and crosses still worth playing? Say who it is worth playing with, and why.
- A game where both sides playing well always ends the same way is called solved. Name another game you think is solved, and one you are sure is not.
