How to Use Tic Tac Toe
- Choose your opponent. Play against a friend on the same screen (Player vs Player), or challenge the computer. The computer uses minimax logic, making it unbeatable — you can at best tie.
- Click a cell to place your mark. Player 1 is X, Player 2 (or the computer) is O. Take turns selecting an empty square on the 3×3 grid.
- Watch for the win or draw. The game highlights the winning row, column or diagonal. If all squares fill without a winner, it declares a draw.
- Click New Game to replay. The board resets instantly. In two‑player mode, the starting player alternates automatically for fairness.

Frequently Asked Questions
Why is the computer opponent unbeatable?
It uses the minimax algorithm to evaluate all possible future moves. In Tic Tac Toe, perfect play always results in a win or a draw. The computer plays perfectly, so you cannot beat it; the best outcome is a tie.
Can I play against the computer and a friend at the same time?
No, you choose one mode at a time. The two modes are separate: Player vs Player for a shared‑screen human game, or Player vs Computer for solo play.
Is the game board random or does the computer always start the same way?
The computer responds to your moves. If you play first, you can choose any square. The computer then counters optimally, making each game feel slightly different depending on your opening move.
Is Tic Tac Toe free and private?
Yes — it is 100% free, needs no sign‑up, and everything runs in your browser; your data never leaves your device.
