Our Verdict (9.5/10)

FanDuel was already one of the leading Daily Fantasy Sports operators before it launched its standalone online casino in 2021. Starting in New Jersey, it later expanded into other states with regulated real money gaming online. While it is called Mohegan Sun Casino in Connecticut, the site uses the same FanDuel platform found in states like New Jersey and Pennsylvania.

As a result, players can easily access the site and enjoy a variety of online casino slots. FanDuel has quite a few exclusive creations that share a progressive jackpot, awarded daily. This prize can exceed $25,000 and players can win it from any of the 50+ Daily Jackpots slots on the site. Around 500 other options are available as well.

The casino ensures safe transactions through multiple payment methods, including Visa, Mastercard, PayPal, Venmo, Apple Pay, Play+, PayNearMe, and online banking. The limits are more than reasonable as FanDuel is one of the best $10 deposit casinos, but it also caters to high rollers.

After making a first deposit, new players benefit from a money-back guarantee on the first 24 hours, up to $1,000. If you lose, you receive the cash back to try again. Other appealing slots promotions at FanDuel include weekly sweepstakes drawings with large prizes, daily spins of the Reward Machine for extra bonuses, and referral bonuses, all of which only have a 1x wagering requirement.

Caesars is easily one of the most popular casino brands in the world. The main company, Caesars Entertainment was founded in 1996 and continues to have its headquarters in Reno, Nevada. It owns more than 50 properties across multiple casino brands, including Harrah’s, Tropicana, and Horseshoe.

In 2021, Caesars Entertainment acquired William Hill, a renowned betting brand, in order to expand online in the US.

The company also owns the World Series of Poker and can redirect players to the online poker room with ease.

Despite the different Caesars Casino brands available online, the main platform remains the same. There can be some variations from state to state, but players can generally expect to find more than 500 online slots, along with various other games. It features titles from NetEnt, Scientific Games, Yggdrasil, IGT, Slingo, and other licensed developers.

Barstool Sportsbook & Casino has grown to become a popular brand for online betting and is now available in four states. The interface has a unique design that can take a bit to get used to. Users can find the casino section from the menu on the left and then browse more than 300 games on the site.

7. Bet365 – Handpicked Online Slots from the Best Developers in the US

Casino facts:

• Website: bet365.com
• Payout time: 0-24 hours
• Established: 2000
• License: New Jersey Division of Gaming Enforcement
• Headquarters: UK
• Available states: New Jersey

Our Verdict (8.6/10)

Bet365 is one of the top online betting brands in Europe and it is growing in popularity in the US as well. Although it is only available in New Jersey at this time, the gaming site stands out as one of the top online slots casinos. It is fully licensed and regulated by the Division of Gaming Enforcement in the Garden State and ensures a safe gaming platform.

During the Bet365 New Jersey review, we found premium games from top developers, like Playtech, IGT, and NetEnt. It also has its own Bet365 Games creations for extra options. The site is as simple as they come, with only a few styling touches. The good news is that the games are presented well, with large images and extra information regarding the reels, lines, RTP, volatility, and slots features.

The extra details make it easy to compare multiple slots and pick the preferred ones. There is also a category for bonus slots in the lobby, highlighting games with bonus rounds that can result in large wins. As for the jackpots category, this is quite slim and only has a few gaming options at this time.

The online casino offers a 100% welcome bonus that is great for playing slots, although the 20x wagering requirement is quite high. The 50% weekend reload bonus can be more beneficial as it only has a wagering rate of 10x for the total sum. Additional bonuses are available through the “Everyone’s a Winner” campaign that grants rewards for playing.

• Payout time: 0-24 hours
• Established: 2003
• License: New Jersey Division of Gaming Enforcement, Pennsylvania Gaming Control Board
• Headquarters: New Jersey, USA

Our Verdict (8.6/10)

Operated by BetMGM, Borgata Online Casino comes with an impressive library of slots and various other games. It also has the backing of a trusted operator and guarantees safe and secure banking through convenient payment methods. The site is now live in New Jersey and in Pennsylvania, which makes it a bit less popular than some of the other casinos covered above.

The good news is that it has loads of thrilling games and the bonuses to match. A major highlight is the collection of over 2,100 slots that cover classics, jackpots, bonus games, and the latest releases from Microgaming, NetEnt, IGT, Novomatic, Red Tiger, High5, Play’n GO, and other studios.

The online casino hosts exclusive jackpot drops known as Borgata Bucks. These are special events where players just have to bet on the featured slots to be eligible for random jackpots. Some of the events have a shared jackpot pool, meaning that one player wins half of the jackpot, and the other half is shared by all eligible players.

As one of the best New Jersey online casinos, Borgata offers generous bonuses, especially for new players. There is a $20 no deposit bonus for signing up and a 100% match on the first deposit.

• Established: 2006
• License: New Jersey Division of Gaming Enforcement, Pennsylvania Gaming Control Board
• Headquarters: Malta
• Available states: New Jersey, Pennsylvania

Our Verdict (8.4/10)

With a large following in Europe, Betway already had loads of experience when it launched in New Jersey in August, 2021. It also didn’t waste any time expanding in Pennsylvania that same year and is now looking at other states with legal online slots sites.

The platform comes with a mobile-friendly design and a collection of titles from multiple developers. In total, we found more than 400 slots, along with various other games on the site. The lobby makes it easy to browse and play the games on desktop computers and mobile devices. You can expect fast loading on iPhone and Android smartphones.

The online casino is a bit lacking when it comes to bonuses and promotions. However, you can claim a 100% welcome bonus on the first deposit and then access a calendar of offers after signing in on the site. We recommend checking the wagering requirement in advance as the rate can go up to 30x, which is higher than what some of the other top online slots sites require for their bonuses.

• Payout time: 2-3 days
• Established: 2020
• License: Michigan Gaming Control Board, New Jersey Division of Gaming Enforcement
• Headquarters: Nevada, USA
• Available states: Michigan, New Jersey

Our Verdict (8.3/10)

Although lower in our ranking, WynnBet is definitely one of the best online slots sites in the US. First of all, the Wynn Resorts brand is popular with casino players in the US and also in Macau. As a result, the online gaming site is safe, secure, reliable, and operates with licenses in New Jersey and Michigan. We also expect WynnBet to launch in other states soon.

As for the gaming site, the theme looks dated and the color scheme can use some work. The good news however is that the casino has more than 1,000 slots and it will take a while to browse the full list. There are some extra categories in the lobby for WynnBet exclusives, slots with Rapid Rewards bonuses, Mega Jackpots, Mega Drops, high-limit slots, and more.

You can even browse by developer from the lobby, with IGT, NetEnt, Konami, High5, Big Time Gaming, and Ainsworth being quite popular among slots players.

Moreover, WynnBet Casino has a 100% welcome bonus, reload bonuses, game of the week promotions, and a dedicated rewards program. Players collect FREECREDIT when betting on the games and can then go to the Rewards Store to redeem casino bonuses for free.

Comparison of the Best Online Slots Casinos

To sum up the reviews and to make it easier for you to find the perfect site, we present the following comparison table. Check out which online slots sites have the best bonuses, what platforms host the most games, and where you can find the most progressive jackpots.

Are Online Slots Legal in the US?

Yes, online casinos are legal in multiple states and slots remain the most popular gaming options.

The legal aspect regarding online casino gaming in the US changed a lot over the past decade. In 2011, the Department of Justice changed the interpretation of the Wire Act from 1961. This no longer banned all forms of gambling online on a federal level throughout the United States. As a result, individual states could legalize and regulate different forms of gaming over the internet.

Players can now access multiple slots sites in New Jersey, Pennsylvania, Michigan, West Virginia, Connecticut, and Delaware. More states are looking into passing their own regulations that would allow them to license operators for real money online slots within their borders.

How to Sign Up and Play Online Casino Slots

In order to start playing slots online, you simply have to sign up and make a deposit. We will go through the steps required to start spinning the reels right away.

1. Go to the site of any of the recommended casinos. We will use BetMGM.
2. Once on the homepage, look for the “Register” button and click it once.

3. You will need to enter some personal details in the registration form in order to create your own secure casino account.

4. Some verifications are needed in order to comply with online gambling regulations in the US. Verify your phone number and upload a photo ID to secure the account.

5. Make a deposit on the site by clicking on the “Deposit” tab at the top, selecting a payment method, and entering the details. You will also benefit from a 100% welcome bonus on the first deposit.

6. Open the casino section, select the slots category and browse the many options available. To start a game, simply click it once.

7. Set the size of the bet from the buttons at the bottom. These can depend on the game, but you can generally choose from a wide range of stakes.
8. Spin the reels by pressing the large spin button. You will automatically receive a payout if you land a winning combination of matching symbols.

How do Online Slots Work?

Slots are casino games that can come in many styles and cover a wide range of themes. At the core however, most slots follow similar mechanics. The standard game will have five columns, known as reels, and three visible rows of symbols.

After placing a bet, the symbols fall in random positions on the screen. Payouts are awarded if matching symbols land on active paylines, on adjacent positions, and from the leftmost reel to the right. Some online slots will also pay from right to left or even in any position as long as the symbols are next to each other.

The size of the payout depends on how many symbols are in the winning combination and also on the rarity of the symbol. Some icons will pay more than others because they appear less frequently on the reels.

How to Win at Online Slots?

Winnings are awarded automatically when you get a matching combination on the screen. Keep in mind that the symbols must be on the same payline for them to form a combination. Some games can have just one line, while most slots have around 20-30 active lines. Other titles can have more than 10,000 lines due to an increased number of symbols.

There is no real strategy that can guarantee a win when playing slot machines. You just set the size of the bet and spin the reels. Some factors that can influence the size and the frequency of wins are the RTP and the volatility.

Understanding Online Slots RTP and Volatility

The return to player rate (RTP) is a theoretical payout percentage based on the game mechanics and paytable. This is usually around 90% but some of the best online casino slots can have an RTP of over 96%. In theory, a higher RTP means better results in the long run, but short-term outcomes can vary significantly in both ways.

The volatility refers to the way the payouts are allocated. A game with a high volatility rate will rely on large wins, but these take place on rare occasions. A lower volatility means that players will receive smaller wins more frequently. This can affect the playing style and may also influence the size of the bet for longer sessions. Higher volatility means that you will need to have more spins available to cover losing periods.

Some of the new online slots sites, such as Bet365, make it easy to view the RTP and the volatility of the slots in order to better choose the right option.

How to Play Free Online Slots

A great way to practice new slots and learn how to play is to try out the demo version. This basically allows you to play for free while using demo credits as a way to keep score of the results. You start with a large balance and can even try out various betting strategies in the process. Plus, if you run out, you can just refresh the game and start again.

Unfortunately, not all casinos offer free online slots. We recommend checking out DraftKings as the best site for free games in demo mode. Here, you don’t even have to register an account to start playing. Simply go to the site, find the game you want to play and click on the “Demo” button on the featured image. You can always switch to real money play when you feel ready.

Best Payment Methods for Real Money Slots

To play slots for real money, you first need to add funds to your account. You can do this through various banking methods, but the available options can depend on the site and on the state from where you are playing. In general, you can find these payment methods at online slots sites:

• Credit and Debit Cards: These remain popular options for online gaming and are available at all of the featured sites. Visa and Mastercard are two main operators in this segment, while some casinos also accept Discover and American Express.
• E-Wallets: PayPal, Skrill, and Apple Pay are now the most frequently used electronic wallets for casinos in the US. They require customers to create accounts and fund them through other methods, but transactions afterwards are secure and fast, with low fees. They also make for quick withdrawals online.
• Online Banking: Online banking is a secure way to add funds to an online gaming account directly from your bank account. It is preferred for larger amounts given the reduced fees and the high transaction limits. For withdrawals via online banking, players may have to wait 3-5 days for processing.
• Prepaid Cards: Most casino brands now have their own Play+ prepaid cards. Customers can sign up and request a card that they can then fund through other methods. The Play+ card is great for managing the bankroll since it allows users to set clear limits and make fast transactions to and from the casino.
• Cash: Paying in cash is an option that is available at many top online slots sites in regulated states. Players can simply go to the local partner of the online casino and make a deposit in cash that will instantly be available in the account balance. Withdrawing is also supported via cash.

Types of Bonuses at Online Slots Sites

When playing online, you can easily claim bonuses and benefit from promotions for extra funds and other perks. This gives online gaming an edge over land-based casinos, since there aren’t many establishments that will double your money as soon as you walk through the doors.

Moreover, online bonuses are often designed for playing slots as these are the games that will contribute 100% for the wagering requirement, with some exceptions. So, it is important to know what bonuses are available to you and how they work. We will cover the main types of bonuses here:

• Welcome Bonuses: Generally available on the first deposit, the welcome bonus provides a big incentive to join the casino. This is usually a 100% match of the deposited amount in bonus funds, or a 100% refund on losses from the first 24 hours of play.
• No Deposit Bonuses: While rare, no deposit bonuses can provide good value for casual players. Some sites will provide a no deposit bonus just for signing up, as is the case with BetMGM and Borgata. While the amount is only worth around $20, this allows players to try out a few slots for free.
• Bonus Spins: Promotions that award bonus spins on selected slots are quite popular online, especially when it comes to new releases from top developers. Users can take part in the campaign, meet the eligibility criteria, and claim the spins to play the featured slots for free.
• Loyalty Programs: A great way to earn rewards based on how much you play is through online casino loyalty programs. The details vary a bit, but the concept is often the same. You earn points for every real money bet you place and can then exchange the points for bonus credits to play games.

How to Play Mobile Slots

Online mobile slots keep the same mechanics and bonus features, while allowing you to spin the reels on mobile devices. Most modern games are compatible with iPhone and Android devices, loading directly from the browser.

The controls can change when switching from the desktop version to the mobile one in order to provide easier access. Most games have a large spin button on the right side when holding the phone in landscape view. This disappears when spinning the reels to better show the symbols and the resulting wins.

Some mobile slots also support portrait mode, with the spin button lower down, but this doesn’t always provide a great view of the symbols.

Furthermore, leading online slots casinos can have native apps for both iOS and Android operating systems. These are available for free download from the respective store and can be installed on the device within minutes. A mobile casino app can provide faster access to the slots, along with extra security features, such as logins via Face ID.

Best Online Slots Game Developers

When it comes to filtering down a large collection of games, going by developer can be very useful. Most providers have their own style that can be seen across multiple slots, even if the theme changes. So, if you like some options from one provider, we recommend checking out more from the same studio since you might find other appealing games. These are the top slots developers in the US:

NetEnt

NetEnt is a hugely popular game developer that is now available on most online slots sites. It is known for creating eye-catching options that come packed with themed bonus features. Moreover, NetEnt slots often have a high RTP, making them more profitable in the long run.

IGT

IGT became popular in land-based casinos throughout the US before it launched the online versions of its top creations. It is a player favorite, especially among those with a fondness for old-school machines, such as Cleopatra, Wolf Run, and Siberian Storm.

Play’n GO

Play’n GO is a relatively new software developer that was founded in 2005. However, it quickly became popular for its immersive online slots, many of which come with innovative features. Players can also find detailed themes with thrilling animations.

Digital Gaming Corporation

Known as DGS, this provider brings handpicked slots from Microgaming to US casinos. It powers games like Ariana, 9 Masks of Fire, Immortal Romance, and many other titles that are worth checking out for their visuals and rewarding mechanics.

Big Time Gaming

Big Time Gaming is the software developer behind the innovative Megaways feature, which allows slots to have symbols of different sizes on up to 117,649 ways to win. While the feature is licensed to other developers, BTG also uses it in its top slots, such as Bonanza.

• Practice for Free: Before betting real money, try playing free slots online. This way, you can learn the different bonus features and see if you really like the game. You can also start small and play penny slots without breaking the bank.

• Try Out New Games: There are loads of online slots worth checking out and so you should try out different options. We recommend starting with our top 10 slots recommendations and then browsing more on the casino to see what stands out.
• Check the RTP & Volatility: A good way to choose between more than 1,000 slots is to look for games with an RTP of over 95% and a volatility that matches your playstyle. If you are looking for large wins, also consider progressive jackpot slots.
• Set a Budget: Play responsibly by setting a budget and spending limits for every session. Slots are meant to be fun and so you shouldn’t bet money that you can’t afford to lose. Don’t go over the limits and simply stop playing when it’s no longer fun.
