About Just Slots
The name is a statement of intent. No table games, no live casino, no crash titles or instant wins. Just Slots. Malta-based, founded in 2024, and already operating with a clarity of purpose that most studios take years to develop.
Led by CEO Thomas Groven and CCO Christine Parkhill, the studio was built by a team of experienced iGaming professionals who had a specific idea about how a new slot studio should be built: data first. Before a single game went live, Just Slots secured a €1.125 million investment from Yolo Investments, one of the most active venture capital firms in the iGaming space, and signed a strategic partnership with Stake.com, one of the world’s largest crypto-friendly betting operators, giving debut releases an exclusive early access window on a platform with a huge and engaged player base. By September 2024, before the first game had even launched, the infrastructure was in place.
Sugar Heaven arrived in November 2024. A candy-themed 5×3 slot with 20 fixed paylines, sticky wilds carrying multipliers up to 10x, a Super Wild that triggers one of four enhancement features during free spins, two bonus buy options, and a maximum win of 5,000x at an RTP of 96.42%. The engagement metrics that followed were the kind that make investors and operators pay attention: a 34% player return rate and close to 10% of all players logging more than 200 spins per session. For a debut release from a brand new studio those are genuinely strong numbers.
February 2025 brought Shogun Skylord, a bold stylistic departure that traded candy colours for feudal Japan with an avian samurai twist. Running on an expanded 5×6 grid with 40 win lines, the game featured free spins with progressive multipliers, a HotSpin ante bet that increases scatter frequency for a proportionally larger stake, two bonus buys, and a 10,000x maximum win at a 96.34% RTP.
Cyber Egypt followed in May 2025 as a timed Stake exclusive, merging ancient Egyptian mythology with futuristic AI aesthetics on a 5×3 grid with 20 paylines and multi-hour wild symbols, carrying an RTP of 96.42%. The concept of digital pharaohs running AI-powered empires felt genuinely original, and the execution matched the ambition. Book of Abyss arrived with the studio’s most aggressive win ceiling yet, an extraordinary 150,000x maximum win with a Free Spins Gamble feature that lets players spin wheels to upgrade their expanding symbol, starting multiplier, and bonus parameters before the bonus begins. Unholy Mystery, Fish Mafia with its Tween Reels mechanic, Book of Arcane 100, and Vegan Nightmare have since expanded a catalogue that now sits at around 10 titles with more in the pipeline.
The studio has been deliberately transparent about its methodology. Alongside Yolo Investments, Just Slots has partnered with Future Anthem’s Amplifier AI Optimise module through Tequity’s RGS, using machine learning trained on billions of bets to feed player behaviour data directly back into the game development process. Distribution has expanded through SOFTSWISS from September 2025, alongside aggregator partnerships with Hub88, Rhino Entertainment, Alea, Elantil, and iGamingDeck. The stated roadmap targets 10 games in year one and 18 in year two, all exclusively slots, with RTPs sitting consistently in the 96.18% to 96.51% range and volatility running predominantly high across the catalogue.
“Just Slots is one of the most interesting new studios I have come across in a while. The data-driven approach is not just marketing talk, you can see it in how well their games perform with players. Sugar Heaven hooked a lot of people and Book of Abyss has a 150,000x ceiling that is genuinely hard to ignore. A studio worth watching very closely.” Mark, Content Editor
“Really impressed with Just Slots. Sugar Heaven was a great debut and Shogun Skylord showed they have real creative range. The HotSpin mechanic is a clever way to give players control over bonus frequency and the Stake exclusives strategy has given them brilliant exposure. One of the more exciting new studios out there right now.” Scotty T, Fruity Slots Streamer
FAQs about Just Slots
-
How did a studio founded in 2024 secure Stake.com as a launch partner before releasing a single game?
Just Slots locked in a strategic partnership with Stake.com in September 2024, two months before their debut title Sugar Heaven launched in November. The Stake relationship provides the studio with a timed exclusive window on one of the world’s most-played crypto-friendly betting platforms before wider distribution. Combined with the €1.125 million Yolo Investments backing secured in early 2024, the studio arrived with infrastructure most new developers spend years building. -
What is the HotSpin mechanic?
HotSpin is Just Slots’ proprietary ante bet feature that appears across multiple titles. It increases the player’s total stake by a set percentage in exchange for a higher scatter frequency during that spin, making it more likely to trigger the free spins round without guaranteeing it. The cost varies by game, ranging from an extra 200% of the base bet in Unholy Mystery up to 400% in Shogun Skylord, giving players a way to tilt the odds of triggering the bonus without going straight to a full bonus buy. -
What makes Book of Abyss notable in the catalogue?
The maximum win of 150,000x makes it the highest ceiling in the entire Just Slots portfolio by a significant distance. The game includes a Free Spins Gamble Feature where players spin three separate wheels to choose their expanding symbol, set their starting multiplier, and pursue the highest possible combination before the bonus begins. Each gamble risks losing the awarded free spins entirely, creating a risk-reward decision that changes how the feature plays out. -
How does the studio use AI in game development?
Just Slots has integrated Future Anthem’s Amplifier AI Optimise module through Tequity’s RGS platform. The system processes billions of bet events to build player behaviour clusters and measures game launch and performance data in real time, feeding insights directly back into development decisions. The goal is to ensure new releases are built on a foundation of actual player engagement data rather than intuition alone. -
What is the volatility and RTP range across the catalogue?
The portfolio sits predominantly at high to very high volatility. RTPs range from 96.18% in Vegan Nightmare through to 96.51% in Unholy Mystery, with Sugar Heaven at 96.42%, Shogun Skylord at 96.34%, and Cyber Egypt at 96.42%. Maximum wins span from 5,000x in Sugar Heaven up to 150,000x in Book of Abyss. -
Where are Just Slots games available?
Distribution covers Stake.com as a timed exclusive launch partner, with wider availability through SOFTSWISS from September 2025 and aggregator partnerships including Hub88, Rhino Entertainment, Alea, Elantil, and iGamingDeck.
