Tic tac toe (noughts and crosses, X's and O's, "jogo do galo" in Portuguese, "tres en raya" in Spanish, "morpion" in French, "ristinolla" in Finnish) is one of the oldest pencil-and-paper games still played daily. The rules are simple. The depth, once you start looking, is real.
Two players — X and O — take turns placing their symbol on a 3×3 grid. The first to line up three of their own symbols in a row, column, or diagonal wins the round. Fill all nine cells with no winner and the round is a draw. X always plays first. With optimal play on both sides, the game ends in a draw every time — which is precisely why all the depth lives in the imperfect play.
You cannot win every game of tic tac toe against an equal opponent. But you can stop losing. These six heuristics cover almost every position you will see in a casual match.
Most browser tic tac toe games haven't been touched in a decade. This one is new. Polished. Made with care.
It loads instantly — no warm-up, no loading screen, no pop-up asking for your email before you've even started. The board snaps cleanly to whatever screen you're on, whether that's a brand-new phone or a beat-up old laptop. The sound feels right.
You can pick it up between meetings, finish a round on the train, or settle a best-of-five on the couch. A friend across the country is one invite link away. A child learning the rules is one click away. It's the kind of small thing that just works, every time. If you've been looking for a tic tac toe game online that respects your time, you've found it.

No, and that's the point. Unbeatable thinks every game through to the end and always plays the perfect move. Tic tac toe is mathematically solved — with perfect play on both sides, the match always ends in a draw. Against Unbeatable, the best you can do is force that draw.
Easy plays random moves with no strategy — perfect for kids or a warm-up. Medium plays sensibly and blocks your obvious threats, but slips occasionally, so a sharp opponent can beat it. Unbeatable plays the perfect move every turn — it never loses, only draws.
The centre square. It touches four of the eight possible winning lines — more than any other cell. From the centre opening you cannot lose with optimal play. Give it up and your opponent reaches the strongest position on the board.
Rarely longer than two minutes. The longest possible game is nine moves, and most experienced players finish in five to seven. The Unbeatable bot moves almost instantly — a small intentional delay keeps it from feeling jarring.
A move that creates two winning threats at the same time. Your opponent can only block one — you win on the next move. Forks are how skilled players (and the Unbeatable bot) close out games. The fastest way to learn them: play Unbeatable a few rounds and watch its second move.
Yes. The layout adapts to any screen, the controls are sized for thumbs, and the action buttons never hide behind your phone's home bar. Rotate the device, switch between apps — the game keeps up.
On your own device. Scores, streaks, and preferences stay in your browser — they survive a page reload, and clearing your browser data clears them too. Online matches travel directly between you and your friend, with nothing kept in between.
After the page loads once, vs Bot and Local both work without an internet connection. Only Online needs the network to set up the match. A fully offline-ready version is on the roadmap.
