A Neon Labs game · Out now on iOS & Android
Neon XO
Tic-tac-toe, reimagined in neon.
Neon XO is the classic three-in-a-row you already know, rebuilt as a glowing neon arena. Every mark is drawn with animated light, every win lands with a satisfying pulse.
Play pass-and-play against a friend, or test yourself against an AI that actually thinks. No timers pushing you, no pop-ups interrupting you — just the game.
Like everything from Neon Labs: no ads, no tracking, no subscriptions. The whole game is free. If you want to, you can buy a neon background or an extra track, or tip the author — all optional, all cosmetic, none of it touches how the game plays.

A look inside Neon XO
Inside the game
Small game. Big glow.
Local multiplayer
Pass-and-play on a single device — the fastest way to settle a score.
Sharp AI opponent
A built-in opponent that plays to win when you have no one to challenge.
No ads, ever
No banners, no interstitials, no data harvesting. The whole app is the game.
Cosmetics, not pay-to-win
Optional neon backgrounds and extra tracks. Nothing you can buy changes how a match plays out.
Pure neon feel
Hand-animated marks, reactive glow and a soundtrack you can switch off.
From the studio
Built by Neon Labs.
Neon XO is the first title from Neon Labs, a tiny independent studio making simple, ad-free games. Same promise on everything we ship.
