The expected value behind Sthlm Gaming

Sthlm Gaming is a Stockholm-born slot developer founded in 2016, formally known as Sthlm Gaming Sweden AB. I see it as a narrow-output studio with experienced personnel, not a volume factory. The debut release was Stacks of Riches in 2017, followed by more recognisable releases such as Van Gogh, Sunset and Boost It.

Ownership history matters for continuity. Spiffbet acquired the studio in 2019, then sold the game development division including Sthlm Gaming and Rhino Gaming to Million Games in 2023. That explains the uneven release cadence. My overall read is mathematically interesting but operationally fragmented, with a small catalogue carrying more variance than brand recognition.

EV broken down across Sthlm Gaming

Mathematically, Stacks of Riches at 95.91% RTP gives the house edge works out to roughly 4.09%, while Sunset at 96.58% leaves about 3.42%. Icarus Wilds sits at 96.54%, so the theoretical expected value sits below break-even. This is a rough estimate, but a telling one, because the better titles still price in a clear casino margin.

I would model the studio through EV decomposed segment by segment: base-game return, free spins return and tail contribution from rare maximum-win events. A Monte Carlo run across ten thousand spins can still misread the top end, because weighting the rare outcomes correctly is the hard part. Standard deviation expressed per unit stake will dominate short sessions; that is the residual variance once the RTP is stripped out.

Signature mechanics

Features across the catalogue are mostly Wild-led. Icarus Wilds uses Nudging, Locked and Multiplier Wilds, while Sunset expands from 243 ways to 1,024 ways in free spins. Boost It adds a horizontal Booster Reel with Random Wilds, Wild Reels, Symbol Multipliers and Win Multipliers, making each feature's contribution to overall EV easier to separate.

Personally, I prefer Van Gogh for EV diagnostics because its Colour Splash collection changes expected value conditional on the trigger firing. The stationarity assumption is debatable here, since stored colours alter the bonus state before free spins begin. That can create a common cognitive bias among players: visible progress feels like added value, even when the theoretical margin reconstructed from the paytable remains negative.

Catalogue by category

Portfolio depth is limited, but the named games cover several mathematical shapes. Stacks of Riches is the simpler 10-payline fruit-style opener with 600x potential. Van Gogh is the art-led 20-line game with a 10,000x ceiling. Sunset is the 243-ways road-slot with 1,024-way free spins, while Boost It is the cleaner multiplier experiment.

Later and planned releases broadened the risk profile. Perfect Catch adds fish multipliers, extra wins and up to 30 free spins. The Golden Chase targets 6,500x with feature unlocking. On the House was positioned as highly volatile, and Boost It 2 extends an existing concept. I put Icarus Wilds highest for maximum-win hunting, but the base game can drag.

The regulatory side

Distribution ran through Relax Gaming's Silver Bullet platform after the 2018 partnership, which improved access to regulated casino lobbies. Sthlm Gaming also built around Smart All Devices and HTML5, with support for common currencies and more than 20 European languages. I do not treat those items as EV-positive; they affect access, not payout.

Licensing visibility is thinner than I would like. The studio has a Swedish corporate base and certified fair-play positioning, but a direct UKGC or MGA studio licence is not clearly established in the profile data. For UK players, the safer EV adjusted for opportunity cost is to use regulated venues where game certification, responsible gambling controls and payout audit trails are present.
