Place your second X in the opposite corner from your first, so there’s a line going “X O X” diagonally across the board.

For example, say your first X is in the top left square, and your opponent puts an O in the top middle square. You can put your second X in the bottom left corner, or the bottom right corner. Don’t put it in the top right, since that would put an O between your two X’s instead of an empty space. {“smallUrl”:“https://www. wikihow. com/images/thumb/d/d6/Win-at-Tic-Tac-Toe-Step-3Bullet1. jpg/v4-460px-Win-at-Tic-Tac-Toe-Step-3Bullet1. jpg”,“bigUrl”:"/images/thumb/d/d6/Win-at-Tic-Tac-Toe-Step-3Bullet1. jpg/aid29798-v4-728px-Win-at-Tic-Tac-Toe-Step-3Bullet1. jpg",“smallWidth”:460,“smallHeight”:345,“bigWidth”:728,“bigHeight”:546,“licensing”:"<div class="mw-parser-output">

For example, take a piece of paper and draw a tic tac toe board with the top row “X O _”, the middle row “O _ _,” and the bottom row “X _ _. " If you place your third X in the bottom right corner, it’s in line with both of your other X’s.

In this section, your opponent is still playing O’s, but remember they get to play first this time.
