Examine what makes these slots stand out, what players think, and all the need-to-know stats.

Money Train 4 by Relax Gaming

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: fearless players hunting big wins

Starburst XXXtreme by NetEnt

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

Bonanza Megaways by Big Time Gaming

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

Gates of Olympus 1000 by Pragmatic Play

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

Buffalo Blitz II by Playtech

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

Our top slot sites reviewed

Take a closer look at our top slot sites for US players. Discover why they're so great for playing slots, their drawbacks, and what existing players think.

Getting started at real money slots sites

If you want to play real money slots at online casinos in the US, just follow these simple steps. Spinning the reels couldn't be easier!

Slot game symbols and bonus features

Master the most common special symbols and bonus features you will find in online slots.

🔥 Special symbols in online slots

• Wild symbols: These can be found in most slot games and substitute for any paytable symbol to create a winning combination. Wilds can also carry cash values which are paid when you form a combination of wilds along a payline.
• Scatter symbols: Match three or more scatters anywhere on the reels to unlock a special feature. This could be a free spins round or a bonus game.
• Multipliers: Multipliers, as their name suggests, times your total win by a specific value. Multipliers may be found in the base game or a bonus round.
• Expanding wilds: Expanding wilds are similar to regular wilds, though they can expand to cover a whole reel. This gives you plenty more opportunities to create winning combinations.
• Sticky wilds: These wilds remain in place until you get a winning combination, or throughout a bonus feature.
• Modifier symbols: These symbols may change the size of a reel, the number of reels in the game, the payouts of a certain symbol, or replace low-paying symbols with higher ones. Ultimately, modifiers can do just about anything.

💰 Online slot bonus rounds

• Free spins feature: You’ll get a number of free spins, allowing you to play without placing extra wagers. Free spins are often played out on a different game screen and may come with multipliers.
• Respins feature: This gives you a second chance at creating a winning combination, or allows you to create consecutive wins. Winning symbols may be held and respins may continue until no new wins are formed.
• Pick me feature: This is a simple bonus round where you reveal objects to collect cash prizes.
• Trail feature: Roll a die or spin again to work your way around a trail. Along the way, pick up extra prizes depending on where you land. Generally, the further along the trail you get, the bigger the prizes.
• Gamble feature: Choose to gamble your wins to play on in free spins or to multiply wins. Common gamble features include picking a card, higher or lower, gamble wheels, or coin flips.
• Bonus buy: In some slots, you can simply buy your way into a bonus round for a fixed price. This allows you to bypass the base game. though it can be expensive.

💡 Expert insight: This list is by no means exhaustive. Slots providers are constantly coming up with new bonuses and features to beat the competition. Always read the paytable carefully before playing to understand what's available and how it works.

Online slots by highest RTP in 2024

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%.

Slots bonuses and promotions at US casinos

Most online slot sites in the US will offer you a welcome bonus or a sign-up bonus when you register for the first time. Usually, this bonus is a percentage of your first deposit, but it may be a free spins bonus too.

This isn't the only reward you can expect as a US slots player, however. Check out these common slots promotions and offers:

• Regular free spins: Just like free spins bonuses on sign-up, regular free spins give you a certain number of free games to spend on a specific slot or range of slots. Slot sites use these bonuses to celebrate new slot launches or new providers. Free spins usually come with wagering requirements but, at the best US casinos, these are no more than 1x.
• Slots tournaments: As their name suggests, slots tournaments pit you against against other players. Play selected slots during the tournament period, and win points for winning spins, bonus round triggers, and more. Climb the leaderboard to secure a prize.

Expert tips for playing real money slots

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.

• Choose slots by RTP and volatility

  Before I play a slot, I always check the return to player rate. If it's below 96%, I'm likely to give it a miss. The higher the RTP rate, the better the long-term payouts. However, it's also useful to factor in volatility. If I want to play for longer, I'll choose low-volatility games that pay out frequently. If I've got the bankroll to survive a dry spell, I'll choose high volatility slots that pay out large amounts once in a while.

• Choose slots you enjoy

  Despite the fact I always check the stats, it's equally important to play games you actually enjoy. With thousands of slots out there, there are themes and features for everyone. Personally, I enjoy unique themes with new mechanisms - the more absurd the better. Many players enjoy simple slots, however, so figure out what works for you.

• Practice with free demos

  If you are opting for slots with new bonus features, always play free demos first. They allow you to understand exactly what's going on, and how the slot pays out, without risking your bankroll. Once you're comfortable, you can give them a spin at a real money slot site.

• Use bonuses and promotions to try new games

  Many top slot sites offer free spins to new players. They may also run promotions when new slots launch. This is the perfect opportunity to step outside your comfort zone and try something different. Remember to read the T&Cs, however, as some slots are excluded. For example, wagers on Blood Suckers by NetEnt often won't contribute towards wagering requirements as the slot has such a high RTP rate.

• Play at trusted US slot sites

  I only ever play at slot sites with positive user and industry reviews. Naturally, it's easier for me to find these sites (as I do the reviewing!) but you can use our list instead. All of our recommended slot sites are guaranteed to provide a great slots experience.
