Best BetOnline Slots for US Players Reviewed

Now it's time to get deep into the weeds and learn more about our top-rated games. This section of our guide contains several reviews of the best slots to play at BetOnline.

Merge Up (BGaming)

There's a lot to love about Merge Up, a BGaming slot released in October 2023. First, it's among the best-paying BetOnline slots, with a return to player rate of 97.25%. When you consider that 96.00% is regarded as the industry standard, you can see that this 6x6 slot is on the loose side.

The gameplay is simple, but it's guaranteed to keep you returning for more. Just match the gemstones in clusters to earn rewards. In addition, any winning symbols will vanish from the grid, allowing new ones to fall in and replace them. This can lead to additional combinations worth up to 5,000x your bet. A very funky soundtrack backs all of the action.

The only minor downside to our nomination for the best BetOnline casino game is the high level of volatility. While that does keep things exciting, it might only suit some people's bankroll. However, playing this slot for as little as $0.20 per spin is possible, so there's certainly something there for lower-staking players.

Greedy Goblins (BetSoft)

Coming second on our list of the best slots on BetOnline is Greedy Goblins by BetSoft. Its classic 5x3 layout, nicely balanced volatility, and $0.02 minimum spin limit make it the perfect starting point for new players. However, more seasoned slot fans will appreciate the maximum bet size of $150.

Gameplay is uncomplicated. Match symbols on any of the 30 paylines to secure a return. However, watch for the Gold Coin bonus, which can result in cascading symbols and valuable chain reactions.

Released in September 2014, this game remains as popular as ever today. That's largely down to its simple but engaging gameplay. But it's also worth noting the impressive 97.20% RTP, which makes this title one of the best payout slots on BetOnline.

Choco Bunny Hop (Urgent Games)

Urgent Games is a slot developer flying under the radar, but BetOnline has undoubtedly realized the studio's potential. Choco Bunny Hop is a charming and visually appealing game that exemplifies the team's creativity.

Released just in time for Easter 2023, the reels are filled with an abundance of sweet treats and chocolate rabbits. The slot grid features a classic 5x3 layout, while the free spins game and multipliers are familiar bonus elements for slot fans. A minimum bet of just $10 will appeal to casual players, though playing for up to $50 a time is possible.

The game's volatility is on the high side, but there's an appealing enough top payout of 6,500x up for grabs. However, a big reason this is one of BetOnline's best slots in its library is the generous 97.00% RTP.

Monster Pop (BetSoft)

Released in March 2020, this colorful slot stars a collection of monsters that look more like aliens in truth. Whatever they are, they're much cuter than they are scary. Nevertheless, your job is to capture them in clusters, remove them from the grid, and earn cash prizes.

Collect three flaming spheres, and the scene changes to a hellish backdrop, where you'll play the free spins bonus. The Monster Cloner feature can be valuable, too, as this will expand the grid to a possible 13x13. Just $0.25 is required to spin the reels, though a maximum bet of $25 is possible.

Regarding volatility, Monster Pop is a nicely balanced game with a medium variance level. However, its 97.07% RTP is much better than average, making it one of the best slots on BetOnline overall.

More significant Cash Win (Rival)

Slots are just as traditional as Bigger Cash Win, based on old-school fruit machines. As such, you can expect classic slot symbols on the 3x3 reel grid, including cherries, Lucky 7s, and the iconic BAR signs.

Like many online slots, this medium-volatility game features a scatter symbol. Drop two of these onto the reels to trigger the slot's main bonus. Here, you'll spin a wheel of fortune that can award cash prizes and up to 15 free spins.

Although the RTP of 95.86% is not the biggest, this is still among the best slots on BetOnline. Since its release in May 2022, the game has proven to be a top performer and an all-around fan favorite. That's as much down to its nostalgic vibe and simple gameplay as anything else.

Beast Band (BGaming)

Get ready to rock with a series of colorful characters from the animal kingdom. This talented band is on a world tour, and you can secure VIP tickets to join them backstage and land a top prize of 7,500x.

This July 2022 release by BGaming is one of the best slots on BetOnline for several reasons. Not least the 96.83% return to player rate, which places it among the best-paying slots BetOnline can offer. You can spin the reels from $0.20 to $12, making it ideal for more casual players or beginners.

However, it's all about the fun theme with this medium to high volatility game. You'll surely love these musical mammals, from the lion lead singer, with his 1980s glam rock look, to the pink-haired punk pig on drums.

April Fury And The Chamber Of Scarabs (BetSoft)

If there's one issue with BetOnline slots, it's the lack of titles from award-winning developer Play'n GO. They are, of course, famous for their Rich Wilde series, which gave the world the favorite "Book of" slots format. Although you can't join Rich on his Egyptian adventures, you can undoubtedly accompany April Fury, BetSoft's equivalent.

April Fury and The Chamber Of Scarabs attempt to replicate Rich Wilde's success. But they've done a great job, and this August 2023 is now one of the best games on BetOnline.

While scatters are the key to unlocking the free spins bonus, you'll want to collect scarabs for a chance at the Hold & Win jackpot. With its 5x4 layout, the highly-volatile slot offers a 4,000x maximum potential win. The RTP is above average too, clocking in at 96.20%.

Battle Of Rome (Arrow's Edge)

The final game to appear in our compilation of the best slots on BetOnline, Battle Of Rome, was released in January 2021. At 95.93%, it's the lowest-paying title featured in this guide regarding RTP. But it's one of our favorites to play for various reasons.

First of all, it's an all-way pay slot. As such, you can also line up symbols from right to left. Most traditional slots only pay one way, from left to right. So, although there are 3,125 ways to win, this is effectively doubled. The maximum potential payout from the standard game is only 1,000x, but a mini progressive jackpot is usually worth up to $10,000.

Battle Of Rome has a relatively high level of volatility, so it will only be for some. But there's a lot to enjoy with a popular theme of ancient Rome, an engaging bonus round, simple gameplay, and a dramatic soundtrack.

About BetOnline

Launched in 2004, BetOnline is one of the most reputable offshore casinos, licensed by the government of Panama. Having started life as a sportsbook, it has since launched an online poker room and a first-class casino with over 750 games to enjoy.

In addition to providing some of the country's most competitive sports betting odds, there's a live dealer casino powered by no fewer than three different suppliers. However, our article focuses on the library of approximately 600 video slots. This includes progressive jackpot games, a variety of penny slots, and high-RTP titles.

How We Chose the Best Slots To Play On BetOnline

Now that you know about the top BetOnline casino slots, let's discover precisely why we chose them. Our expert team considers a range of factors when reviewing slots. However, the best games consistently do well in the following crucial areas.

Return To Player

When identifying the best BetOnline slots with high RTP, the starting point for our expert team is usually the RTP. This value tells us the return to player rate, which is the theoretical long-term payout of a game. Naturally, the higher that number is, the better our chance of winning some money.

For instance, if the RTP is 97.10%, the machine returns $97.10 of every $100 taken in. Of course, every individual spin is random. But play for long enough, and you'll find that the game nears its accurate RTP. These figures are certified by reputable third-party software testing labs to ensure they're fair and honest.


Closely linked to RTP rates, a game's volatility tells us how prizes are paid. Sometimes known as variance, a slot's volatility is how frequently it pays out. Higher-volatility games might make you wait more extended periods without dropping a prize. However, when they do, the value of those rewards tends to be greater than average.

On the other hand, lower-volatility games are well suited to players with smaller bankrolls or those who are prone to tilt. They pay out much more often, even if the prizes are smaller than other slots. Many of our recommended BetOnline casino games offer well-balanced volatility levels in the "medium" bracket.


There are two possible slot jackpots, though, of course, only some games have one. Some titles offer a fixed jackpot, just a specific value earned by achieving a particular feat. This usually matches a set number of special symbols, though it could also be triggered randomly.

A progressive jackpot, meanwhile, continues to grow over time. These can become extremely valuable, such as the Mega Moolah series by Microgaming. Their Mad Game once paid a world record sum of almost $17 million! Sadly, these titles aren't available at this particular casino. However, several of the best-paying slots on BetOnline do feature some jackpots.


Only some have a massive bankroll, but not everyone is a casual gamer looking to blow off steam with $10. A game must cater to as many players as possible, no matter how deep their pockets might be.

That's why the best slots on BetOnline offer a wide range of stake limits. That could be a few cents per spin to more than $100 per play. We also like to see some flexibility in the number of paylines, giving players as much control as possible.


So far, our desirable qualities have focused on the potential rewards. Of course, winning is excellent, and it's a big reason why many of us play online casino games. But ultimately, slots are meant to be a form of entertainment. So, if the game isn't any fun, why would you continue to play it?

The recommended BetOnline slot machines featured in this guide offer engaging themes with colorful visuals and entertaining soundtracks. What's more, you'll find a plethora of innovative gameplay mechanics and bonus features that help keep these games fresh and exciting.


That brings us to another important consideration when assessing the best BetOnline.ag slots: features. We aren't just referring to the basics, like wilds, scatters, and free spin bonuses.

These days, you'll find slots with all kinds of innovative game engines, such as Megaways or Infinity Reels. It's also increasingly common to see avalanche, tumble, and cascade features. Some slots remove the idea of paylines, opting for cluster pay systems. At the same time, others pay in both directions rather than the traditional left-to-right. Anything a little different will keep things interesting.

What Makes BetOnline So Good for US Players?

We've already discussed what makes a great game. And thanks to our series of mini BetOnline slots review articles, you now have a good selection of titles to try. But why should you play them at this particular casino? In the following section, we'll explain precisely why BetOnline is an excellent choice for slot fans. Even players from the USA commonly recognize BetOnline as a casino like Bovada.

Range of Games

Online casinos can only claim to be an excellent place to enjoy slots if they have a few games to sample! In addition to the aforementioned best slots on BetOnline, this site is equipped with around 600 more entertaining and potentially rewarding titles. Whether you want progressive jackpots, classic fruit machines, or penny slots, BetOnline has you covered.

As if that weren't enough, there are dozens of animated table games to try, including classics like roulette and blackjack. The slots library is also supported by several innovative products like crash games, plus number games such as keno. A fantastic live dealer casino offers lottery-style game shows and innovative sports-themed products.

Bonuses and Loyalty

All good modern casinos offer a generous signup incentive and several ongoing loyalty rewards to try and retain their customers. BetOnline is no different, starting with the $3,000 new casino player registration package. That consists of three distinct 100% match bonuses on your first three deposits, each worth a possible $1,000.

There are many other promos to get involved with, too. These include a unique 30% cryptocurrency reload offer and a potentially lucrative friend referral bonus. No matter how you earn your bonus credits, they can always be spent playing the best slots on BetOnline.

Security and Reputation

You must ensure you're not dealing with a rogue operator whenever real money gambling is involved. Generally speaking, the industry is clean and fair, but it only takes one bad apple, as they say. It's understandable if you don't trust online casinos because you had a terrible experience or read a horror story about someone else. But it's easy to find a secure gambling site in the USA.

First of all, make sure a respected international authority regulates the casino. That way, there's always someone to turn to in a dispute. Moreover, this guarantees that the operators are not criminals and that the site is run correctly. For instance, using the latest SSL security or following best practices around money management and social responsibility.

Fair Games

Closely related to the last point, checking that your casino offers honest games is essential. Not only is BetOnline regulated by the Panamanian government, but it also takes its games from trusted developers like BGaming and BetSoft.

These providers use independent third-party software testing labs to certify that their titles are randomly determined. They also verify other vital details, including the return to player rate. As such, you can be sure everything is fair, from the complete live dealer casino to the best slot game on BetOnline.

Customer Service

You're not very likely to encounter problems while enjoying the best slots on BetOnline. After all, it's a thoroughly modern site that uses the latest technology, including secure payment providers and a suite of contemporary games. However, technical issues that may be something other than the casino's fault can crop up.

When something goes wrong, especially if it involves money, you'll want immediate reassurance from a friendly and compassionate human being. Luckily, this casino offers professional round-the-clock support through its live chat widget. There's also the option to email and make a telephone call.

Deposits and Withdrawals

If you're going to try playing the best slots on BetOnline for real money, you'll need to fund your account. In turn, you'll want to see several different reliable, secure, and speedy deposit methods. This casino checks the essential boxes, with four major card providers, bank wires, and latencies available.

If you're lucky enough to win, you'll want to get your hands on your cash as quickly as possible. That's one area where BetOnline excels. If you use Bitcoin, Litecoin, Ethereum, or any other altcoins, you will get your withdrawal within two days. But this fee-free cash out will likely be received in less than a few hours.

Best BetOnline Alternatives Reviewed

Any of these fit the bill if you want to play the best casino games on BetOnline at a different site. Why? Let's find out now by closely examining these five US-friendly online casinos.

WildCasino - Huge $9,000 crypto welcome bonus

BetOnline is operated by the same owner as Wild Casino, which explains why there are so many similarities. Launched in 2017, this casino is also regulated by the government of Panama and boasts a similar selection of around 600 slots. With 16 cryptocurrency tokens among the two dozen payment methods, you're guaranteed instant withdrawals and secure deposits.

Games and Features

Most software developers providing BetOnline with games also supply Wild Casino. As such, there's a massive crossover in the game library. For instance, the live casinos of both brands are powered by Visionary iGaming, FreshDeck Studios, and Betgames. At the same time, the slots library features countless shared titles, including Merge Up, the best casino game on BetOnline.

What Else We Like

Should you encounter any issues playing the best slots on BetOnline, Wild Casino has your back.

SuperSlots - Around 600 video slots and full live dealer casino

Like Wild Casino, SuperSlots is another sister site of BetOnline. As such, you'll find a lot of similarities in the layout of the two casinos. Not to mention many of the same great casino slots, including all of the best slots on BetOnline. However, one point of difference is the welcome bonus, which is more prominent at SuperSlots and weighs in at $6,000.

Games and Features

If you're looking to play the best slots on BetOnline.ag at a different site, SuperSlots could be your best bet. The vast majority of the game library is identical, including the selection of table games, both live dealer and traditional. That means you'll find around 600 video slots across various entertaining themes backed up by dozens of table games, scratch cards, and more.

What Else We Like

Although SuperSlots is another casino emphasizing cryptocurrency, the Bitcoin welcome bonus is minor compared to Wild Casino's. That said, the 400% deposit match bonus worth up to $4,000 is still more significant than the signup incentive offered by BetOnline. Regarding the cryptocurrencies offered, you can choose from Bitcoin and 15 others, with fee-free, same-day withdrawals available too.


  • Generous $6,000 welcome package
  • Progressive slots and table games
  • Super fast withdrawals
  • No charges for crypto payments

HighRoller - Crypto casino with a wide variety of promos

This is one of the newest online casinos, having launched in 2023. HighRollerCasino.ag is smaller than our first two alternative sites, offering the best slots on BetOnline. However, there are still more than 550 slots in the game library. And better still, the welcome package is both flexible and generous.

Games and Features

Among the 550+ slots at HighRollerCasino.ag is a selection of titles with higher than average RTP rates. Although the casino is a little smaller, many of the highest-paying slots on BetOnline can also be found at this safe and secure alternative.

What Else We Like

Many different promotions are available at HighRollerCasino.ag, both for new and existing players. The welcome package is worth a total of $8,000.

Once you've spent it, there are countless other promos for regular players, including free spins and cashback rebates.


  • Flexible $8,000 welcome offer
  • $500 weekly cashback deal
  • More than 550 slots
  • 24/7 customer service team

Winport Casino - Secure gambling site with 24/7 customer support

It may have only launched in 2022, but WinPort Casino needs more time to impress. Already known as a secure casino without verification, the casino is licensed by Gaming Curaçao using the latest SSL encryption. It's another cryptocurrency casino, although NeoSurf vouchers and several other payment methods can be used.

Games and Features

There are approximately 500 games in the library, making it smaller than our other recommendations. However, many of the best slots on BetOnline highlighted on this page are available, plus a selection of other engaging titles. In addition, WinPort Casino also has one of the easiest-to-use mobile interfaces of any US online casino.

What Else We Like

In addition to hosting many of the best slots on BetOnline, including popular games like Bigger Cash Win, WinPort Casino is a potentially rewarding site. It all starts with the $7,000 welcome bonus. But there are dozens of free spin offers to choose from, too.


  • 500+ casino games
  • Impressive $7,000 welcome offer
  • Intuitive mobile site
  • Low minimum deposit of $10 via NeoSurf

Bovada - Quality sportsbook with the same range of BetOnline penny slots

One of the best-known sportsbooks in the US, offering thousands of competitively-priced lines every day, Bovada is a reputable brand. But did you know it also has an online casino? It may be a small size, with roughly 300 slots to experience. But there's a lot to love about this site.

Games and Features

Some of the best slots on BetOnline can be found in the Bovada catalog, our favorite of which is Beast Band. But plenty of live casinos and traditional table games are available at various betting limits.

What Else We Like

In truth, our other favorite feature, aside from the excellent slot games shared with BetOnline, is the sportsbook. No US bookmaker can match the comprehensive range of betting lines and player props. While it's fair to say the odds are some of the biggest in town.


  • $3,750 crypto welcome offer
  • Slots provided by reputable suppliers
  • Suitable for high-rollers and casual gamers alike
