Every grade starts with the UKGC public register. I record the licence number, legal entity name, and whether the operator displays it without making you dig through account menus. No valid UK licence means no listing — full stop.
Withdrawal speed comes from timed tests on verified accounts using debit and PayPal where available. I log the request timestamp, any pending-period reversal window, and when funds hit my bank or e-wallet. Marketing pages promising "instant" payouts get ignored; the cashier timestamps don't lie.
Wagering terms are read line by line. I note the multiplier, whether it applies to bonus-only or bonus-plus-deposit, max bet during play, game weighting percentages, and expiry windows. A 35x requirement on a £10 bonus is £350 in bets — I state that arithmetic because operators rarely do.
Reel Rating Room is affiliate-funded. Outbound links may earn commission. That pays for the research time; it does not buy placement. Operators cannot pay for an A grade, and I remove brands that lose UK licensing or stall withdrawals without explanation.
