About this ranking
IndexFair rates US online casinos on a four-block composite score: regulatory standing, user-experience signals from public reviews, cross-source consistency, and measured product metrics. US online casino gaming is licensed state by state, so the ranking is national — each casino earns one score, computed once against the full US cohort — while each state page lists only the operators licensed in that state. Scores are methodology-derived, with no affiliate-influenced placement; brands cannot pay to change their score. Operators below the sample-size threshold are listed without a published score rather than a low-confidence number; coverage expands as more operators qualify.
How IndexFair scores brands in this market
Each US casino score combines four blocks: regulatory standing (the state licence and the regulator's enforcement record), user-experience signals aggregated from public reviews, cross-source consistency, and measured product metrics read from the live product. The user-experience block applies time-decay and Bayesian shrinkage so low-volume periods do not whipsaw the score. The published block weights are recorded at /methodology and move only with a versioned methodology change — they are not hardcoded here, so this page never drifts from the live model.
Scores are national and market-relative: every casino is ranked against the other licensed US casinos rather than on an absolute scale. A state page does not re-rank — it filters the national ranking to operators licensed in that state, so a brand's number is identical on the national page and on every state page where it appears.
Frequently asked
How does IndexFair rate US online casinos?
+−
IndexFair computes a composite score per casino brand over four blocks: regulatory standing, user-experience signals from public reviews, cross-source consistency, and measured product metrics. Inputs come from state-regulator records and public review aggregators. The ranking is national — one score per brand, computed against the full US cohort. The full formula, including the current block weights and the time-decay and Bayesian-shrinkage transforms, is published at
/methodology.
Are IndexFair casino scores specific to my state?
+−
No. Each casino earns a single national number, computed once against all licensed US casinos. A state page does not re-rank — it filters that national ranking to the operators holding a licence in that state. A brand's score is therefore identical on the national page and on every state page where it is available; the state view changes which brands are listed, not their numbers.
Why do some casinos show a 'Rating pending' badge instead of a number?
+−
A brand publishes a number only once it clears the sample-size threshold — an effective sample of at least 30 after time-decay. US coverage is expanding; operators below the threshold are listed without a published score rather than shown a low-confidence number that a small sample cannot support. The brand appears with a number once enough recent signals accumulate.
What is the difference between licensed and offshore casinos?
+−
A licensed US casino holds an active operating licence from a state regulator. Offshore casinos accept US customers without state authorisation, which is unlawful in regulated states. IndexFair lists only licensed operators in its state and national casino rankings. Offshore brand pages, where present, carry a risk disclosure rather than a methodology score and are excluded from rich-snippet rating output, so they are not surfaced in search as endorsed.
How is withdrawal speed reflected in the score?
+−
Withdrawal-speed signals come from two sources: regulator data, where a state authority has published action tied to withdrawal delays or fund-segregation issues, and aggregated review signals from consumer reports across the public source set. The user-experience block weights these against the methodology's published time-decay, so older reports do not outweigh recent behaviour. Brand pages surface the aspect-level breakdown, including withdrawal speed, where the data is sufficient.
Site-wide policy
Confidence intervals (±0.x) reflect sample variance and effective sample size — wider intervals mean smaller samples or higher divergence between sources, not lower brand quality.
IndexFair does not display affiliate-influenced rankings and currently places no affiliate-tagged outbound links on rating surfaces. The editorial-independence firewall at /policies/firewall lists brands where a founder commercial relationship is disclosed and firewalled in code; for those brands the methodology score is still published. Scores are not operator-editable; factual disputes route through /privacy/contact, and every methodology change is dated and reversible at /changelog.
Can a casino pay to improve its IndexFair score?
+−
No. IndexFair does not accept payment from operators for placement, ranking, score modification, or featured listing. Rank is not for sale. The editorial-independence firewall at
/policies/firewall lists brands where the founder has a commercial relationship; for those brands the methodology score is still published, and IndexFair places no affiliate-tagged outbound links. The firewall is enforced at the database level and audit-logged on every change.
What does the ± confidence interval mean?
+−
The ±0.x bracket alongside a score is a 95% confidence interval derived from sample variance and effective sample size after time-decay. A score of 7.4 ± 0.3 reads as 95% confidence that the true value lies in 7.1–7.7 given current evidence. Wider intervals indicate smaller samples or higher divergence between sources, not lower quality. Brands below the effective-sample threshold of 30 decline to render a number at all and show a 'Rating pending' badge instead.
How often are casino scores updated?
+−
Scores recompute on a schedule and again when new review data lands between scheduled runs. Every brand card shows its own last-recomputed time. Real-time updates are not offered — the cadence avoids over-weighting transient sentiment spikes. Methodology changes themselves are versioned and dated at
/changelog.
