Can Tic Tac Toe always end in a draw?

Yes — with optimal play from both sides, Tic Tac Toe always ends in a draw. This is why the "Unbeatable" AI (which uses the minimax algorithm) can never be beaten — only tied. Try Medium mode for a more beatable opponent.

Best opening move

The center square is the strongest opening move — it gives you the most winning paths. If the center is taken, corners are stronger than edge squares.
