Our Vetting Process

How can we be so confident that you’ll be safe by playing for real money at our recommended best online casinos? The secret lies in our stringent vetting process. We know that our recommendations can also impact our reputation, so we’re careful to ensure that each and every casino site we suggest is safe and trustworthy, and offers a quality gaming experience for players.

In order to be as certain as possible about our best casino sites, we take a look at numerous factors when evaluating each site. These generally break down into a few categories: items related to safety and ensuring the sites are legitimate, the quality of the games you can play, and the efforts made by operators to give players the best experience possible.

Of course, it’s a bit more complex than that. Read on to learn more about how we figure out which sites make it to our list of best rated online casinos, and which ones should be avoided at all costs.

Licensing and Regulation

There’s still a perception by some politicians and gamblers alike that the internet gambling industry operates in a “Wild West” environment where there are no rules, restrictions or regulations. In reality, virtual casinos are quickly accepting oversight similar to their land-based counterparts. All reputable sites are regulated in at least one established jurisdiction that serves to provide oversight and consumer protection for players.

Increasingly, many countries, provinces, and states are requiring local licenses in order to operate. If you live in one of these areas, we’ll let you know which sites are approved by your local government – and others that might still operate there outside of that system.

Malta Gaming Authority

Malta Gaming Authority

Year established: 2001
Licensed operators: 450+
The Malta Gaming Authority (MGA) is one of the most respected gambling commissions globally. Its mission objectives include creating a safe environment for online gamblers and keeping the iGaming industry free of criminal activities.

Gambling Commission

United Kingdom Gambling Commission

Year established: 2007
Licensed operators: 450+
The United Kingdom Gambling Commission (UKGC) oversees the activities of all entities operating in the UK. It is famously the strictest gambling commission globally, which means that online casinos with a UKGC-license are some of the securest you’ll find.

Curaçao eGaming

Curaçao eGaming

Year established: 1996
Licensed operators: 450+
When you see a casino licensed by Curaçao eGaming, you know that it has been given a seal of approval by one of the longest-standing commissions in the world. Its commitment to anti-fraud makes it one of most reputable names in the industry.


When it comes to online casinos, nothing will ever be as important as the security of a site. That should be any player’s first priority, even over the flashy games and bonuses. An online casino may have a track record of being trustworthy, but blind trust is never a good thing, especially when disclosing your personal and banking information. Learn what the safety signs are so that you can look out for them.

Having a legal and reputable license to operate is generally an indication of safety, but that’s only the starting point. We have a checklist that we go through before we can fully acknowledge that a casino excels at security. Only then do we feel comfortable recommending it to you as a top casino site.


Any casino site that takes itself seriously, will take security seriously. They know it’s not just a trophy to display on their site. It’s an ethos. Any best online casino in our list can’t ‘just’ be secure – it needs to be secure in everything it does. The below is our guide to evaluating whether that’s the case for any casino we review:

How to Determine if a Casino is Secure

  • Licensed by a reputable gambling authority
  • Payment methods utilize latest encryption technology
  • Games tested by an independent agency for RNG verification
  • The site is protected with SSL, TSL and https and similar measures
  • The operator’s track record is favorable regarding its other brands
  • Terms & Conditions that clearly state that the player is protected in various scenarios
  • 24/7 Customer Support that can be reached several ways
  • Not licensed, or licensed by a shady commission
  • No indication of your payment information being encrypted
  • No indication that the games have been independently-tested
  • No clear indication that the site takes protective measures
  • Negative reviews of brands owned by the same operator
  • Terms & Conditions that are vague or indicate that the player would not be protected in key scenarios
  • Limited contact details; lack of assurance that help is always available

Game Selection

Most people will tell you that the best online casinos should have hundreds of online slots of all kinds and varieties. This is mostly true. When a casino has a massive lobby, you can join it knowing that you’ll never run out of games to play. It’s also a guarantee that you’ll find games that you like, no matter what kind of player you are. However, there’s an even more important question we ask when evaluating a site for our best online casino list: what is the actual quality of the games offered?

Take slots, for example. There are thousands of online slots, and many of them are pretty bad. If we see subpar slot games at a casino, it does nothing to boost the experience of the site. That’s why our best online casinos only offer the crème de la crème of online slots. That means having a solid mix of modern, classic and jackpot slots, made by leading software providers. Naturally, the same goes for table games and live dealer games. Even if a casino has one kind of game as its main focus, we expect to see consistent quality throughout its lobby.


Live Dealer

Playing at the best live dealer sites means having moments where you forget that you’re not actually playing at a brick-and-mortar casino.



Most online casinos are brimming with hundreds of real money slots. Quantity is a valid consideration to have when picking sites, but the quality of the slots available is way more important.


Video Poker

The best video poker sites take the game you love and make it more dynamic – and despite being online, it’s still all about your skill and strategy.


Table Games

A massive range of roulette, blackjack, baccarat, craps, all with their own classic varieties and unique twists. That’s what you get at the best table games casinos.


When we review casinos, we really scrutinize the payment options available, because those determine how quickly and securely your money goes into and out of your account.

When it comes to payment options, there are two things a best online casino is bound to have. The first is a broad range of banking methods available to players. These include credit cards, eWallets like Paypal, bank transfer options, prepaid cards, and sometimes even cryptocurrency options. What you’ll also find at most top casinos are payment options included for the comfort of players in different areas. Visa and Mastercard are the most convenient options for American players, while players from other parts of the world rank eWallets in their top choices.

Other things we look out for in the best casino sites include low transaction fees and the convenience of being able to withdraw using the same deposit method used.

Above all else, the best online casinos will have withdrawals that are both speedy and secure. Deposits at most casinos you check out will generally be instant – no surprises there. That’s never the case with withdrawals. Before we recommend a casino, we ensure it has the proper encryption methods in place to protect your data while also processing your payout in a reasonable timeframe.

Promotions, Bonuses and Freebies


No Deposit Bonuses

No deposit bonuses generally mean free spins, but they can also take the form of live dealer tickets and similar tokens.

Not every casino will have a no deposit bonus for Newly Registered players, and that’s just fine – but they’re a great way of testing out a casino without playing any real cash.

What to Look out for

  • Low wagering requirements
  • A reasonable expiry-date
  • No option to opt out of the bonus if desired
  • Inability to cash winnings made from bonus

Welcome Bonuses

Odds are that the welcome bonus will be the first thing you’ll see on a casino site. We like a massive bonus like anyone else, but it’s important to not stop at the size of its match percentage. We check the underlying T&Cs to make sure players can genuinely enjoy it to the max.

What to Look out for

  • Reasonable wagering requirements (30x-40x is the average amount)
  • Your favorite games contributing towards the wagering requirements
  • A max cap on the winnings you can withdraw
  • Unfair maximum betting restrictions

Free Spins

Free spins can be given as part of a welcome bonus, but they can also be given out in dedicated weekly promotions. What we like to see is the chance to claim a relatively high number of free spins for a low deposit.

What to Look out for

  • A fair amount of free spins for your deposit
  • The chance to sample different games
  • High wagering requirements
  • Too quick of an expiration time
