Verified, not invented
Every number below comes from official government licence registers and our own published reviews — nothing is estimated.
How every listing earns its place
Three rules, no exceptions — the same method behind every page on this site.
1 · Register-checked
Every brand is matched against its country's official licence register — UKGC, Brazil's SPA, iGaming Ontario, Spain's DGOJ and more. No licence in your country, no listing.
2 · Scored on a public rubric
Ratings follow our published methodology — odds value, payments, support, licensing weight. Commercial relationships never change a score or a ranking.
3 · Kept current
Registers change and bonuses change. Pages are rebuilt when the source data changes, and every review states what it is based on.
Official licence lists, by country
We publish the full list of legally licensed betting sites for 18 markets, built directly from each regulator's own register.
Learn before you bet
153 plain-language guides — how odds, bonuses and payouts really work, with no sales pitch.
Bankroll management & staking
The one skill that outlasts any bonus: how to size bets so a bad week never empties the account.
Bookmaker margin (vig) explained
Why 50/50 pays less than 2.00 — and how to spot the books that take the smallest cut.
Casino bonus types explained
Deposit matches, free spins, cashback — what each one is really worth after wagering rules.
Questions we get asked
How does Gamblerfy verify that a betting site is licensed?
Every brand is checked against the official licence register of each country — the UK Gambling Commission, Brazil's SPA, iGaming Ontario, Spain's DGOJ and 14 more. If a brand is not on the register for your country, we do not list it there.
Do operators pay to improve their score?
No. Scores follow a published rubric and commercial relationships never change a score, a ranking, or which brands appear. Affiliate links are disclosed on every page where they exist.
Why do I see different bonuses than someone in another country?
Licences and welcome offers are country-specific. Gamblerfy detects your country and shows only brands and offers that are legally available where you are.
Is online betting legal in my country?
It depends on your country's regulation. Our country pages list only brands verified against that country's official register — if a country has no licensed online market, we say so instead of listing offshore sites.
