The Rules of Tic-Tac-Toe

To start, let's get to know the goal of tic-tac-toe. The winner is the player who gets three in a row one on a 3 × 3 grid earlier, or four on a 4 × 4 grid, five on a 5 x 5 grid, and so on.

At the beginning, a player needs to draw a board and creates a square grid, usually 3 × 3 or 4 × 4. In a 3 × 3 grid game, the player who plays "X" usually comes first. The two players alternate to draw Xs and Os on the board until either player has three in a row, horizontal, vertical or diagonal, or until all the squares on the grid are filled. If the player can draw three Xs or three Os in ,or Os line, then the game results in a draw.

One of the best tips for the tic-tac-toe game involves creating a "cross" that is putting your marker in such a way that you have a chance to win by two ways at the next turn. In this way, your opponent can only block one and you win that.

If you play on a 4 × 4 grid, the game rule is also the same. "X" player first. In addition, players alternate Xs and Os on the board until the line is horizontal, vertical or diagonal, or all 16 grids are filled. If all 16 squares are filled and the player doesn't have four in a row, the game is a drawing.

Of course, the game Tic-Tac-Toe can also be played on a larger grid, such as 10 × 10 or even 20 × 20. For any 6 × 6 or larger grid, it may be best to make the target obtain five consecutive goal. This transforms the basic game of tic tac toe into a more complex game similar to the board game Gobang. Similarly, Gobang's goal is to score five marks in a row for a player.
