What We Score
Every operator review begins with the same evidence checklist before any opinion is recorded. Editors verify the licence number against the issuing regulator's public register, audit the terms-and-conditions for wagering math, confirm the listed payment methods are actually selectable in the cashier, and test live chat response times before assigning a star rating. A casino that hides its licence, omits wagering numbers, or shows ghost payment methods is downgraded — even when its bonus headline is generous.
Licensing & Compliance
- Licence verified against the issuing authority's public register (MGA, UKGC, Curaçao, etc.)
- Responsible-gambling tools tested for visibility and function
- KYC requirements documented at sign-up

- Game weighting transparency
- Maximum cashout limits and expiry windows
Payments & Payouts

- Currency support, conversion fees, and minimum/maximum limits
- Crypto support (BTC, ETH, USDT) where applicable
Risk Signals
- History of payment disputes on independent forums
- Recent regulator warnings or fines
- Ownership group reputation and past incidents
- Customer-support responsiveness over a 5-day test window
Star Rating Scale
Our 5-star scale is calibrated so that 4.0 is the floor for any operator we recommend, and 4.8 is the highest rating we will issue. We do not award 5.0 because no commercial casino is risk-free, and a perfect score would misrepresent the inherent volatility of gambling products. A 4.0 means "licensed and operating within stated terms" — it does not endorse heavy play. Anything below 4.0 is flagged as "under review" and not promoted.
- 4.7–4.8 — Tier-1 regulator, audited RNG, clean payout record, transparent bonus terms
- 4.4–4.6 — Mid-tier regulator or newer operator with strong fundamentals
- 4.0–4.3 — Licensed and operational, but with at least one weak signal (e.g. limited payment range)
- Below 4.0 — Not recommended; flagged for re-review or removal
Conflict of Interest
Trial Bonus is an affiliate publisher. We earn a commission when a reader registers at a reviewed operator through a tracked link, and we display sponsored disclosures near every "Visit Casino" button. Affiliate revenue does not change a star rating, and we publish reviews of operators we do not earn from when their data fits our coverage scope. Editors do not hold deposit accounts at the operators they review while a review is in active development.
Fact-Check & Updates
Reviews display their most recent update date. We re-verify licence status and bonus terms for tier-1 operators on a rolling basis and refresh the wider catalogue as operator data changes. When an operator changes ownership, loses its licence, or alters bonus terms, we update the affected review and its modified date as soon as the change is confirmed against primary sources.
Corrections requested by operators or readers are evaluated against original-source evidence. Approved corrections are applied without removing the prior assessment's editorial reasoning — we explain what changed and why. Anonymous correction requests without supporting evidence are not actioned.
Responsible Gambling
Casino reviews cover the responsible-gambling tools each operator provides — deposit limits, cool-off periods, and self-exclusion — and we surface the relevant national support service for the player's jurisdiction. We do not run promotions that target self-excluded players. If you or someone you know is struggling with gambling, please contact a local helpline before continuing: BeGambleAware (UK), the National Council on Problem Gambling 1-800-GAMBLER (US), or Gambling Therapy internationally.
