The Ancient Origins and Modern Revival of Tic-tac-toe

Games resembling Tic-tac-toe have roots dating back thousands of years. Archaeological evidence shows that ancient Egyptians played a similar three-in-a-row game around 1300 BC, and the Roman Empire had its own version, with Emperor Claudius being an avid player. Over time, Tic-tac-toe evolved from a folk game played with sticks in sand or chalk on slate to the familiar 3×3 grid format we know today, emerging in the late 1800s.

It gained popularity in Victorian England as a pub and tavern amusement but faded into the background in the 20th century with the advent of video games. However, it made an unexpected comeback in the 1950s when mathematicians started studying it as a theoretical model of strategy. This even led to an international Tic-tac-toe tournament in London in 1953.

The digital age has further revitalized interest in Tic-tac-toe, making it one of the easiest games to code into everything from children’s toys to smartphone apps. It’s safe to say that Tic-tac-toe will continue to captivate new generations.

Basic Rules and Gameplay of Tic-tac-toe

For those unfamiliar with the game, the rules are straightforward:

  • It is played on a 3×3 grid with nine empty squares.
  • Players take turns marking the squares with Xs and Os.
  • The first player to complete a horizontal, vertical, or diagonal row with their mark (X or O) wins.
  • If all nine squares fill up without a winner, the game results in a tie.
  • Typically, the X player goes first, and then players alternate between Xs and Os.

With such a small grid, games are usually quick, often ending in a win, loss, or draw within ten moves or fewer. This makes every move critical. Understanding Tic-tac-toe strategy is essential to succeed against skilled opponents.

Essential Tic-tac-toe Strategy Tips

Tic-tac-toe is easy to learn but requires practice to master. Here are some key tips to follow:

  • If you go first, place your initial X in a corner square, as this provides the most options.
  • Respond to your opponent’s first move by marking a square that blocks their play and furthers your own row.
  • Plan a few moves ahead to set up rows where you have two marks with the third square open for your next turn.
  • When your opponent has two marks in a row with an open third square, block that row to prevent their win.
  • If you have two marks in a row, don’t play your third move right away; leave it open to bait your opponent into blocking and setting up your win.
  • Whenever possible, occupy the center square for maximum control of the board.

Mastering these strategic concepts will significantly improve your Tic-tac-toe skills. Against evenly matched players, games often result in draws. To consistently win, you need an unbeatable strategy.

How to Beat Tic-tac-toe Using an Unbeatable Strategy

In Tic-tac-toe, the X player typically has the advantage when they play first. By following a set sequence of optimal moves, X can guarantee a win or a draw every time. Here’s an unbeatable strategy:

  1. First Move: If you’re X, start by placing your X in a corner square, providing the most opening options and center control.
  2. Second Move: Respond to O’s first move by marking a square that both blocks’ O’s play and sets up your own row. The best responses to common O’s opening moves are:
    • If O marks the center, place your X in an unoccupied corner, threatening O’s center play and starting your own corner row.
    • If O marks a corner, place your X in the center to block their corner start and establish your central position.
    • If O marks an edge square, place your X in the adjacent corner to block O’s edge move and start your row.
  3. Third Move: With your first two optimal moves as X, you will have created a 2-in-a-row situation, with the option to win on your next turn. No matter what O plays, complete your row and win or block any immediate win threat from O.

By following this sequence, X can guarantee a win or draw every time. If both players employ this perfect strategy, the game will always end in a tie. However, against less-than-optimal opponents, X can win 100% of the time using this approach.

Mastering Difficult Computer Opponents by Recognizing Win Patterns

To consistently beat a Tic-tac-toe computer or mobile app on expert or impossible difficulty settings, you must play flawlessly. AI opponents utilize perfect Tic-tac-toe strategies and are not easily outsmarted. To win, you must recognize patterns indicating when the AI is one move away from victory and block accordingly. The main patterns to watch for are:

  • Straight Row 2-in-a-Row: If the AI has marked the edges or diagonal ends of a full row, block the center immediately to prevent them from completing the row.
  • Corner + Center 2-in-a-Row: If the AI marks both a corner and the center square, block the remaining corner to prevent them from completing a diagonal row.
  • Forked Rows 2-in-a-Row: If the AI threatens two rows simultaneously, block the row with fewer remaining spaces for the AI to win, and don’t let both forked rows materialize.

Beat Impossible Difficulty by Turning Defence into Offense

The best Tic-tac-toe players are adept at switching between defensive and offensive moves. After blocking the AI’s immediate victory setups, take the initiative and go on the offensive. Look for opportunities to complete a row or create a 2-in-a-row threat, forcing the AI to block you and allowing you to regain board control.

Some additional strategies and moves to help you win Tic-tac-toe

1. The “Double Threat” Move:

  • When you have two marks in a row, consider placing your next mark in a position that simultaneously threatens two potential wins. For example, if you already have two Xs in one row and an empty square in another row, place your X in the square that connects both rows. This forces your opponent to choose which row to block, allowing you to win on the next move.

2. The “Center Control” Move:

  • If you have the opportunity, aim to occupy the center square early in the game. The center square provides access to the most lines and can give you a strategic advantage by controlling the board’s core.

3. The “Edge Strategy” Move:

  • When playing as X, placing your first X in a corner is usually the best move, but if you want to try a different approach, consider placing your X on an edge square. This move can lead to unique tactics and catch your opponent off guard.

4. The “Block and Win” Move:

  • Pay close attention to your opponent’s moves and look for opportunities to block their potential wins while setting up your own. If your opponent is close to forming a winning row, make sure to block that row on your turn.

5. The “Corner Control” Move:

  • As the game progresses, try to secure two opposite corner squares. This creates multiple potential winning lines, making it difficult for your opponent to block all of them.

6. The “Empty Corner” Move:

  • If you notice that there is only one corner square left unoccupied late in the game, prioritize claiming it. The last corner often becomes the deciding factor in who wins the game.

7. The “Threatening Diagonals” Move:

  • Keep an eye on diagonal rows. If you have marks on two diagonal squares and the third is open, you’re in a powerful position. Your opponent will need to block one of the diagonals, and you can use the other to win the game.

8. The “Fork Threat” Move:

  • If you have two marks in a row that can lead to a fork, which is the opportunity to win in two different ways on the next move, use this to your advantage. Your opponent can only block one of the potential wins, leaving the other open for your victory.

9. The “Center Block” Move:

  • If your opponent occupies the center square early in the game, make sure to place your mark in a corner. This will prevent them from forming an easy row through the center.

With this endgame knowledge, you’ll know how to achieve the most favourable outcomes from any Tic-tac-toe position.


Becoming a Tic-tac-toe grandmaster takes practice, but anyone can master the game by understanding the basic rules, essential strategies, recognizable win patterns, and endgame scenarios. By following these tips, you can unleash your inner Tic-tac-toe pro and consistently outsmart your opponents, whether human or computer.
