How to play Tic-Tac-Toe

What you need

A 3x3 grid, which you can draw on any piece of paper. One player is X and the other is O.

How to play

Players take turns writing their mark in an empty square. X usually goes first.

How to win

The first player to get three marks in a row, across, down or diagonally, wins. If all nine squares fill up with no row of three, it is a draw (often called a "cat's game").

Simple strategy

Take the center if it is free. If not, grab a corner.

If you have two in a row, finish the line. If your opponent has two in a row, block them.

Look for a move that makes two lines of two at once, so your opponent can't block both.

Questions and answers

Can you always win at tic-tac-toe?

No. When both players make no mistakes, every game ends in a draw. You win only when your opponent slips up.

What is the best first move?

The center or a corner. Both give you the most ways to make three in a row.
