It has been a couple of days since I've launched a new Hive app (sorry about that). Announcing Hiveheist.com. I know, I know. It’s been at least 48 hours since the last app launch. I’m clearly slipping.
Today I’m launching HiveHeist.com: a provably-fair Hive game where everyone tries to crack a 4-digit vault combination before the vault resolves.
What is HiveHeist?
HiveHeist is simple:
- A vault is open for a fixed window (currently ~7 days).
- Players submit 4-digit guesses by sending the attempt fee with a valid memo format. Each attempt costs 0.500 HIVE
- When the target block arrives, the vault resolves.
- The combination is revealed, attempts are scored, payouts are calculated, and the next vault starts immediately.
No one (including me) knows the final code ahead of time, because it’s derived from a future Hive block hash.
How the payouts work
There are match tiers:
- 4/4 (Exact): biggest payout slice
- 3/4 (Strong): smaller fixed tier slice
- 2/4 (Partial): refund-style payout
- 1/4 (Weak): smaller refund-style payout
- 0/4: no payout
Payouts are capped by available pot, and the engine is designed so total payouts never exceed the vault balance.
The carry-forward mechanism (the fun part)
If nobody hits 4/4, the vault is uncracked.
That does not zero out the pot.
After tier payouts are applied, whatever remains is rolled into the next vault as seed. So jackpots can snowball across rounds until someone finally nails the exact combo.
Yes, that means a vault can keep climbing across multiple rounds if exact hits don’t happen.
What I tightened before this announcement
I didn’t want to ship this without hammering on mechanics and liquidity safety, so I added/fixed a bunch of core behavior and tests:
- Added real Mongo integration tests (not mocks) for:
- transfer ingestion + attempt recording
- vault resolution lifecycle
- same-block resolution/rollover behavior
- Added rollover-focused tests for large uncracked pots (including 1000 HIVE scenarios).
- Hardened payout math so partial/weak refunds are fairly distributed when funds are constrained.
- Enforced late-attempt boundaries around resolution blocks.
- Tightened deterministic resolution/combination handling and config-driven economics.
Come try it
If you like on-chain games, transparent mechanics, and watching jackpots roll forward, give it a run:

As always, play responsibly. The vault is stubborn.
