About this game
Tic-Tac-Toe is a strategic grid game where you play as X against an AI opponent controlling O. Take turns placing your mark in empty squares on a 3×3 board, aiming to line up three of your marks horizontally, vertically, or diagonally before your opponent does. Each game is quick but demands forward thinking—one wrong move can cost you the match.
Choose from three AI difficulty levels to match your skill: Easy (30% optimal play with random moves), Medium (70% optimal with occasional mistakes), or Hard (100% minimax algorithm that plays perfectly and never loses). The Hard AI will draw or win every time unless you make no mistakes. Your current win streak is tracked and displayed, motivating you to improve your strategy and maintain perfect play.
When a player wins, the winning line is highlighted in signal orange. The game detects draws automatically when all squares are filled with no winner. This implementation combines classic Tic-Tac-Toe rules with a clean, modern interface and intelligent AI opponents. Play for free on desktop or mobile—no account required.
