About Tic Tac Toe 2 Player
Tic Tac Toe 2 Player is a free browser game built for 2026 devices and 2026 attention spans. Pick a mode, play a round in seconds, move on with your day.
The two 2-player modes — local and online — are the heart of the product. The online mode uses peer-to-peer WebRTC, so your moves travel directly between your browser and your friend's with no central game server in between. Playing solo? An unbeatable Minimax AI is one click away.
Who builds this
The project is maintained by Antigravity Dev. The source is deliberately small: vanilla JavaScript, a single CSS file, a Minimax engine for the bot, and PeerJS for WebRTC signalling. We treat performance, accessibility, and clarity as features — not nice-to-haves.
What we're optimising for
Speed. The page loads instantly because there's no framework runtime to download. Sound effects are synthesised live in the browser through the Web Audio API instead of streamed as audio files. The whole site weighs a handful of kilobytes.
Craft. Real iOS safe-area handling, real touch targets, and a board that snaps cleanly between portrait and landscape. The kind of details that take a thousand commits to get right.
Honesty. No artificial scarcity, no fake leaderboards, no pop-ups begging for an email. You came here to play tic tac toe — we get out of the way.
Roadmap
A fully offline-capable PWA, a 4×4 variant, and a tournament mode for the Online side are on the list. We ship in small, frequent releases — open the contact page if there's something you want us to build next.
