Best Online Casinos

The next list of TOP 10 casinos is only a small part of a huge directory at Casinosexplorer.com because it is centred on the best casino sites in the world of online gaming, all with a five-star rating. Badge Overall, those are the most reputable and trusted brands with highest ratings, but to get full insight into their offers and more detailed information about specific online casino we recommend to check our reviews section.

Don't forget that many of these gambling sites are public companies with share stock market listings, therefore, there is no place for them and their financials to hide – their cards are de facto on the table.

* Instead of using the date when gaming company was founded stated values are calculated based on the year when the casino was launched online.

TOP by country

Here at Casinosexplorer.com we have done a lot of research to get accurate data regarding country restrictions for all casinos included in our top listings. As you have probably noticed, we have already published four flags that represent the countries from where are coming the largest part of our visitors.
Of course, we have done the same job for all other countries and based on your IP address on the next page you will find the list of best online casinos that accepts players from United States.

There is always a chance that you are protecting privacy or bypassing ISP blocking by using some VPN service, so the listed location info isn't correct. In that case, you can just select the brand you like and open its review page, and in the top right corner inside of it there is a link to the text file with the full list of prohibited jurisdictions for that casino.

Also, you can read the rules or pick some playing tips for a majority of casino games, including slot machines. For some players, online table games without croupier aren't the same so live section will show them top online casinos for real-time action with human dealers.

Offline vs Online casinos

Online vs Offline It's fair to say that a land-based room has its own irresistible attraction. There's something about the flamboyance, the flashing lights, the free-flowing drinks and often exclusive surroundings. However, not everything is positive, particularly the odds. Playing online is slightly more civilised, relaxed in the comfort of your own home, never subject to angry or possibly drunk players, able to hear yourself think and therefore allowing you to concentrate on your strategy. But the key differences comes from basic economic forces and games selection. The sheer volume of online gambling websites mean that competition is fierce and to attract new gamblers like you and hold on to them, these companies need to provide a professional customer service, tight player security and privacy, daily promotions, number of secure payment options, and ultimately damn fine odds. Otherwise, why return? And just take a look at the total count of games that offers one of top casinos listed on our homepage. It's over seventeen hundred and such a large choice you won't have in any land-based outfit, even in Las Vegas one. Also, with smaller house edge players can expect to win more money as payout percentage is better. In addition, sign up promotions and similar rewards offered can be viewed as an extra stream of revenue.

The fact is that virtual casino world is great and it beats offline in many aspects, so the next list contain the most important advantages of playing in the casino online.


  • The selection of games in an average online casino is much larger than in the land-based one.
  • Due to the lower operating costs, online casinos have a smaller house edge built in the games thus the better odds and the higher average payout.
  • No travelling costs.
  • Daily slots tournaments.
  • You have the option to split the screen into two or more windows and play multiple games at the same time.
  • Sign-up bonuses, free spins and loyalty rewards are not offered in the offline casinos.
  • Progressive jackpots are bigger because multiple online casinos can be part of the same network.
Casinos Explorer brings you jackpots for progressive slots which are offered by best internet casinos that operate on Netent, Microgaming, Playtech and other platforms.

How To Spot The Best Online Casino Sites?

Checklist Venture on to the web and type “Online Casinos” into any search engine and you'll find that there are plenty of casinos online looking for your business. This means more choice for the player. You can afford to be picky and play only at the top online casinos in the industry.

But how do you know which of them are really the best online casino sites? Well, we're here to help you navigate your way through the seemingly endless list of secure and safe casino gambling sites. In the next list, I'm going to discuss some of the most important points to look for when evaluating an online casino to help you separate the best from the rest. When you can identify these points you are ready to start playing at online casinos for real money.

We are putting this one first because lately, we're seeing more casinos limiting their playing area. There are still plenty of good casinos available for most markets, including the United States, Canada, United Kingdom and much of Europe. Check the casino's information page to be sure they accept players from where you live.

If you don't find the information listed there, look at the drop down box for countries on the signup form. If they don't list your country, you'll apparently need to pick another online casino.

There are a number of reliable services out there who certify casinos and a number of gaming jurisdictions who regulate them. Many casino sites will proudly display this information at the bottom of their homepage to let you know that they are a casino you can trust.

Regarding licensing, the information about the currently valid license is typically placed on the bottom/footer of the casino's website. For example, for players that live in the UK, an online casino must be licensed by the UK Gambling Commission. In addition, if they provide real money gambling on other territories besides the UK, they must have a license from Malta, Curacao or other licensing authority.

Look for seals from eCOGRA, TST (Technical Systems Tested), CFG (Certified Fair Gaming) and CDS (Central Disputes System). Keep in mind that no casino will feature all of these companies and regulatory bodies because they do overlap in the services they provide. But you should be able to determine where a casino is licensed and what reputable 3rd party certificators have evaluated it for fair play.

There are some big names amongst game developers such as NetEnt, IGT, Microgaming, Play'n Go and Playtech - to name some of the top players.

Now, these providers are invested in protecting their name which means they only want to license their software to the best online casinos. This makes life easier for players because if the casino is providing slots from the top developers in the industry, they should be one of the best places to play.

The top ranking online casinos are going to offer round-the-clock support. You should see information on the casino's homepage that mentions 24/7 support. If that isn't placed directly on the homepage, there should be a support link that takes you to a page outlining their service.

In addition to 24/7 support, look for toll-free phone numbers from your area as well as live chat and email options. A good online casino makes it easy for players to reach them.

Bonuses are often the heart of the online casino business. Bonuses are the way a casino keeps you playing with them, but often casinos restrict which games are good for clearing bonuses. Or they may impose playthrough or other wagering requirements that you need to consider. If you are the type of player who enjoys using welcome bonus offers, then check out the casino's offerings in advance and choose the ones with fair terms.

Not all online casinos have generous welcome packages, but several of our favourite casino sites listed above offer more to new customers. They will give a specified amount of free spins to new players that deposit required minimum. The minimum deposit amount is always stated in bonus terms and conditions. Currently, some of the online casinos from our list offer up to 300 free spins so make sure to check them. Spins are usually available for the new slot release or premium slots.

Please note that some of the welcome bonuses listed on our homepage are exclusive and only for our visitors so make sure to take advantage of such bonus. Of course, terms and conditions apply to all of them. This includes wagering requirements, game contribution, minimum deposit and time period (number of days to complete wagering requirements).

What about reload bonuses? We all know that every casino will reward a new player with a welcome bonus, but what to expect after 1st deposit. Well, when we rate a casino we look for daily, weekly and monthly bonuses. Many casinos are limited only on the single bonus and their ongoing promotions are rare or in state of nonexistence. In this case, we will penalise their ratings and put them on our toplist only when other features are exceptional.

This falls into the last but not least category of qualifications for the best online casino. Of course, you want to play at the casino that offers the games you like to play. The good news is that the top online casinos offer the broadest range of games. But if you need exact numbers just check out information here on top of our homepage.

The second important detail to pay attention is the number of games in the mobile casino. Some online casinos still have a huge gap when comparing desktop and mobile portfolio.

If you prefer to play on the live dealer tables than make sure to check does games selection at selected online casino covers your table favourites. If live roulette is your favorite than you can choose any casino, just as in the case of Blackjack. But if you prefer Caribbean Stud Poker or Punto Banco it is recommended to analyse our page with live casinos where you can compare their game selection. The best casinos will not only offer classic games but also novelties such as Wheel Of Fortune, Side Bets and Virtual Football.

It is important that the casino follow best practices with their customer information. One of the scariest aspects of online gambling can be to open an account at an online casino that doesn't take the necessary steps to protect your personal data.

We won't recommend a casino unless we are certain that their software is virus free. In addition, we don't want you to signup for an account anywhere where exist the possibility that they will sell or leak your information.

Depositing and withdrawing must be fast, easy and secure. To accomplish that task online casinos use the best payment methods available such as credit cards, e-wallets, prepaid vouchers, mobile invoicing and bank wire transactions. In fact, gambling operators are known as the ones that will embrace new technologies much before other industries. In this example, some online casinos were first to implement deposits via Bitcoin, today a well-known cryptocurrency.

On our page dedicated to depositing methods, you can check all existing options and find out what casinos accept the one you are looking to use.

Many players don't realize that online casinos often offer better odds than regular casinos at games like slots and Video Poker. The good news is that we are checking average payout percentages for every casino as a standard thing when writing reviews.

There are a few online casinos, Videoslots for example, that publicly disclose payout percentage for every slot game.

If you are a high roller player, then make sure to check the VIP page of the online casino you are interested in. Generally, all online casinos provide some sort of scheme to reward loyal players, but as always there are few exemptions.

Typically, the players will earn loyalty points that can later be exchanged for exclusive bonuses, free spins, trips, cashback and other prizes. Our experts have found that 888casino has one of the most interesting and rewarding VIP clubs so it is worth to check it.
