Oros Gaming Slots: Every Game & the Studio Behind Them
Oros Gaming is a Reno, Nevada-based slot studio founded in 2021 by designers and executives who spent decades building land-based cabinets for IGT, VGT and Aristocrat before turning to online games. The studio’s first releases, 9 Bass and Chilli Inferno, launched in August 2022, and it has since grown a catalogue of around two dozen titles distributed exclusively through Games Global, with further reach via Microgaming and EveryMatrix. On SlotsLike, 9 Bass and Aztec Might Cash Spree both carry full reviews, with more of the catalogue to follow.

Top Oros Gaming Slots
Two Oros Gaming titles are reviewed on SlotsLike so far, and the two cards below cover them. The rest of the studio’s catalogue, researched from Oros Gaming’s own site, is listed as plain text underneath rather than linked, since those pages do not exist here yet.
The studio’s December 2024 Cash Spree entry, charging a 10x free spins multiplier and up to 12 sticky spins during ordinary base-game play before either bonus is triggered.
The studio’s debut alongside Chilli Inferno, a 5×3 fishing slot built around the scatter-pay Epic Strike system and a 3x Free Spins wheel.
The rest of the catalogue, in no particular order: Chilli Inferno (9 Bass’s launch partner, a Link&Win collection slot with a WinBooster multiplier), Cash Spree Gold, Cash Spree Dragon, Cash Spree Fishin’, Cash Spree Phoenix, Cash Spree Triton, Cash Spree Pegasus 2 and the wider Cash Spree line (scatter-collection games sharing 9 Bass’s cash-prize instincts), Magnificent Power Zeus, Magnificent Power Apollo, Magnificent Power Bastet, Magnificent Power Spartan, Magnificent Power HooKoo, Magnificent Power Leprechaun, Magnificent Power Gold, Magnificent Power Wolf Fire Spirit and Magnificent Power Hera’s Crown (a mythology-led series with expanding-symbol mechanics), Action Strike Vault (a heist theme carrying the Epic Strike scatter system), Big Mouth Fishin’ (a second fishing title alongside 9 Bass), Iron County Outlaw (the studio’s Western release), Joker Bonanza Cash Spree, Joker Rush Cash Spree and Premier Joker Cash Spree (a joker-themed sub-set of the Cash Spree line), and Quick Cash, a simpler standalone cash-prize title.
Features Oros Gaming Is Known For
Epic Strike Scatter Prizes
Oros Gaming’s signature mechanic pays a cash prize whenever enough of a game’s core symbol lands anywhere on the reels in one spin, rather than needing a specific payline. 9 Bass introduced it with its Bass fish scatter, paying from 1x stake for three symbols up to 2,000x for nine, and the same underlying system carries through to Action Strike Vault under the Epic Strike name.
A different studio’s take on scatter-triggered cash prizes, useful for comparing against Oros Gaming’s Epic Strike approach in 9 Bass.
Free Spins Wheels with Fixed Multipliers
Rather than variable or increasing multipliers, Oros Gaming’s free spins rounds tend to run a single fixed multiplier across the whole bonus, decided by a wheel spin at the trigger. 9 Bass runs a flat 3x through its 10 to 30 free spins, keeping the bonus simple and predictable once it starts.
A higher-volatility free spins slot from a different studio, a useful contrast to Oros Gaming’s steadier, fixed-multiplier approach.
Related Theme: Fishing Slots
9 Bass puts Oros Gaming firmly in the fishing-slot sub-genre alongside its Cash Spree Fishin’ and Big Mouth Fishin’ titles. It is a crowded theme with plenty of established names, and the cards below show where 9 Bass sits next to some of the better-known entries.
The genre-defining bass slot from Reel Kingdom and Pragmatic Play, using a fisherman Wild rather than Oros Gaming’s scatter-pay structure.
Another bass-fishing scatter-pay slot from a different studio, a close cousin to 9 Bass in both theme and mechanic.

About Oros Gaming
A Land-Based Pedigree Rebuilt for Online
Oros Gaming is not a typical iGaming startup. The studio was founded in 2021 out of Reno, Nevada by a team of designers and executives who spent the earlier parts of their careers building physical slot cabinets for some of the biggest names in land-based gaming, IGT, VGT and Aristocrat among them. That background shows up directly in the studio’s early releases: 9 Bass and Chilli Inferno, both launched in August 2022, favour the kind of classic 5×3 reel layouts, bold symbol sets and cabinet-style presentation that a Vegas casino floor veteran would recognise instantly, rather than chasing the elaborate cluster-pays and cascading mechanics that dominate a lot of newer online-first studios.
The Name and the Philosophy
Oros takes its name from the last four letters of “ouroboros”, the ancient symbol of a serpent eating its own tail, representing an endless cycle of renewal. The studio has framed this as a guiding idea for how it builds games: taking proven land-based mechanics and continually reworking them for a new online audience rather than treating physical and digital gaming as separate disciplines. It is a smaller outfit than most of the studios reviewed on this site, but the pedigree behind it is genuine rather than a marketing line.
Growth Through Games Global
Oros Gaming’s content is released exclusively through Games Global, the aggregator and platform business that also distributes Microgaming-branded titles, with a December 2022 partnership announcement marking the studio’s move into wider distribution. That relationship, along with investment from London-based Velo Partners, has let a young studio scale its catalogue to around two dozen titles within a few years, built mostly around a small number of recurring series (Cash Spree, Magnificent Power) rather than one-off releases, which keeps production costs manageable for a studio of its size.
Where 9 Bass Fits
As one of Oros Gaming’s first two games, 9 Bass is a useful entry point for understanding the studio’s whole approach: a classic layout, a scatter-pay core (later formalised as the Epic Strike system across the catalogue), and a straightforward free spins bonus with a flat multiplier rather than an escalating one. It is not the studio’s biggest or most elaborate release, but it set the template that a lot of what followed has stuck to.
