What is covered
The same certified RNG serves every 155.io game — crash, the counting/CCTV games and the classic marble games alike. It is a single shared component, so there is no per-game or per-title variation in how outcomes are drawn, and the certificate identifies the certified build by checksum.
What was tested
RiskCherry audited the RNG source and independently tested a 10 GB sample of raw generator output, generated under sustained maximum load on production-equivalent hardware.
Every assessed property — entropy source, unpredictability, cycling, seeding and reseeding, degrees of freedom, scaling and security — was returned Compliant, and the sample passed the standard statistical test batteries with no failures. The entropy source is the operating system's CSPRNG.
How this relates to provable fairness
The two are complementary. Provable fairness proves a round's outcome matches a commitment published before betting closed. Certification proves the underlying randomness is sound in the first place — something provable fairness cannot establish on its own.
