How Did We Pick The Top 100 Best Online Casinos

So, how do we choose the best casino online sites? How did we prepare the list of 100 best online casinos? We have a long list of criteria to use in our reviews: Every casino must take a passing grade on every criterion so that we can recommend it. We list our criteria below and provide you with more information about our selection process.

Bonus offers: We explained the details of this process in our casino bonus guide: We check the terms, conditions, and the wagering rates of bonuses, not the “numbers”. A welcome bonus that offers a 300% match rate sounds nice, but is it also fair? Does it have a reasonable wagering rate? We check each bonus offer and find out how it really works

Game variety: We check both the quality and quantity of game collection. We expect to see at least a thousand games in different categories and we would like to see the games of top-tier providers. We make sure that you can play the latest & most popular games. We also check for the free games feature: We believe that you should be able to try all the games in a casino for free first.

Mobile experience: Nowadays every online casino must have a mobile casino app. Players want to play on their mobile devices and the casino must be able to offer this option, via a native app or a website that is compatible with all mobile platforms. We use different kinds of devices (iOS & Android) in our mobile casino reviews and make sure all of them work without a problem.

Signup process: We believe that the registration process must be as simple as possible and completed as fast as possible. We especially recommend playing at online casinos with the instant registration feature and we check how easy & fast this process really is.

Payments: We have a guide about how to recover lost money in casino but hopefully, you will never need it. We make deposits and withdrawals personally and find out how reliable they are. We check the deposit fees, withdrawal times, approval periods, and make sure that this process is as easy as possible. We pick casinos for every budget, so you can play and have fun no matter what your bankroll is.

Unique features: Some online casinos offer really unique features, such as an interesting loyalty program or multiplayer races open to every member. Such features are always a plus: We like to see original features.

Security and license: We want you to play at a safe online casino, so we check every page for SSL encryption and validate the status of the electronic gaming license. We never recommend playing at unlicensed (rogue) casinos. You will be able to play safe, fair, and legal websites when you use our list of 100 best online casinos.

Customer support: The customer service represents the casino, so it should be professional, easy to reach, and helpful. We create scenarios and ask the support team to resolve them. We check how fast and professional they are.

Language & currency support: As a general rule, online casinos should support more than one language and currency – the more the better. Support for cryptocurrencies is a big plus.

Signing Up To One Of The 100 Best Online Casinos: A Simple Guide

Becoming a member of one of the top 100 best online casinos is not a hard job: You can complete the whole process in a maximum of 10 minutes. If this is your first time, here is what you need to do, step by step:

Step 1
Check the list of 100 best online casinos and pick one. Visit the website of that casino.
Step 2
Look for a button that says “join”, “register”, etc. on the main page. Click that button.
Step 3
Fill out the membership form. Make sure to give accurate information because you will be asked to verify it when you want to make a withdrawal.
Step 4
The casino will send you an email – click the link in that mail to activate your account.
Step 5
Return to the casino website and use the “login” button this time. Log in with your username & password.

That’s it: Check the current promotions page first because there may be a bonus waiting for you. Make your first deposit and start playing: Good luck!

Types Of The Top Online Casino Sites

The list of the top 100 best online casinos is unique: It contains different types of online casinos. Most people think that there is a single type of online casino – that’s wrong. It is possible to divide casino sites into five basic categories. These are:

  • Instant Play Casinos: The majority of modern online casinos fall into this category. Back in the day, you needed to download a program to reach the casino website and play games. Now, there is no need for it: All the games and services in a casino site can run on any browser. No download is needed – that’s why they are called instant play casinos. You click the “play” button and the game launches on your browser in mere seconds.
  • Download Casinos: Casinos that ask you to download a program still exist. Some players still do not have a fast internet connection and they need these programs to get stable gaming experience. Although they are few in number, download casinos are still out there. In such casinos, there is usually no live dealer service and the number of games is limited, usually not more than 200.
  • Mobile Casinos: Online casinos that can run on mobile devices without a problem. As explained above, all of the modern casino sites are also a mobile casino nowadays, so they are pretty common. Simply visit the website of any online casino with your mobile phone and you will be able to play all the games & use all the services.
  • Live Dealer Casinos: Casinos that broadcast live and offer the chance to play against a real dealer. The idea is simple: A croupier puts several webcams in front of the game table and starts a live broadcast. Anyone can join that broadcast from anywhere in the world and play in real time. You can also play with other players like you and interact with them. This is an exciting technology and it is a must nowadays: Every online casino must be able to offer live dealer games.
  • VR Casinos: VR casino sites represent the future of the iGaming industry. These are websites that can be accessed using special googles. They are like a 3D simulation: You can move inside the casino and play games with your hand movements, there is no need to use a keyboard & mouse. Although they are limited in numbers, VR casinos offer an amazing experience and we believe that one day they will become the industry standard.
  • No Account Casino Sites - temp

Here are our recommendations:

paysafe big logo
