THE RNG PILLAR
RNG — the complete guide
Every certified casino game rests on a random number generator, and almost nothing written about them is both neutral and correct. This pillar is a living textbook: how RNGs are built, what the test batteries actually prove, what a certificate asserts and omits, the documented cases where certified generators failed, and what the cryptography of “provably fair” really guarantees — each claim cited to a primary source. Independent, cited, and free — no casino links, ever.

What’s coming
Planned — this pillar grows a chapter at a time, each verified before it ships.
- Live dealer vs RNG — Where the randomness comes from in live-dealer games, and how that differs from an RNG title.
- RNG in crash games — How crash and originals generate outcomes, and what 'provably fair' does and doesn't cover there.
- Hardware RNG in practice — How hardware entropy sources are actually used, conditioned and health-tested in gaming systems.
- Seeding and state attacks — How generators are seeded, and the classes of attack that target seed and internal state.
- Anatomy of a test battery — What each statistical test in a standard RNG battery is actually looking for.
