Free tic-tac-toe,
no download needed.
SuperTac is a completely free tic tac toe game you play straight in your browser. Choose an emoji as your piece, pick a board from classic 3×3 up to a huge 10×10, and play the computer or your friends.
No download. No signup. Works on phone, tablet and desktop.
Classic rules, or something wilder
Play the 3×3 game you grew up with, or stretch the board out and set how many in a row you need to win — three, four or five. Diagonals count, and bigger boards make for much longer, more strategic matches.
Play alone or with friends
Face one of five AI characters with different playing styles, pass one device around with up to nine players, or share a room link so friends can join from anywhere.
