STHLM is a Swedish studio that makes casino-style slot machines. They make their games in HTML5, which means they are compatible with any platform, and can be played on smartphones or computers. The company was founded in 2016 by three friends who had an idea for a new type of gambling machine, but couldn't find the right developer to help them execute it.

There are currently about a hundred online casino software studios in the industry. The most difficult ones are those that have emerged recently. They have to look for new solutions that will allow them to break into the market loudly and with dignity. Moreover, their games should have some features that are attractive to casino customers and operators alike.

This studio has made a bet on player benefits. The average RTP of the portfolio is 96.4%. This is considered a good indicator. Why do I pay attention to this indicator? It's simple. It is very important to know what the average value of a particular developer is. In this way, we can understand whose interests he supports to a greater extent. In this case, we can state that it is the players, not the operators' income, that are important for the studio in the first place.

Best 7 STHLM Slots

STHLM Gaming's portfolio is extremely limited. As such, the company's list of top slot models includes 75% of its entire library. That said, they all include a good return on their bets. See for yourself:

  • Boost It is a slot machine with a very good betting return of 97%. This model has a maximum winning of 810,000 coins

  • Van Gogh is an art-themed slot with an RTP of 96.83% and a maximum multiplier of x5,000

  • Sunset, an unusual road trip-themed slot with an RTP of 96.58% and a maximum win of 97,400 coins

  • Icarus Wilds, a slot based on Greek mythology with an RTP of 96.54% and a maximum multiplier of x16,864

  • Casino On the House is a slot that keeps the spirit of the gambling establishment alive with 96.5% and a maximum multiplier of x7,433

  • Perfect Catch is an underwater-themed comedy slot with an RTP of 96.32% and a maximum multiplier of x2,787

  • The Golden Chase is a 'precious' slot with an equally precious RTP of 96.27% and a maximum multiplier of x6,699.

STHLM Slots Features

This studio's game library does not boast diversity. However, to give it a personality, the provider has included several features. These can yield larger payouts compared to games without any features. It cannot yet be said that the provider has put the most effort into its products, but its potential is clearly visible.

In the studio's games, features lead to cash wins:

  • Random Wilds, Multiplier, Substitutional symbol (Boost It)

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

  • Avalanche, Changing reelset, (Sunset)

  • Scatter, Sticky Wild (Icarus Wilds)

  • Free Spins Mode Choosing, Symbol collection, Expanding symbol (Casino On the House)

  • Multiplier, Wild (Icarus Wilds)

  • Additional Free Spins, Respins (The Golden Chase).


STHLM Gaming's software is interesting, but it's not in crazy demand among players. That's because their portfolio is too small to conquer the markets on a "come-saw-win" basis. In addition, since its inception to date, the studio has not released a single slot with a progressive jackpot. This factor also contributes to its limited popularity.

The provider's gaming content includes slot machines with a 53 and 54 grid. What the studio emphasises most is not the standard paylines, but the so-called winning ways. This is evidenced by the frequent use of mechanics with 243 ways to win. Of the standard paylines, slots with 10 and 20 paylines are offered.

When you play in a model where payouts are made by way of winnings, you will have to bet directly on the spin. The betting range in this case will range from 0.25 EUR to 120 EUR. In games with paylines, the betting variation is 0.1 EUR to 100 EUR. In this variation, your total bet will be much higher than in games with ways to win.

The provider has refused to include unnecessary buttons in its designs. The slot machines will be available to you:

  • Bet. To change the bet amount, click on this button and select the desired bet amount from the following

  • Turbo spin button to save time by instantly spinning the reels

  • Autoplay - this button allows you to distract yourself while the reels spin by themselves.

As you can see, the studio has tried to make life as easy as possible for players. The simplicity of the interface makes it easy for even beginners to get to grips with the settings.

STHLM Slots List

STHLM Gaming was founded in 2016 in Stockholm, Sweden. During that time, the studio has partnered with Relax Gaming, the world's leading software developer. Based on this partnership, STHLM games are hosted by Relax Gaming and therefore become available in many markets.

However, even this lucrative partnership did not give this studio ambition. In over 5 years of industry presence, it has released just 9 titles. It turns out that their average rate is 2 games a year. This is an unsatisfactory rate even for a micro-company. Moreover, the last release was way back in 2020. It's unknown what happened to this game studio, but according to their roadmap, all plans have been completely disrupted. So, they were ready to release 5-6 models in 2019 and 8-9 models in 2020. This suggests that we shouldn't expect anything special from the studio in the coming years.

Fairness of STHLM Slots

STHLM Gaming is a company established under the laws of Sweden. This jurisdiction has given us such a world-renowned provider as NetEnt. Unfortunately, I could not find any legal document that proves that the provider's software is licensed and certified. However, that's not to say that the studio's RNG isn't up to standard. The company partners with Relax Gaming, a leading software development company. Under their arrangement, the games of the provider in question are hosted on Relax Gaming's platform. The latter company, in turn, will not use software that does not meet security, fairness requirements. This allows us to say that the studio does carry out research into the fairness of RNG, but does not report it on its website.

Mobile STHLM Slots

Smartphones are an important part of everyday life for most of the world's population. Mobile gaming is an important part of any player's life. If you combine the two, you get mobile slots. Thanks to them, even a small break at work becomes a fun activity. Realizing the need to entertain users 24/7, this studio has used HTML5. It allows STHLM Gaming games to play on any device of any operating system - PC, laptop, smartphone, tablet.

STHLM Slots Sound and Graphics

The studio looks for new themes and solutions for its portfolio. Take the Van Gogh slot, for example. It is dedicated to the work of the 19th-century Dutch painter of the same name. Despite the fact that there is no three-dimensional graphics in this machine, it is immediately clear that it would be superfluous. Perfect Catch, on the other hand, already has this modern technology. It brings river creatures to life - frogs, fish and even a tattered shoe. Each game features a soundtrack that plays as you play. It complements the studio's automata very well.
