Use the in-depth reviews below to discover what makes these slots stand out, what players think, and all the need-to-know stats. Pros ✅ 3rd highest payout slot of 2023 (150,000 x stake max wins) ✅ More special symbols than previous Money Train slots ✅ Higher than average number of bonus features (20+) Cons ❌ Average win in main feature is 98.5 x bet The final installment in the Money Train series, Money Train 4 is a 6x6 grid slot with a scatter pays mechanism. With a high-octane theme and superb graphics, it boasts 20+ bonus features and you can win up to 150,000x your stake on every spin. 💡 Editor's insight: For me, Money Train 4 was the best release of 2023. Bonus symbols, like the Upgrader, can cause chain reactions across the reels leading to huge wins. The theme is a bit Mad Max too, which suits the high volatility. 💬 Provider insight: “Money Train 4 offers the very best in what has been a brilliant series of games, which is reflected in reviews from leading streamers and affiliates. We hope that players love this new Money Train experience.” - Shelley Hannah, CPO at Relax Gaming ⭐ Casino.org rating: 5/5 | 🏅 Best slot for: Original bonus features Pros ✅ Much higher max wins than the original Starburst slot (500 x vs 200,000 x stake) ✅ Easy to understand mechanics ✅ Offers familiar and iconic graphics Cons ❌ No free spins round A more recent update of the hugely popular Starburst slot, Starburst XXXtreme features all of the galactic graphics you know and love but with souped-up payouts. Starburst wilds are still present but now come with multipliers. Plus, Starburst XXXtreme offers 200,000 x stake max wins. 💡 Editor's insight: Though Starburst still draws in players, I much prefer Starburst XXXtreme. Wild multipliers combine to be worth up to 450x, and the max win amount definitely appeals. Higher payouts mean higher volatility, however. Don't expect as zen an experience as the original. 💬 Provider insight: “Everyone knows the Starburst name. It’s been a slot favorite for years. We’ve worked hard to keep classic features and the team has done a great job at incorporating them into an XXXtreme version." - Todd Haushalter, CPO at Evolution ⭐ Casino.org rating: 5/5 | 🏅 Best slot for: players looking for a twist on a classic Pros ✅ Decent hit frequency rate (37.47%) for a high volatility slot ✅ Unlimited win multiplier in bonus round ✅ Most popular Megaways slot since 2016 Cons ❌ Graphics look a little dated One of the most popular Megaways slots available in the US, Bonanza Megaways uses Big Time Gaming's patented Megaways mechanism to offer you 117,649 ways to win. Played over 6 reels, it comes with 3 bonus features. Cascading wins enhance the base game, while the free spins round comes with added multipliers. 💡 Editor's insight: I always enjoy Megaways titles but Bonanza Megaways is something of a cult classic. Your biggest winning opportunities come during the free spins round, as multipliers can give you 26,000x stake wins. Although the graphics are a little dated now, in my opinion, the slot still deserves a place on our recommended list. 💬 User review: “Try Bonanza by Big Time Gaming!! Cascades + Megaways = insane potential! - Glimmer_Snuggle_bear, Reddit ⭐ Casino.org rating: 4.9/5 | 🏅 Best slot for: Megaways fans Pros ✅ High RTP rate up to 96.5% ✅ Triple the max win amount (15,000 x stake) of original Gates of Olympus slot ✅ Available at most US casinos Cons ❌ Theme could be more original Released in 2023, Gates of Olympus 1000 takes the original Pragmatic Play slot to a new level. While the design and theme are almost identical to the well-loved Gates of Olympus slot, this new version comes with higher multipliers and the chance to win up to 15,000x your bet per spin. Played on a 6x5 grid with a scatter pays mechanism, tumbles create consecutive wins too. 💡 Editor's insight: Pragmatic Play has released a series of '1000' slots recently, but Gates of Olympus 1000 is by far my favorite. The graphics still look sharp and the payouts are three times higher than before. This is thanks to a rewarding 1000x multiplier which can land randomly during the base game or free spins. 💬 Provider insight: “Zeus is back with a bang in this striking sequel to our iconic ancient Greek-themed release. Gates of Olympus 1000 takes one of Pragmatic Play’s most popular and successful slots ever and massively boosts its win potential." - Irina Cornides, COO at Pragmatic Play ⭐ Casino.org rating: 4.6/5 | 🏅 Best slot for: scatter pays with a classic theme Pros ✅ Up to 14,400 ways to win via Playtech's unique 'Ways Boost' feature ✅ Multipliers combine in bonus round to give bigger wins ✅ Most popular slot for US players in our top 5 Cons ❌ Slightly lower than average RTP rate With 6 reels and 4,096 ways to win, Buffalo Blitz II is one of the best slot sequels around. It's highly volatile, and comes with 5x multiplier wilds in the base game. Land scatter symbols to trigger the free spins round, and win up to 100 free games. During the bonus round, the unique Ways Boost engine allows you to play with 14,400 ways to win. 💡 Editor's insight: Although I always loved the original, I much prefer playing Buffalo Blitz II. Multipliers can land during the base game, which is quite rare. As this is a high variance slot, however, I recommend playing when you have a bigger bankroll that can see you through any dry spells. 💬 User review: “Deposited $5, and was playing Buffalo Blitz II. Did good so upped my bet. I got it up to $1K, and when I got down to $900, I cashed in!" - wessdude79, Reddit ⭐ Casino.org rating: 4.9/5 | 🏅 Best slot for: high volatilty fans "When choosing a slot machine, there are three things to look for. If you’re playing for fun, look for games with lots of bells and whistles. This includes bonus rounds, frequent pays, and lots of animation, color, and music. If fun and profit are your goals, then look for medium volatility games with fewer pays but better value. If profit is your main motivation, then look for high-volatility games which pay less frequently. When these slots do hit, wins will be of a higher value." We constantly test new slots to keep our recommendations up to date. Want to know which titles we're expecting to earn a place on our list of the best slots for real money? Check out the most hotly anticipated slots of 2024-2025 and their release dates. As someone who used to work on the inside at an online casino operator, I’ve seen my fair share of slot releases; some groundbreaking, some... not so much. In 2025, I'm looking forward to Invading Vegas Revenge on Mars by (Play’n Go). The theme is super-American, and it's one of Play'n Go's more inventive efforts. Look out for it on February 6th! The other one I'm looking out for is Bigger Bass Splash by Pragmatic Play. The original is already a classic, so I'm surprised we had to wait this long for a proper sequel. Just my two cents, but both of these games feel promising. Let’s see if they deliver! If you're looking for the hottest releases, check out our dedicated new slots page. Here you can play the latest game demos for free and find the best casinos for playing new slots in the US. Now you know which online slots we recommend, understand how we chose them. Our rating system reassures you that these are actually the best slot games that pay real money, benchmarked against other titles and industry stats. What's more, it can help you spot your own top slots. Before anything else, we check the slot's return to player (RTP) rate. Slots have an average RTP of 96%, so anything below this won’t make the cut. Marching Legions by Relax Gaming and 1429 Uncharted Seas by Thunderkick win this round, with industry-leading RTPs of over 98%. 💡 Expert insight: The return to player rate represents the percentage a slot will pay back to players over time. While this is a theoretical rate, calculated over millions of spins, it’s still important. Simply put, the higher the RTP, the better your chances of winning in the long run. All slots have a maximum win amount, per spin. This is expressed as a multiplier (e.g. 5,000x stake) though it’s not just the payline wins that contribute. Max win amounts are usually only achieved via bonus features working together. For example, Money Train 4 offers max wins of 150,000x your stake. These come via the Money Cart Bonus feature where 20 special symbols can upgrade wins. 💡 Expert insight: The higher the win figure, the more you can theoretically win per spin and the more rewarding the slot. While we've seen maximum win amounts drop in recent years (10,000x your stake is considered a decent stat), providers such as Relax Gaming and NetEnt still produce slots with huge winning potential. Bonus features give you extra chances to win real money slots. As such, it's easy to think the more bonus features, the better. However, they must work well together and be easy to understand too. 💡 Expert insight: Money Train 4 boasts 20+ features confined to one bonus round, so they're not too overwhelming. Starburst XXXtreme fairs well too. While the bonus features are limited, they trigger often and are very simple. Unique themes and design choices make the best slots stand out. For example, 4 Fantastic Fish in Egypt spins the classic Egyptian theme on its head. It features animated symbols and you can play in 'Big Reel Portrait Mode' for an immersive mobile slot experience. 💡 Expert insight: In 2024, we don't want to see a slot's graphics described as 'smooth' or 'crisp' - that's the bare minimum you should expect! Instead, look for exciting cut-scenes more akin to Xbox games than one-armed bandits. These keep you engaged and motivated - hitting spin repeatedly gets old fast! Innovative online slots will feature interesting layouts and payout mechanisms. For example, slots with the Megaways mechanism by Big Time Gaming are incredibly popular. These can offer up to 586,971 ways to win. Other examples include the Infinity Reels mechanism by Relax Gaming and scatter pays slots. Overall, if a slot offers something fresh, it gets points from us. 💡 Expert insight: New game providers looking to make a splash on the market will be among the ones to watch for the most cutting-edge features. Last but by no means least, we never put your bankroll at risk. Any slot featured on Casino.org will be properly licensed and tested for fairness. For instance, NetEnt Americas is licensed by the New Jersey Division of Gaming Enforcement, the Pennsylvania Gambling Commission Board (PGCB), and the West Virginia Lottery (WVL). 💡 Expert insight: The best slot software providers are part of eCORGA. eCOGRA is an independent testing body that ensures game results are random and RTP rates are correct. Software providers don't need to be eCOGRA certified to gain licenses, so this extra certification is a huge mark of trust. Finally, we decided on the overall player experience. Some slots may have all the bells and whistles, but it comes down to the gameplay. Once we know that the game ticks all the boxes, this is the point at which we will recommend it to our players. 💡 Expert insight: With 30 years of experience reviewing slot games, our team has played thousands. You will not find a team with more insights into how slots really perform than on this page. Our experts have chosen the five best slot sites for US players. Read the reviews below and make an informed decision based on the number of slots it offers, software providers, RTP, and its unique Casino.org rating. ✅ Unique rewards program | Highest win rate (97.63%) of our top picks | Largest welcome bonus on our shortlist ❌ 70% of our top casinos pay out quicker 🎰 Top slots: Guns 'n' Roses (NetEnt), Money Train 4 (Relax Gaming), Rainbow Riches (Barcrest) Caesars Palace Online Casino is one of my favorite places to play slots. It boasts 700+ slots from 21 providers. In comparison, the average US slot site offers games from around 15 providers. Try heavy-hitting slots from Relax Gaming, or opt for classics from Barcrest. The choice is yours. 💬 User review: "The bonuses and promos at Caesars Casino Online are pretty good. They totally met my expectations and added to the fun." - Feeling_Yak7183 - Reddit user, January 2024 Read our full Caesars Palace Online Casino review. ✅ Highest number of slots on our list | Above average number of progressive slots | Accessible 1x wagering on bonuses ❌ Does not offer a no-deposit bonus 🎰 Top slots: Wanted Dead or a Wild (Hacksaw Gaming), Colt Lightning Firestorm (Play'n GO), Nitropolis (ELK Studios) BetRivers comes complete with 1,400+ slots from great providers such as Hacksaw Gaming and IGT. This slot site also boasts over 100 jackpot slots, including NetEnt's Mega Fortune and Divine Fortune. With so many slots, I found it impressive that the casino's overall win rate is above average at 96.96%. That said, this is slightly lower than Caesars Place. 💬 User review: "BetRivers is a solid choice for newbies and pros alike. The promos and game options are definitely awesome." - karmaahmad - Reddit user, January 2024 Read our full BetRivers casino review. ✅ Wider range of software providers (25+) than most US casinos | 15+ bespoke slots | Larger than average referral bonus of $500 ❌ Slowest average payout speed of our top casinos 🎰 Top slots: 9k Yeti (4ThePlayer), Lobstermania 2 (IGT), Bonanza Megaways (BTG) Most US casinos have around 800 slot games, but Golden Nugget exceeds this with over 1,000. With 25+ software providers, I enjoyed seeing names like IGT and NetEnt alongside smaller brands such as AGS. Homegrown exclusive games also allow Golden Nugget to stand out from the crowd. 💬 User review: "I've been happy with Golden Nugget for a long while, their daily and weekend bonuses were great." - Tim Rownan - Reddit user, February 2024 Read our full Golden Nugget casino review. ✅ Generous $25 no deposit bonus | 40+ exclusive slots | Lower than average wagering requirements (1-15x) ❌ Lowest overall payout rate of our top sites 🎰 Top slots: MGM Grand Millions (created in-house), Cleopatra MegaJackpots (IGT), Hellcatraz (Relax Gaming) While BetMGM offers fewer software providers than other slot sites on this list, there are still over 800+ high-quality slots to play. Providers such as NetEnt, Relax Gaming, and Play'n GO feature on the casino's roster, plus you can enjoy slots exclusive to the BetMGM / Bwin.Party network. With a complete MegaJackpots suite from IGT to boot, it's my favorite slot site for jackpot slots. 💬 User review: "It's my favorite place to gamble. Love the variety of slots. Fast payouts. I've been using them for 2 years now and never had a problem." - Tiffany Brad - Google Play Store review Read our full BetMGM casino review. ✅ 2nd highest win rate on our shortlist | 60+ Megaways slots | 40+ exclusive DraftKings slots ❌ Smallest welcome bonus on our list 🎰 Top slots: Ted Jackpot Royale (Blueprint), Buffalo Blitz II (Playtech), Gonzo's Quest Megaways (Red Tiger) Although DraftKings Casino offers the lowest number of slots on this list (500+), the good news is that you can play over 40 DraftKings exclusives. This includes titles like NBA Slam Dunk Roulette, Playboy Diamonds, and Loki's Luck. The casino's slot collection covers all themes and slot types—for instance, a quick search of Buffalo-themed slots found over 18 titles, including Buffalo Blitz II. You can also enjoy 60+ Megaways slots. 💬 User review: "They don't have the most impressive game library, but they offer a lot of regular awesome promos, withdrawals are instant 7 days a week, and they add loyalty bonuses for your losses." - Chirs WS - TrustPilot review Read our full DraftKings casino review.

In the following sections, learn about the most popular slot types in the US, the best software providers, and the main differences between playing for free and real money. Essentially, we help you to navigate any bustling slots lobby with ease. When you enter a slots lobby you'll find games sorted by category. Real money slots range from classic three-reel games, to colorful and feature-packed video slots. This gives you a huge amount of choice but it can be hard to know where to start. Take a look at the most popular online slot types below. Learn how each works and try the best of each variant with free demos. Recommend by our experts, these offer great examples of the features you can expect. As the name suggests, three reel slots are played over just three reels. In general, they don't have many paylines and often feature old-school symbols such as 7s and bars. To win, simply line up three matching symbols on a single payline. In addition, Most three-reel slots don't include bonus rounds and may not even feature many special symbols. 💡 Expert insight: Many older slots are three-reelers but there are great new titles too. Toro 7's by ELK Studios, for example, mixes this traditional layout with new features. 🎰 Best three-reel slots: Toro 7's by Elk Studios, Break Bones by Hacksaw Gaming, Mega Joker by NetEnt Toro 7s Most video slots have five reels or more. This simply refers to the number of columns in the game, and these spin independently of each other. Paylines here can range from 10 to well over 100. Winning combinations are generally formed by landing 3 or more matching symbols across consecutive reels. Expect a wide range of features such as wilds, scatters, and bonus games. 💡 Expert insight: With these types of slots, your bet is usually set per line, although you have to play all paylines. Play a 5 reel, 10 fixed payline slot, and you can bet $0.10 per payline. This means each spin costs $1 in total. 🎰 Best five-reel slots: Starburst by NetEnt, Book of Dead by Play'n GO, Big Bass Bonanza by Pragmatic Play Starburst Megaways is a game engine/mechanic created by Big Time Gaming (BTG). Megaways slots are played with up to 6 reels where the number of symbols on each reel changes with each spin. The number of symbols on each reel creates the number of available ways to win. For example, in a 117,649 Megaways slot, each reel can contain between 2 and 7 symbols. If each reel displays 3 symbols each, the number of Megaways will be 729 (3^6=729). Seeing 7 symbols on each reel, however, gives you the maximum 117,649 Megaways (7^6=117,649). 💡 Expert insight: Although the Megaways mechanism was first developed by BTG, they have licensed it out to many other providers. This means you can play Megaways versions of many popular slots. 🎰 Best Megaways slots: Bonanza Megaways by BTG, Blood Suckers Megaways by Red Tiger, Buffalo Blitz Megaways by Playtech Blood Suckers Megaways Grid slots, also known as cluster pays slots, are played on grids instead of reels. They do not feature paylines and instead, to form a win, you must land matching symbols in a cluster formation. Symbols must be next to each other, touching either horizontally, vertically, or diagonally. The bigger the cluster, the bigger the win. Grid slots almost always feature cascades/tumbles. Winning clusters are removed from the reels, allowing them to be replaced by new symbols. This can lead to consecutive wins if you land further winning clusters. 💡 Expert insight: Grid slots have soared in popularity and now come in all shapes and sizes. Slots like Dam Beavers by ELK Studios take this to the extreme, offering expanding grids and different playing levels. 🎰 Best grid slots: Dam Beavers by ELK Studios, Lure of Fortune by Relax Gaming, Cluster Tumble by Relax Gaming Dam Beavers Scatter pays slots feature a specific mechanic where winning combinations can be formed by symbols appearing in any position on the reels, instead of along paylines. You could have 1 symbol on each reel for example. 💡 Expert insight: Whilst scatter pays slots are usually played across a grid, they aren't to be confused with grid slots. The difference is the way symbols pay out - in random positions vs in clusters. That said, in most cluster pays slots, winning symbols are also removed from the board by a cascade/tumble feature. 🎰 Best grid slots: Money Train 4 by Relax Gaming, Gates of Olympus 1000 by Pragmatic Play, Sweet Bonanza by Pragmatic Play Gates of Olympus 1000 Progressive jackpot slots are individual slots, or series of slots, that share a jackpot prize pool across a network of casino sites. Each time a player bets on the slot, a portion of that bet goes towards the jackpot. As players across the world are adding to the jackpot constantly, progressive jackpot figures can grow quickly. Progressive jackpots seed at different amounts. For instance, the Mega Fortune Mega Jackpot seeds at $150,000. This is the minimum you can win. 💡 Expert insight: The world’s most famous progressive jackpot slot is Mega Moolah by Microgaming. Unfortunately, this slot is not available in the US. 🎰 Best grid slots: Mega Fortune by NetEnt, Age of the Gods by Playtech, Space Miners Dream Drop by Relax Gaming. Age of the Gods Branded online slots are games inspired by movies, board games, television shows, or even cartoons. Branded slots don't feature any specific mechanisms or layouts, so expect them to come in all shapes and sizes. Providers like NetEnt and Playtech are well-known for producing a lot of branded titles. 💡 Expert insight: Branded slots often have lower RTP rates than regular titles. This is because the slot provider must pay a licensing fee to the movie/TV studio. What's more, a studio may pull a branded slot at any time. The Marvel slots by Playtech, for example, were once huge. However, when Disney bought the Marvel brand, they ceased to exist. 🎰 Best grid slots: Jurassic Park by Microgaming, Narcos Mexico by Red Tiger, Breaking Bad: Cash Collect & Link by Playtech Jurassic Park Slots lobbies may also be sorted by software developers. These are the studios that create the games, and each casino offers titles from a range of developers. Each software developer has its own style of graphics and features. Below, you can learn more about the most popular brands at real money slot sites in the US. NetEnt has been creating games for more than 25 years with online slots like Starburst and Dead or Alive 2 in its portfolio. It was also the first brand to release a grid slot, with Aloha! Cluster Pays in 2018. In 2020, NetEnt merged with Evolution alongside other studios like Red Tiger.

Here's a few of the most popular casino slots this January. Practice and play for fun, then deposit to be in with a chance of winning real money. If you choose to play slots for real money, paying attention to the RTP rate is key. As we mentioned earlier, RTP rates represent the amount you would win back from your bets over a long period. For example, a slot with a 96% RTP rate will pay you back 96% of your stakes, in time. Wager $100 and you’ll get $96 back on average. Naturally, short-term results are variable and RTP rates are theoretical. However, in general, the higher the RTP rate, the better paying the slot. Check out the highest RTP slots in the US below. For context, the average payout on a slots game is 96%. Now you know everything about online slots in the US, it's time to get started. Before you do, consider these top tips from our Content Editor, Daisy. The basic concept of spinning the reels to match symbols and win is the same with online slots and physical slot machines. The key difference with playing slots online is that the variation of games will be wider, and you'll find that most online slots offer more reels and paylines.
