How we rate online casinos

Every casino on this page gets a score out of 10. We look at the same things for each one, and we tell you how we know:

  • Payout speed: tested with our own money at the casinos in the table above. For the others, we use the casino’s published limits and independent reports, and the review makes clear it isn’t our own test.
  • Bonus terms: we read the wagering requirement, time limit, maximum bet and maximum cash-out, and explain what the bonus is really worth. Our wagering requirement calculator lets you check any offer yourself.
  • Licence and operator: who runs the casino, where it is licensed and what that means for you if something goes wrong.
  • Verification (KYC): what documents you may be asked for and when, so a withdrawal isn’t held up.
  • Games, payments and support: the providers, the deposit and withdrawal methods, and how easy it is to get help.

The full method is on our how we rate casinos page. We earn a commission when you sign up through some of our links. The order of the list on this page is set by our review scores.

About UltraGambler

UltraGambler is run by Jason Thompson, who has 20 years’ experience in online gambling, with part-time help from a small team of three. The site reviews online casinos, crypto casinos and betting sites, and explains the games and the maths behind them, from RTP in slots to roulette odds. Our free tools include an odds calculator and a gambling budget calculator.

We keep it simple: if a casino pays slowly or hides harsh terms, we say so, and when we haven’t tested something ourselves, we don’t pretend we have. Gambling should be entertainment, not a way to make money. Set a budget before you play, and if it stops being fun, our responsible gambling page lists where to get help.

Online casino FAQs

What is the best online casino?

Our top-rated casino is 1win at 9.9/10. It has a large game library, a sportsbook and a 500% welcome package over four deposits, and it paid our crypto test withdrawal in 15 minutes. The best choice for you also depends on your country, your payment method and the games you play.

Which online casino pays out fastest?

In our own tests, iWild and FortuneJack paid crypto almost instantly and 1win paid in 15 minutes. Crypto is usually the fastest method; cards can take several days. See our instant withdrawal casinos.

Do you test every casino you list?

No. We have tested withdrawals with our own money at five casinos so far (1win, iWild, FortuneJack, Tsars and Casoo), and we add more over time. Every review states whether its payout figures come from our own test or from other sources.

Are online casinos legal?

It depends on where you live. Some countries license online casinos, some ban them and some have no clear rules. Check your local laws before you sign up; our online gambling laws guide is a starting point.
