Our Scoring Methodology

The PSI score is built from four weighted components: licensing, payment testing, support response, and terms transparency. This page breaks down exactly how each component is measured, because a scoring system nobody can inspect isn't worth much more than a marketing badge.

Licensing Component

Licensing carries the heaviest weight in the model. We check the licence number directly against the issuing authority's public register — MGA, Curaçao, Gibraltar, or otherwise — rather than accepting a casino's own claim. A licence that can't be verified independently scores at the floor regardless of anything else the casino does well.

Payment Testing Component

Every casino not on GamStop in our index has had a real deposit made and a real withdrawal requested, timed from request to funds landing. We test at least two payment methods per casino where available — typically one card or bank method and one crypto method — since withdrawal speed often varies significantly between the two at the same casino.

Support Response Component

We contact support with a realistic account-related question and record actual response time, separately for live chat and email where both exist. A casino with strong licensing and fast payments can still score poorly here if support is slow or unhelpful, and we think that's the right outcome — support quality is a real part of the player experience.

Terms Transparency Component

We check whether withdrawal limits, wagering requirements, and complaints processes are stated clearly and are easy to find, not buried in a lengthy terms document or omitted entirely. Casinos that disclose this information upfront score higher than those that require digging or direct contact to find it.

How the Final Score Is Calculated

The four components are weighted, not averaged evenly — licensing counts for the largest share, followed by payment testing, with support and transparency splitting the remainder. A casino not on GamStop with excellent support but weak, unverifiable licensing will still score low overall, because no amount of good support offsets a licensing problem.

How Often Scores Are Updated

Non GamStop casinos change ownership, licensing, and payment providers more often than UKGC-licensed sites tend to. We re-test rather than assume a score stays accurate indefinitely, and a casino that stops responding to support tickets or starts delaying withdrawals will see its score drop at the next review cycle, not stay frozen at its original rating.
