More about this game
Neon Tic Tac Toe is a classic board game played on a 3x3 grid against a computer opponent. The goal is to align three of your marks (X) horizontally, vertically, or diagonally before the computer (O) does. The game tracks your wins and the computer's wins across multiple rounds. A round ends when either player gets three in a row, or all nine cells are filled, resulting in a draw. You can adjust the computer difficulty to easy, balanced, or expert, and even choose who starts the round.
Tips
- Start in the center or a corner to maximize your chances of creating multiple winning lines.
- Always check if the computer has two marks in a row and block them immediately.
- If you play on expert difficulty, the computer will use a minimax algorithm, so aim for a draw if you can't win.
