How we rate casinos
Every trust score on Frankly is calculated from a formula, not editorial opinion. Five factors, weighted by importance, produce a single number from 0 to 10.
We publish the formula so you can verify any score yourself. If a casino scores poorly, you can see exactly why. No casino pays for a higher score or preferential ranking.
Trust Score = Licence (0–2.0) + Complaints (0–2.0) + Withdrawal (0–2.0) + Fairness (0–2.5) + RTP (0–1.5)
Maximum possible score: 10.0 · Minimum: 0.0 · Recalculated on every data change
Licence & Track Record
We verify every casino's regulatory licences against official public registries — but the licence is a starting point, not the whole picture. A strong regulatory regime matters, but so does the operator's actual track record: how long they've been running, how they handle complaints, and whether they've survived scrutiny at scale. A Curaçao casino operating reliably since 2017 is a different proposition from one that launched last month. Longevity earns a bonus because time is the hardest test to fake.
Complaint Resolution
We read each casino's record at an independent complaint mediator. What counts is how decided complaints ended: those resolved against those left unresolved. A complaint the mediator rejected as unfounded, or one still open, counts neither for nor against. A casino with 90%+ resolved scores full marks; fewer than five decided complaints is too few to score and takes the standard 1.6.
Withdrawal Speed
How quickly can you actually get your money? We track reported withdrawal times. Same-day payouts score the maximum. Anything over 5 days is penalised heavily.
Bonus & T&C Fairness
This is where Frankly goes deeper than anyone else. Wagering is the hidden cost of every bonus, so we work out what it takes to clear $100 of bonus — the multiplier and what it applies to (bonus only vs deposit + bonus) — and place that on the Frankly index of every live welcome bonus. A bonus at the index median scores 1.5: standard terms are not a penalty. Sticky structure, cashout caps, short expiry and zero table or live contribution cost points; non-sticky earns one. Every bonus is placed on the Frankly bonus index rather than an industry figure: across 28 live welcome bonuses (November 2026) the median wagering is 40x, and clearing a $100 bonus takes a median $4,000 of turnover (quartiles $4,000–$4,500). A bonus around that median is standard; sticky or deposit-inclusive terms are what cost more.
RTP Transparency
Does the casino publish Return to Player percentages? A casino that runs its own provably fair games, where every bet can be verified on its site, scores the maximum; a few third-party provably fair titles in a slots lobby don't count. Per-game RTP data gets strong credit. A general average gets partial credit. No RTP data published scores zero.
What we don't do
No paid rankings
Casinos cannot buy a higher position. The formula determines order.
No editorial overrides
We don't manually adjust scores. If the data changes, the score changes.
No hidden factors
Every component of the score is documented on this page. Nothing is secret.
