What is Tic-Tac-Toe?

Tic-Tac-Toe is the timeless two-player strategy game where you place X's and O's on a 3×3 grid, trying to get three in a row before your opponent. Play against a friend or challenge the AI with adjustable difficulty.

How to use

  1. Choose your symbol (X or O) and select whether to play against a friend or the AI.
  2. Tap any empty cell on the 3×3 grid to place your mark — players alternate turns.
  3. Get three of your marks in a horizontal, vertical, or diagonal line to win the round.

Result

You pick X and challenge the AI on Hard mode. You open in the center, the AI responds in a corner — after several moves, you manage a diagonal three-in-a-row to win.
