You already
know this game.

Five pixels and an apple. Eat, grow, don't crash. You played it under a desk, on a phone with no colour and a battery that lasted a week.

You've never
played this one.

Same three seconds to learn. One rule changed — and everything after it is new.

A board dense with the player's own stone
THE ONE NEW RULE

Every snake
drags its tail.
Yours doesn't.

When you shed, your body stops exactly where it stands and hardens. It's still there in ten seconds. Still there in three minutes. Every grey block on that screen is somewhere you chose to go.

Boost tearing through stone
WHEN IT CLOSES IN

Carve doors
through your
own walls.

Catch the rhino and drive into your own stone: it cuts to glass, a floor you can cross forever but can never build on again. Every fortress ends up veined with the doors you had to cut to survive it.

THE WHOLE GAME

Stay long for points.
Or shed now and live.

Length is what you eat to earn. Length is what you shed to build wall. Length is what buries you. One resource, one decision, never enough room.

QUESTIONS
Is Ossify free?
Yes — Ossify is free to play in your browser, with no ads, no accounts, and nothing to install.
What makes it different from classic Snake?
Your tail doesn't follow you. When you shed length, your body sets where it stands and hardens into permanent wall. The board keeps that wall across runs, so you are building one fortress until it closes over you, and a finished fortress travels as a link for other players to dig. No other snake game keeps your history on the board.
What happens when I die?
The board keeps every wall you laid. You respawn on the same board and keep building, run after run, until your own stone closes over you. That ending is called FORTRESS COMPLETE, and it is the trophy.
Do I need an account or a download?
No. Ossify plays instantly in any browser at playossify.com — no sign-up and nothing to install.
Can I play on my phone?
Yes. Ossify is built for one thumb in portrait and works in any mobile browser.
Is there a mobile app?
Yes — Ossify is free on the App Store for iPhone and iPad, and it also plays free in any mobile browser. Android (Google Play) is coming soon.
Can I play with friends?
Yes. A finished fortress travels as a link. Send yours to anyone and they dig inside the world you built, where your stone is their wall. Paste a friend's link on the start screen to dig theirs.
Is this just Snake with a twist?
It's a snake game with one rule changed, and the change is total. Your tail doesn't follow you: it sets where it stood and becomes permanent wall. The fortress, the digging, the ending. Everything new falls out of that one rule.

Everywhere you've been
is in your way.
