Slots Like 9 Bass: Oros Gaming’s Debut and the Epic Strike Scatter Prizes
9 Bass was one of Oros Gaming’s first two releases, arriving in August 2022 alongside Chilli Inferno as the young Reno-based studio’s debut pairing. It runs on a straightforward 5×3 grid with 20 fixed paylines, carries a headline RTP of 96.24% that lands in the site’s Medium-High band, and Oros Gaming’s own material describes the maths model as low volatility, though several independent trackers class it as medium. Stakes stretch from £0.20 to £120 a spin, and the ceiling is 2,000x your bet, worth £240,000 at the top stake. The whole game is built around a fishing lodge full of red Sevens, tackle-box Wilds and lucky lures, with Bass fish scattered across the reels paying instant cash prizes and a Free Spins wheel waiting behind three scatter symbols. Anyone hunting for slots like 9 Bass will find the closest matches among other bass-fishing and scatter-pay titles, and we line up the best of them further down this page.

9 Bass keeps its base game simple: five reels, three rows, twenty paylines fixed from the moment you load the game. There are no cluster wins or expanding grids here, just a classic line-pay slot dressed up as a day on the lake, with a lakeside mountain backdrop behind purple reels that feel more Vegas cabinet than modern video slot. That land-based cabinet influence is not an accident; Oros Gaming was founded by designers who spent years building physical slot machines for IGT, VGT and Aristocrat before turning to online games, and 9 Bass wears that heritage openly.
The reel strips mix old-school fruit-machine symbols, BAR tiles and fishing lures, with red Seven symbols and a tackle-box Wild sitting above them in the paytable. The real draw, though, is the Bass fish itself. It behaves as a scattered symbol that pays a cash prize whenever three or more land anywhere on the reels in a single spin, regardless of payline, with the reward scaling sharply the more Bass symbols show up. A separate Free Spins wheel symbol appears on the middle three reels only, and stacking three of those triggers the bonus round proper.
Because the Bass scatter pays on its own terms rather than needing a specific line, 9 Bass tends to deliver smaller top-ups fairly often even outside the bonus, which softens the pace between the bigger swings that the free spins wheel can produce.
Symbols and Paytable
The Bass fish is the game’s signature symbol and its biggest prize: nine of them landing across the reels in one spin pays 2,000x stake, with the reward stepping down through 8 (500x), 7 (100x), 6 (40x), 5 (15x), 4 (5x) and 3 (1x). The red Seven is the next-strongest regular symbol, followed by the tackle-box Wild, which substitutes for every symbol except the Bass scatter and the Free Spins wheel. BAR tiles and a handful of colourful fishing lures fill out the lower half of the paytable, keeping the whole set firmly in classic slot territory rather than reaching for elaborate premium artwork.
Bonus Features Explained
The Epic Strike Scatter Prizes
Every Bass fish that lands on the reels counts toward the same spin’s scatter tally, and Oros Gaming brands this scatter-pay system Epic Strike across its wider catalogue. Three Bass symbols anywhere in view pays out immediately, and the prize climbs steeply as more join them, right up to the nine-symbol 2,000x top prize. It is a pay-anywhere mechanic rather than a jackpot pool, so the numbers are fixed multipliers of stake rather than a progressive or randomly seeded jackpot, but it gives the base game a scatter-pay safety net that a lot of straight payline slots do not have.
The Free Spins Feature
Landing three Free Spins wheel symbols on reels two, three and four in the same spin triggers the bonus. A wheel then decides the exact award, and Oros Gaming’s own material lists results ranging from 10 up to 30 free spins, all running with a 3x win multiplier applied throughout the round. Additional Free Spins symbols landing during the bonus itself can retrigger the feature and add further spins, so a well-timed round can run considerably longer than the initial wheel result suggests. With the multiplier active for the whole bonus, the Free Spins feature is where 9 Bass’s bigger wins realistically come from, rather than the base-game scatter pays alone.
Pros and Cons
Pros
- The Bass scatter pays cash prizes for three or more landing anywhere, so the base game keeps delivering top-ups without needing a specific payline to connect.
- A flat 3x multiplier runs across the entire Free Spins round, with up to 30 spins possible from the triggering wheel alone.
- 96.24% is a genuinely solid RTP for a debut release from a first-time studio, sitting in the site’s Medium-High band.
- The retrigger option during free spins means a strong bonus round can extend well past its starting allocation.
- A simple 20-payline, no-frills layout suits players who want an old-school cabinet feel rather than a feature-stacked modern slot.
Cons
- Sources disagree on the volatility rating: Oros Gaming’s own site calls it a low volatility math model, while most third-party trackers list it as medium, which makes it harder to know exactly what session pattern to expect.
- As Oros Gaming’s debut title, there is a smaller track record and player sample behind the published figures than a slot from an established studio would have.
- The Free Spins wheel needs three scatters on specific reels (two, three and four) rather than anywhere on the grid, which narrows the trigger slightly compared with an anywhere-pays scatter design.
- Outside the Bass scatter pays and the Free Spins wheel, there is little else to the feature set, no wilds multipliers, no pick bonus, no secondary mini-game.
- The classic cabinet visual style, while a nice nod to Oros Gaming’s land-based roots, will feel plain next to the more elaborate animation and sound design on newer releases from bigger studios.

Expert Take
9 Bass matters less for what it does than for who made it. As one half of Oros Gaming’s debut pairing, it set the tone for a studio built by land-based cabinet veterans who wanted to bring that Vegas-floor feel online, and the classic 5×3 layout, red Sevens and tackle-box Wild all read as a deliberate homage rather than a lack of ambition. The Epic Strike scatter-pay system it introduced has since become something of a house mechanic across later Oros Gaming releases. On its own merits, 9 Bass is a fairly gentle, approachable slot: a competitive RTP, a scatter pay that keeps the reels ticking over, and a Free Spins wheel with a flat multiplier that rewards patience more than it chases huge single spins. It will not be for players who want fireworks on every spin, but as an introduction to a new studio it did its job.

About the Developer
Oros Gaming is the studio behind 9 Bass, a Reno, Nevada-based developer founded in 2021 by designers and executives with decades of experience at land-based giants including IGT, VGT and Aristocrat. 9 Bass and Chilli Inferno were the studio’s first two releases, launching in August 2022, and Oros Gaming has since built out a catalogue of around two dozen titles distributed exclusively through Games Global, with additional reach via Microgaming and EveryMatrix. The name comes from the last four letters of “ouroboros”, the ancient symbol of ongoing renewal, which the studio has taken as shorthand for its own approach: land-based mechanics and cabinet-style presentation rebuilt for an online audience.
Since 9 Bass, Oros Gaming has leaned on a handful of recurring series rather than one-off releases. The Cash Spree line (Cash Spree Gold, Cash Spree Dragon, Cash Spree Fishin’, Cash Spree Phoenix, Cash Spree Triton and others) builds on the same scatter-collection instincts as 9 Bass, while the Magnificent Power series (Magnificent Power Spartan, Magnificent Power Zeus, Magnificent Power Apollo, Magnificent Power Bastet among them) takes the studio into mythology themes with expanding-symbol mechanics. Action Strike Vault carries the Epic Strike scatter-prize system 9 Bass introduced into a heist theme, and Chilli Inferno paired it with a Link&Win collection round and a WinBooster multiplier. None of these other Oros Gaming titles are reviewed on SlotsLike yet, so there are no internal cards to show here, but the pattern across the catalogue is consistent: classic cabinet-style reels, a scatter-pay core, and a free spins or collection round layered on top.

Frequently Asked Questions
How does the bonus work in 9 Bass?
Landing three Free Spins wheel symbols on reels 2, 3 and 4 in the same spin triggers a wheel that awards between 10 and 30 free spins, all running with a fixed 3x win multiplier. Further Free Spins symbols landing during the bonus can retrigger it and add more spins to the round.
What is the RTP of 9 Bass?
Oros Gaming’s published default RTP is 96.24%, which sits in the site’s Medium-High band. As with any slot, it is worth checking the live paytable screen at your chosen operator before staking, since configurations can occasionally vary.
What is the maximum win on 9 Bass?
The maximum win is 2,000x your triggering stake, which works out at £240,000 if you are playing at the top £120 stake. The biggest single-spin route to that figure is landing all nine Bass scatter symbols in one go, though a strong Free Spins round with its 3x multiplier is the more realistic path to a big win.
How volatile is 9 Bass?
Sources disagree here. Oros Gaming’s own site describes the maths model as low volatility, but independent trackers including SlotCatalog, Casinos.com and SlotBeats classify it as medium. In practice, expect the Bass scatter pays to keep smaller wins ticking over reasonably often, with the Free Spins wheel providing the bigger swings.
What are the best slots like 9 Bass?
Big Bass Bonanza and Big Catch Bass Fishing Megaways are the closest matches for the bass-fishing theme, while Bass Blitz and Bass Brothers offer their own takes on the same scatter-pay sub-genre with a different pace and feature set.
Can I play 9 Bass for free?
Yes. A free-play demo is commonly available through a licensed casino’s game library, and a playable version is embedded further up this page. Real-money play is for over-18s at UK-licensed casinos.
Who makes 9 Bass?
Oros Gaming developed 9 Bass, releasing it in August 2022 as one of the Reno-based studio’s first two titles. The team behind it includes designers with decades of land-based cabinet experience at IGT, VGT and Aristocrat, and the game is distributed exclusively through Games Global.
Our Verdict on 9 Bass
9 Bass does not try to reinvent the wheel, and it does not need to. As Oros Gaming’s debut title, it leans on a familiar 5×3, 20-payline cabinet layout, adds a scatter-pay Bass fish that keeps the reels delivering small top-ups, and backs it with a Free Spins wheel that carries a flat 3x multiplier through every one of its 10 to 30 spins. The 96.24% RTP is a genuinely solid figure for a first release from a new studio, and the retrigger option gives a strong bonus round real room to grow. Where it comes up short is variety: outside the scatter pays and the free spins wheel there is little else going on, and the disagreement between Oros Gaming’s own low-volatility claim and independent trackers’ medium rating makes it slightly harder to know what pattern of session to expect. For players hunting slots like 9 Bass purely for the bass-fishing theme and a straightforward scatter-pay structure, it is a solid, unfussy introduction to a studio worth keeping an eye on.
