Games players love. Tech you can prove.

Slotty Labs is a game factory, an aggregator, a turnkey casino builder and a blockchain studio. Twelve originals in the lobby. A provably-fair engine underneath. One team behind all of it.

Slotty Labs

We make games. Then we make sure you can prove every one of them is fair. Everything else we build — the aggregation layer, the turnkey casino, the blockchain work — grows out of that same engineering, the same team and the same standard of evidence.

What we do

One studio. Four ways to launch.

Pick one, or all four. Every service runs on the same engine, the same wallet and the same team — so whatever you start with, the rest plugs straight in.

Games

Originals. Made to order.

Twelve originals ready for your lobby today — a slot, a crash game, cash-out games, ladders, a launcher and more. Or a custom game built for your brand: your theme, your math, your mechanics.

Aggregator

One integration. A full lobby.

Plug in once and serve games through a single API, a single wallet connection and a single contract — our originals and the studios we integrate for you, side by side.

Turnkey

Your casino. From zero to live.

Brand, website, player accounts, wallet and crypto payments, games, compliance and back office — designed, built and launched for you. You bring the licence. We bring everything else.

The platform

Everything behind your casino.

You bring the brand, the licence and the players. We bring everything they never see — and everything the auditor will.

Game factory

Twelve original games.

Your lobby is full on day one — twelve originals with provably-fair verification, math your compliance team can file as-is, and no aggregator in the middle taking a cut.

Explore the games →

Wallet & crypto custody

A player deposits USDT at 3 a.m. and nobody wakes up: the chain confirms, the balance credits, the funds sweep. Every cent provable to anyone who asks.

The wallet stack →

Compliance engine

Your market's rules enforced by the platform, not by memos. A non-compliant bet never reaches the game — and the GLI-19-aligned evidence is already prepared.

Certification readiness →

White-label admin panel

Approve withdrawals with the player's whole story on screen, launch bonus campaigns and watch GGR move in real time — all under your logo.

Operations tooling →

Security architecture

Passkeys, un-forgeable 30-second launch tokens and tenant isolation enforced by the database itself. A compromised front-end still can't touch another player's money.

Security details →
Developers

About 20 lines of TypeScript.

That's what stands between your website and a running casino. Your backend team will ask what the catch is. There isn't one — @slottylabs/sdk, zero dependencies, one launch token, one webhook stream.

Developer experience →
launch-game.ts
import { SlottyClient } from '@slottylabs/sdk'; const slotty = new SlottyClient({ apiKey, webhookSecret }); const { launchToken } = await slotty.auth.createSSOToken({  playerId: 'your-player-id',  currency: 'EUR',  jurisdiction: 'MT',}); const url = slotty.games.getLaunchUrl('slotty-slots', launchToken);// → embed in an <iframe>. That's the integration.
How it works

From contract to live casino.

Four steps. The slowest one is usually your paperwork.

Full developer walkthrough →
01
Same day

We provision your casino

Your tenant is created on our platform: game portfolio with per-game RTP variants, jurisdiction rule-set, branded admin panel and a sandbox API key. Multi-tenant with database-level isolation — your data is structurally yours.

02
Typically under a day

Your developers integrate

Install the SDK, request a launch token when a player clicks a game, embed the URL. Players are created automatically at first launch, keyed to your player ID — no migration, no duplicate sign-up.

03
Sandbox

Test on production infrastructure

The sandbox is the production stack in test mode: players with any balance, forced game outcomes for deterministic QA, webhook test events and integration health checks.

04
1–2 weeks total

Go live

A 7-step onboarding checklist tracked in the platform, our integration review, then your production key. Go-live is literally swapping one string in your config.

Proof, not promises

The numbers the lab will check.

In this industry, “trust me” loses deals. Here is the evidence instead.

Up to 10M
Monte Carlo rounds per RTP variant¹

6
EVM chains with live USDT/USDC custody
4
RTP variants per game (92/94/96/97%)

Aligned architecture, evidence package prepared

Core SSO + game-embed integration

¹ Up to 10M rounds per variant; skill/stopping games quote best-play RTP; physics games use proportionally sized simulation.

Fair by construction

Three layers of proof. On every round.

Anyone can say “fair”. We built it so nobody has to take our word for it — not the lab, not the regulator, not the player on a losing streak.

01

NIST-standard RNG

HMAC-DRBG per NIST SP 800-90A — 256-bit strength, multi-source entropy and forward secrecy, with a statistical test battery designed per NIST SP 800-22. Process-isolated: games reach it only through an internal RPC interface.

02

Simulation-verified math

Every RTP variant is a separately calculated math model, verified with Monte Carlo RTP evidence against the theoretical model. The result files are part of the certification evidence package.

03

Provably-fair verification

Available per operator across all twelve games: a seed is committed before each bet and every outcome is verifiable in-game or on our public verification page, using native Web Crypto.

FAQ

Questions, answered.

Yes — Slotty Labs provides the technology and the certification evidence for your submission, not the license itself. The platform's jurisdiction engine is configured to your market's rules.
The RNG implements NIST SP 800-90A (HMAC-DRBG, 256-bit strength) with multi-source entropy and a statistical test battery, and a certification evidence package is prepared. Formal lab certification is planned as part of your market entry. Provably-fair verification is available per operator across all twelve games, with an in-game panel and independent in-browser verification page. The evidence package is designed so accredited labs (GLI, BMM, eCOGRA) can start immediately.
Three layers: published math models, Monte Carlo RTP evidence per variant verified against theoretical models, and live RTP monitoring in production with deviation alerts. Provably-fair verification is available per operator across all twelve games: a seed is committed before each bet, and every outcome is independently verifiable on our public verification page.
No. Players never see us — they're created automatically on first game launch, keyed to your ID. Your brand, your player relationship, your data.
USDT and USDC on EVM chains (Ethereum, BSC, Polygon, Arbitrum, Base, Avalanche), with Bitcoin, Solana and Tron support built and in provisioning. Deposits are detected on-chain and credited automatically; gas is sponsored and budget-controlled per operator.
Core SSO + game-embed integration typically under a day with our TypeScript SDK. Sandbox-to-live including webhooks and review is usually 1–2 weeks depending on your side's pace.
Every real-money round is persisted and reconstructable for dispute resolution — we can reconstruct exactly what happened, outcome by outcome, and tied to the exact game version that produced it.
Yes. Our game factory builds exclusive originals and branded editions of our titles — theme, art, math and mechanics — and ships them the way we ship our own: a written math model, Monte Carlo RTP evidence per variant and provably-fair verification.
Yes. With our aggregation service you integrate once — one API, one wallet connection, one contract — and serve our originals alongside the third-party studios we integrate for your lobby. If you already work with an aggregator, our originals can go live through it too.
Yes. Turnkey means we design, build and launch your casino from scratch: brand, website, player accounts, wallet and crypto payments, games, compliance tooling and back office. You hold the gambling licence; we provide the technology and the certification evidence.
Yes. We build custom blockchains, smart contracts and dApps — tokens, NFTs, staking and vesting, treasury and multisig tooling, on-chain games and the front-ends that use them.
