A simple, addictive two-player game. Place your marks on a 3×3 grid and line up three in a row before your opponent does.
The goal is to line up three of your marks. Just 4 simple steps to victory.
The board is a 3×3 grid of nine empty cells. One player places X's, the other places O's.
Take turns claiming any empty cell. Once placed, a mark can't be removed or moved.
Three of your marks in a row — horizontal, vertical or diagonal — wins instantly.
If all nine cells are filled and there's no line, it's a draw. Then start a fresh quick game.
Tic-Tac-Toe is a game everyone knows from childhood: the rules take five seconds to grasp, and a game lasts a minute. With perfect play on both sides it always ends in a draw, so all the fun comes from traps and your opponent's slips. At muta.pro you can play with a friend by room code or against a bot of varying strength — right in your browser, no install needed.
