The accessibility and convenience of online casinos has made them the favorite of countless punters. Moreover, their enormous game libraries, versatile bonuses, and numerous banking options make them the perfect starting point for anyone looking to partake in casino games. However, you ought to consider dozens of factors when choosing an online casino. Join us on this deep dive into online casino reviews and ratings to learn more.

Initial Attraction

While the eternal maxim of “do not judge a book by its cover” is great to keep in mind, most people fall for an attractive cover. We want you to approach an online casino as a detective and keep the following shiny yet empty allures in mind:

  • Fancy marketing stunts - Some online gaming venues invest more money into marketing than their product. This then leads to punters jumping into online casinos expecting the world and getting nothing but regret.
  • Elegant UI design - We greatly value elegant UI designs, but they should not be your only requirement. Moreover, a nice design can often give you the impression that an online casino is cutting-edge despite having a poor selection of games.
  • Very generous bonuses - The most common way that an online venue tricks punters into depositing is by waving a generous bonus in front of them. Make sure to consider the wagering requirements and eligible games before claiming any bonus.
  • The latest casino games - Having the latest casino games in your portfolio is wonderful unless it's the only thing that you offer. Make sure that your chosen venue boasts classics and the latest releases.
  • Enormous progressive jackpots - An enormous progressive jackpot is amazing bait. However, you need to ensure that the required wagers are sustainable and that you enjoy the underlying game.

What Matters in the Long Run?

When you push away the initial attraction that has you click on an online casino site or its ad, you need to start focusing on things that matter in the long run. The most important aspects of real money play, which we also cover in our expert reviews and rankings, include:

  • Game selection - An online gaming venue should offer a plethora of casino games that include slots, baccarat, poker, blackjack, roulette, craps, keno, bingo, and their countless variants. Moreover, you should have access to both niche titles and the latest releases.
  • Bonuses and promotions - You should expect the full array of online casino bonuses and promotions, including welcome, reload, cashback, free spin, no deposit, deposit, high roller, loyalty, and refer-a-friend bonuses.
  • Compatibility and accessibility - Expect to find solutions for mobile, desktop, and laptop gaming. Note that some online casinos deploy dedicated apps, while others simply optimize their website.
  • Software - Casino software is incredibly important since it is the ultimate line of defense between you and hackers. Moreover, poorly designed software can cause lag and interruptions when gaming.
  • Payment options - The best online casinos offer banking options that meet their customers halfway. Expect everything from traditional solutions such as credit cards, debit cards, prepaid cards, phone billing, and bank transfers to modern breakthroughs such as e-wallets, cryptocurrencies, and Google or Apple Pay.
  • Customer support - One of the most important aspects of an online casino is its ability to provide customer support. The latter should be available 24/7, in multiple languages, and via various channels.
  • Licenses - Never join online casinos that do not have clear licenses. Moreover, avoid casinos that throw caution to the wind by not following regulations or avoiding third-party audits.

We will explore all of these points and more in the upcoming sections. We recommend that you have a gander at all of them, explore the ones that interest you the most in-depth, and check out our FAQ question for any potential inquiries. We offer a dedicated Casino Comparison Tool to help you choose your next gaming venue.

Gaming Legislation

The bedrock of any trustworthy establishment is its ability to procure and maintain the best licenses around. The gambling legislation and its legality differ from country to country and occasionally between regions in the same state. This is especially true of confederate or union governments comprised of multiple autonomous states, such as the United States of America.

Licenses, Regulators, Audits, and Taxes

The actual licenses that your online casino operator has to obtain are based on your jurisdiction. However, some of the most respectable licenses the world over are issued by the Malta Gaming Authority (MA), the United Kingdom Gambling Commission (UKGC), the Gibraltar Gambling Commission, and the government of Curaçao, so rest assured that everything is fine if you see either. We recommend that you check out our licenses section to learn more on this topic.

More progressive jurisdictions do not stop at simple gambling legislation but also require gambling venues to have responsible gambling programs in place. Moreover, our industry experts expect to find audits from third-party agencies, which further reinforce the legitimacy of a gaming venue.

The most respectable gambling auditors the world over include eCOGRA (eCommerce Online Gambling Regulation and Assurance), iTechLabs, GLI (Gaming Laboratories International), and BMM Testlabs.

Things become a bit dicey when winnings are paid out, as every country and region has a slightly different policy. The UK, for example, does not tax lottery winnings, while most other countries do. While some transfer said tax directly to the state, others grant it to the local municipality. We recommend that you research your local laws or simply reach out to your chosen online casino to learn more.

Remember that some online casinos even feature Seals of Approval from reviewers such as us at OCR. Our Seal of Approval leads you directly to the related casino review, which covers the ins and outs of an online gaming venue and is a testament to its quality. Note that our Seal of Approval cannot be bought; it can only be earned. Check out our dedicated guide to learn more.

Casino Technology

When the very first online casino launched in 1994, nobody expected technology to advance this far. The first-ever casino games were even text-based and offered little excitement. As technology developed, so did the iGaming industry and its casinos. Modern online gaming venues are masterpieces of innovation that push the envelope across the board. When we rate and review online casinos, we expect them to encompass or at least touch the following technologies.

From HTML to PWA

The first online casinos were based on HTML and a bit of JavaScript. JavaScript eventually got several extensions and offshoots, HTML got a jumpstart with various frameworks, and CSS became more powerful and responsive than ever. Developers started using React, Angular, Node.js, Vue.js, Workbox, APIs, middleware, NoSQL databases, and a sea of other solutions. These allowed them to create responsive, compatible, and versatile cross-platform solutions that had unparallel accessibility and security.

Mobile Casinos

The desire to gamble on the move or from the comfort of your living room gave rise to mobile casinos. These brought the iGaming platform to smartphones and tablets running Android, iOS, and even Windows Mobile. Developers now feature mobile-specific titles, and operators offer mobile-specific bonuses. Check out our dedicated guide to learn more.

Live Casinos

Not everyone has the time or energy to travel to brick-and-mortar casinos. A phenomenal solution are live casinos, which allow you to take in the atmosphere of a real venue from the comfort of your home. You will see live streams of blackjack, roulette, baccarat, slots, craps, and more. All of these are led by professional dealers and croupiers whose handiwork is streamed directly from dedicated studios or actual casinos. Check out our dedicated guide to learn more.

Virtual Reality (VR) and Augmented Reality (AR) Casinos

Online casinos really want you to feel as if you are in an actual gaming venue, which is why they are now investing heavily in VR and AR support. Virtual reality teleports you directly into a replica casino with the help of a VR headset, while augmented reality displays a slot, table, or other casino device in your living room.

AI, Crypto, and More

The future of online casinos is in VR, AR, AI, and crypto. Artificial intelligence is particularly interesting because of its usage in chatbots and personalized game recommendations. Crypto, on the other hand, is phenomenal for anonymity and fast transfers. Check out our dedicated guides to learn more.

Casino Games

A casino has to offer numerous games in several categories for us to give it a high score. While quantity is important, we give more weight to quality. We will use this section to quickly dive into the various gaming genres, their titles, and developers.

The Most Popular Game Genres and Developers

The online gaming industry is packed with amazing casino games and developers who regularly go the extra mile to make gaming sessions unforgettable. The most popular casino game genres, their representative titles, and developers are:

  • Slots (slot machine games) - These one-armed bandits were immortalized by titles such as Mega Moolah, Starburst, Book of the Dead, Gonzo's Quest, Mega Fortune, and Cleopatra. These titles were developed by Microgaming, NETNETN, Play'n GO, and IGT, respectively.
  • Blackjack - The immortal game of 21 features games such as Classic Blackjack, Atlantic City Blackjack, European Blackjack, and Vegas Strip Blackjack. These were developed by Microgaming, NETENT, Play’n GO, Evolution Gaming, and Betsoft Gaming.
  • Roulette - Spinning the endless wheel of luck is unforgettable when playing European, American, and French roulette from developers such as Microgaming, NETENT, Playtech, Evolution Gaming, and Betsoft Gaming.
  • Video Poker - Experience a mixture of slots and poker in titles such as Jacks or Better, Deuces Wild, Aces and Faces, and Joker Poker from software providers the likes of Microgaming, NETNENT, Playtech, Play’n GO, and Betsoft Gaming.
  • Baccarat - Take in the unforgettable atmosphere of baccarat with Punto Banco, Baccarat Banque, and Chemin-de-Fer from developers such as Microgaming, NETNENT, Playtech, Evolution Gaming, and Betsoft Gaming.
  • Craps - This dice game is best experienced in titles such as Craps Live, Craps Master 3D, Craps HD, and Craps Dice Shooter from developers such as Microgaming, NETENT, Playtech, Evolution Gaming, and Betsoft Gaming.
  • Live Dealer Games - Play with real dealers in Live Roulette, Live Blackjack, Live Casino Hold ‘em, Live Dream Catcher, and more from Evolution Gaming, NETENT Live, Playtech Live, Ezugi, and Authentic Gaming.
  • Poker - Take on games such as Texas Hold 'em Poker, Carribean Stud Poker, Three Card Poker, and Casino Hold 'em from Microgaming, NETENT, Play'n GO, Evolution Gaming, and Betsoft Gaming.
  • Keno - Experience this Asian sensation with titles such as Keno Blast, Power Keno, and Classic Keno from Microgaming, NETENT, Playtech, Betsoft Gaming, and Pragmatic Play.
  • Bingo - Playing 75-ball, 80-ball, and 90-ball bingo, Bingo Billion, and Bingo Bonanza is unforgettable, especially when the game is developed by Microgaming, Playtech, NETNENT, NextGen Gaming, and Pragmatic Play.

Gaming Gems and Nuances

We cannot discuss online casino games without touching on live casino games and jackpot schemas. These allow punters to pursue unforgettable gaming experiences, which is why our in-house experts value them highly.

Live casino games allow you to interact with a human dealer and other punters in real-time. Moreover, they allow you to take in the atmosphere of a real gaming venue from the comfort of your home. Prime examples of live casino games include Live Roulette, Live Blackjack, Live Baccarat, and Live Poker. Some of the most notable variants include Casino Hold ‘em, Carribean Stud, Three Card Poker, and Texas Hold ‘em.

Being able to land an enormous jackpot by simply playing a fun casino game is a dream experience. We, therefore, expect to see progressive, fixed, local, and networked jackpots in the game portfolios of online casinos. Prime examples include Mega Moolah by Microgaming and Playtech’s Age of the Gods series.

Casino Bonuses and Promotions

Punters often jump at the prospect of claiming a large bonus or promotion. While using a bonus is intrinsic to countless gambling strategies, it is paramount that you know exactly what you are getting yourself into. Bonuses and promotions are vectored offers that target beginners, reloaders, high rollers, and VIPs, respectively.

Some of the most popular online casino bonuses, which you will often find highlighted in our ratings and reviews, include welcome bonuses, no deposit bonuses, free spin bonuses, reload bonuses, cashback bonuses, loyalty or VIP bonuses, match bonuses, and high roller bonuses. Some of these, such as welcome bonuses, often come in packages. Said packages require multiple deposits in order to be fully claimed, with the deposit matching percentage being between 50 and 150%. No deposit bonuses usually give you a small sum, such as 5 USD, and very stringent wagering requirements. High roller bonuses, on the other hand, give you enormous bonus funds in the thousands of Dollars, Pounds, or Euros.

However, the actual bonus amount can easily make you forget about wagering or playthrough requirements. When you combine these with eligible games and withdrawal limitations, you can get a recipe for disaster. It is, therefore, vital that you read the terms and conditions of your chosen bonus or promotion. Check out our dedicated guide to learn more.

Online Casino Rules and Guidelines

The rules and guidelines that an online casino features are mostly independently penned. While the local jurisdiction and its laws impact said rules and guidelines, casinos have a lot of freedoms. They can impose age or geographical restrictions, deposit and withdrawal limitations, account limitations, identity verification, custom bonus terms, gaming etiquette requirements towards players and staff, and even prohibit certain activities that could disrupt or ruin sessions.

The terms and conditions of any given gaming venue are, therefore, incredibly important to the quality and longevity of your gaming session. Breaking the rules and guidelines can result in account limitations or even suspension, so make sure to read them before joining an online casino. Note that our ranked and reviewed online casinos boast fair rules and guidelines that meet punters halfway. However, if you encounter a shady casino with shady rules, be sure to report it in our blacklist section.

Kicking Things Off

There are a few things that you should add to your checklist before you start your online gaming adventure. These vital online casino aspects include:

1 Security Measures

A great sign of a conscientious online casino is its dedication to the latest security solutions. Some casinos are even jumping on the blockchain in order to keep a transparent record of their operations.

2 Banking Options

We have often mentioned the importance of various payment options, but that is not the only requirement in terms of banking options. You should also be privy to fast payout processing and minimal fees.

3 Accessibility

You should have access to your chosen online casino from your favorite device, be it based on Windows, Android, macOS, or iOS. Moreover, the casino’s website and games should adjust to the proportions of your screen.

4 Bonus Terms and Conditions

Never claim a bonus without reading its terms and conditions first. These include mentions of wagering requirements and eligible games, which can make or break your gaming experience.

5 Customer Care

The responsiveness and readiness to help of your chosen venue's customer support are vital to your long-term gaming fun. We even recommend that you conduct a stress test during rush hour to see how well the customer support team performs.

6 Fair Play and RNGs

Fair play extends beyond offering a solid selection of games. It encompasses professional live croupiers that do not fiddle with cards and random number generators, whose results are determined by Lady Luck alone.

7 Licensing and Regulation

The main reason why you should expect the best licenses and regulatory oversight is that these regulatory bodies mediate disputes and help you enforce your rights. They are often the last line of defense when a casino is rogue.

8 User Experience

Punters often forget that the visuals of an online casino UI matter. If a user interface is filled with useless buttons and pesky texts, it can greatly hamper your gaming fun. What is more, if the UI is unintuitive, you can accidentally press the wrong button.

That depends entirely on your local laws and regulations. Note that the laws in your country might differ from jurisdiction to jurisdiction, so make sure to research this thoroughly.

Yes, there are plenty of mobile casinos. These usually come in the form of optimized browser applications. However, there are some venues that offer dedicated apps that you can download from Google Play, App Store, or the host site.

Yes, you can definitely win real money as long as you wager real money. Some lucky players even win enormous life-changing jackpots to the tune of millions of USD.
