One shared vault · Robinhood Chain
Crack the vault. Keep the stock inside.
Real Robinhood stock tokens sit in one vault. Anyone can try its three-number lock for free; every wrong try leaves a public clue, and the first wallet to hit the combination takes everything inside.
I The teller cage · ground floor
What's in the vault.
Robinhood stock tokens, the real ones on Robinhood Chain: NVDA, TSLA and friends. The vault is one wallet, and its balance is read from the chain every few seconds.

Seeded by the team. After launch, refilled by hand from creator fees. Not automatic, no schedule, no amount promised.
II The lift · B1 → B3
Three numbers. One stethoscope.
Set three numbers, 0–39, and try the lock. Every wrong try is public: the stethoscope reports whether one of your three numbers — the one it's listening to — was dead on, within 3, or cold, and the lock resets for five minutes. First wallet to hit all three takes everything inside.
- click dead on
- warm within 3 (39 → 0 wraps)
- cold 4 or more away
III The corridor · B3
Every try is on the wall.
The combination is committed by hash before each round and revealed when it's cracked, so anyone can re-check every lamp. Every try, right or wrong, is listed with its wallet and its clue.

Nothing hidden
Proof →The vault is a wallet run by our server, not a contract. Every refill and every payout is a public transaction on Robinhood Chain, listed on /proof with its hash. The combination is committed by hash before each round and revealed when the round is cracked.
No round is open yet, so there is no commitment to show.

The rules
Docs →Set three numbers, 0–39, and try the lock. Every wrong try is public: the stethoscope reports whether one of your three numbers — the one it's listening to — was dead on, within 3, or cold, and the lock resets for five minutes. First wallet to hit all three takes everything inside.
- Practice is free and needs no wallet: a private lock with its own combination, same rules, no reset, no prize.
- Real tries are free too: arming signs one message, sends no transaction. A wallet needs at least one transaction on Robinhood Chain.
- Before launch: 2 real tries per wallet per UTC day. Day resets 00:00 UTC.
- After every accepted real try the lock resets for five minutes, for everyone. First valid try after that wins the slot.
Stethoscope on A
Turn the wheel to a number and let go; it moves on to the next tumbler. Tap A, B or C to go back.
Practice has its own secret combination and the same rules, with no reset and no prize.
Arming signs a message with your combination. It costs nothing and sends no transaction. It fires the moment the lock opens.
