Tic Tac Toe

Play Tic Tac Toe Online
Tic Tac Toe is a classic two-player game where players take turns marking a 3×3 grid with X and O. The first player to get three marks in a row wins. You can play against a friend on the same device or challenge the AI.
If you played this as a child, you probably discovered that the game almost always ends in a draw when both players know what they are doing. That is by design, Tic Tac Toe is a solved game in game theory.
What is Tic Tac Toe?
Tic Tac Toe (also called Xs and Os or Noughts and Crosses) is a zero-sum game played on a 3×3 grid. Two players take turns marking spaces with their symbols. The player who places three marks in a horizontal, vertical, or diagonal row wins. If all nine spaces are filled with no winner, the game is a draw.
Historical Context
The game dates back to ancient Egypt and the Roman Empire. Romans played a version called Terni Lapilli, scratching marks on surfaces instead of using paper. The game has survived for centuries because it is simple to understand and quick to play.
Game Theory
Tic Tac Toe is a solved game. With perfect play from both sides, the game always ends in a draw. Human error creates the challenge, and the fun.

Strategy Tips
Take the Center
The center square is the most valuable position. It participates in four winning lines (one horizontal, one vertical, two diagonals).
If you go first, take the center. If you go second and the center is open, take it immediately.
Respond to the Center
If your opponent takes the center, take a corner. Taking an edge piece (non-corner) when the center is occupied is a mistake against a skilled opponent, it typically leads to a loss.
Look for Forks
A fork creates two simultaneous threats. Your opponent can only block one, so you win on the next turn. To set up forks, try placing marks in three corners, or the center and two opposite corners.
Psychological Play
In PvP mode, playing quickly can pressure your opponent into mistakes. Use the tool's responsiveness to keep the pace fast.
