Tic Tac Toe

Three in a row — beat the computer if you can

Tic Tac Toe needs no introduction — three in a row wins. What makes our version special is the AI: choose from Easy, Medium, or the near-unbeatable Hard level powered by game-tree logic. Beat the machine to prove your tactical skill.

How to Play Tic Tac Toe

  1. Choose your symbol — X or O — and a difficulty level.
  2. Tap an empty square to place your mark.
  3. Line up three marks in a row, column, or diagonal to win.
  4. Block your opponent's lines and plan two moves ahead.
  5. The game ends in a win, loss, or draw.

Tips & Strategies

If you start, take the center — it gives the most winning lines. If your opponent has the center, take a corner. Always check for your own winning move and your opponent's threats first; beginners who master blocking never lose on the Easy board.

Frequently Asked Questions

Can I beat the Hard AI?

The Hard level plays optimally, so a perfect game always ends in a draw — but it makes one mistake if you pressure it correctly.

Is there a two-player mode?

Yes — you can also play locally against a friend on the same device.

What are the difficulty levels?

Easy makes random moves, Medium mixes logic with mistakes, and Hard plays nearly perfect moves.
