STHLM Gaming Casinos — Games, Fairness and Where to Play
STHLM Gaming is a Stockholm-based video slot developer founded in 2016, operating under licenses from the UK Gambling Commission, the Malta Gaming Authority and Sweden's Swedish Gambling Authority. Its games reach players through a distribution partnership with Relax Gaming struck in October 2018, and since August 2023 the studio has been part of the Million Games group.
Within our catalogue, STHLM Gaming ranks 338th of 511 slot providers, ordered by the number of casinos carrying that provider's games. That places it well below Hacksaw, which appears at 122 casinos in the same ranking, and closer to smaller studios such as Everest, carried by 6 casinos, Zitro or Spinza, each carried by 3 casinos, or Jili, carried by just 1.
Who Is STHLM Gaming
STHLM Gaming was founded in 2016 in Stockholm, Sweden, by founder and CEO Jonas Byström, with an early team of roughly 10-50 people. Byström left the CEO role in 2020 to join ELK Studios, a move that predates two later ownership changes at the studio itself.
Spiffbet acquired STHLM Gaming in 2019, and Million Games AB acquired the studio in August 2023. At the time of that second acquisition, STHLM Gaming's own portfolio stood at roughly 10 or more titles; the wider catalogue tracked for the brand today runs to 21 games. The studio lists the United Kingdom, Sweden, Malta, Ireland and Italy as its areas served.
STHLM Gaming Games and Signature Mechanics
STHLM Gaming builds video slots exclusively — there is no live-dealer or table-game line under the brand in the material tracked for this studio. Its first release reached the market in October 2017, a year after the studio's founding, and the catalogue grew from there to the 21 titles now associated with the brand.
The studio's proprietary technology, marketed as STHLM Gaming Smart All Devices, is built to adapt a slot's layout across desktop, tablet and mobile screens from a single build rather than a separate mobile version. This is a platform-level feature rather than a per-game mechanic, and it applies across the studio's catalogue rather than to any single title.
STHLM Gaming RTP, Volatility and Fairness
STHLM Gaming reports an average RTP near 96% across its slot catalogue. That figure is theoretical: it describes the return expected over a very large number of spins, not the outcome of any single session, and actual results on any given day can sit well above or below it.
STHLM Gaming's slots operate under licenses from the UK Gambling Commission, the Malta Gaming Authority and Sweden's Swedish Gambling Authority. All three regulators require certified random number generation as a condition of licensing, which is the mechanism that keeps outcomes independent of previous spins or a player's staking pattern.
STHLM Gaming's games have been distributed through Relax Gaming's network since October 2018, which is why many operators list the studio's titles alongside Relax Gaming's own catalogue rather than as a separate integration.
Where to Play STHLM Gaming Games
A shortlist of casinos carrying STHLM Gaming games is presented above this article. Among them, RocketPlay operates under a Curaçao license, while Rooster Bet Casino and Lucky7even both hold licenses issued by the Tobique Gaming Commission. Across these operators, there are 49 active bonuses: wagering min 1x, avg 27x (41 bonuses), 22 include free spins, match up to 425%. Deposit methods across this selection commonly include Neteller casinos alongside Jeton and card options, and a broader look at operator standards is available through the trusted casinos directory.
- Provider availability — confirm STHLM Gaming titles are actually listed in the casino's lobby, not only in a general provider catalogue.
- License — check whether the operator holds a Curaçao or Tobique license, since dispute handling and payout rules differ between them.
- Region — STHLM Gaming lists the UK, Sweden, Malta, Ireland and Italy as areas served, so availability can vary by country.
- Demo mode — test a title's mechanics and paytable in free play before staking real funds.
Common Misconceptions About STHLM Gaming Slots
- "A slot is running hot or cold" — outcomes are generated independently spin to spin by a certified random number generator; there is no streak mechanism to detect.
- "96% RTP means 96% of any given session returns as winnings" — the figure is a long-run average across a very large number of spins, not a per-session guarantee.
- "A 21-game catalogue means lower-quality games" — portfolio size reflects the studio's release pace since its 2017 debut, not the audit standard applied to any single title.
- "Million Games and STHLM Gaming are separate, competing brands" — Million Games has owned STHLM Gaming since the August 2023 acquisition, so the two are not independent competitors.
Verdict on STHLM Gaming
"STHLM Gaming is a small, licensed video-slot catalogue built for players who want a tightly regulated studio rather than a sprawling one."
STHLM Gaming suits players who value a studio with named regulators behind it — the UK Gambling Commission, the Malta Gaming Authority and Sweden's Swedish Gambling Authority — over one with the largest possible library. Its 21-title catalogue and roughly 96% average RTP are modest by industry scale, and its position of 338th among 511 tracked providers by casino coverage reflects that. Players chasing a wide selection of titles at every stop may find the footprint thin; players prioritising a licensed, audited slot line over sheer volume have a clearer case for it.
Gambling is entertainment, not a way to make money or fix finances. Set deposit and time limits, take regular breaks, and use self-exclusion tools if play stops feeling like fun. Licensed operators provide these tools — using them is a sign of control, not weakness. Learn more on Responsible Gambling →
