How We Score Crypto Casinos
Our scores aren't vibes. They are seven weighted criteria applied to public evidence, then summed into one number. Here is the whole method — weights, sources and limits included.
One transparent, reproducible number
Every casino we cover is scored 0–10 on seven criteria. Each criterion has a fixed weight, and the overall is simply the weighted average — sum(score × weight) ÷ 100. The scorecard widget on each page computes that live from the table below, so the headline number can never quietly disagree with the parts. That's why Duel's overall is 7.8, not a rounder, friendlier figure.
Seven criteria and their weights
Weights reflect what crypto players tell us matters: fair games and fast payouts above sponsorships, with trust kept high because this is real money.
| Criterion | Weight | What it measures |
|---|---|---|
| Fairness & transparency | 18% | Provably-fair systems, published RTP, house edge, how verifiable outcomes are. |
| Payout speed & fees | 17% | How fast withdrawals clear and what they cost. Crypto rails favoured. |
| Bonuses & rakeback value | 15% | Real, usable value after terms. No-wagering rakeback scores above locked bonuses. |
| Games & software | 15% | Library size, in-house Originals, studio coverage and live tables. |
| Trust & reputation | 15% | Licence strength, operating history, ownership transparency, public review sentiment. |
| Payments & crypto | 12% | Coin coverage, deposit options and how crypto-native the cashier is. |
| Support & safer gambling | 8% | Live support quality and the depth of responsible-gambling tools. |
| Total | 100% | Weighted average, rounded to one decimal. |
What our scores are, and aren't
What they are: our editorial assessment of each casino on each criterion, grounded in public evidence — operator terms, licence details, library data and independent reviews such as Casino Guru, casinos.org and AskGamblers. Each casino page links its own sources.
What they aren't: we do not run real-money lab tests, and we never invent ratings. Where we cite a third-party figure (a Trustpilot score, a revenue number), we say so and date it. We do not publish a star rating we can't stand behind, and we will state a casino's weaknesses plainly — Duel's low Trustpilot score and offshore licence are in our review precisely because hiding them would make the score worthless.
Why Duel isn't number one: on a like-for-like overall, bigger, older casinos out-score it on library and trust. We don't re-weight the criteria to force a result. Instead we show, round by round, where Duel beats them — rakeback, payout speed, no-KYC — in the scorecard and faceoff tool.
How we stay honest
We earn affiliate commission when readers sign up to Duel through our links, and we disclose that on every page. Commission does not buy a higher score or move a criterion — the weights are fixed and public, right here. We re-check facts periodically and stamp each casino with a "last checked" date in the data; if you spot something out of date or wrong, tell us via the contact page and we'll correct it.

Duel Casino FAQ
Do you test the casinos yourselves?
No. We do not run real-money lab tests. Our scores are an editorial assessment based on public evidence - operator terms, licence data, library figures and independent reviews - and we never invent ratings.
Are your scores paid for?
No. We earn affiliate commission on sign-ups, disclosed on every page, but the criteria and weights are fixed and public, so commission cannot change a score.
How often are scores updated?
We re-check facts periodically and stamp each casino's data with a 'last checked' date. Tell us via the contact page if something is out of date.
Why isn't Duel ranked number one?
Because on a like-for-like overall, older and larger casinos out-score it on library and trust. We do not re-weight the criteria to force Duel to win; we show where it wins round by round instead.
