What is FL80R?

One run. 80 floors.

FL80R ("Floor 80") is a browser-based puzzle & logic game. Climb an 80-floor tower of riddles — hidden text, typed answers, math traps, memory floors, chase floors, and a cat boss waiting on every tenth floor. There are no saves and no checkpoints: it's one continuous run to the top, wrapped in a retro terminal / CRT aesthetic. Play solo with a pen and paper, take turns with friends, or stream it and let an audience shout answers.

Why play

What makes it tick

🎲

Fresh every run

Every new session rolls a brand-new set of riddles. No two runs are the same. Only the boss floors and Floor 80 are fixed.

🚫

No safety net

No saves, no checkpoints. You finish it in a sitting or you start over from the bottom.

✏️

Bring a pen

Memory floors ask what your answer was several floors ago. Write things down — memory is not optional.

👀

Look closely

On hidden floors the answer is buried in the screen itself. The obvious is rarely correct.

📺

Streamer-friendly

Built for an audience. Challenge chat to spot the hidden text before you do.

💾

Free & instant

Runs in your browser. No downloads, no accounts, no tracking. Installable as an app.

The void. No zones, no landmarks, no end — just floors forever, scaling with depth until a cat sighting becomes legend.

Feed the cats

Every 10 floors, a cat demands tribute

FL80R is free and always will be. If it made you smile (or scream), tossing a coin keeps the cats fed and the floors coming.
