What Spinberry is shipping now

7 dated releases · 4 months

NextSlots tracks new and upcoming releases rather than back catalogue, so this is the current Spinberry run and not everything the studio has made: 7 titles on file, dated 23 Jul 2026 to 15 Oct 2026. 4 of them are out, 3 are still ahead of us, and every date moves on its own as the feed moves.

A studio gets its own release calendar once we track 8 or more of its slots, and Spinberry sits at 7. Its dated releases are listed in the month archives: July 2026, September 2026, October 2026.

STUDIO FILE / PUBLISHED SPECS

Spinberry specs, title by title

4 of 7 publish an RTP

Of the 7 Spinberry titles we track, 4 publish an RTP, 3 carry a volatility grade and 1 name a core mechanic. Each figure below is computed from those titles only, so it describes what the studio has published and not the rest of the run. That is a small sample: 4 RTPs, so read the median as a marker rather than a house average.

Every RTP here is the figure the studio published for that title, as held in our registry. Titles that publish no RTP are left out of the table and out of the median rather than filled with a house average.

“Facts checked” is the day this game's specs were last verified against the studio's own source. Anything older than 90 days is queued for another look before it stays on the site. The desk plays what it can open, but it does not file a session log per game, so no spin count is printed here.

STUDIO FILE / REVIEW

Spinberry at a glance

Updated 29 Jul 2026

Spinberry is a Tallinn-based studio with a UK Gambling Commission licence and 119 games on our data source, which puts it 41st of the 80 studios we track for catalogue size. The figure that stands out is return to player: across the 20 titles that publish one, the median is 93.17%, below the 95.7% the studios we track average, and too few titles carry a volatility rating for us to call a lean either way.

  • Head office in Tallinn, Estonia, and the studio holds a UK Gambling Commission licence. A founding year is not on record, so we do not state one.
  • 119 games on our data source, 51 of them with a dated release, ranking 41 of the 80 studios we track for size.
  • Median RTP 93.17% and an average of 93.19% across the 20 titles that publish a figure, against a field average of about 95.7%.
  • The published RTPs sit in a tight band, from 93.12% to 93.26%.
  • Release pace on the feed: 6 dated titles in 2024, 27 in 2025 and 18 carrying a 2026 date.

Who is Spinberry?

Spinberry runs its head office in Tallinn, Estonia, and holds a UK Gambling Commission licence, which is the part that matters if you are playing from Britain. A founding year is not on record in our data, so we leave it out rather than guess at one.

On scale, our data source lists 119 games under the studio. Of those, 51 carry a dated release, so roughly two thirds of the catalogue reaches us without a date attached and sits outside any timeline we can draw.

The dated record runs from 1 October 2024 at the oldest to 15 October 2026 at the newest. That is a short window, and it says more about when the feed started carrying Spinberry than about how long the studio has been building slots.

Release pace across the dated titles breaks down like this:

  • 2024: 6 dated releases
  • 2025: 27 dated releases
  • 2026: 18 dated releases, the latest of them dated 15 October 2026

2025 is the busiest year on the feed by a clear margin. Read the yearly counts as a picture of the dated slice only, not of everything the studio shipped.

What Spinberry builds: themes across the catalogue

Across the catalogue on our data source, the themes that come up most often are:

  • Sports: 6 titles
  • Christmas: 6 titles
  • Fish: 5 titles
  • Asian: 4 titles
  • Fruit: 4 titles
  • Halloween: 4 titles

Two of the top six are calendar themes, Christmas and Halloween, which points to a studio that ships to a seasonal schedule as well as an evergreen one. Sports and Fish sitting alongside them suggests the spread is broad rather than built around a single house style.

None of these counts is large against a catalogue of 119 games, so no theme dominates. Titles can carry more than one theme tag, and the counts only cover games that publish a theme at all.

Spinberry RTP and volatility across the catalogue

Only 20 of the 119 games on our data source publish an RTP. Across those, the median is 93.17% and the average 93.19%, which is close enough to say the sample has no outliers pulling it around.

The full range runs from 93.12% to 93.26%. That is a spread of a fraction of a percentage point across twenty games, which is unusually tight and reads like a consistent house setting rather than a figure tuned game by game.

The studios we track average about 95.7%, so Spinberry's 93.19% sits below the field by a little over two percentage points. On a long run of play that gap is real money: a lower theoretical return means more of your stake stays with the house over time, whatever happens in a single session.

One caveat that applies across the industry. Studios often supply the same game at more than one RTP setting and the operator picks which version to run, so the figure in the paytable of the game you actually load is the one that counts. Check it in the game itself rather than trusting a number quoted anywhere else, ours included.

On volatility we have to pass. Too few Spinberry titles carry a rating for us to describe a catalogue lean, and guessing at one from a handful of games would be worse than saying nothing.

The mechanics Spinberry builds on

Across the Spinberry titles we track and have played, one mechanic is on record: Reel Respins, which appears in Super Tuna Overload. Respins hold part of the screen in place and spin the rest again, which is a way of extending a single result rather than starting a fresh one.

That is a thin slice of a 119-game catalogue, so treat it as what we can confirm rather than a summary of how Spinberry builds. As the desk plays more of the range this section will grow.

Worth knowing if you are playing from Britain: feature buys are not permitted at GB-licensed casinos. If you see a buy button in a demo or in coverage written for another market, it will not be there in the UK version of the game.

Notable Spinberry slots

By published RTP, Book of Deities and Championship Fortunes share the top of the list at 93.26%, with Golden Plunder and Voyage of Wealth a shade behind on 93.25%.

Below them the drop is slight: 10x Minimum Magnetic Force at 93.24%, 243 Coins of Fortune at 93.23%, Ocean Kings at 93.22% and Turkey Day at 93.21%. Picking the highest-RTP Spinberry game over the eighth-highest gains you a rounding error, so choose on how the game plays instead.

On the newest side, the two titles we track and can link are Rainbow of Stars, released 30 July 2026, and Super Tuna Overload, released 23 July 2026 with an RTP of 93.29% and a Reel Respins feature. Super Tuna Overload's figure sits fractionally above the top of the published range in the wider catalogue sample.

How Spinberry compares to the field

Set against the 80 studios we track:

  • Size: 119 games ranks 41 of 80, so squarely mid-table rather than a small shop or a back catalogue giant.
  • RTP: an average of 93.19% against a field average of about 95.7%, which puts Spinberry below the field by a little over two percentage points.
  • RTP consistency: a published range of just 93.12% to 93.26%, tighter than you would expect from a catalogue tuned game by game.
  • Volatility: we cannot place Spinberry, because too few of its titles carry a rating. For context, 21 of the 53 studios we can rate lean Very high, so a high-variance catalogue is common rather than a distinguishing feature.

The one comparison that should shape your choice is the RTP gap. Everything else here is mid-field.

Playing Spinberry slots as free demos

A demo is the real game running on play-money. Same reels, same features, same maths, with the only difference being that the balance is not yours.

That makes it the cheapest way to find out whether a game suits you: how fast it plays, how often a feature turns up, whether the base game holds your attention. Play a decent stretch rather than a dozen spins, because a short demo run tells you almost nothing about pace.

Demos on GB-facing sites sit behind an 18+ age check, so expect to confirm your age before a game loads. And remember a demo cannot show you the payout over time; that is what the RTP figure is for.

How we track Spinberry

The catalogue statistics on this page come from the Spinberry listing on our data source, and each figure is computed only from the titles that publish it. The RTP numbers rest on 20 games, the release counts on the 51 with a date, and the theme counts on whatever carries a theme tag.

The reviews are separate. Those come from individual releases the desk plays, which today is a small current slice of the range rather than the whole thing.

So we are not claiming to have played all 119 games, and we will not pretend otherwise. When the underlying data changes, the figures here change with it.

STUDIO FILE / FAQ

Spinberry FAQs

Is Spinberry licensed in the UK?

Yes. Spinberry holds a UK Gambling Commission licence, and the studio's head office is in Tallinn, Estonia.

Which Spinberry slot has the highest RTP?

Of the titles that publish a figure on our data source, Book of Deities and Championship Fortunes share the top spot at 93.26%, followed by Golden Plunder and Voyage of Wealth at 93.25%. Among the games we track ourselves, Super Tuna Overload publishes 93.29%.

How many games has Spinberry made?

Our data source lists 119 Spinberry games, 51 of which carry a dated release. That catalogue size ranks 41 of the 80 studios we track.

Are Spinberry slots high or low volatility?

We cannot say. Too few Spinberry titles carry a volatility rating for us to describe a lean across the catalogue, so we leave it open rather than guess.

Can I buy the bonus feature in a Spinberry slot in the UK?

No. Feature buys are not permitted at GB-licensed casinos, so a buy button you see in a demo or in coverage aimed at another market will not appear in the UK version.

Can I play Spinberry slots for free?

Yes. Demos run the real game on play-money, with the same reels, features and maths, and on GB-facing sites they sit behind an 18+ age check.
