Spinberry Slots and Where to Play (2026)

By Jack Henshaw, Head Writer · Published 6 July 2026 · Last updated 10 July 2026

Spinberry is the Estonian studio that spent its first two years building land-based cabinets for the 1PT Group before ever shipping an online slot — its online debut, Drop the Wilds, only went live in June 2022 via Pariplay’s Ignite programme. Since then it has built a roughly 70-strong catalogue leaning hard on a “Wilds” naming convention and a house-patented Feature Spin mechanic, and picked up a genuine US casino-brand distribution deal with Caesars Digital in 2024. Our verdict: 5/10. This Spinberry review covers the best Spinberry slots ranked, the Feature Spin mechanic, the UKGC-licensed Spinberry casinos that carry the games, and the full licence file.

Where to Play Spinberry Slots

Spinberry at a glance

The essentials — an Estonian studio that came to online slots by way of land-based cabinets, not the other way round.

The best Spinberry slots: 10 games that actually matter

From the studio’s pinball-flavoured debut to its most recent Caesars-distributed features — ten games that show how a land-based cabinet maker built an online identity almost entirely around wilds. RTPs quoted are typical published defaults; several sources disagree by a point or two, which is common for a studio whose games ship in several regional builds. The full ranked catalogue is near the end of the page.

1. Drop the Wilds (2022)

Spinberry’s first-ever online release and still its most distinctive: a disco-industrial theme built around a genuine pinball table-of-chance. Land one or two Free Spins symbols in view and a small ball drops down a pinball board, its resting slot determining how many wild symbols get delivered onto the reels for the free-spin round that follows. Published figures vary by build, but the higher-volatility version quotes a startling 188,500x max win on a 95%-region RTP and high volatility — among the biggest published ceilings of any small studio we’ve covered.

2. El Gran Chigüiro (2023)

A capybara-and-jungle theme on a 5×4, 1,024-ways grid with cascading reels, a buy-feature option and Spinberry’s Feature Spin bonus layered on top. Published RTP of 96.22% is comfortably the highest in the catalogue we could verify, with a quoted max win of 4,000x — more conservative than Drop the Wilds, but the studio’s best-reviewed maths.

3. Circus Riches

A big-top circus theme, also on the 1,024-ways layout, with a ticket-collection free spins bonus and a published max win around 25,000x — the highest ceiling we found outside Drop the Wilds itself. Published RTP is reported inconsistently across review sites (readings from 91% to 96% appear depending on build), which is exactly the kind of gap Spinberry’s own paytable resolves in seconds; always check it before playing.

4. Buffalo Wilds

An American-plains buffalo theme on 243 ways, running both the Spectacular Link feature (linked symbols pay cash and jackpot prizes) and a Feature Respin option — the clearest single example of Spinberry’s two named Caesars-era mechanics working together in one game. Published RTP sits around 93%, though a couple of sources quote nearer 96% for an alternate build.

5. Revved Wilds (2022)

A motorsport-flavoured entry from the studio’s first full year online, running a comparatively modest published RTP of 95.12% and a max win quoted at 2,500x on most builds (one source claims up to 5,000x). Solidly mid-table rather than a genuine standout, but a useful marker of how quickly Spinberry settled into a house style after Drop the Wilds.

6. Spinberry Wilds

The studio’s self-titled flagship, high volatility with a published RTP around 95.14% and a max win quoted at 2,500x — a fairly plain wilds-and-multipliers build that leans on the Spinberry name itself rather than a distinct mechanic, in a catalogue where most titles are built around a specific named feature.

7. Mega Drop The Wilds

A direct sequel to the studio’s debut, keeping the pinball-chance wild-delivery mechanic but on a published RTP of 93.38% — noticeably lower than the original. It’s a pattern common across small studios chasing a hit: revisit the mechanic that worked, sometimes at the cost of the maths that made it worth playing.

8. 1 Drop (2024)

One of the newer catalogue entries, running 1,024 ways with a published RTP of 94.23%. Its own mechanic is a weather-themed drop feature, not Feature Spin: silver and gold raindrops build up behind the reels and, when an umbrella symbol lands on the third reel, transfer onto the grid as wilds — gold raindrops double as free-spins scatters, awarding 10, 15 or 20 free spins with an escalating win multiplier. A different drop-based idea to Drop the Wilds’ pinball table, built with the same underlying instinct for randomised wild delivery.

9. Turkey Day

An American-football-meets-Thanksgiving theme (a helmeted turkey mascot, goalposts, autumn leaves) with a published RTP of 93.21% — one of the catalogue’s more overtly novelty themes, and a fair example of Spinberry’s willingness to chase a calendar tie-in rather than build around a single mechanic family.

10. Irish Wilds

A St Patrick’s Day leprechaun-and-pot-of-gold theme, one of several “Wilds”-suffixed titles in the catalogue, with a published RTP reported around 96% — among the higher published figures we found, though we’d treat it as a “typical default” rather than a universal constant given how often Spinberry’s own numbers shift between builds.

Spinberry vs the studios it competes with

Spinberry fights in the small-catalogue, aggregator-distributed bracket — studios that lean on a platform like Pariplay’s Fusion rather than building their own distribution network. Against our previously reviewed studios:

The honest read: Spinberry is the smallest and most US-facing of this bracket — its Caesars Digital deal is a genuinely unusual distribution win for a studio this size, but its catalogue depth and published-RTP consistency both lag Boldplay’s wider aggregator spread and Leander Games’ much larger legacy library. What Spinberry has that neither rival can claim is a real land-based pedigree behind it, via 1PT Group’s UK gaming-machine software history.

The game families, in depth

A catalogue organised loosely around theme and a repeated “Wilds” naming habit rather than tightly defined mechanic families. The full ranked list covers the rest.

The Drop the Wilds line

Drop the Wilds and its sequel Mega Drop The Wilds both run the pinball-chance wild-delivery mechanic that gave the studio its name recognition, though the sequel’s lower published RTP suggests the format was tuned differently the second time round.

The “Wilds”-suffixed catalogue

Spinberry Wilds, Irish Wilds, Buffalo Wilds, Revved Wilds and All About the Wilds all share the naming convention without sharing a single defined mechanic — more a branding habit than a genuine game family, which makes the catalogue harder to navigate than a studio built around one clear engine.

The Caesars-era feature titles

Buffalo Wilds is the clearest showcase of Spectacular Link (linked symbols paying cash and jackpot prizes), one of the two mechanics Spinberry specifically promoted through its 2024 Caesars Digital partnership alongside Feature Spin, the 3×1 mini-reel awarding free spins that Spinberry Wilds introduced when it debuted on Light & Wonder’s OpenGaming platform back in February 2023.

Signature mechanics & technology

Spinberry’s toolkit is smaller and less consistently applied than most studios on this site, but two features are genuinely its own:

Feature Spin™ (patent pending)

The studio’s headline mechanic, described on its own site as a “Bet Chance” and “Special Play Mode” system: in practice, a 3×1 mini-reel that spins to determine a set number of awarded free spins, distinct from a standard scatter-triggered bonus round. Spinberry lists this as patent pending on its own marketing material, which if accurate would make it one of the few genuinely proprietary mechanics among small aggregator-distributed studios.

Spectacular Link & Spectacular Link Frenzy

A linked-symbol feature that pays cash and jackpot prizes when enough matching symbols land connected on the reels, promoted specifically through the Caesars Digital partnership announced in August 2024 alongside Feature Spin and Feature Respin.

The Drop the Wilds pinball-chance mechanic

A genuine hybrid of bagatelle/pinball and slots: a small ball drops through a pinboard of pockets, and whichever pocket it lands in determines how many wild symbols get transferred onto the reels for the free-spin round. It’s the single most distinctive piece of game design in the catalogue, even if the sequel didn’t quite repeat the original’s maths.

Spinberry slots RTP: the real numbers

The defaults: mostly clustering in the 93–96% band across the titles we could verify, with El Gran Chigüiro’s 96.22% the highest confirmed figure and Turkey Day’s 93.21% among the lowest.

Multiple published figures, genuinely: more than most studios we’ve reviewed, Spinberry’s own games show real disagreement between review sites on RTP and volatility for the same title (Circus Riches has been quoted anywhere from 91% to 96%; Buffalo Wilds from 93% to 96%) — almost certainly because the game ships in different regional or operator-specific builds rather than any single site simply getting it wrong. Checking the in-game paytable before playing matters more here than for most providers on this site.

Max wins: Drop the Wilds carries the catalogue’s most striking published figure at up to 188,500x on its highest-volatility build, with Circus Riches (25,000x) and El Gran Chigüiro (4,000x) some way behind. Our responsible gambling guide applies as always.

From land-based cabinets to a Caesars Digital deal

The arc that matters: a studio that built its early identity making cabinets for land-based operators, then arrived online relatively late (2022) via an aggregator partnership — and inside two years had landed a direct distribution deal with one of America’s best-known casino brands, a genuine step up in visibility that most studios this size never reach.

The story behind Spinberry

Bill and Lena Zycinsky, and the 1PT Group platform

Spinberry isn’t an independent creative studio in the way many small developers on this site are — it’s a product division of 1PT Group, the Estonia-based technology consortium founded in 2013 by Bill and Lena Zycinsky, whose earlier work was largely in UK land-based gaming-machine software rather than online slots. That land-based-first history is genuinely unusual among the aggregator-distributed studios we’ve reviewed.

Stuart Pounder, running the studio day to day

Stuart Pounder holds the Managing Director role at Spinberry, and it’s his name attached to the studio’s own public statements on distribution deals rather than either Zycinsky’s — on the February 2023 Light & Wonder partnership he said simply: “The time is right to partner with Light & Wonder and leverage the multiple benefits that they bring to the table.” Bill Zycinsky, credited as Spinberry’s Chief Executive Officer in the studio’s own Caesars Digital announcement, fronted that later 2024 deal instead — a split that suggests Pounder runs the studio’s day-to-day commercial relationships under the Zycinskys’ wider ownership.

“We create happiness responsibly”

Spinberry’s own site frames its mission around a short manifesto built on that line — thinking ambitiously, setting industry standards, and building “profitable games with a difference” while prioritising player interests. It’s standard studio marketing copy, but the land-based-to-online conversion services 1PT Group also sells (alongside full-cycle game development and land-based consulting) suggest the philosophy is at least partly a genuine business model, not just a slogan.

A late arrival online, by design

Where most of the studios on this site launched online-first, Spinberry spent its first two years building land-based content before Drop the Wilds became its first online release in June 2022 — a sequencing choice that likely explains both its relatively thin online catalogue for a studio this age, and its comparative comfort with regulated, casino-brand-direct partnerships like Caesars Digital.

Is Spinberry fair? Licensing, regulation & the record

Checked against the Gambling Commission’s public register on 6 July 2026.

The licence. Spinberry OÜ holds UKGC account 58055, based in Tallinn, Estonia, with a Gaming Machine Technical Software (Remote) licence current and active since 31 December 2021. Verify it yourself on the UKGC public register.

The record. Clean: no UKGC enforcement action against Spinberry OÜ that we can find.

So is it fair? Yes — certified RNG across the catalogue, a clean and active UK licensing file, and distribution through Pariplay’s independently regulated Fusion platform as well as a direct Caesars Digital partnership that carries its own US state-level regulatory scrutiny.

The biggest Spinberry wins

A studio too new and too small to have a documented real-money jackpot record; the numbers that matter here are published max-win ceilings rather than verified payouts. Documented context only:

We could not verify a YouTube gameplay video for any Spinberry title via oembed at the time of writing — a small studio’s catalogue this new often simply hasn’t been covered on video yet, so we’re not fabricating a facade here. If that changes, this section will be updated.

Beyond the reels

The corners of the story the ranking competitors never reach:

A land-based pedigree most rivals don’t have

Most small aggregator-distributed studios we’ve reviewed started online and never touched a physical cabinet; Spinberry’s parent 1PT Group built its reputation the other way round, in UK land-based gaming-machine software, before Spinberry brought that experience online in 2022.

A genuine US casino-brand deal

The August 2024 Caesars Digital partnership is a real step up in distribution credibility for a studio this size — getting a named feature set onto Caesars Palace Online Casino and Caesars Sportsbook & Casino in regulated US states is the kind of placement most 70-title studios never reach.

A Light & Wonder deal that predates Caesars by 18 months

Less talked about than the Caesars Digital tie-up, but arguably the bigger structural win at the time: in February 2023 Spinberry signed with Light & Wonder, joining the OpenGaming content aggregation platform via its Playzido integration — an ecosystem Light & Wonder describes as delivering over 3,500 games to operators in regulated markets worldwide. Steve Mayes, Light & Wonder’s Digital Partnerships Director, put it plainly in the companies’ own announcement: “We’re really excited about Spinberry’s roadmap and can’t wait to help them get their games in front of players worldwide.” It’s the deal that put Feature Spin™, debuting in Spinberry Wilds, in front of a major aggregator’s operator network more than a year before Caesars Digital came calling.

A naming convention that doubles as a filing problem

With Drop the Wilds, Mega Drop The Wilds, Spinberry Wilds, Irish Wilds, Buffalo Wilds, Revved Wilds and All About the Wilds all live at once, Spinberry’s own catalogue is genuinely harder to browse than most rivals’ — a side effect of leaning on one word rather than one mechanic as the house identity.

The company behind the games

Spinberry’s own site is a small, single-page affair by studio standards — About Us, Vision & Mission, Products, Services and Our Partners, with no dedicated press room or leadership bios. Beyond the active UKGC licence already covered above, Spinberry doesn’t publicly list independent lab certifications (GLI, ISO or similar) on its own site the way some larger studios do; the one credential it does claim directly is “Feature Spin™ (PAT. PEND.)”, a patent-pending mark on its signature mechanic rather than a third-party compliance certificate. We’re stating that plainly rather than padding the section with certifications we couldn’t verify.

What the site does make clear is the studio’s dual land-based-and-online positioning: its stated services span full-cycle game development, QA testing, resource staffing, and — distinctively for a studio this size — land-based-to-online format conversion consultancy, a direct legacy of 1PT Group’s original UK gaming-machine software business. That’s the practical version of “we create happiness responsibly”: a small team monetising land-based expertise most online-first competitors simply don’t have.

New Spinberry slots: what’s launched for 2025–26

The state of Spinberry right now: continuing to expand its US distribution through Caesars Digital while adding to its “10x Minimum” side-bet sub-line, though public confirmation of specific 2025–26 release dates is thinner than for larger studios on this site.

We’d rather flag that this list is thinner than most on this site than pad it — Spinberry’s own release announcements are less consistently covered by trade press than the larger studios we’ve reviewed. Paytable first, always.

What players actually say

From forums and review-site comment threads where Spinberry is discussed as a competent but unremarkable small studio — our words, cons intact.

The love: Drop the Wilds’ pinball-chance mechanic draws consistent praise as genuinely different from the usual scatter-triggered free spins, and the Caesars Digital deal is noted favourably as a sign the studio is being taken seriously by a major US operator.

The gripes, plainly: the “Wilds”-suffixed naming convention makes the catalogue confusing to browse, published RTP and volatility figures disagree between sources more often than for most studios we’ve covered (a real transparency gap, whatever the underlying cause), and outside Drop the Wilds and El Gran Chigüiro, several titles read as competent rather than distinctive. All fair, and worth knowing before you go looking for a specific game by name.

Which Spinberry slot should you play?

The thirty-second version of everything above:

Our verdict on Spinberry

All Slot Providers score: 5/10 — a land-based-pedigree studio that arrived online late, built a real distribution win with Caesars Digital, but hasn’t yet matched that commercial credibility with a catalogue that’s either deep enough or mathematically consistent enough to rank alongside the bigger names on this site.

Spinberry suits players curious about a genuinely different bonus mechanic (the Drop the Wilds pinball feature is worth trying once) and anyone following which small studios are landing real US casino-brand deals. Look elsewhere if you want RTP figures you can trust without checking the in-game paytable every time — Boldplay’s wider aggregator spread or Leander Games’ much larger legacy catalogue both offer more consistent ground to stand on.
