How We Calculate Trust Score

Trust Score is the single number we attach to every operator we list — a 0–10 rating that's meant to answer one question at a glance: how much should you trust this site with your money? It looks simple on the page, but it's built from fifteen separate scored dimensions, not a single editor's gut feeling, and we think it's worth explaining exactly how it works rather than asking you to take it on faith.
What actually gets scored
Every operator we track has an internal record — operator_trust_metrics — with a 0–10 score for each of fifteen dimensions. An analyst updates these as new evidence comes in: a license renewal, a wave of withdrawal complaints, a bonus term that turns out to be misleading. None of them are guesses; each is tied to something we can point to — a regulator's public register, a payout time we've verified, a support ticket we've seen resolved (or not).
The fifteen dimensions aren't weighted equally. We think some things matter more to whether your money is safe than others, so the formula reflects that:
- License standing (weight 2.0) — the single heaviest factor. An active, unrestricted license from a real regulator is the baseline everything else builds on; a suspended or lapsed one drags the whole score down hard, regardless of how good the site otherwise looks.
- Payment reliability, withdrawal speed, complaint response (weight 1.5 each) — the three things that determine whether you actually get paid, and how much friction you go through to get there.
- Transparency, security, responsible gambling tooling (weight 1.0 each) — how clearly the operator states its terms, how it protects your account and funds, and whether it gives you real tools (deposit limits, self-exclusion, reality checks) rather than a token link in the footer.
- Support quality, bonus fairness (weight 0.75 each) — how good the operator is when something goes wrong, and how honest the fine print on its promotions actually is.
- Affiliate reputation, mobile experience, website quality, KYC friction, country availability, crypto support (weight 0.5 each) — smaller factors individually, but they still move the needle, especially for operators that are close to each other on the heavier criteria.
How the number is actually calculated
Trust Score is a weighted average, not a sum — an operator isn't penalized for a metric we simply haven't recorded yet, only for one that's been recorded and scored poorly. Concretely: we multiply each recorded score by its weight, add those together, and divide by the total weight of everything actually recorded for that operator. If we've only logged five of the fifteen dimensions so far, the score reflects those five — it doesn't silently assume the missing ten are perfect, but it also doesn't punish the operator for data we haven't gathered yet.
That's also why you'll occasionally see a Preliminary tag next to a Trust Score on this site: it means the number is real and calculated the same way as any other, but the operator doesn't have a written editorial verdict yet — we'd rather show you an honest, data-backed preliminary score than hide it until the full review is finished.
What the score actually means in practice
Roughly, here's how to read it:
- 8.5 and above — an active license in good standing, no material unresolved complaints, and bonus terms we'd consider fair and clearly stated.
- 6.5–8.4 — solid on the fundamentals, with one or two softer spots — maybe slower withdrawals than we'd like, or support that's adequate rather than excellent.
- Below 6.5 — usually means we've found something specific worth flagging: a license under review, a pattern of complaints, or bonus terms we think are designed to confuse rather than inform. We'll always say what it is in the operator's editorial verdict, not just show a low number and leave you guessing.
When scores change
There's no fixed review schedule. A score updates the moment new evidence changes one of the fifteen underlying metrics — a license gets suspended, a withdrawal complaint gets resolved faster than usual, an operator quietly tightens its bonus terms. That means two operators with the same score today can diverge tomorrow if one has a regulatory action and the other doesn't. We log every change to an operator's public change history, so you can see not just the current number but what moved it.
Trust Score is deliberately not the same thing as "the operator we'd personally recommend" — a site can score well on every dimension we track and still not be the right fit for how you play (unavailable in your country, no crypto support, a game library that doesn't suit you). Treat it as a floor, not a ceiling: a strong score means we haven't found a reason not to trust the operator with your money, not that it's automatically the best choice for you specifically.
