To win at Tic-tac-toe, you must be able to line up 3 X’s or 3 O’s vertically, horizontally or diagonally. To make it easier for you, here are some tips on how to win
Put your first X in a corner
Putting your first X in a corner is a common strategy that wins the game most of the time. This trick often causes your opponent to make mistakes.
If your opponent does not place an O in the middle, you have a better chance of winning.
Chance to win if the opponent places an O in the middle
You have a better chance of winning if your opponent places his first O in the middle. You just have to wait for your opponent to make a mistake to win. Otherwise, the game will end in a draw.
Play your second X
If your opponent does not place his first O in the middle, you will have a chance to win. To do this, you must place your second X in one of the corners, leaving a space between it and your first X.
Place your third X properly
Placing your third X correctly will give you two ways to win. Your opponent will defend himself by blocking with his O when he sees that you have two X in the same row. However, there will always be an empty square that lines up with your first X or your second X. This strategy ensures that you always have an empty square to win, even if your opponent blocks.
Place your fourth X and win
Two empty squares will always be available to you after you place the third X. One of these squares allows you to win just by placing an X in one as well as the other.
Your opponent can only place one O to block you when it’s his turn. Place your fourth X in the square he couldn’t block to win.
