Written from the supplier's side of the table, including the parts that are slower and more expensive than the pitch decks suggest. Seven steps, in the order they actually happen.
An online casino is two businesses wearing one brand. The first is a regulated financial operation: identity checks, money movement, record-keeping and a regulator who can end it. The second is a consumer entertainment product competing for attention against everything else on a phone.
Most launches fail on the first because founders budgeted only for the second. The technology is the most predictable part of the whole exercise — licensing, payments and player acquisition are where timelines slip and money goes.
That framing is why this guide starts with market and licence rather than with platform selection.
Everything downstream — licence, payments, game mix, responsible-gambling rules, even permitted bet sizes — is decided by where you intend to accept players. Pick the market first and work backwards. Operators who choose technology first almost always rebuild something later.
You need one. No technology supplier can licence on your behalf, and any supplier suggesting otherwise is a problem in itself. Curaçao and Anjouan are common entry points; Malta and the UK are substantially more demanding and correspondingly more credible. Budget months, not weeks, and expect corporate structure, fit-and-proper checks and a compliance plan to be part of it.
Almost nobody should build a wallet, an RNG and a compliance engine from scratch — the engineering is unglamorous and the certification burden is severe. The realistic decision is which supplier, at which layer: full turnkey, white-label platform, remote gaming server for content, or a mix.
Payment acceptance is usually the hardest commercial problem a new operator faces, and gambling merchant accounts are not easy to open. If you intend to take cryptocurrency, understand that you are taking on custody of bearer assets — key management, sweeping and solvency reporting are engineering problems, not payment problems.
With a modern SDK this is the fastest part, not the slowest. Slotty Labs' TypeScript SDK handles single sign-on and game embedding in roughly twenty lines; the longer pole is usually your own site, CRM and payment plumbing rather than the game integration itself.
Your regulator will want evidence about the games and the platform: RNG design, math models, RTP verification, audit trails and responsible-gambling controls. This is far easier when the supplier has assembled the package in advance rather than starting it when you ask.
Run the sandbox hard — forced outcomes, disconnect handling, webhook failure, withdrawal edge cases. Sandbox-to-live is typically one to two weeks once integration is done. Launching before you have tested a mid-round disconnect is how support queues are born.
The compliance engine, permitted features and bet limits all follow from the jurisdiction. Picking a platform first means discovering later that it cannot be configured for where you actually want to operate.
Founders routinely budget six figures for platform and nothing for the months of work required to get reliable deposit and withdrawal rails in their target market.
Evidence about RNG design, math models and audit trails takes time to produce. If your supplier starts assembling it when you ask, you have already lost a quarter.
Double-entry accounting, idempotency, balance locking and reconciliation are deceptively hard, and getting them subtly wrong surfaces as money discrepancies you cannot explain to a regulator.
Slotty Labs supplies the technology layer: five original games on our own remote gaming server, a double-entry wallet with native crypto custody, a per-jurisdiction compliance engine, and an operator back office — integrated through one TypeScript SDK.
We do not hold or provide gambling licences, we are not a casino, and players never see our brand. Your licence, your brand, your players, your front-end.
What we do bring to your submission is evidence: a GLI-19-aligned architecture, written math models with 10,000,000-round Monte Carlo verification per RTP variant, a NIST SP 800-90A RNG with continuous self-tests, and hash-chained audit trails — assembled as a dossier package before you need it.
npm install @slottylabs/sdk.Yes. Operating real-money gambling without a licence is a criminal matter in most jurisdictions. Technology suppliers, including Slotty Labs, provide the platform and the certification evidence for your submission — never the licence itself.
It varies enormously by market, and anyone quoting a single figure is guessing. The cost centres are consistent though: licensing and legal, platform and game licensing, payment processing, compliance staffing, and marketing — which for most new operators is by far the largest and most underestimated line.
Licensing dominates the timeline and is measured in months. The technology integration is comparatively quick — SDK integration typically under a day, sandbox-to-live usually one to two weeks — so plan around the regulator, not the developers.
White-label means you launch your brand on a supplier's platform. Turnkey typically bundles more operational support around that. In both cases the licence obligation remains yours.
In many jurisdictions yes, subject to the regulator's position and your AML programme. The technical requirement is real custody infrastructure — HD deposit addresses, sweeping, key management and solvency verification — rather than a payment widget.
They should not. With Slotty Labs, players are created automatically on first game launch, keyed to your own player IDs. Your brand, your player relationship, your data.
We will tell you honestly what is realistic, including when we are the wrong fit. Sandbox keys are available for evaluation.
