Sudonex publishes long-form technical writing for the people who actually build and operate iGaming products — CTOs scoping a casino, mathematicians tuning a slot, product owners arguing with a payment provider. The pieces below are not blog filler. They are the references we send to clients when a question comes up for the third time.
Casino platform building
Casino app development guide walks the full stack — lobby, wallet, KYC, bonus engine, aggregator integration — with the architecture trade-offs explained. How to build an online casino is the same territory framed for operators rather than engineers, including licensing, vendor selection, and time-to-launch realities. Casino software cost guide breaks down what you actually pay for: licences, platform build, integrations, certification, and ongoing operations.
Slot games
Slot game development guide covers the lifecycle from concept to certification. Slot game RNG explained is a technical write-up of pseudorandom generation, entropy sources, and what RNG labs check during certification. Slot game math and RTP walks return-to-player calculations, hit frequency, volatility tuning, and the mathematics behind a balanced paytable.
Sports betting and exchanges
Sports exchange vs sportsbook explains the difference in matching engine, liability model, and player economics. How betting exchanges work is a technical deep-dive on lay/back matching, commission, and partial fills.
Operations, integration, security
iGaming maintenance best practices covers what good observability, incident response, and reconciliation look like in production. Casino security guide covers OWASP-aligned threat modelling, wallet security, session hardening, and bonus-abuse prevention. iGaming API integration guide covers aggregator protocols, idempotency, retry semantics, and the failure modes nobody warns you about. Payment gateway for casino covers PSP selection, settlement reconciliation, chargeback handling, and crypto on-ramps.
Planning
iGaming MVP guide is the playbook we use with funded startups — what to cut, what to keep, and how to ship inside a runway.
If there is a topic missing here that you wish we had written about, tell us. We write what operators ask for.
How to use these resources
These pieces are written for a working audience — a CTO scoping a build, a mathematician tuning a paytable, a product owner mid-argument with a payment provider — so they assume you want the mechanism, not the marketing. If you are early in planning, start with the operator-framed overviews (how to build an online casino, the cost guide, the MVP guide) to get the shape of the decision. If you are deep in a specific problem, go straight to the technical deep-dives on RNG, exchange matching, API idempotency or wallet security. Each guide is self-contained but cross-links to the related service or solution when you are ready to move from reading to building.
How this library is written and kept current
Nothing here is spun filler or a keyword exercise. Each piece is the reference we already send clients when a question comes up for the third time, written by the engineers, mathematicians and compliance specialists who do the work. That means the guides carry the same opinions we bring to an engagement — that you build for the audit first, that honest scoping beats optimistic timelines, that ownership beats a per-spin tax. When a regulator standard shifts, a certification lab changes what it checks, or an aggregator protocol updates, we revise the affected guide rather than leaving stale advice in place. The topics track what operators actually ask, which is why the library grows in the direction of real questions rather than search volume.
What to read next by role
Founders and operators pre-launch get the most from the MVP guide, the cost guide and the how-to-build overview, in that order. Engineers inheriting or building a platform should start with the API integration guide, the security guide and the maintenance best-practices piece. Studios and game teams belong in the slot development, RNG and math-and-RTP trio. Anyone evaluating exchange work should read the sportsbook-versus-exchange comparison before the matching deep-dive. If the topic you need is missing, tell us — the next guide is usually the one a client asked for last.
