How We Rank The Best Casinos To Play Online Slots

Nowadays, it's harder to find an online casino with no slot games in its library than one with hundreds of such titles. However, not every operator offers the same quality of service, and unfortunately, some use unfair practices. Below, you can find the most important ranking criteria for finding the best best slots sites:

Licensing And Regulation

The only way to stay safe and secure online is by using the services of legit operators. The first thing to check is the license and its validity, which are usually displayed in the website's footer. Safe casinos usually have the best slots to play, verified by independent auditors. The main online gambling authorities are the UK Gambling Commission, the MGA, Curacao eGaming, and the Government of Gibraltar.

Game Selection

The best slots sites offer hundreds and thousands of games from different genres and categories. You can enjoy the finest RNG roulette and blackjack variations, as well as live dealer tables, lotteries, scratch cards, and many others. The best online slot games are always the most numerous category and are divided according to their themes, bonus features, RTPs, and other criteria.

Payment Methods

If you play the best online slot games to win real money and you succeed, you'll want to withdraw the cash! Players have different preferences, and the good operators offer all the payment options under one roof. When ranking the best slots sites, we check for enough credit cards, e-wallets, online banking and mobile cash apps, and crypto methods.

Payout Speed

The payout speed is also crucial for our experts, as it is for online gamblers. We always rank better platforms on which you can ash out your winnings quickly and conveniently. The processing time can be anywhere from 15 minutes to 48 hours and beyond. Always make sure that the casino operator is as dedicated as it should be!

Promotions And Bonuses

The best online slots for real money are even more fun with a proper bonus or package with free spins. Bonuses must be attractive but also fair, and we look at the T&C when evaluating this aspect of a platform. The low wagering requirements, full contribution, and reasonable validity guarantee fun and good chances of winning extra cash.

Mobile Compatibility

Mobile gambling is more popular than ever, and actually, in recent years, most of the casino bets are made on the go. Therefore, the best online slots sites must be compatible with Android and iOS devices and must provide mobile and browser-friendly content. Many also offer native apps for free download.

Customer Support

Last but not least, experienced iGaming operators know that reliable and friendly customer support is the key to success. The CS agents should be available 24/7 and proficient in their knowledge about the platforms and gambling matters, like the best online casino slots, for example. The range of communication channels also helps - live chat, phone line, email, contact form, social media, etc.

Types Of Games At Top Online Slots Sites

The top operators offer many gambling categories, including online casino slot games, table classics, and live tables. The best online slots are easy to recognize by experienced players or those who know what they are looking for. However, newbies may encounter difficulties with the terminology, however common it is. Therefore, we displayed the main types of games online:

Classic Slots

You'll find many classic machines among the best online slots, and the easiest way to recognize them is by counting the reels. The true retro slots have 3 reels and 5 fixed paylines in most cases. They are digital copies of the classic slot cabinets and often share the same interface. Classic slots are known to be simple and pay generous prizes. They feature fruit symbols, BARs, bells, sevens, and other classic symbols.

Video Slots

Video slots appear in different shapes and forms and are much more complicated than classic fruit machines. They can have 5, 6, or more reels and offer from 5 to 1 million ways to win. The modern video slots feature innovative mechanics, like Megaways, Cluster Pays, and Pay Anywhere. They cover a plethora of themes and scenarios, something for every taste.

Although some classic machines are also linked to progressive jackpot networks, most players look for bonus features in video slots. They could be as simple as wild and scatter symbols or free spins, reel modifiers, multipliers, and bonus minigames. The best slot games are loaded with Free Spins, Pick Objects, Hold & Spin, and Trail Bonus.

Card Games

Besides the best slots to play for real money, you will find various RNG card games online. Every ambitious operator has in its library blackjack and poker variations controlled by verified algorithms. The Random Number Generator guarantees fair results and payouts. Other online games with cards are baccarat, Dragon Tiger, Sic Bo, Andar Bahar, Teen Patti, and Bragg.

Roulette Games

If you prefer to spin than arranging card combinations and the top slots are not enough, check out the online roulettes. Almost every legit operator has single-zero (European) and double-zero (American) games in its repertoire. Some offer more sophisticated versions, like French Roulette, Auto Roulette, Two Ball Roulette, and many others.

Live Casino Games

Once you try live dealer games, the best slots online will never be enough for you! We should thank Evolution Gaming for this ultimate experience, though other companies have developed and built on his work. The live games are streamed from professionally equipped studios and run by experienced dealers or hosts.

The Live Casino games cover all gambling genres - blackjack, baccarat, roulette, craps, etc. They mix classic rules with modern features and add bonuses to upgrade the experience. Moreover, some of the best slots, like Gonzo’s Quest, are part of entertaining Live Shows.

How We Rank The Best Slot Games

We use a unique SlotRank metric to determine the best slots to play. The process is long and complex, and you see the final results only. We do not evaluate only the top slots but all titles across all gambling platforms. The SlotRank methodology remains the same for all regions, but naturally, the best slot games vary!

In order to determine the SlotRank of each title, we check its position in every online casino's lobby. The scan process includes all platforms generating enough traffic to ensure good exposure to the games. We always crawl the websites in Incognito mode to avoid personalizations. Our experts repeat the procedure for every market due to unique specifications and different brand weight.

The evaluation system is based on the average score that games will receive, and the best slots online usually have lower scores. The higher a title is in the casino lobby, the more points it gets. That score will be increased with a weight multiplier. It's as high as the size and popularity of local platforms.

Online slots that are unavailable in the lobbies get the highest score of 151. Therefore, the less points you have, the better the exposure is! The best slots to play online in every country have SlotRanks #1, #2, etc. The iGaming providers often release new games, and we include them in our ranking as soon as possible.

Each casino site is evaluated daily to note changes and include new additions. We use SlotRank to award the best slot games twice a year via SlotCatalog Awards. Providers responsible for their release get the appreciation they deserve for making waves in the iGaming industry.
