An independent, game-by-game audit of all 10 in-house games on Duel.com, each rebuilt from its published specification and tested against the ProvablyFair framework. All ten games met the certification criteria. Every result and finding is reproducible — the framework and per-game audits are open source, so the work can be re-run rather than taken on assertion. This page summarises results across all games; open any game for its complete audit, or read the Executive Summary for the full methodology.
Audit Verdict
The five areas below are the scored core of the audit — determinism, RNG integrity, live-verifier parity, RTP, and fairness integrity. Each was tested independently against captured live play, large-scale simulation, and a fixed matrix of adversarial probes. All five passed.

Each row is one game's result at a glance; click through for that game's complete, independently reproducible audit — methodology, datasets, simulation logs, and verifier code.
ProvablyFair.org Audit Process
Every ProvablyFair.org certification applies this process independently to each game in scope. Duel's engagement ran from March to May 2026, with games completing the framework in parallel.
Transparency and Verification
Every audit ships as code in its own per-game repository. Clone, install, and re-run the full audit pipeline — datasets, simulations, and verification logic included.
