How to Play Tic-Tac-Toe Online
Tic-Tac-Toe is the classic 3x3 grid game for two players. One player is X, the other O, and they take turns marking empty squares. The first to line up three marks in a row — horizontally, vertically, or diagonally — wins.
Objective
Get three of your marks in a row before your opponent does.
Setup
- Draw or display a 3x3 grid (9 squares total).
- One player is assigned X, the other O.
- X traditionally moves first.
How to Play, Step by Step
Take turns marking squares
Each player places their mark in any empty square on their turn.
Look for two-in-a-rows
Watch both your own and your opponent's lines — block any open three before it's completed.
Claim the win
The first player to complete a row, column, or diagonal of three matching marks wins immediately.
Call a draw
If all 9 squares fill with no three-in-a-row, the game ends in a draw — the most common outcome with two skilled players.
Rules to Know
- A line counts as any full row, column, or diagonal of three matching marks.
- Once a square is marked, it can't be changed or reused.
- The game ends immediately when a line is completed — remaining squares don't matter.
- With perfect play from both sides, every game ends in a draw.
