1. InterTops - Best Overall Online Casino

Launched in 1996, InterTops was initially a sports betting site and was considered by many to be one of the best around. Following their initial success, InterTops chose to expand their platform to include online gaming, and since then, they have incorporated video poker, table games, and a handful of specialty games as well. However, where the site really shines is in its impressive array of online slots, including a collection of 54 games of 3-reel slots and 117 games of 5-reel slots.

For those interested in 7-reel slots, InterTops does currently offer two 7-reel games, one of which is a low-volatility, frequent payout offering, the other being a high-volatility affair with larger than average jackpots.

Anyone opening an account and looking to play for real money with InterTops must provide all the standard KYC information they would have to give any other real money online casino. While we are on the topic of accounts, it is important to note that although InterTops does accept US customers, residents of Washington State, New York, New Jersey, Louisiana, Kentucky, Maryland, and Missouri are not eligible to open an account.

InterTops has also become recognized for their online gaming tournaments, most of which are geared towards online poker and other table games, although progressive slots are also supported. These tournaments host players from all over the world and are open to gamers of every skill level. Aside from the tournament options and impressive selection of five and three-reel slots, InterTops also offers a generous 100% deposit bonus for first-time customers. Furthermore, the online casino offers several non-deposit bonuses as well.

When it comes to funding, InterTops offers a convenient list of options, including credit card, Neteller, Paysafecard, and even Bitcoin. All-in-all, InterTops is considered by many to be one of the best online casinos around, and for all the reasons covered above, it's easy to see why.

When it comes to live dealer games, Red Dog provides its users with access to a host of live games that are offered and maintained by Visionary iGaming, a leading provider of live dealer solutions online. Unlike many other gambling sites, Red Dog has developed various slot and specialty games in-house that users can enjoy along with some of the most popular casino games like WildFire 7s, Pay Dirt, Cash Bandits, and video poker, black jack, craps, and roulette.

The next, and newest, online casino on our list is SuperSlots. Although just over a year old, the site has already become noticed as offering one of the better selections of real money casino games available, and their extensive array of 5-reel slots is one of the first things users will notice while logging on.

Moreover, each game has a small preview box that appears when the mouse cursor is held over the top of a game's thumbnail. When this preview box appears, it provides a short description of the game and a measure of the game's volatility on a scale of one to three. This simple little feature makes it easy for users to pick the game that is right for them.

For those interested in games other than slots, SuperSlot offers six games of black jack, four video poker games, and two live gaming options. The main drawback to SuperSlots is that many users complain about poor functionality of the website.

That being said, where SuperSlots really shines is in their cryptocurrency options. While most online casinos have begun accepting Bitcoin, the transaction fees over the bitcoin network are quite high, making smaller denomination deposits costly. Besides Bitcoin and Ethereum, SuperSlots also accepts Litecoin, Bitcoin cash, USD Coin, and Ripple, all of which have much lower transaction fees (especially Litecoin and Ripple).

In conjunction with a large offering of progressive jackpots, the site also grants a 350% sign-up bonus up to $2,500 and a $1,000 daily giveaway.

As has become the standard, Cafe Casino also accepts bitcoin as a payment option. Like many other casinos online, it offers bonuses and incentives to those willing to use Cryptocurrency as their primary payment option.

Best Online Casino Sites FAQs

Now that we have outlined our top eight picks, it's worth taking a moment to look at some of the most common questions people have when talking about online casinos.

What is the best online casino?

As stated by our list of the top online casinos, InterTops can be considered the most well-rounded and overall best site as it allows users to play online casino games and bet on sporting events. RedDog and BigSpin are both quality options as well.

What is the difference between a real money casino game and free casino games?

As the name implies, real money casino games are games (slots, poker, black jack, etc.) where wagers are made with real money, either fiat currency or crypto. Free games are games where wagers are not made with real money, and thus no profit or loss can be incurred.

Should I fund my account with Cryptocurrency?

Cryptocurrency is an excellent way to fund your account because it is quick and easy once you get the hang of it. Furthermore, there are many extra online casino bonuses to be collected as most online casinos these days prefer their customers to make deposits using crypto instead of fiat.

That being said, the network fees associated with coins such as Ethereum and Bitcoin can be pretty high at times, making them impractical for depositing a small amount. To avoid fees, look for sites that support payments via Stellar Lumens, Ripple, Litecoin, and Doge.

Which online casino has the best payouts?

Payback percentage, sometimes referred to as RTP (the amount of each bet that is returned to the player), is set by the individual game and not the provider. In most cases, slots will have an RTP of anywhere between 85% and 98%, and other table games are similar.

The exception to this is sports betting. In this instance, the operator has some say in the odds and spreads available.
