It’s common for many users, whether they’re veteran gamblers or novices, to wonder: Can I use U.S. online slots with real money safely and legitimately on the internet? And: Are all the online slots for real money legal, and suitably secure and authenticated? The answer to all of these queries is a resounding, “Yes!”

We run all our online slots with real money reviews through a series of operator and slot tests that take into account a wide variety of criteria. These include security & licensing, payment options, deposit and withdrawal limits, and available games.

We wouldn’t recommend any online slots that pay real money unless we consider them trustworthy and reliable. Our independent experts are rigorous in their tests and only rate online slots for real money if we think they’re worth your time. That’s why we can guarantee that the top-rated operators and online slots with real money are secure and legitimate.

Editor’s Recommendation for online slots with real money

When looking for the best U.S. online slots with real money, it pays to find reliable recommendations, and even harder to find the slots with the best payouts. That’s where we come in! Our editor looks at multiple criteria to judge not just which U.S. online slots with real money are the best overall, but which software provider is leagues ahead of the competition. In this regard, our editor’s recommendation is NetEnt.

One thing we look at when judging U.S. online slots with real money is reputation. Is the game provider well-known? How long have they been established? Taking these things into account is easy with NetEnt (aka Net Entertainment) as they are one of the giants in the U.S. online slots with real money industry. Established over 20 years ago, NetEnt provides over 200 online slots that pay real money in countries such as the USA, UK, Malta, Sweden, Gibraltar, Poland, and Ukraine. If you play online slots and games for real money, you’ve almost certainly played something by NetEnt.

The History of Online Slots

Slot machines were first invented in the late 1890s, and featured the basic blueprint still found today in online slots: matching symbols to win prizes. Back then, the jackpot might be a whole dollar whereas nowadays it’s not uncommon to find online slots that spit out thousands of dollars.

Whereas original slot machine models relied on pulling a level to activate the reels, you’re now more likely to find button-operated machines in normal casinos. This was just the first step in revolutionising the mechanic behind slots, that itself stems from the first video slot being developed in 1972.

All of this is what led to the first online casino that accepted real money, Intercasino (who still exists today), offering a choice of games. These slots were developed by software providers who also still exist today: Microgaming and CryptoLogic.

Microgaming were also responsible for the very first progressive online slot, Cash Splash, which featured 3 reels and a single payline. You can still play it online today, but with the choice of more reels and paylines.

The mechanics of online slots progressed very quickly so that we’re now in the position of video slots, interactive lines, and huge jackpots. Mobile gaming has also allowed online slots to be integrated into more than just casino apps, too. So, don’t be surprised if you find a top software provider now has their slots and games available separate from an online casino.

Legendary Online Casino Games

Speaking of which, chances are that if you’ve even just dabbled in online slots and games for real money, or read a few online slots for real money reviews, you’ve seen some, if not all, of the following legendary games from various game companies:

Gonzo’s Quest

Created by NetEnt, Gonzo’s Quest is one of those U.S. online slots with real money you’re likely to find at just about every online casino. A feature that makes this slot both unique and popular is Avalanche: symbols cascade down from the top of the screen instead of being spun. All slots pay out at their own Return To Player (RTP) percentage, with Gonzo’s Quest sitting at a respectable 96%.

Mega Moolah

This is one of Microgaming’s most famous slots, as it features four progressive jackpots: Mini, Minor, Major and Mega. They all involve different monetary amounts that can be won randomly, which has resulted in quite a few gamblers across the globe becoming record-breaking millionaires. In terms of look and style, it has an African theme with 25 paylines, as well as plenty of typical features like free spins and bonus payouts.

Deal or No Deal

It’s very common to find online slots based on game shows and Deal or No Deal, from Gamesys, is one of the best. It takes the form of a 5-reel video slot with 20 paylines. There are also four different jackpots available to win with this game, including a very popular progressive jackpot.

Mermaid’s Fortune

Gamblers looking for something a little different from their online slots should give this U.S. online slot with real money from Evolution Gaming a spin. Largely credited as being the first live video slot, it features a live dealer dressed as a mermaid who spins a ‘wheel of fortune’, in order to offer special bonuses alongside the traditional reels and paylines.

What To Look For When Choosing Between Online Slots With Real Money

Fans of U.S. online slots with real money or readers of online slots for real money reviews may already have formed their own opinions of certain software providers and their games, so we’re here to talk about what particular things you should pay the most attention to.

If you’re like us, you’ll prefer playing online slots for real money to visiting a brick-and-mortar casino. There is, of course, the convenience of finding U.S. online slots with real money from the comfort of your own home, but did you know that the best software providers offer an RTP percentage of 95-98% for their online slots for real money? This is a solid RTP for U.S. online slots with real money providers.

Also, if you’re searching for online casino slot games for real money, and you like to play on the go, it’s worth checking to see if a slot can be correctly displayed on a mobile device. Believe it or not, some software providers don’t take this into account, and it can make a huge difference.

Online Slots FAQ

Whether you’re new to U.S. online slots with real money or a seasoned gambler, there are a few common questions to consider:

Is it safe to play online games?

Absolutely! All reputable software providers take online safety and security very seriously, which includes using independent accredited test facilities to certify their online slots for real money. These can include Gaming Laboratories International (for security inspections) and eCOGRA (for live casino testing and certification).

Do I have to use real money with online slots?

No! The best thing about many online casinos and game providers is that they offer a free-to-play option on many slots. This means you can try it out and see if you like it, as well as study the mechanics, before committing actual cash to the game.

What exactly is a progressive jackpot?

Simply put, this is when the jackpot increases over time, usually because it hasn’t been won. This type of jackpot can be found on many different types of slot, from a variety of software providers.

Which Online Casino would you recommend me to play at?

This is something that’s definitely down to personal taste, although it can depend on if you prefer a particular games company or type of slot. Not all online casinos provide games from all software companies, so we recommend shopping around until you find what you like.

Can I get a bonus for playing online slots?

Bonuses are a popular way for providers to maintain and grow a player base, and many software providers are linked with a wide variety of online casinos with decent offers. These include welcome bonuses, no deposit bonus, free spins, and VIP offers.

Casino Legitimacy

We touched on a few reasons how a software provider and online casino can get a good reputation, but there’s a lot more to it than being independently accredited. The best software providers also ensure their games are handled by online casinos certified by a company such as Verisign or Norton, with SSL technology, to protect personal information.

The licence is also incredibly important, as there are multiple gambling commissions but many of them only cover certain areas. For example, most states provide a gambling licence that only covers players from that state. Always double-check that an online casino’s licence is applicable for where you live.

Safe Gambling at online slots with real money

It might seem obvious that any games company responsible for U.S. online slots with real money and the subject of multiple online slots for real money reviews would be player-friendly, but it’s a fact that’s easy to overlook. The best online slots providers are linked with casinos with safe and secure banking, including online slots that offer paypal and similar banking options.

All the best online casinos and their software providers make sure to focus on responsible gambling, with many even going so far as to make this clear on their websites. They should also incorporate self-exclusion and player limits to help gamblers manage their betting. If you or someone you know has trouble with online gambling, there should always be easy and free help available to help you or your friend manage their gambling habit.


So if you’re looking to take a punt on the best online slots and games for real money, what are the most important things to keep in mind? We would strongly recommend checking any online slots for real money are hosted by a reputable company (such as William Hill). Believe it or not, there are online casinos that claim to provide online slots that pay real money from known software providers, but they’re actually fake.

One way to be sure is to check the RTP value – often, these are much lower than the same game on a better-known site. This point also leads to other crucial criteria: security. Check that online slots for real money are legal by making sure a casino is correctly regulated and incorporates SSL certification. Lastly, don’t be afraid to check online slots for real money reviews like ours to make sure you’re choosing the very best place to wager your money!
