Each site goes through the same sequence. Register with a standard email and note every mandatory field. Check whether the signup flow references GamStop or any self-exclusion register. Deposit at or near the site's minimum.
Then play a fixed set of titles to confirm the advertised studios are present, request a withdrawal and time it from request to arrival, and record what documents were asked for and at what balance.
An operator-supplied account behaves differently from a real one. Verification gets skipped and withdrawals get prioritised, so a test run on one measures a path no ordinary player takes.
Funding every account personally makes testing slower and more expensive. It is the only way the payout times here reflect what a reader will actually experience.
The order is commercial and is labelled as such under every list. The measured values are not commercial and are not adjusted.
A site that disappoints keeps its position and carries the finding. One operator in the current lineup blocks UK access entirely; it stays listed with that stated, because removing it would hide a fact a reader needs.
