Tic Tac Toe

Tic Tac Toe is the timeless two-player grid game where the goal is simple: be the first to line up three of your marks — X or O — in a row, column, or diagonal on a 3x3 board. This version runs entirely in your browser with zero setup. Pick two-player mode and pass the keyboard with a friend, or switch to Computer mode and take on an AI opponent that actively blocks your winning moves and aims for its own.

Every session tracks wins, losses, and draws across rounds so you can keep a running score without starting over. When a game ends, the winning line lights up in green to make the result instantly clear. Hit New Round to play again with the same scoreboard, or Reset Scoreboard to wipe everything and begin fresh. No account, no download, no waiting — just open and play.
