Dig into the pile by hand. Every key you take makes the mountain sink a little.
One vault. One million keys. Only one opens the door.
Dig by hand, by shovel and by magnet, test key after key, melt the wrong ones into brass and buy upgrades until the mountain is gone.

THE GAME
Locked in a vault. With a million keys.
You are locked in an underground bank vault from the 1960s with a single way out: a three-metre steel door with one lock. In the middle of the room sits a mountain of one million brass keys. Exactly one of them opens the door.
One Million Keys is a relaxing, slightly absurd first-person simulator about doing one thing really well: pick up keys, test keys, throw keys away. The mountain is real: every one of the 1,000,000 keys exists, sinks as you dig and disappears when you take it. Before long you have a shovel in hand, two funnels pulling keys onto a conveyor belt, an automatic tester slamming batches into the lock and a furnace turning every wrong key into brass. Brass buys upgrades. Upgrades empty the mountain faster. The mountain shrinks. The right key gets closer.
The clock only stops at the very end. What's behind the door is for you to find out.
TRAILER
One million keys in 25 seconds
25-second trailer: the vault door, the mountain of one million keys seen from the entrance, a hand digging, the shovel flinging keys, the door testing keys, funnels and a conveyor belt carrying keys to the tester, the X-ray revealing the right key and the door starting to open with warm light. It ends with the logo and “Coming soon on Steam”.
Sound on: every key has its own clink.

Pick. Test. Melt. Buy.
Start with empty hands and room for ten keys. Pick one, walk to the door, turn it. Clank.

2 · Test
Turn them in the lock one by one. Clank. Wrong.
-
3 · Melt
Every wrong key goes into the furnace and comes out as brass.

4 · Buy
Brass buys the shovel. The shovel brings twenty keys at a time.
Every wrong key pays brass; brass pays for upgrades; upgrades bring wrong keys faster. The loop closes itself.
WHAT MAKES IT DIFFERENT
One million real keys
Each one is counted, lowers the pile when you dig and falls with physics when you throw it. No painted-on pile.
- 1,000,000 keys, every one counted
- 189 upgrades
- 7 branches
A vault that looks like a vault: warm light from industrial lamps, dust in the air, brass that reflects, a steel door that groans. A real sound for every clink.

FAQ
Frequently asked questions
What is One Million Keys?
A relaxing, slightly absurd first-person simulator. You are locked in a vault with one million brass keys and only one opens the door. Dig, test, melt the wrong ones into brass and buy upgrades until you find the right one.
When does it come out and how much will it cost?
Coming soon to Steam. Date and price have not been announced yet. Add it to your wishlist and Steam will let you know at launch.
How long is it?
A run takes about two hours. Then you can refill the vault and go again, faster, with everything you bought.
Do I really have to test a million keys?
Not necessarily: the right key can be anywhere in the mountain. And you won't be stuck with bare hands for long: shovel, magnet, funnels, conveyor belt, automatic tester and the Scent, which points at the right key.
Any microtransactions? Do I need to be online?
No and no. No microtransactions, no online requirement.
Can I play with a controller?
Yes: keyboard and mouse or controller (Xbox and DualSense).
Which languages?
English, Brazilian Portuguese, Spanish, German, French, Russian, Simplified Chinese and Japanese.
Which platforms?
Windows and macOS (Apple Silicon, macOS 13+).
Is it multiplayer?
It's a single-player game. But everyone adds to the same worldwide counter of tested keys, and you can send your seed code to a friend so they play the same vault.
Is there a challenge for those who want more?
There's Purist mode: no upgrades, hands only. And you can refill the vault and race your own time.
Does the game use AI?
