The name STHLM GAMING is hardly familiar to the general gaming public. This is due to the fact that this software provider aims to engage the audience with quality rather than quantity of games. Also, this small studio has no ambitions to become an industry leader. Its owners are sure that they are sure to find their admirers. To do so, the company uses innovative mechanics, unique bonus features and advanced technology. For instance, its products use rare features such as Progressive Free Spins and Nudging Wilds. They are capable of leading players to big winnings.

The company is based in Stockholm, Sweden. For more than 5 years now (since 27 September 2016), the provider has been developing video slot models that meet the demands of the market as closely as possible. To make an impact, its experts have implemented and utilized a proprietary smart technology called "STHLM GAMING Smart All Devices". The company's games are integrated into online casinos via Relax Gaming's Silver Bullet platform. Thanks to this partnership, its products are familiar to customers at 52 online casinos.

None of this would be possible if it weren't for the studio's team. Professionals, enthusiasts, visionaries, people committed to providing consumers with a unique experience - this is all about the company's specialists. Shoulder to shoulder, this team of 10 employees works for us every day.

How I chose the best STHLM Gaming casinos

Before you play slots from STHLM GAMING, think about the reliability of the operator. I daresay, every player at least once faced with the inappropriate treatment of himself and his participation in the life of the casino by the administration. Unfortunately, the number of such sites is increasing every year. Moreover, the actions of inherently fraudulent casinos are getting more sophisticated. The result - at a glance it's impossible to tell whether you can trust a particular institution. If you don't want to fall for their tricks, before placing bets, consider the website in terms of such criteria as:

  • The validity of the license. You, like me, can easily check it yourself in the basement of the homepage. Clicking on the appropriate regulator icon will take you to a special page. Examine it carefully for errors, validity period, type of games allowed to the licensee

  • The originality of the software can be checked using the server of the company with which they cooperate. In the case of this developer, the games are hosted by Relax Gaming

  • A good reputation of the gambling establishment. An operator with a positive reputation will not risk it, which means the chances of cheating are extremely low

  • Efficient customer service. Even such a seemingly small detail is an important part of a good site. Players should be able to solve all their questions and problems related to the gameplay on the spot. The staff, in turn, strive to help them in any way they can

  • The ease of document verification in the KYC procedure. The reason for this is simple - it is not in the interest of the company to overwhelm the customer with demands, because then they would lose interest in the site. At the same time, the absence of this procedure is also a reason to avoid a casino

  • A wide range of financial options is one of the aspects that speak for the reliability of the operator. A licensed operator has the possibility to connect many payment systems. If not, the provider is not interested in a long-term relationship with users

  • A reliable casino is happy to encourage its customers with numerous promotions and bonuses (cashback, cash bonuses, races, tournaments, free spins), including as part of the current VIP program

  • An honest operator does not seek to retain a player's winnings. During the waiting period, the other may lose everything he has been credited with. On the contrary, the administration offers quick withdrawals and large limits

  • A good operator's gaming library has the financial and partnership capacity to host more than just video slots.

You may think choosing a reliable online casino is a daunting task. If you have the understanding to check it out, STHLM GAMING games will bring you excitement and fun.

The company's portfolio includes 5-reel slot machines. None of the products on offer have a progressive jackpot feature. This comes as no surprise. This is the trend with all young providers and STHLM GAMING is no exception. Instead, the studio develops slot machines with high volatility and high betting returns, as well as interesting mechanics.

The company's products include 10, 20 and 243 fixed paylines. As for the latter, these games use the Reel Set change feature. It allows the bonus round mechanics to change to the Megaways feature.

Most games have a minimum bet of 0.25 coins, but it is also possible to start betting at 0.1 coins. The minimum bet can go to a maximum of 100 coins. To fix it, use the game panel and choose the size that suits you in the settings. You can then press the '+' located above the spin button and also fix the automatic spinning of the reels up to 100 units.

The flaw in the slots is that the provider offers too simple an interface, without the extra features of quick play, one-click maximum bet selection. Everything is pretty standard, just like in the older models. However, only experienced players might have such an opinion, while for beginners this is a great way to understand the specifics of the slots setup.


Each slot machine operates on an RNG basis. It is responsible for the random symbols that are formed into winning combinations. At the same time, not every slot can be 'generous giving back'. In order to understand what you can count on in a particular game, the providers put a theoretical rate of return on bets in them. The most profitable from this point of view is RTP above 97%. It is not as common as players would like it to be.

The company's products have a decent RTP. The lowest RTP is set only in the Stack of Riches slot. It is a whopping 95.91%. The Boost It slot, on the other hand, has the highest RTP at 97%. So it is clear that the average RTP of STHLM slots is around 96,7%.

Best 5 STHLM GAMING Slots of All Time

In terms of RTP, slot machines lead the provider's portfolio:

  • Boost It with an RTP of 97%, the maximum winnings are an amount that is 810,000 times the bet

  • Van Gogh has an RTP of 96.83% and maximum winnings of x5,000

  • Sunset has an RTP of 96.58% and a maximum winning ability of x97,400

  • Icarus Wild has the ability to return 96.54% of the wager size and give a maximum winning of x16,864 bets

  • Casino on The House with an RTP of 96.5% and maximum winnings of x7,433.


The company entered the market with its first video slot model in 2017. During the following year, the next 3 machines were released, in 2019 the portfolio was expanded by 4 more games, and in 2020 only one slot was released. Such figures are, of course, frustrating not only for the users but also for the developers themselves. The reason lies in the fact that they have failed to meet their roadmap. This in turn slows down the provider's development and ability to compete with similar companies.

Fairness of STHLM GAMING Slots

The company's RNG products have been tested and certified by eCogra, today's leading testing laboratory. Successfully completed tests assure consumers that the stated parameters are consistent with the actual parameters and that they are honest.

STHLM GAMING slots features

It can hardly be argued that the company has had time to reach its full potential when it comes to the presence of bonus options. We can only settle for such bonus features:

  • Wild, Sticky Wild, Random Wilds/ Additional Wilds (Perfect Catch)

  • Multiplier (Ricky Riches)

  • Scatter (The Golden Chase)

  • Free Spins, Free Spins Multiplier, Guaranteed Wild in Free Spins (Van Gogh)

  • Feature: Substitution symbol (Stacks of Riches)

  • Avalanche/ Cascading wins (Sunset)

  • Reelset Changing (Sunset)

  • Additional Free Spins (The Golden Chase)

  • Respins (Sunset)

  • Stack (Ricky Riches)

  • Sticky Wild (Ricky Riches).

Can I play STHLM GAMING games on mobile devices?

Yes, of course! STHLM GAMING uses the HTML5 coding language, popular in recent years, to create your next game. Thanks to it, you can move freely between desktop and mobile devices with Android and iOS. There's no need to worry about the quality of the software because the technology adapts the slots equally well to any smartphone or tablet screen size.

Sound and Graphics of STHLM GAMING slots

The provider's slot machines delight players with their detailed graphics, elaborate animations and perfectly matched music. This makes it easy for consumers to immerse themselves in the theme of the chosen slot and get the most out of the gaming experience.


Final thoughts

STHLM GAMING is a small studio with no pretensions to leadership in the industry. At the same time, they focus on the quality of their products, their mechanics and bonus features. Unfortunately, in terms of the number of video slots in their portfolio, the company is far behind even younger providers. Seeing its potential, we do expect a significant jump upwards in 2022.
