Every ranking on this site cites an “audited payout” figure. This guide shows exactly where those numbers come from, how to pull them yourself, and why a casino’s published RTP is one of the few pieces of gambling marketing you can actually verify.
State regulator filings. New Jersey’s Division of Gaming Enforcement and Pennsylvania’s Gaming Control Board publish monthly revenue reports per operator. Divide winnings paid by total wagers and you have the true payout rate — no operator cooperation required. This is the gold standard: adversarial, public, monthly.
Independent audits. UKGC-licensed casinos commission testing labs — eCOGRA most visibly — whose payout certificates are published on the operator’s site, usually in the footer. The labs are accredited and their methodology is public.
Certified reporting. Ontario’s iGaming framework requires operators to report through certified systems, with AGCO oversight. Less granular publicly than New Jersey’s model, but regulator-verified.
Three traps catch most readers. First, floor averages hide game spread: a 96.5% casino figure blends 99.5% blackjack with 92% jackpot slots. Your personal rate is your game mix, not the casino aggregate. Second, reporting periods matter: a single hot month means little; look at six-month trends. Third, RTP versions: the same slot ships at multiple certified RTPs, and the casino chooses which to license — the game’s info panel shows the live version, the review sites usually show the best one.
Rule of thumb: any payout claim that cannot be traced to a regulator filing, a lab certificate or an in-game info panel is advertising, not data.
A percentage point of payout compounds across every wager you ever place; a welcome bonus is a one-time coupon with wagering strings attached. The player who chooses a 97% casino over a 95.5% one has done more for their bankroll than any bonus code ever will. Our best payout casinos ranking applies this discipline across all three markets we audit — and the games guide shows how to raise your personal rate within any casino.
Take New Jersey’s monthly internet gaming report as the worked example. Find the operator’s “Internet Gaming Win” — that is revenue kept, not payout. Find total wagers (handle) in the accompanying detail. Payout rate = 1 − (win ÷ handle). Do it for three consecutive months and average: single months swing on jackpot luck. The same arithmetic works on Pennsylvania’s PGCB reports, and the exercise takes ten minutes with a spreadsheet — after which no affiliate site, including this one, can tell you anything about those operators’ payout you cannot verify yourself.
To make the method concrete: across the most recent quarter of public filings, New Jersey’s major online casinos clustered between 96.2% and 97.1% payout, with BetMGM’s stack consistently at the top of the band and smaller skins at the bottom. Pennsylvania ran systematically a few tenths leaner — a higher tax rate leaves operators trimming somewhere, and game mix is where it shows. The spread inside one state, top brand to bottom, was nearly a full percentage point: on £/$500 of monthly play, that is real money for choosing a browser tab. None of this required inside information; it is subtraction and division on documents any resident can download.
Payout percentage is the most verifiable number in gambling, but it is not the only one that matters. A filing tells you nothing about withdrawal friction, support quality, or how a brand behaves when a bonus term is disputed — which is why our rankings pair the filed figures with test cashouts and enforcement history. Treat payout data as the entry ticket: a brand that cannot clear the numbers bar is out before the softer questions get asked, and a brand that clears it still has to earn the rest.
Search “DGE monthly internet gaming report” for New Jersey or “PGCB revenue reports” for Pennsylvania — both publish monthly PDFs and spreadsheets on their official sites.
Often it is quoting its single best game rather than the floor average. Check whether a source is named — an unnamed “up to 98%” is marketing, not measurement.
UK regulation requires certified fair games and audited operators, but not public monthly revenue splits per brand — so lab certificates (eCOGRA, iTech Labs) stand in as the public evidence.
