Monstrums
Monstrums is a slot studio behind Porkageddon, developing mystery box games under the Juice group spun off from Stake in September 2025, with Australia listed as its jurisdiction on the provider’s own site.
Its games moved from a Stake-only arrangement to wider distribution only recently, so most casinos have not yet added the catalogue and the studio's footprint stays small for now.

Monstrums Casinos — Games, Fairness and Where to Play
Monstrums is a slot studio built around mystery box mechanics, listing Australia as its jurisdiction according to schema data on monstrums.com. Its title Porkageddon sits in the catalogue at Stake, a Curaçao-licensed operator, and the studio itself only became available beyond Stake in September 2025 as part of the Juice spin-off.
Who Is Monstrums
Monstrums lists Australia as its jurisdiction, according to schema data published on monstrums.com. The studio produces slot games and operates within the Juice group, the set of studios that Stake spun off into an independent operation in September 2025. Before that spin-off, Monstrums titles were available exclusively on Stake.com; according to iGamingBusiness, any operator could carry the games only from that point forward, and Roobet was reportedly the first operator to go live with Juice content, Monstrums included.
Across the 514 slot studios ranked by how many casinos in the catalogue carry their games, Monstrums sits at position 491, tied with studios such as Jili, MadLab and Mount Olympus at one casino apiece, while G Games is carried by 6 casinos, and Hacksaw leads that same scale with 128 casinos carrying its games. The gap says less about game quality and more about how recent Monstrums' wider distribution still is.
Games and Signature Mechanics
Monstrums builds slot games, and its listed title is Porkageddon, currently available in the Stake casino catalogue. Rather than sticking to a classic reel-and-payline format across its whole portfolio, the studio develops mystery box games as one of its verticals — it "develops emerging verticals such as Mystery Boxes,". Juice itself describes Monstrums as its "new-verticals studio, starting with Mystery Boxes, where players open boxes for real-world prizes from cars to consoles," per Juice's own September 2026 announcement.
For a player, that format reads differently from a standard slot. Instead of spinning reels for a multiplier, a mystery box round centers on opening a box whose contents come from a listed prize table, so the payout is defined by what sits inside the box rather than by symbol combinations across paylines. That changes what to check before staking: the box's prize table and how it is weighted matter as much as a slot's paytable, even though the on-screen presentation looks closer to a pick-and-reveal game than to a five-reel machine.
RTP, Volatility and Fairness
Monstrums does not publish RTP or volatility figures that can be confirmed here, which is not unusual for a studio whose games only moved beyond Stake in September 2025. The Curaçao Gaming Authority licenses Stake, the casino currently carrying Monstrums games. Across the casinos in this hub, active bonuses feature wagering requirements starting at 40x, with matches up to 200%. Readers who want to compare that licence against other regulated operators can check the Licensed Casinos hub.
Roobet was the first operator to go live with Juice games, Monstrums content included, after the September 2025 spin-off — a sign that the studio's distribution beyond Stake is still recent enough that most casinos have not added it yet.
Where to Play Monstrums Games
The casino list above shows where Monstrums titles are currently available, led by Stake, which holds a Curaçao licence. That single entry reflects how new the studio's wider distribution is: Monstrums games left an exclusive arrangement with Stake only in September 2025, per iGamingBusiness, so most operators have not added the catalogue yet. Players who prefer to fund play with crypto can check Tether (USDT) casinos, since USD Coin and BCH (Bitcoin Cash) sit among the payment methods used by casinos already carrying Monstrums games, alongside Visa, Mastercard, and Maestro, and mobile-first players can look at the Mobile Casinos hub before assuming a mystery box title runs well on a phone browser.
- Holding structure: Monstrums operates as part of the Juice studio group rather than as a fully independent developer, so support and distribution terms may follow Juice's deals rather than a single publisher's policy.
- Casino count: with one casino in the catalogue currently carrying Monstrums titles, a lobby listing the studio today is not guaranteed to keep the games long-term if distribution stays this limited.
- Licence that actually governs play: Monstrums lists Australia as a jurisdiction on its own site, but the licence covering real-money play is the casino's — currently Curaçao at Stake.
Common Misconceptions
- New studio means unverified fairness: Monstrums only left its Stake-exclusive arrangement in September 2025, per iGamingBusiness, so the games are new to a wider audience — a limited casino count is a distribution fact, not proof of unaudited game math.
- Mystery boxes work like a slot bonus round: a mystery box game centers on opening a box for a listed prize rather than lining up symbols across paylines, so the two formats should be read differently before staking.
- Hot and cold streaks: outcomes are generated independently round to round, so a slot or box-opening title is never "due" a win after a losing run.
- RTP as a short-session promise: return-to-player is a theoretical figure calculated over a long run of rounds, not an outcome a single session should be expected to match.
Conclusion
"Monstrums is a young mystery-box studio riding on Juice's distribution, worth checking for its box-opening format rather than for a deep back catalogue."
Monstrums fits a player curious about a mystery-box format rather than classic reels, and comfortable trying a young studio with a single-casino footprint in the catalogue for now. Players who want a deep library or years of published RTP history should treat Monstrums as one title to sample in demo mode first, not as a full session's worth of variety.

Monstrums – FAQ
Which casinos carry Monstrums games?
Stake is the casino in the catalogue currently carrying Monstrums titles; it holds a Curaçao licence. Distribution widened only in September 2025 when Monstrums left its Stake-exclusive arrangement, so the list is still short.
What is the most notable Monstrums game?
Porkageddon is the notable slot title from Monstrums, available at Stake. Monstrums also develops mystery box games as a separate vertical, where players open boxes for listed prizes rather than spin reels.
How does a Monstrums mystery box game differ from a classic slot?
A mystery box round centers on opening a box whose contents come from a prize table, so the payout depends on the box's contents rather than on symbol combinations across paylines and reels.
Is Monstrums independently audited?
No specific audit or RTP figures for Monstrums are confirmed here. The casino carrying its games, Stake, operates under a Curaçao licence, and the Curaçao Gaming Authority records no bonus or payout caps for that licence.

No. Monstrums games were exclusively available on Stake.com until September 2025, when Stake spun the studio off into the Juice group, opening the catalogue to other operators, according to iGamingBusiness.
