It’s one thing to review a slot or poker game — but an entire online casino loaded with features, rules, payment options, and reward systems that all have to be weighed, measured, and balanced in a fair, rigorous review? Not that simple. What exactly makes an online casino a top platform? Which casinos are worth spending time and money on?

From safety security measures to the game library, many variables go into determining an online casino hotspot. Below is our quick look at not only the best casinos, but an overview of their most important attributes.

Now that we know which of the top 10 casinos to check out — but what exactly got them these high-ranking spots?

Regulated and Licensed

Without exception, every recommended casino from a review site needs to be a licensed company. Licensed casinos are far more trustworthy than their unlicensed counterparts, for many reasons.

A licensed online casino is much less likely to try any funny business with you or your cash. One of the top problems that users complain about while using an online casino is paused or frozen funds or transactions for seemingly no good reason. Sometimes an honest mistake is afoot, but other times these unlicensed culprits are trying to stop you from getting your cash.

Among other reasons, licensed casinos are trustworthy because they’ve proven they follow the law of their own region. This helps build up a reputation among users and reviewers, and trustworthiness is important for businesses that want to last for decades.

Impressive Game Library and Diversity

For many users, the most important thing about any online casino is the games they have to offer. This makes sense — why else would anyone bother visiting an online casino in the first place if not to check out the software titles?

As a rule of thumb, the more games a casino has, the better. This applies to both the total amount of games (preferably in the hundreds or even over thousands) as well as the variety of the games. This usually includes slots, poker, baccarat, blackjack, and perhaps even some sports betting.

Keep in mind that many of the best online casinos out there don’t prioritize game type variety and still perform very well. This is because many gamblers are only interested in one type of game. More often than not, online casinos that focus on one game type focus on slots.

Still, the world of slots is big enough to offer its own sense of variety. There are video slots, 3D slots, progressive jackpot slots, more advanced slots that take inspiration from video games or esports, and branded, exclusive games that can’t be found at any other online casino.

Payment Options are Sound

Another very important element of online casinos is the payment options. This may not sound that significant to people who haven’t done much online gambling, but if you’ve ever won a big jackpot and wanted to continue riding that wave, you know how important it is to use an online casino with speedy payouts.

One of the main downsides of online gambling versus real-life casinos? Payouts are not instant. If you hit it big at a physical slot machine, you get to experience the thrill of being paid out right there in person. But with online slots, there is a wait period entirely dependent on which payment options you use.

Many online casinos already have instant deposits, so it’s the withdrawal methods that reviewers tend to look at — their speed can take several days, so ideally you want your payout in 24 hours, preferably no more than 48.

Payment option diversity is also important, too. You don’t just want to see major credit cards, but e-wallet services like PayPal, too. Cryptocurrencies like Bitcoin and Ethereum are always a plus thanks to their anonymous methods, although these aren’t as common.

Works Great on the Go (Mobile Functionality)

Online gambling offers a lot more convenience than doing it in person, and most of that convenience comes from being able to gamble on the go — at any place and at any time. An online casino needs to function just as well, if not better, via portable methods.

Many casinos will use a mobile version of their main site that is fitted for smartphone and tablet screens. Though this can be suitable, it’s usually ideal to register with an online casino that has a dedicated app instead.

Mobile casino apps are a fantastic way to do online gambling. The best ones regularly receive updates, have a great UI, and all of their games are fitted to look crisp and slick inside the application. Many industries would benefit from focusing more on mobile app usage, and online gambling is definitely one of them, much like esports or online retail.

Mobile apps are also less likely to have bugs or glitches compared to their mobile website counterparts, so their stability for longer sessions is in demand too. Though it’s not necessary for everyone, most fans of online casinos these days would rather use a mobile app, and it’s clear to see why.
