How to improve at Tic-Tac-Toe
Tic-Tac-Toe is a compact strategy game where every square matters. You play first as X, but winning consistently requires more than choosing the center. Create two possible winning lines at once while preventing the computer from doing the same. A draw is a good defensive result when no safe winning move remains.
