OSSIFY
A daily puzzle about consequence

Your tail doesn't follow you. It turns to stone.

Ossify is snake where every move you have ever made is still on the board. Your history fossilizes into walls. One board a day, the same board for everyone.

It didn't start here.

Today's puzzle is one board in a line that reaches back almost thirty years, to the first snake that ever crawled across a phone.

Keep scrolling. We'll rewind.

1997

Snake taught the world to grow.

A brick phone. Four directions. One rule: eat, grow, don't touch yourself. The tail followed you everywhere you went, then politely got out of the way.

Forgiving, in hindsight.

2007

Screens changed. The rule didn't.

Color arrived, corners softened, the snake got faster. But the loop stayed merciful: your past moved with you, and then it vanished.

Nothing you did was permanent. That was the flaw.

2026 · OSSIFY

We changed the one rule that mattered.

Now the tail doesn't follow. It fossilizes where you leave it and becomes wall. Rats, birds, eggs and frogs live on the board. Your own history is the maze, and every decision is the same decision: spend length, or keep it?

New board every midnight · everyone plays the same one

01

Grow

Everything you eat becomes length. Length is your score multiplier and your only currency.

02

Shed

Bank your tail as stone. It stays on the board forever, exactly where you left it.

03

Survive

The walls closing in are your own decisions. Die entombed in your history, or don't.

How buried are you

Growth creates pressure. Pressure creates choice.

What lives out there

The board is not empty. Four things want something from you.

DRAWN WITH THE GAME'S OWN VECTORS · NOT ILLUSTRATIONS
RAT +2 The everyday meal. Six of them share the board at any moment, shuffling a cell at a time while you close in.
FROG CLEARS WALLS It lands on the thickest patch of your own stone, deliberately. Eat it and a crater of that wall is gone. It hops faster than the bird.
BIRD +5 · LUNGE It moves while you chase it, and leaves after fifteen seconds. Catching one buys a lunge · a four-cell snap forward that grabs prey out of reach · and a multiplier bonus that survives your next shed.
RHINO DRILLS WALLS It only turns up once there are walls worth breaking. Grab it and you charge straight through your own stone · your way out of a corridor of your own making.
the frog, the bird and the rhino all time out · only the rats wait for you
What's in it

One board a day. Four speeds. Nothing to buy.

Daily

One board. Everyone.

A new board at midnight, identical for every player in the world. Free play deals a fresh random one whenever you want.

Tiers

Four speeds, up to ×4.5.

STEADY, RATTLE, QUICK, BLUR. Faster tiers score more. The accessibility speed setting is separate and never costs you any.

Scoring

Length is the multiplier.

Everything you eat becomes length. Eat fast to chain, up to twelve links, and skimming a wall without touching it pays too.

Controls

One thumb, portrait.

Swipe anywhere to steer, arrow keys on a desktop. An optional on-screen pad sits on whichever side you hold.

Promise

Free. No ads. No account.

Nothing to buy, nothing to unlock, no timers and no gacha. The whole game is there the first time you open it.

Privacy

Your scores stay on the device.

The only thing sent is an anonymous summary of a finished run. No name, no email, no device ID, no third-party trackers.

Common questions.

Is Ossify free?
Yes. Ossify is free in your browser and free on the App Store, with no ads, no accounts and nothing to buy.
What makes it different from classic Snake?
Your tail doesn't follow you. When you shed length your body freezes where it stands and hardens into permanent wall, so you spend the run dodging everywhere you have already been.
What is the daily board?
Every player in the world gets the same board each day, so a score is a comparison rather than luck. A new board arrives at midnight.
Do I need an account or a download?
No. Ossify plays instantly in any browser at playossify.com, with no sign-up and nothing to install.
Can I play on my phone?
Yes. Ossify is built for one thumb in portrait, works in any mobile browser, and is a free universal app on iPhone and iPad.
How hard is it?
There are four speed tiers: STEADY, RATTLE, QUICK and BLUR, scoring at 1.0x, 2.0x, 3.2x and 4.5x. Faster tiers pay more. The accessibility speed setting is separate and never costs you score.
What's next for Ossify?
A versus mode is in development: you and a rival snake on one board, where the fossil walls you shed become traps for each other. Android is coming soon. The daily solo puzzle stays the heart of the game.
