Elk Studios
slots

Elk Studios was founded in 2013 and works out of Stockholm, Sweden. On our data source the catalogue runs to 155 games, of which 115 carry a dated release, so roughly two in five entries have no date attached and cannot be placed on a timeline.

The oldest dated entry on file is 2016-11-02, which is three years after the studio was founded. That is a gap in the feed rather than a gap in the studio's history, so read the year counts below as what our source covers, not as a complete record of everything Elk Studios has shipped.

Within that window the output builds slowly and then settles. There is 1 dated release in 2016 and 9 in 2017, a quieter 5 in 2018, then a run of 10 in 2019, 12 in 2020, 12 in 2021, 13 in 2022 and 16 in 2023.

The last three years are the volatile part of the record: 5 dated releases in 2024, a jump to 23 in 2025, and 9 dated so far for 2026, with the newest dated entry on file carrying a 2026-08-25 date. A one-year dip followed by a four-fold rebound usually points to a change in release schedule or in how the feed catalogues titles, so it is worth treating 2024 as an outlier rather than a trend.

The themes recorded across the catalogue lean seasonal and dark, with the classic slot furniture kept in stock. The most common on our data source:

• Halloween: 11 titles
• Fruit: 11 titles
• Animal: 11 titles
• Horror: 6 titles
• Asian: 5 titles
• Fantasy: 4 titles

Halloween and horror together account for 17 titles, which is a real lean rather than a couple of one-off October releases. Fruit and animal themes at 11 each show the everyday ground is covered too, so the catalogue is not a single-idea studio.

Of the 155 games on file, 94 publish an RTP. Across those, the median is 95% and the average 95.1%, which is about as close together as two measures of the same set can sit. That closeness matters: it tells you there is no small cluster of unusually generous or unusually mean titles pulling the average away from the typical game, so the middle of this catalogue really is the middle.

The 80 studios we track average about 95.7%, so Elk Studios sits 0.6 percentage points below the field. In plain money, a 95.1% game carries a theoretical cost of about £4.90 per £100 staked against roughly £4.30 at the field average. That is nothing you would notice across ten spins, but stake recycles fast on slots, so on £1,000 put through a game it is a theoretical cost of about £49 against £43.

The published figures run from 94% to 96.4%, a spread of just 2.4 points. That is a narrow band, and it cuts both ways: there is no floor-scraping outlier to accidentally sit down at, and equally no headline high-RTP title to seek out. Wherever you land in this catalogue you are broadly in the same territory.

One caveat applies to every number above. Studios routinely ship a single game in more than one RTP configuration and the casino chooses which one to run, so the figure on any list, ours included, is one setting among several. The number in the game's own information panel is the version you are actually playing, and it is the only one that counts.

Volatility is where this catalogue has a clear personality. Across the 91 rated titles the split is 1 low, 5 low to medium, 11 medium, 50 high and 24 very high, so about four in five rated games sit at high or very high on the 1 to 5 ladder.

In practice that means the balance drains between features rather than ticking along on small wins, and dry stretches are normal rather than a sign something is wrong. The payout is concentrated in the feature rounds, which is exactly why these games can look flat for a long time and then move quickly.

The sensible adjustment is stake size, not session length: a smaller spin stake buys the spins you need to reach a feature without the balance disappearing first. Judging one of these games on 50 spins will tell you almost nothing about how it actually pays.

The mechanics recorded in the Elk Studios titles our desk tracks directly:

• CollectR: recorded in Pirots 5, released 2026-07-23.
• Nothing else is tagged in the slice we track ourselves, so read this as a sample of one against a 155-game catalogue, not a map of it.

Collection mechanics as a category work differently from a standard payline game. Instead of every win being settled line by line and cleared, certain symbols are gathered into a collector or a meter, and value builds across spins until a threshold is reached and something pays out or upgrades.

The practical effect is that a spin which looks like a loss can still move you forward, because progress is being banked even when nothing lands in the balance. It also concentrates the payout at the moments those thresholds hit, which fits neatly with a catalogue that leans high volatility: long stretches of quiet accumulation, then a sharp move.

One thing to know before you go looking for it in Great Britain: feature buys are switched off across the GB market, so if you have seen a bonus buy button in a review or a video from elsewhere, it will not be on the build you play here. The feature has to be triggered in normal play, whatever the studio does elsewhere.

Three titles share the top of the published RTP range at 96.4%: Ho Ho Tower, Poltava and Wild Toro. Just behind them, five more sit at 96.3%: Diablo Reels, DJ Wild, Hidden, Hit it Hard and Ivanhoe.

What stands out is how tightly that top group is packed. All eight titles fall within 0.1 of a percentage point of each other, so the ceiling here is a band rather than a standout release, and even the best of them is only around 0.7 points above the field average of about 95.7%. If you are picking on RTP alone, any one of those eight is much the same choice.

On the current side, the one Elk Studios release our desk tracks with its own verified data is Pirots 5, released 2026-07-23 at 96.00% RTP and built on CollectR. That is above the catalogue median of 95%, though a single title cannot tell you which way the newer releases are trending.

Be honest about the scale of that slice: one tracked review against 155 games on file. The catalogue statistics on this page come from the data source, while the reviews come from the handful of releases we have actually sat down with.

Against the 80 studios we track, the numbers land like this:

• Catalogue size: 155 games, ranking 32 of the 80 studios we track, so comfortably in the upper half without being one of the volume houses.
• RTP: an average of 95.1% against a field average of about 95.7%, putting it 0.6 points below par.
• Volatility: high is the most common rating here, and 21 of the 53 rated studios lean very high, so a high-variance catalogue is normal across this field rather than a point of difference.

Read together, that is a mid-table studio on size, slightly under the field on returns, and squarely in the mainstream on variance. The RTP gap is the one number that goes against it, and it is small per spin but real across volume.

So the character of this catalogue is not a numbers edge. It is the build: a heavy Halloween and horror lean, classic fruit and animal themes kept alongside it, and collection-style feature design in the current work. If you want a steadier grind or the best available average return, other studios in our set do better on paper; if you want high-variance games with a dark seasonal streak, this is a fit.

A free demo is the safest way to meet an Elk Studios slot for the first time. It is the same game rather than a cut-down trailer version: the same reels, the same maths, the same features and the same paytable, running on play money, so you can watch how often a feature actually turns up and how the game paces itself between them.

What a demo cannot show you is how the game behaves with your own money over a real session, and with about four in five rated titles here at high or very high volatility that gap is wider than usual. A few hundred play-money spins can flatter a game or bury it purely by luck, and a balance that costs nothing teaches you nothing about your own stake sizing or when you would stop. Demos in Great Britain are 18+, and sites will ask you to confirm your age or sign in before the game loads.

Modern slots are built mobile-first and scaled up to the desktop, not the other way round, so a phone in portrait is the layout these games were designed around. The demos run straight in the browser, so there is no app to install and nothing to download.

The UK rules apply on a phone exactly as they do on a desktop, because they are tied to the Great Britain build of the game rather than to the device you open it on. That means a minimum of 2.5 seconds per spin, no autoplay, and the stake caps in force, whether you are playing on a laptop or on the train.

The catalogue statistics on this page come from the Elk Studios listing on our data source, and each figure is computed only from the titles that actually publish it. That is 155 games in total, 115 with a dated release, 94 with a published RTP and 91 with a volatility rating, so the RTP figures describe those 94 titles rather than the whole catalogue, and the volatility split describes those 91. We do not carry a catalogue max win because the source is not reliable on that field.

The reviews are separate. They come from the individual releases our desk sits down and plays, which today is a small current slice of the catalogue, so nothing here should be read as a claim that we have played all 155 games. Where a published figure changes at the source, or where playing a game tells us something the listing did not, we change what is on this page rather than defend the old number.
