A rainy city street at night. As you scroll, a thief breaks into the jeweller, the street turns into a schematic map of the choices, and a getaway car leaves as the police arrive. After the film, the same street stays behind every section.
01 · After hours
StreetHeist is a risk-and-cash-out instant game for casino lobbies. Pick a storefront, see its odds, break in, and decide when to walk away.
Demo balance only. No real-money play, deposits, or withdrawals.

Safe shops pay a little. Risky shops pay a lot. After every clean break-in each door is repriced upward. Every choice moves the risk, never the 96.00% return.

The server has already fixed the outcome with a committed seed. The street only reveals it. A clean break-in multiplies the pot. A bust ends the run.

Cash out after one successful break-in, at any step, or try one more shop for a bigger multiplier. Up to 10 steps. Target RTP 96.00% holds on every route.

First break-in at the example stake, on the default math. Multipliers as the game shows them. Payouts are floored to the cent.
The spec
Choice changes risk, never the target RTP. A 5.00% opening patrol is rolled once per round and applies to the first break-in only. Later steps carry the storefront risk alone.
Per storefront, from the second break-in on
First break-in, storefront risk plus the opening patrol
Risk is the chance that one break-in fails. Target RTP 96.00% holds on every route. Settlement runs in integer cents, and whole-cent flooring means realized return can be slightly lower.

13 · The science
Engagement design, not luck. Five findings from reward research explain why a visible risk and a cash-out button hold attention. Each one comes with the control that keeps it responsible.
Δ
Most dopamine neurons fire when an outcome is better than expected, dip when it is worse, and stay at baseline when it was fully predicted.
In StreetHeist The server fixes every door before the run. The player learns it one door at a time.
Review · 2016
P = 0.5
In a study with monkeys, a sustained dopamine signal tracked uncertainty and was largest when a reward had a 50% chance.
In StreetHeist The bank is the coin flip: 50.0% risk and the biggest multiplier on the street.
Peer reviewed · 2003
2 phases
In an imaging study of 9 volunteers, anticipating a possible reward and receiving it activated different brain regions.
In StreetHeist The walk to the door and the door itself are two beats, on purpose.
Peer reviewed · 2001
$8.67 vs $1.96
People who chose their own $1 lottery ticket asked $8.67 on average to sell it back. People handed a ticket asked $1.96.
In StreetHeist The player picks every door. Choice never changes the math: Target RTP 96.00% on every route, and the sign shows the odds.

15 · Technical overview
A server-authoritative remote game server with a stateless HTML5 client. Your wallet holds the money. We hold the math and the proof.
Your back end signs a launch call with HMAC-SHA256 inside a 5 minute window. We answer with a one-time code that works once and expires after 10 minutes. Your player token never reaches the browser.
The round starts on the server: the stake is validated and your wallet is debited with an idempotent bet call. An unanswered bet is rolled back automatically.
The whole round was fixed at the start by 151 HMAC-SHA256 floats from a committed seed. Each step only reveals the next door. The client never computes an outcome.
Cash out pays through an idempotent win call. Worked example in EUR: the sign shows ×1.62, the engine keeps four decimals, ×1.6168, and 10.00 × 1.6168 = 16.168 is paid as €16.16. Rounding always favours the house by less than a cent. Every movement posts a balanced, append-only ledger entry.
After the seed rotates, anyone can replay a finished round through the public verify endpoint and check it against the commitment published before play.

17 · Straight answers
The questions operators ask first.
One title holds more than 90% of the crash category, so most lobbies carry a single hit in the format. StreetHeist is not another flight curve. It is a step-by-step ladder with a story, the format Chicken Road showed can acquire players at scale.
Not yet. Independent certification: pending. The math model is published, our own audits check the target RTP on every route and stopping rule, and every finished round can be verified. We plan certification for your markets with you.
Only through your wallet. StreetHeist never holds player funds: your cashier takes the stake and pays the win. The seamless wallet and a Hub88 adapter are built and tested against a reference casino and a Hub88 simulator. No operator is live yet, and this public site runs on a demo balance.
Small and defined. The game API is five calls: session, start, step, cash out and verify. Money moves through your seamless wallet with four signed, idempotent actions: balance, bet, win and rollback. The technical overview lists the full surface.
Yes, per deployment. The public demo runs at Target RTP 96.00%, flat on every route and every cash-out depth. RTP, stake limits and caps are set per operator within what your market allows. EUR, USDT, BTC and ETH are supported today.
