Tic-Tac-Toe, also known as 'X-O,' is a game of strategy that challenges the intellect. It requires a logical approach that has been proven effective in securing the best possible outcome in each round. If both players use the same winning strategy, the game will always end in a draw, with no victor. However, if your opponent is unaware of this strategy, you will win whenever they make an incorrect move. In the event that the strategy is discovered by others, you could propose a more difficult variation of the game. If you're unfamiliar with how to play Tic-Tac-Toe, it's essential to learn the basic rules first.
StepsWin or Draw When Playing First
Place your X in the corner square first.Any option is valid
Try to secure a win if your opponent places the O piece in the central square first.

Win if your opponent does not place their O in the center square first.Outside

Place your third X to create a double threat. At this point, your opponent must place their O between the two Xs in the same row to block you. (If they don't, they'll lose as you'll complete a row of three Xs). Then, a vacant square will appear in the same row as both the first and second Xs, with two open rows remaining. Place your mark in this square.
- Example: Draw a tic-tac-toe grid on a piece of paper with "X O _" on the top row, "O _ _" in the middle, and "X _ _" in the bottom row. If you place your X in the bottom-right square, your third X will align with the two other Xs in the same row.

Win on your fourth move. After placing your third X, simply mark one of the two empty spaces in the double threat to secure the win. Since your opponent can only block one row, place your fourth X in the remaining unblocked square to finish the game!
Never accept defeat, even if you have to play second

Force a draw if your opponent plays in the corner. If your opponent goes first and places their O in a corner, place your X in the center. For your second move, place your X next to the edge,
not in a corner,
unless you need to prevent your opponent from forming a row of three in a line. With this strategy, every game will end in a draw. Theoretically, you could win if your opponent makes a significant mistake, like failing to notice you're aligning two pieces in the same row.
- In this section, your opponent still plays O, but remember they go first.

Force a draw if your opponent plays in the center. If your opponent goes first and places their O in the center, place your X in a corner. Then, continue blocking to ensure a draw. In fact, there’s no way to win in this setup unless your opponent stops trying or intentionally lets you win!
Aim for victory if your opponent places their O near the edge of the board.
Variants of Tic-Tac-Toe

Try a different style if every game ends in a draw. Maintaining a winning streak in Tic-Tac-Toe is fun, but your friends can still figure out how to block you from winning, even if they haven’t read this article. If that happens, every game you play will end in a draw — which gets boring. However, you can keep the same rules but change up the gameplay to make it more challenging. Try the following variations.
Engage in an imaginative game of tic-tac-toe.
Try playing tic-tac-toe in a 3D space.
Play the five-in-a-row game.
Advice
- If you are playing against a beginner, this game is a good choice. Start first and place your X near the edge. Your chances of winning only appear if your opponent places their O in the opposite corner of your X or close to one of the adjacent edges. Have you figured out how to win in these two situations yet?
- If you're seeking a greater challenge, try winning when you start first and place your X in the center of the board. If your opponent places their O near the edge (a rare move), you can secure a win. Can you visualize how to defeat them in this case?
- There are other brain games where a skilled player can win consistently, even if both players make perfect moves. For example, in the game of 'dropping chess,' the first player always wins if they follow the correct strategy.
- Think carefully before making each move.
Warning
- Even if someone has no knowledge of strategies, they can still predict your moves if you always place your first piece in the same spot every time. For instance, if you always place your first piece in the corner, try varying the corners to make it harder for your opponent to predict your next move.
