Classic 3×3 Xs and Os, online and in real time — challenge a friend with one shared link, free and no signup.
Play Tic-Tac-Toe online multiplayer — also known as noughts and crosses — against a specific friend instead of a random stranger. Create a room on Play Lounge, share the link, and the two of you trade Xs and Os on the same board in real time. No accounts, no app store, no setup — just open a tab and play.
On your own? Take on the Tic-Tac-Toe AI at three levels. The hard setting plays perfectly, so every game it does not lose is a draw — a fun way to test whether you really know the optimal openings. It is free, works offline as an installed app, and runs on any device.
Create a private room and send the link. No account on either side.
Real-time over WebSocket, comfortable even on a slow connection.
A built-in AI opponent with three difficulty levels when nobody is around.
Browser, installable PWA, and native iOS and Android apps.
Two players alternate placing their mark — X or O — on a 3×3 grid. The first to line up three of their marks in a row, column, or diagonal wins. If all nine squares fill without a line, the game is a draw, which happens often once both players know the strong opening moves. Take a corner or the center first, and always block your opponent's two-in-a-row before chasing your own.
