Onlyplay
slots

Onlyplay was founded in 2020. We do not hold a head office location for the studio, so we are not going to name one, and we would rather leave a gap on the page than fill it with a guess.

On our data source the catalogue runs to 170 games, of which 90 carry a dated release. The dated slice starts on 21 March 2024 and runs to 20 August 2026, so it covers the studio's recent output rather than its full history back to 2020.

Within that dated window the pace steps up sharply. The feed holds 18 titles dated 2024, 44 dated 2025 and 28 dated 2026, which is a studio shipping at a steady weekly-ish clip rather than saving everything for a handful of flagship launches.

The theme tags across the catalogue tell you what the release schedule is built around:

• Fruit: 22 titles, sitting at the top of the list
• Christmas: 15 titles
• Halloween: 9 titles
• Animal: 7 titles
• Sports: 5 titles
• Coin: 5 titles

Christmas and Halloween together account for 24 titles, so a meaningful slice of the output is seasonal and built to be swapped in and out of a lobby at a fixed point in the year. The fruit block on top of that points at classic-style machines rather than heavy narrative themes.

34 of the 170 games on our data source publish an RTP figure. Across those the median is 95.5%, the average is 95.8% and the full range runs from 95% to 97%.

The gap between median and average is worth a second of your time. The mean sits above the midpoint because a cluster of titles is pinned at 97%, which drags the average up while the typical Onlyplay slot still lands at 95.5%. Read the median as the number you are most likely to meet.

Against the field, the studios we track average about 95.7%, so Onlyplay's 95.8% is marginally above it. The 95% to 97% range is also narrow, two points wide end to end, so there is no bargain-basement outlier hiding at the bottom of the list.

Volatility is rated on 33 titles on the 1 to 5 ladder, and the distribution is a barbell rather than a curve:

• Very high: 21 titles, the most common rating by a distance
• Medium: 12 titles
• Low, low to medium and high: 0 titles between them

That empty middle is the useful finding. Onlyplay is not building a gentle ladder from calm to spicy; it is building medium games and very high games, with nothing rated in the bands either side. If you want a slow-burn session you are choosing from the 12, not browsing the whole shelf.

One practical caveat on any RTP figure. Slots are frequently shipped in more than one RTP configuration and the operator picks which one runs on its site, so the number live at your casino can sit below the headline figure quoted anywhere, including here. Check the paytable inside the game itself before you spin, because that is the only copy that reflects the build you are actually playing.

Across the Onlyplay releases we track and have verified ourselves, these are the mechanics on the board:

• Respins
• Hold and Win
• Megaways: 8 titles in the catalogue on our data source

Hold and Win is the familiar coin-collection format where landing symbols lock in place and reset a spin counter, and it pairs naturally with the very high volatility ratings that dominate the catalogue. Respins do similar work on a smaller scale, extending a near-miss rather than opening a full bonus round.

The 8 Megaways titles are a small slice of a 170-game catalogue, so treat the licensed reel engine as an occasional line rather than the studio's default shape.

If you are playing from Great Britain, note that a feature buy is not offered here. Where a game carries a bonus-buy option elsewhere, it is switched off on GB-facing sites, so you reach the bonus round by landing it in normal play.

Five titles share the top of the RTP table on our data source at 97%: CosmoX, CricX, Fruit Train Express Hold & Win, GoalX and Rush For Diamonds. Three of those carry the X suffix and one is a Hold & Win build, so the highest-RTP corner of the catalogue is not a single one-off release but a small recurring family.

Below that sit Cherry Boom Xmas Edition and Wolf Treasure on 96.6%, and Caramelo Jackpot on 96.14%. Cherry Boom Xmas Edition is a good illustration of the seasonal pattern in the theme tags: a festive re-skin of an existing fruit machine rather than a fresh build.

On the review side we have verified data for two recent releases. Hot & Spicy: Chili Rush arrived on 22 July 2026 with an RTP of 96.58% and a Respins feature, and 3 Fortune Cups landed on 16 July 2026 at 96.04% with Hold and Win. Both sit above the catalogue median, though two titles is a small slice of 170 and we would not read a trend into it yet.

Set against the 80 studios we track, Onlyplay lands as follows:

• Catalogue size: 170 games, ranking 27 of the 80 studios we track, so upper third for output without being at the top of the pile.
• RTP: an average of 95.8% against a field average of about 95.7%, which is above the field but by a fraction rather than a margin worth chasing.
• Volatility: the very high lean is common rather than distinctive, with 21 of the 53 studios we track leaning the same way.
• Release pace: 44 dated titles in 2025 and 28 in 2026 on the feed, which is a high-frequency schedule rather than a slow drip of flagship launches.

The honest summary is a studio that separates itself on volume and on that empty middle in the volatility ladder, not on RTP. A tenth of a point above the field average is inside the noise, and it is not a reason to pick one studio over another.

We are demo-first on every review. A demo is the real game running on play-money credits, with the same reels, the same paytable and the same features as the cash version, so you can learn how a Hold and Win round behaves before any of your own money is on the line.

That matters more than usual with a catalogue this weighted towards very high volatility. Long dry spells are the intended shape of those games, and a demo is the cheapest way to find out whether that pace suits you.

Demos in Great Britain sit behind an 18+ age gate, so you will be asked to confirm your age before a game loads. Play-money wins are not withdrawable and never convert to cash.

The catalogue statistics on this page are computed from the Onlyplay titles on our data source, and each figure only counts the games that actually publish it. That is why the sample sizes differ: 170 games in the catalogue, 90 with a dated release, 34 publishing an RTP and 33 carrying a volatility rating.

The reviews are a separate and much smaller thing. They come from the individual releases the desk plays, which today is a current slice of recent titles rather than the full 170. We do not claim to have played the whole catalogue and we are not going to write as though we have.

When the underlying data changes, the numbers here change with it. New releases move the release counts, newly published RTPs move the median and the average, and we would rather correct a figure than leave a tidy but stale one on the page.
