Best online slot sites for 2025
Our team has reviewed the best online slot casinos in the country. We focused on the quality and variety of each collection, along with the bonuses, RTP percentage, user interface, payout speeds, and the customer support. Given this criteria, we have determined that these best online casinos for slots:
1. DraftKings Casino slots
DraftKings is the best online slots casino in our ratings right now. In some states, it offers more than 2,000 slots, including exclusives such as 2 Tribes, American Treasures, DraftKings Balloon, Just Kitten Around, and Loki’s Luck. The app also hosts leading games from major suppliers like NetEnt, High 5, and IGT, along with titles from smaller studios.
It also runs its own progressive jackpot network, covering most of the exclusive slots as well as various slots from external suppliers, including Cash Eruption, Cash Machine, Cleopatra, Da Vinci Diamonds, Fortune Coin, Gonzo’s Quest, Jumanji, and Starburst Xxxtreme. Some slots have a single progressive jackpot, which may reach seven figures. In that case, you’ll only need to bet $0.10 per spin to be in with a chance of winning it. Others have four jackpots (mega, major, minor, and mini), and you need to pay $0.25 per spin to participate.
The DraftKings Casino lobby does not have as many shortcuts, categories or filter options as rivals like BetMGM. It does, however, offer a powerful search option, and pages load quickly, so it is not too difficult to find a specific game. Another potential drawback is the lack of customer support options. Caesars Palace, BetMGM, and FanDuel offer stronger customer support.
However, DraftKings stands out by offering an attractive welcome bonus and lots of ongoing promos. It also provides broader deposit and withdrawal limits than rival slot sites.
2. FanDuel Casino slots
The FanDuel slots app offers the most user-friendly interface on the market. Navigation is simple, pages load quickly, and many useful sections and shortcuts exist. The homepage is quite busy, with vibrant animations that showcase specific slots.
You will find sections for featured games, new releases, daily jackpots, progressive jackpot slots, bonus buy slots, streaming slots, Megaways slots, casino floor favorites, and so on. There is also a section for the top 10 games in each state. FanDuel offers a more sophisticated platform than DraftKings, and it is optimized for mobile play, too. As such, FanDuel Casino has a higher average user rating than any of its key rivals on both Google Play and the App Store.
FanDuel does not offer as many exclusive slots as rivals like DraftKings and BetMGM, but it is working to address that issue. Recent releases include World of Wonka Pure Imagination, Cosmic Cash, and Gronk’s Touchdown Treasures, which were developed exclusively for FanDuel Casino.
While FanDuel cannot compete with BetMGM and DraftKings in terms of game variety, it has nevertheless built a diverse library, featuring some of the best games from a broad spectrum of providers, including Red Tiger, NetEnt, High 5, IGT, Lightning Box, and Light & Wonder. The selection continues to grow, too, so it is easy to see why FanDuel is now the market-leading online casino in some states.
3. BetMGM Casino slots
BetMGM offers the largest selection of online slots in the United States. Players in New Jersey can browse more than 4,800 slots, available from dozens of providers, and there are over 4,400 slots in Michigan. It has a slightly smaller library of slots in other states, which do not have as many licensed suppliers, but BetMGM excels in terms of game variety.
BetMGM Casino is co-owned by MGM Resorts International and a European company called Entain. The latter is one of the world’s leading online casino operators, with brands that include PartyCasino and bwin. Entain has provided BetMGM with an impressive user interface, replete with an array of exclusive slots.
BetMGM also has an internal progressive jackpot network that includes games like MGM Grand Millions and Bison Fury. It shares this network with sister sites such as the Borgata online casino in some states. These progressive jackpot games have delivered record payouts in certain states. You will also find progressive jackpot networks such as MegaJackpots from IGT at BetMGM.
Players can browse new slots, featured slots, exclusives, jackpot slots, and so on, or they can filter by provider. Game suppliers include DGC, Light & Wonder, IGT, NetEnt, Inspired, Everi, Anaxi, AGS, High 5, Play’n Go, Novomatic, Ainsworth, DWG, and Konami. Pages do not load quite as quickly as those at DraftKings or FanDuel, perhaps due to the size of the game library, but it is still a pretty accessible online casino.
4. Caesars Palace Casino slots
Caesars Palace Online Casino offers slot players a large welcome bonus, a strong rewards program and a reasonably broad variety of games. There are more than 700 slots at Caesars Palace Casino New Jersey, from studios that include Big Time Gaming, IGT, Lightning Box, NetEnt, ReelPlay, NextGen Gaming, Wild Streak Gaming, and WMS. The casino’s game library is smaller elsewhere, as is generally the case at legal online casinos. There are a couple of exclusives in the mix, including Caesars Fortune.
The lobby is bright, vibrant and full of colorful animations. One useful section highlights the top progressive jackpot slots, appearing in descending order of the top prize available at any given time. It hosts mega jackpot slots from IGT, such as Wolf Run, Siberian Storm, and Elephant King. There are also links to new releases, Megaways, Palace Picks, Diamond Selection and Sizzling Games, which aid the navigation process.
While Caesars Palace lacks the sort of variety BetMGM offers, it does have several key features that could appeal to slot players. For example, it offers 24/7 customer service via phone, live chat, and email, and the agents were quick to respond during our testing. The betting limits are broad, ranging from $0.01 per spin to $2,000.
5. Fanatics Casino slots
The Fanatics Casino app hosts approximately 150 slots from providers such as Big Time Gaming, IFT, Light & Wonder, and ReelPlay. Some of the most popular options include 88 Fortunes, Smash the Pig, Triple Diamond, and Wheel of Fortune Triple Extreme Spin.
The user interface is neat, clean, and uncluttered. We had no trouble finding specific slots when we tested the app, and they ran smoothly on iOS and Android devices, without any crashes or glitches. Fanatics doesn’t offer games on its website, so you can only play slots at Fanatics Casino if you download the app.
At the moment, Fanatics Casino struggles to compete with established rivals such as BetMGM and DraftKings Casino in terms of game variety. For example, BetMGM has more than 3,000 slots, including various exclusives. Fanatics Casino should appeal to beginners and anyone seeking a simple user experience, but it will need to increase the size of its game library to have any chance of dethroning the industry leaders.
The company has partnered with Boom Entertainment to secure exclusive content, and it could tie up supply deals with more providers in the future, so we expect the Fanatics Casino slots library to improve in the months and years ahead.
6. Bally Bet Casino slots
Bally Bet Casino offers more than 400 online slots in New Jersey and around 300 in Pennsylvania and Rhode Island. While Bally Bet Casino has a smaller portfolio of games than BetMGM, DraftKings, and FanDuel, the interface is clean, accessible and simple to navigate. Sections for trending slots, new slots, jackpots, exclusives and themes such as Western slots help organize the available games.
Parent company Bally’s Corp., which is based in Rhode Island, purchased a major UK online casino software provider named Gamesys a couple of years ago. It now has in-house development capabilities, so Bally Bet Casino now features exclusive, original slots such as Winfall Wishes, Tiki Island, Sapphire Sorceress, and various others.
It also offers the most appealing welcome bonus among legal online casinos. New customers who sign up using the Bally Bet Casino promo code (Coming Soon!) will receive a $50 no deposit bonus. Then, if they deposit $10 or more, they’ll also qualify for a reload bonus of up to $100 to cover any net losses in their first week of play. Bally Bet Casino also offers extra bonuses for all slot players, along with the Bally Rewards program.
7. Horseshoe Casino slots
Horseshoe online casino offers over 1,450 slot games for players in legal iGaming states. Many of theses games are developed by some of the most renowned game providers, including High5 Games, Caesars Digital, Light and Wonder, IGT, Greentube, NetEnt, White Hat Gaming, and Spinberry.
Horseshoe casino is owned and operated by Caesars Entertainment. Though the Horseshoe brand has existed in some form since 1951, it only entered the iGaming space just recently, launching in October of 2024. Horseshoe is the newest entrant to the iGaming space.
The most popular slots games on Horseshoe casino right now are Finn and the Swirley Storm, Gaelic Luck, Rainbow Cash Pots, and Reel Lucky King Megaways. Players can use Horseshoe’s sorting feature to organize games based on criteria like “High limit slots”, “Megaways”, “Trending Slots”, and “New Releases”.
Horseshoe casino also offers a new user bonus that allows players to claim up to $1,225 back in bonus bets after their first wager.
Online slot bonuses and promos
Most online casinos offer a welcome bonus to attract new customers. They may also provide regular bonuses to encourage slot play and to deter you from switching to a rival online casino. These are the main types of bonuses you may come across:
- Deposit match bonus: The casino will match a percentage of your initial deposit with bonus credits. You will need to complete a playthrough requirement on the bonus credits before they convert to withdrawable cash.
- Play it again bonus: Some online casinos offer to pay back any net losses you might incur during your first day or week as a customer. Most pay the refund in bonus credits, which will have a playthrough requirement, but some will pay it in cash.
- No deposit bonus: This type of sign-up bonus provides you with casino credits immediately after you create an account. There is no need to deposit or risk your own money to qualify. If you complete the wagering requirements, you can cash out what remains. Bally Bet Casino offers the best no deposit bonus right now, as new players receive $50 in bonus credits straight off the bat.
- Refer-a-friend bonus: DraftKings, for example, offers up to $100 in casino credits via its referral bonus. The person you refer needs to follow your link, create an account and make a deposit. The bonus you receive will depend on the size of that first deposit. The person you refer will receive an identical bonus.
- Bonuses for existing players: Many online slot casinos provide existing customers with ongoing bonuses. These can include bet-and-get promos. For example, bet $30 on a specific slot at BetMGM and get $10 in bonus credits. You may also find leaderboard contests, loyalty rewards and other promos.
- Reload bonus: This is similar to a first deposit bonus, but for existing customers. For example, a casino may offer a 20% reload bonus up to $100 if you deposit money into your account on a particular day.
Online slot bonus advice
It is important to read the fine print before claiming a bonus at a casino for playing online slots or other games.
Check the playthrough requirement of each casino bonus before you make any decisions. This will tell you what multiple of the bonus credits you will need to wager to convert them into withdrawable cash. For example, a $100 bonus with a 10x wagering requirement means you would need to place $1,000 worth of bets.
How to play online slots in 7 steps
The best online casinos make it simple for you to create an account and start playing slots. Just follow these steps:
- Choose one of the online slot sites we have recommended above. Follow the “play now” link or click the promo code to visit the site and claim the sign-up bonus.
- Fire up the slots site’s registration form and fill in your full name, date of birth, phone number, email address, home address and final four digits of your Social Security number. Choose a password. Make sure the promo code appears in the appropriate field.
- Accept the terms and submit the form. The casino will try to verify you. If it is unable to do so, or if it does not offer automatic verification, upload any additional documents that it requests to confirm your identity.
- Visit the online cashier and deposit money into your account. The site will then release the bonus credits if you have redeemed a deposit bonus.
- Select the “Slots” option on the homepage to browse the full library. Alternatively, head to a sub-category, such as Megaways or jackpot slots, or search for a specific game.
- Click on a game. You will see a paytable, which explains the payout rates for the various symbols, along with a description of the game.
- If you are happy, enter the game. Choose your bet amount and click to spin the reels. If certain matching symbols line up on one or more paylines, you will win, and your winnings will appear in your balance. Repeat as many times as you like, but remember to gamble responsibly.
How to choose the best casino for real money slots
There are lots of rival online slots casinos to consider in states such as Michigan, New Jersey and Pennsylvania. These are some of the key traits to look at when choosing an online casino:
- Game variety: Browse the slot library and make sure it includes the games you want to play. For example, if you like playing Megaways slots, high volatility slots or progressive jackpots, you can consider the breadth of options available. It is also helpful to look out for specific games if you have particular favorites.
- Exclusive slots: Most online casinos feature the same games from large providers like NetEnt and High 5, but the best casinos can also stand out by offering exclusive slots.
- High RTP slots: Slots with high theoretical payout rates can boost your chances of enjoying a successful session. We provide a list of some high RTP slots below.
- Bonuses: Promotions and loyalty rewards can also improve long-term chances of success when playing online slots. Consider the size of the welcome bonus, any available recurring promotions and the wagering requirements that you’ll need to meet.
- Payment methods: If an online casino does not offer your preferred payment method, it can be a deal-breaker. Visit the payments page at any casino site to scan the list of deposit and withdrawal options. You might also like to consider the payment limits, as some online casinos are more suited to casual players and others appeal more to high rollers.
Free vs. real money online slots
Some online casinos will let you play slots for free in demo mode with virtual credits. You can then play them for real money at any time. These are some of the key pros and cons of each mode:
| Real money slots | Free slot games |
| Offers the chance to win real-money playing online slots. | Playing in demo mode allows you to test the slots to determine which ones you might want to play for real money. |
| You often have a broader range of options at your disposal, as some slots are unavailable in demo mode. | You can extend your gameplay, as your own funds are never at risk. |
| Players can earn bonuses and rewards points while playing slots online for real money. | Some players feel that playing in demo mode lacks the same excitement when compared with real money play. |
| Success is never guaranteed, and you can lose money when playing online slots, so please gamble responsibly. | It can be frustrating to secure a win when playing in demo mode, as you will not earn a profit. |
Legal online slot casinos
Legal online slot casinos are available in six states. Such casinos need a license from the gambling regulator in that state, such as the New Jersey Division of Gaming Enforcement or the Michigan Gaming Control Board.
Software providers must also obtain licenses in each state to supply online casinos with slots. The list of licensed providers varies on a state-by-state basis, which means that the same online casino may offer different slots in each state.
Pennsylvania
Pennsylvania is the largest state with legal online casino gaming. However, it imposes a 54% revenue tax on online slots, compared to just 15% in New Jersey and 20% to 28% in Michigan. That has dissuaded some providers from launching in the state, so online casinos in Pennsylvania tend to have smaller slot libraries than those in neighboring New Jersey. At the moment, Pennsylvania is home to 19 online casinos.
West Virginia
Online slots have been legal in West Virginia since 2019. BetMGM launched the first licensed online casino in the state the following year. It now has eight rivals in West Virginia, including FanDuel, DraftKings and Caesars Palace. Online casinos in West Virginia have far smaller game libraries than those in states like New Jersey and Michigan. However, one quirk is that casinos tend to offer larger bonuses in the Mountain State.
Delaware
Delaware was the first state to allow online slot gambling, which it did in 2013. There are three online casinos (one from each of the state’s land-based racinos), but they all run on the same software and host the same games. Prior to January 2024, they were powered by 888 Holdings, and they offered fewer than 100 slots. However, Rush Street Interactive — the parent company of BetRivers — then signed a contract with the Delaware Lottery to replace 888. The BetRivers-powered Delaware online casinos now host more than 600 slots, as the company has tied up supply deals with many more software providers.
New Jersey
You can choose from 28 online casinos in New Jersey. Legal online casino gambling launched in the state in November 2013, and it has grown from there. Online casinos in New Jersey can feature games from a broad pool of suppliers, so they tend to have larger slot libraries than their counterparts in other states. For example, there are 3,217 slots at BetMGM New Jersey and 2,725 at BetMGM Michigan.
Connecticut
There are two places to play online slots for real money in Connecticut: DraftKings Casino and Mohegan Sun Casino. No other online casinos can launch in the state, so they will continue to hold a duopoly unless the state amends its online gambling law. The Mohegan Sun online casino is powered by FanDuel. It is a reskinned version of FanDuel’s online casino, and it is different from the Mohegan Sun online casino in New Jersey.
Michigan
Michigan casinos launched in January of 2021. There are a plethora of options for slot players looking to get into action, with a total of 15 legal casino apps in the state. Well-known brands such as BetMGM, DraftKings, FanDuel, and Golden Nugget compete with smaller, more local platforms like FireKeepers, Four Winds, and Eagle Casino, creating a dynamic, competitive industry.
Types of online slot games
There are thousands of online slots at some casinos. They may be grouped into a variety of sub-categories, which can aid navigation. These are some of the key types of online slots:
- Classic slots: Basic online slots that mimic the gameplay of the old-school mechanical slot machines in Las Vegas or Atlantic City. They often have just one payline, either three or five reels and very few additional features. Some players enjoy the simplicity and speed that these games offer.
- Video slots: These slots offer additional multimedia layers to create a more immersive experience. They also generally have multiple paylines. Video slots dominate at legal online casinos. They tend to offer lots of different themes, volatility levels, features and RTP rates.
- Megaways slots: Big Time Gaming, an Australian studio that Evolution Gaming purchased in 2021, created the Megaways feature in 2015. It revolutionized online slot play, as it allows for more than 100,000 paylines on a single slot. Many other studios now use the Megaways feature, and you will find dozens of these games at top online casinos.
- Progressive jackpot slots: A percentage of your wager amount goes into a communal pool each time you spin the reels on a progressive jackpot slot. One player will eventually land the top prize by matching the correct symbols, often within a bonus round, and the jackpot pool then begins from a small base once again. Some jackpot slots offer seven-figure payouts.
- Bonus buy slots: You can buy automatic access to the top bonus features on these slots. Doing so can increase the RTP rate of the game.
- 3D slots: Many video slots now boast 3D graphics. This does not alter the gameplay, but it can create a more visually arresting and immersive experience.
High RTP and online slot payouts
Every online slot has a return-to-player rate. This tells you the theoretical return that an average player would receive. For example, if the RTP is 95.8%, the average player would get back $95.80 out of wagers totaling $100. All results are random, meaning certain players win and others lose, but selecting games with high RTP rates will theoretically improve your chances of success.
The random number generators that provide the results at each online slot adhere to the stated RTP rates. They receive independent testing for accuracy and fairness, ensuring that they uphold the RTP.
The chart below highlights the games with the highest RTP rates at legal online casinos in the United States. Some of them, such as Blood Suckers, offer a high RTP percentage to all players. Others, including Medusa Megaways, require you to activate the bonus buy feature to benefit from the top RTP rate, while Barcrest slots like Monopoly Big Event require you to use the “Big Bet” feature to unlock the highest RTP percentage.
| Online slot | RTP | Casino |
| Monopoly Big Event | 99% | DraftKings |
| Blood Suckers | 98% | DraftKings, FanDuel |
| Codex of Fortune | 98% | BetMGM, DraftKings |
| Legend of Bigfoot | 98% | DraftKings, BetMGM |
| Dr. Jekyll Goes Wild | 98% | BetMGM, DraftKings |
| Starmania | 97.87% | FanDuel, BetMGM |
| White Rabbit Megaways | 97.7% | BetMGM, Golden Nugget |
| Medusa Megaways | 97.63% | DraftKings, Caesars Palace |
| Secrets of Atlantis | 97.07% | DraftKings, FanDuel |
| Halloween Fortune | 97.06% | BetMGM, BetRivers |
| Double Fancy 7s | 97.06% | BetMGM, FanDuel |
| Steam Tower | 97.04% | BetMGM, BetRivers |
| Gorilla Go Wilder | 96.94% | DraftKings, BetRivers |
| Guns N’ Roses | 96.98% | FanDuel, Caesars Palace |
| Blood Suckers 2 | 96.94% | DraftKings, FanDuel |

Online slots FAQs
You can play slots online for real money at legal casino sites and apps in New Jersey, Pennsylvania, Michigan, West Virginia, Connecticut, and Delaware. No other states permit legal online casinos right now, but we will provide updates if that changes.
DraftKings is the best online casino for slot players according to our rankings. It offers more than 1,000 slots in some states, including dozens of progressive jackpot games. New customers can also claim a large sign-up bonus and earn regular rewards, so it is a popular choice.
Start out by identifying a range of high-quality slots from reputable providers such as NetEnt, IGT, Light & Wonder, and Everi at a licensed online casino. You can then focus on factors such as the RTP rate, theme, volatility level and features when selecting an ideal online slot for your personal preferences.
The most popular online slots include Starburst, Gonzo’s Quest, Cleopatra, Wheel of Fortune and Book of Dead. They all came out years ago, but their popularity has endured, and they feature prominently at the top legal online casinos in the United States.
Blood Suckers, Starmania, Secrets of Atlantis and White Rabbit Megaways are among the online slots with the highest RTP rates. There are some slots with even higher payout rates, such as Book of 99 and Ugga Bugga, but they have not yet found their way onto licensed online casino sites anywhere in the US.
The RTP rate highlights the theoretical return that an average player would receive. For example, if a slot has an RTP of 96.2%, the average player would get back $96.20 from $100 worth of bets. However, the results are random, meaning that some players win and others lose.
The most volatile online slots include Big Bass Bonanza, Dead or Alive II, Extra Chilli Megaways and White Rabbit Megaways. Some players enjoy these slots, as they offer a greater potential for large payouts. However, the wins tend to be infrequent, so others prefer the regular, smaller wins at low volatility slots.
BetMGM typically has the largest jackpots among its slots. It hosts an in-house network of progressive jackpot slots, which it shares with sister sites PartyCasino and Borgata in some states. However, DraftKings regularly offers large jackpots, as well, so you may find higher prizes there at certain times.
