Duel became the first casino ever certified by ProvablyFair.org after 53K live bets and 253M simulation rounds were independently verified as fair — the certification is fully open source and reproducible.

ProvablyFair.org launches and names Duel.com as its first certified casino

ProvablyFair.org launched with a mission to answer the one question players truly care about: "Is the game fair?" By naming Duel.com as its first certified casino, the platform set a new standard for transparency. Independent verification of 53,475 live bets and 253 million simulation rounds confirmed that Duel's games operate exactly as claimed — and the entire certification process is open-source, meaning anyone can clone the repositories and reproduce the results themselves.

The community immediately recognized this as a major trust signal. Unlike other certifications with opaque or black-box requirements, Provably Fair offers a fully auditable, code-driven verification. One player summed it up: "Lots of certifications popping up with either stupid or blackbox requirements. Provably Fair answers one question: is the game fair? Fully open source, auditable repos. Independent. Verify EVERYTHING yourself by running code."

For a player deciding whether to trust a casino, this marks a turning point. Duel doesn't just claim fairness — it hands you the keys to check for yourself. With independently verified live bets, millions of simulation rounds, and a reproducible open-source toolchain, the barrier to trust becomes almost nonexistent: the data is there for anyone willing to run the code.

ProvablyFair.org names Duel its first certified casino after 253M simulation rounds

Duel has become the first casino ever certified by ProvablyFair.org, marking a milestone in transparency after 53,475 live bets and 253 million simulation rounds were independently verified. The certification is fully open source and reproducible, allowing anyone to clone the repo and run the same checks themselves.

Community reactions highlight both enthusiasm and scrutiny. Korraflow praised the audit for answering the one question players care about—whether the game is fair—without opaque requirements. Jammy, a player with over 2,700 followers, endorsed Duel's return-to-player rates as 'insane,' especially in blackjack, and noted the platform's transparency in explaining the numbers.

However, the certification faced a measured critique from Fred Azevedo, who pointed out that a game with a max-win odds of 1 in 613.5 million spins may require more than 30 million simulation rounds for a fully rigorous audit. Despite this, the verifiable and independent nature of ProvablyFair.org's standards remains a strong trust signal for players evaluating Duel's fairness.
