The Top Five STHLMGAMING Online Casinos

Based on our expert reviewers’ investigations, we have put together this list of the five most impressive gambling sites offering the games from STHLMGAMING. These operators, of course, offer titles from the developer’s portfolio, but they stand out in other ways, too.

We’ve outlined some highlights from what makes these STHLMGAMING casinos so remarkable in the table below, which we will further explain as the article continues. Here, you can choose any of these five licensed websites and know they each provide a safe and entertaining experience.

As you can already see, there are some rather large differences between our top five STHLMGAMING casino sites. The differences go even deeper, so we’ll help you understand which one is the best for you based on the various personal preferences.

Regardless of which operator you choose, you’ll be pleased to learn that the registration process is always easy. You’ll need to provide a bit of personal information such as your date of birth, email and address, then verify your identity. Start by following these three steps:


Select the STHLMGAMING casino site that best matches your requirements for a great online gambling experience.

Register Your Account for Free

Follow the simple instructions on the website to create your own player account, using accurate personal information.

Claim Your Bonus

Make your first deposit to claim the new player welcome bonus offer, then enjoy the STHLMGAMING.

We understand that there are a lot of different things to look out for when deciding which STHLMGAMING casino is the right one for you. This involves comparing many factors across multiple sites, but don’t fret – we’ve done it for you. Read on to see what we look for.

The Important Comparison Criteria

As mentioned, many of our judging criteria for finding the best STHLMGAMING online casinos involves the safety features. We recommend sticking to operators that hold a licence from your local jurisdiction’s online gaming authority.

If there is no such thing, look for one that meets the UK casino standard and hold an operating licence from the Gambling Commission. Many others also could hold a licence from the Malta Gaming Authority, another reputable casino licensing authority.

Although this guide to the best STHLMGAMING casinos will only include operators that stock the games from the Swedish developer, that isn’t enough for them to earn our recommendation. As you’ll see, the provider has a small selection of games, so it is on the casino to ensure they have cultivated a holistic portfolio from other developers.

There must be a good variety of options across slots and roulette games, as well as the most popular card games like blackjack. Of course, none of it is worth anything if there isn’t a user friendly website design supporting all the other features.

Finding Good Bonuses

One of the biggest differentiators between online casinos is the type of promotions that they offer. Any casino bonus will be designed to lure players in and keep them gambling, presenting a variety of different freebies, including deposit match deals for extra cash or free spins.

It is of the utmost importance that you check the wagering conditions before claiming any bonus deal. The wagering conditions refer to how many times you must bet the value of the bonus amount before you can claim, or withdraw, any winnings.

Each bonus will have a different set of rules, which will also include a deadline within which these requirements must be fulfilled. This could be anywhere from 24 hours to 90 days, depending on which casino you elect to play, and which type of bonus.

Some no deposit bonus offers will often consist of free spins on selected slots. This means that although you are playing at a STHLMGAMING casino, you may not be able to play the developer’s games, as not all titles contribute towards the wagering conditions.

Most often, these deals are only available to new players upon signing up for an account and are triggered when making the first deposit. However, some payment methods are excluded from being used to claim welcome bonuses, so check the fine print before losing your opportunity to bag a bonus.

How to Find the Best Free Spins Deals

One of the most popular and increasingly common types of welcome deal are free spins. Some are presented when players sign up for a new account, giving you the opportunity to try out select titles before making a deposit. Of course, these STHLMGAMING casino bonus offers will almost always come attached with wagering conditions, as mentioned above.

STHLMGAMING Games: The Entire Catalogue Breakdown

As one of the newcomers to the online casino gaming development industry, it comes as no surprise that the STHLMGAMING portfolio of games is still rather small. The developer only has seven slot games that are currently available on casinos worldwide.

However, what you’ll find out about this company that what it lacks in quantity, it makes up for in quality. As such, it joins a collection of software developers worth following.

The STHLMGAMING Slots Selection

As mentioned, this developer has produced seven slot games in its short time as a software developer. Across this collection, there is a surprisingly large variety of themes and gameplay mechanics available, with each title offering something different.

This is noteworthy as many other providers often develop one core game, then layer it with a different theme, which means that the gameplay is exactly the same, but with different pictures. Not the case with the STHLMGAMING casino games – each game has a unique return to player (RTP) rate and different bonus features.

By clicking through on the link above, you’ll be taken to one of our recommended casinos to start playing right away. There, you’ll find a collection of the developer’s games as part of a catalogue of hundreds of slots, blackjack and table games to enjoy. If you’re still not convinced, why not check out the ReelPlay online casinos instead.

Smooth Animations

The time and care that has gone into the development of each of the STHLMGAMING slots is evident by watching the games’ animations. Each click of the reel shows how they spin with a wind-up first, replacing the once-familiar clunky movements of classic slots with the smooth, visually pleasing rolls. Upon finding a winning combination, the symbols light up and dance, moving to the motions of the celebratory designs and animations.

Gorgeous Graphics

Regardless of the theme of the slot in question, the aesthetics of each title is superb. Each title has been given the full treatment, from the symbols, to the background images and even the rule pages. The symbols are, of course, the highlight of the visual aspects, with each one carefully and lovingly designed, a pleasure to watch and raising the standards from the old cherries and 7s.

To give you a better idea of the quality, we’ve got a demo version of one STHLMGAMING slot available for you to try out for free. Have a look and get a first-hand understanding of the fantastic visual features.

Max £5/spin or £0.50/line or £50/round (live casino). 30 days expiry. T&C's Apply. Please gamble responsibly http://www.begambleaware.org/

The company’s latest development is a pink, somewhat 1950s themed title called “Casino On The House”. It brings vibes reminiscent of the classic musical “Grease”, though you won’t find any similar characters to Danny or Sandy. Instead, you’ll find free spins bonus and a Super Free Spins bonus that trigger frequently, adding excitement and panache. More titles are planned for release soon, so keep an eye on STHLMGAMING news updates.

Currently Unavailable: STHLMGAMING Jackpot Games

One incredibly popular type of slot game for players worldwide are those with progressive jackpots, however at the time of writing, there were none attached to any titles from STHLMGAMING. Instead, you can check out the Microgaming jackpots.

Currently Unavailable: Card and Table Games from STHLMGAMING

As a specialist in slot game development, there are not currently any card and table games of any kind from this Swedish developer. However, all of the STHLMGAMING online casinos recommended above offer a selection of blackjack, roulette, baccarat, and poker titles from other providers.

There are lots of options when it comes to the other types of games that are available at the casinos, so no matter what type of gambling you like to do, you’ll be covered. For example, a common pairing with slots are scratch cards, which share the simplicity and chance of the reels.

Additionally, you’ll also find a fantastic live dealer suite of games that cover all of these gameplay types. Live games make a great online casino, as they are the closest thing to the atmosphere of a real gambling house without going outside.

Player Rates – Incredible Statistics

Return to Player (RTP) rates of online casino games are a theoretical set of statistics that describes the long-term losses that a player can expect. The rate, described as a percentage, should be as close to 100 as possible, in order to have minimal losses from the player.

The average across the industry is between 92 – 96%, but six out of the seven slots have an RTP above 96%. The only one that is under 96% is Stacks of Riches, which still comes in at 95.91%. Therefore, this developer’s slots have an average RTP of 96.48%.


The important thing to keep in mind is that these statistics are certified by third-party testing authorities that run the software through hundreds of thousands of simulations. This is in no way reflective of the general win-loss ratio as can be expected over the short term.

Other Leading Software Providers

As mentioned, there would be no online casino that could survive from purely offering the seven titles from this developer, therefore they will round out their portfolios with games from other providers. Cultivating a strong casino platform is about collecting a good mix of titles from top firms.

There are dozens of competing developers, and you will likely see games from the likes of Relax Gaming at the best STHLMGAMING casino sites, as they share a distribution platform. You’ll also likely find titles from industry leaders Play’n GO and Netent.

Competitor Software Companies

Some gameplay types will be at all STHLMGAMING online casinos. For example, there will be blackjack and casino poker variants, and the long-standing video poker games. Alongside these popular table games, a great site will likely include Mega Moolah, the world’s favorite progressive jackpot slot. It’s also very likely you’ll find Starburst, an incredibly popular title from NetEnt.

Mobile: Smart Devices

Thanks to the fact that the STHLMGAMING online casino titles have only begun development in the last few years, they have the benefit of being made using the latest technology. As such, the company promotes its “STHLMGAMING Smart All Devices” trademark, a promise that its games will work on any device in any orientation.

Therefore, it is up to the STHLMGAMING casino sites to offer downloadable casino apps or mobile-optimised websites. Of course, these sites wouldn’t gain our recommendation without this feature, as mobile gaming is the most popular way to access online casino games these days.

The operator in the table above is our pick as the best STHLMGAMING casino app, as it not only offers the largest number of the developer’s games, but also has a great all-round offer. The app is easy to use and free to download, and you can simply log in using the same details as on the desktop version.

Reliable STHLMGAMING Casino Features

Considering that the safety of online gamblers is so important, we’ve put together some helpful information about how to identify the which sites, including STHLMGAMING casino sites, are reliable. As mentioned earlier, holding a license from an approved authority is the first thing to look for.

After that, we recommend checking which third-party agency has tested the games for fairness. A name you will frequently see is eCOGRA, which, alongside iTechLabs, is one of the biggest firms that certify game RTPs and Random Number Generators (RNG).

Casino Licenses Testing Encryption Responsible Gambling
Casumo UKGC, MGA 128-bit GamCare, GamStop
Mr Green UKGC, MGA 128-bit Gamblers Anonymous, GamCare
Betsafe UKGC, MGA, Spielinspektionen 128-bit GamCare, GamStop
LeoVegas UKGC, MGA, Spillemyndigheden 128-bit GamCare, GamStop
Unibet UKGC, MGA 128-bit GamCare, GambleAware

On top of these features, it’s important to check the types of partnerships with responsible gambling organizations are in place. The dangers of addictive gambling are ever-present, so it is crucial to gamble at safe sites that do not promote irresponsible habits.

Making PayPal and Other Payments at STHLMGAMING Sites

Once you have decided on which of the best STHLMGAMING casinos is the right one for you, it’s time to make a transfer of real money to your casino wallet, so that you can start enjoying the games. However, not all operators offer the same payment methods, so it could be wise to check that your preferred option is available before signing up.

All of our recommended STHLMGAMING sites will have a selection of credit card, debit card and eWallet options, but these break down into rather a few variables. For example, many gamblers prefer to use eWallets like PayPal, as they offer additional security, safety and simplicity.

The Best Casinos that Accept PayPal

Unfortunately, PayPal is not available in all online casinos, particularly absent for US gambling and Canadian casino payments. Instead, other eWallets like Skrill and Neteller take its place, and you can currently always rely on credit card payments to be processed painlessly.

Help and Customer Support at STHLMGAMING Sites

Talking to customer service representatives should always be a simple process, with lots of contact methods available. The standard expectation is for a STHLMGAMING casino site to offer a phone hotline, live chat and email address at the very least.

Many operators will also offer a comprehensive set of FAQs or a Help section that you can turn to first, before you need to reach out to an actual person. All of our recommended operators will provide service in English, so if you prefer a different language then check what is available.

Important STHLMGAMING Company Information

Sweden-based firm, STHLMGAMING, started in 2016 and released its first game, Stacks of Riches, in October 2017. The company is headed by Jonas Byström, working together with André Nylander to bring decades of experience to the new endeavour. Fellow Swedish firm, Spiffbet, acquired STHLMGAMING in July 2019, further spreading the company’s games over their home country.

The firm signed a partnership with Relax Gaming in 2018 to provide the STHLMGAMING titles on the Silver Bullet platform, which far extended the Swedish company’s reach. Now, the company has seven slots under its belt, and plans to release another “8-9 games” in 2020.

One of the main selling points of the company’s products is its mobile approach. More than just “mobile first”, the company claims to build its games in a system that adapts to any screen, regardless of the device itself.

Though the collection of STHLMGAMING titles is still small, the quality of the games, their graphics and their soundtracks are unforgettable.

To our top 5!

The company has not been around long, but it has arguably already made a mark on the online casino industry thanks to the high quality of its games. We expect this company to continue to add more enticing and exciting games to its portfolio and become a big competitor to the leading firms.

STHLMGAMING Casino Partnerships and Licencing Agreements

No online casino can call itself a STHLMGAMING online casino unless it holds a licencing agreement with the software developer. Much like how television stations can only show programs with which they hold the rights to do so, so too can online casinos only offer games that they hold a licence for.

These licenses are unique between each operator and the developer, which explains why not all of the games, or the same selections of games are available on each casino. This two-way system does a lot to ensure that the player’s safety comes first, as no rogue operator can sneakily offer fake brands or untrusted games.

Stay Up To Date

As mentioned, this company is new to the scene and has hit the ground running. It aims to release a handful of games each year, which we will follow, and our team of journalists will cover on our news site.

Some of the latest STHLMGAMING news

We will also add other interesting news about competitor software developers so you can see the latest news and compare the different providers. In line with that, we constantly update all of our pages so if you’re looking for the newest online casinos then check back frequently for new STHLMGAMING casino.
