How it works

Open Logic.
Publicly VerifiableResults.

Our audits validate fairness without disrupting operations or exposing sensitive systems.
You provide
  • A clear breakdown of game logic (e.g. RNG method, seed usage, outcome resolution)
  • Seed structure and fairness implementation details
We simulate and test externally
  • Run 100,000+ rounds using your logic
  • Compare simulated outcomes with real gameplay via a public player account
  • Validate randomness, output accuracy, and RTP alignment
This delivers
  • No impact on live systems
  • No exposure of proprietary backend or codebase
  • An audit that's transparent, reproducible, and independently verifiable
What we audit

Our 8-Point Fairness Framework

Randomness alone isn’t enough; true fairness requires transparent outcome mapping, payout calculation, and user ability to verify expected returns.
01
RNG Algorithm Transparency

The random number formula must be published, open, and cryptographically secure.

02
Seed Architecture Integrity

Uses separate player and casino seeds with nonce for unique outcomes.

03
Server Seed Commit-Reveal

Casino must lock in server seed with a hash before gameplay starts.

04
Game Logic Reproducibility

Anyone can reproduce the outcome step-by-step from RNG to final result.

05
Round-by-Round Verifiability

Every game round can be verified later using original seed data.

06
Client Seed Customization

Players can set or randomize their own seed to ensure fairness.

07
Public Verifier Tool

Anyone can verify results using an open, transparent tool or script.

08
RTP & Edge Declaration

Declared house edge must match long-term outcomes from large-scale simulations.

Certification outcome

Only Fully Audited Casinos
Are Certified

Certification is awarded only when a casino meets all audit requirements - across game logic, fairness implementation, and testing validation.

If anything is incomplete or unclear, we provide:

  • A clear report outlining exactly what needs to be addressed
  • Technical guidance to meet the certification criteria
  • Complimentary retesting once updates are in place
