Studio History and Timeline
STHLM Gaming entered the industry with a clear goal: to create design-led slots that balance simplicity with mechanical depth. Founded in Stockholm, the studio quickly gained recognition for its “smart simplicity” philosophy — games that are easy to learn but rich in features.
Instead of chasing volume, STHLM focused on carefully crafted releases distributed through aggregator platforms. This boutique approach, combined with a Scandinavian design flair, allowed the brand to establish a loyal following in regulated European markets.
Key Milestones
- 2016 – Studio founded in Stockholm, Sweden, aiming to redefine slots with “smart simplicity.”
- 2017–2019 – First wave of titles, such as Stacks of Riches, gained traction across European aggregator platforms.
- 2021 – Became part of Spiffbet, expanding distribution reach while keeping creative independence.
- 2022 – Wider rollout into regulated European markets, with emphasis on UKGC compliance.
- 2023 – Acquisition by Million Games following Spiffbet’s asset sale, giving STHLM more scalable resources.
- Present – Continues to develop innovative titles, ensuring every release aligns with fairness and responsible-gaming expectations.
Through these changes, STHLM Gaming has shown adaptability while staying true to its design identity. Ownership transitions strengthened resources without altering its core philosophy: lightweight games, fair RNG outcomes, and a player-first focus.
📦 Important Reminder: Ownership changes and distribution partnerships do not affect fairness. Every STHLM title is tested and certified under UKGC-approved RNG standards.
Slot Mechanics and Gameplay Style
STHLM Gaming’s portfolio is designed for clarity and approachability, appealing to both casual players and experienced slot fans. Many games use medium volatility profiles, striking a balance between steady payouts and engaging features.
- Crisp Visuals and Thematic Design
Bold, stylized graphics give STHLM slots an instantly recognisable identity. Slot themes range from reimagined fruit machines to art-inspired designs like Van Gogh.
- Stacked Symbols & Nudging Wilds
These mechanics, showcased in Stacks of Riches, increase win potential and session excitement without altering fairness.
- Expanding Reels and Free Spins
Slots like Sunset use expanding reels and bonus spins to add variety while keeping gameplay transparent and straightforward.
- Random Multipliers
In titles such as Boost It, multipliers are applied randomly in the base game, creating surprise moments of higher returns.
- Bonus Wheels and Thematic Extras
Games like Casino On The House incorporate wheel-based bonuses and stacked icons, staying true to classic slot hall experiences.
📦 Important Note: Features such as stacked wilds, multipliers, or expanding reels affect gameplay feel but never the underlying randomness. Outcomes are always governed by UKGC-certified RNG systems.
At this point, if you’re exploring on a casino mobile app, STHLM titles are lightweight and optimised for quick loading across devices. This makes them suitable for short, casual sessions with full access to safer-play tools.
📢 Always responsibly play by setting limits and making use of operator tools before starting.
Example Slot – Casino On The House
One of STHLM Gaming’s most ambitious titles, Casino On The House combines a classic casino theme with feature-rich mechanics that showcase the studio’s creativity. It’s a standout release for players who enjoy traditional aesthetics but want more layered gameplay.
Theme & Design
The slot is styled after a classic casino floor, with rich colours and iconic symbols like chips, dice, and cards. Visuals are bold yet lightweight, ensuring smooth performance on desktop and mobile app platforms.
Core Mechanics
- Bonus Wheel – Spins randomly trigger a feature-packed wheel offering free spins, multipliers, or instant prizes.
- Stacked Icons – High-value symbols can land in stacks, boosting win potential.
- Feature Variety – Multiple modifiers add unpredictability, keeping sessions lively.
Volatility & Pacing
Casino On The House is a high-volatility slot, appealing to players who enjoy risk/reward balance and the chance at larger but less frequent payouts. This contrasts with STHLM’s medium-volatility titles, offering diversity in its catalogue.
Why It Matters
This slot exemplifies STHLM Gaming’s ability to merge classic themes with innovative mechanics. While the design feels familiar, its layered features make it stand out in boutique portfolios, reinforcing the studio’s commitment to “smart simplicity.”
📦 Fairness Reminder: Features like bonus wheels and stacked symbols influence entertainment value but not the randomness of outcomes. Results remain fully RNG-certified under UKGC rules.
