The CCF Standard
What "CCF Certified" actually means
Most trust marks are just a logo. CCF is a published standard with the evidence attached. A certified casino has met all six criteria below — and where we can, we don't ask you to trust us. We show you the proof.

The criteria
Six things every CCF Certified casino must meet
Each carries an honest label, so you know what kind of evidence stands behind it:
- Tested & published — we ran the test on every certified game, and the per-test results are public.
- Tested where audited — tested and published only for the games where that audit was ordered.
- Player-checkable — where the casino offers it, players check each result themselves with our tools; CCF doesn't publish a test result for it.
- Reviewed — we confirmed the casino has it in place; the underlying evidence is seen by CCF, not published.
Fair, randomness-tested games
Tested & publishedEach certified game's RNG output is run through the published CCF-STD-001 battery (NIST SP 800-22) and must show no statistically detectable departure from randomness in the tested sample (the standard's § 10 explains what that does and doesn't prove). Every certificate links to a per-test report with exact p-values — not a checkbox — and the same battery is open to anyone in our RNG test tool. Where game logic is reviewed, we also check how the game turns random numbers into outcomes.
Game logic reviewed so far: DiceXO Dice (WC-2026-0831) — code review found an unbiased, rejection-sampled mod-10000 mapping; roll-uniformity chi-square z = −1.49. Pass.
Transparent RTP
Tested where auditedA certified game's return-to-player is declared to players. Where a CCF Labs RTP audit is part of the certification, we simulate the game's exact payout logic over 10 million+ rounds and compare the realized RTP with the declared figure — if the real payout doesn't match the claim, it doesn't pass — and the result is published. Games without an RTP audit have their RNG tested, but no RTP result.
RTP audits published so far: DiceXO Dice (WC-2026-0831) — 98.89% realized over 10,000,000 simulated rounds vs 99.00% declared. Pass.
Proven payout reserves
ReviewedFair odds mean nothing if the casino can't pay when you win. A certified casino must demonstrate control of reserve wallets sufficient to cover player balances. It proves control of those wallets to CCF by signing a message from them, and this is re-confirmed at renewal. CCF reviews the wallets; their addresses are not published. A casino that can't show the money doesn't get certified.
Player-verifiable games
Player-checkableWhere a casino offers provably-fair ("check-it-yourself") games, players can confirm each result themselves without trusting anyone. It's the one model that removes trust entirely, and we give players the tools to check.
Responsible gambling
ReviewedThe casino provides real player-protection tools — deposit, loss and time limits, self-exclusion, reality checks — and clear links to independent help resources. Fair games are not the same as safe gambling, and a certified casino has to take that seriously.
Accountable operator
ReviewedA named operating entity, a support channel that actually answers, and a public complaints process the casino is subject to. Fully anonymous is the shape of an exit scam; certification requires someone to hold accountable.
Why the labels matter. Anyone can print a badge. Criterion 1 is tested and published for every certified game; criterion 2 is tested and published where an RTP audit was done. Those results you never have to take on faith — the per-test numbers are public. Criterion 4 means players can check provably-fair results themselves with our tools. Criteria 3, 5 and 6 are reviewed by CCF, and we label them that way rather than dress them up. Certification is per-game and current: if a certificate lapses or a criterion fails, the public register reflects it.
What the CCF Standard doesn't cover: gambling licensing. CCF does not assess whether a casino holds a gambling license, and CCF certification is not a license — it authorizes operation in no jurisdiction. Check licensing separately, as step 2 of our player checklist explains.
