Coming soon. 3 Jewelling Diamonds is announced for 19 Aug 2026, but Iron Dog Studio has not published its RTP, volatility, max win or features yet. What follows is grounded in the studio's track record, not this game's own specs, and we update the page with the real numbers and a tested review the moment they land.
What works
- Iron Dog Studio has a catalogue of roughly 179 titles, giving it a substantial body of work and a clear track record to draw on.
- The studio's median RTP across 64 catalogue titles that publish one is 95.3%, sitting above many peers.
- A fixed release date of 19 August 2026 means the wait is short and defined, not open-ended.
- A free demo goes live on launch day, so you can test the game before staking real money.
What does not
- No specs have been published for 3 Jewelling Diamonds yet: RTP, volatility, max win, mechanic and features are all still to come.
- Without a live release, our desk cannot run a real-money session, so no tested review is possible before launch.
- This game is not confirmed to follow the studio's typical numbers; catalogue patterns are context, not guarantees.
- The studio's catalogue leans heavily towards very-high volatility, which may not suit every playing style, and this game's own volatility is unconfirmed.
01
What 3 Jewelling Diamonds is and when it lands
3 Jewelling Diamonds is a newly announced slot from Iron Dog Studio, a Brighton-based developer founded in 2017. It is due to release on 19 August 2026, placing it roughly two weeks from the time of writing. The studio has not yet published any specs for this game: no RTP, volatility rating, max win, mechanic, theme or feature set has been confirmed.
This page does not attempt to describe how 3 Jewelling Diamonds plays, because that information is not yet available. What we can do is set out Iron Dog Studio's real catalogue record so you have an honest sense of what releasing with this studio has typically looked like.
3 Jewelling Diamonds releases on 19 August 2026, and its full spec sheet is still to come.
02
What to expect from an Iron Dog Studio release
Iron Dog Studio has built a substantial catalogue since launching in Brighton in 2017. Here is what its record shows across its releases:
- Catalogue size: roughly 179 titles in total, with 105 carrying a confirmed release date.
- Typical RTP: across 64 studio titles that publish one, the median sits at 95.3% and the average at 95.42%, ranging from 93% to 96.7% across the catalogue.
- Volatility lean: of 58 rated titles on the studio's 1-5 ladder, 44 are rated very high and 11 high - the studio's output skews heavily towards the top end.
- Common mechanics: Megaways appears in 34 catalogue titles; the studio also carries 2 progressive or jackpot-linked releases on record.
- Common themes across the catalogue: animal (14 titles), Christmas (11), pig (6), fruit (6), Halloween (5) and diamond (4).
3 Jewelling Diamonds is not confirmed to match any of these catalogue patterns. The studio has not stated this game's volatility, RTP or mechanic, and its real spec sheet may land anywhere across the studio's historical range. Treat these figures as context for Iron Dog Studio's body of work, not as predictions for this specific release.
03
How to play 3 Jewelling Diamonds on release

What we will add on release
Once 3 Jewelling Diamonds is live and Iron Dog Studio has published its spec sheet, we will update this page with the following:
- The studio's published specs for this game specifically: RTP, volatility rating, max win, mechanic and feature set.
- The playable free demo, embedded here so you can try it without leaving the page.
- Our tested review, written after a real-money session at the desk - no verdict is possible before we have played it.

How we build this pageOUR METHOD
- We take the specs from the studio's own release sheet and the game's paytable, never from a sister title or a guess. Every RTP, max win, volatility and feature on this page is checked against that source before it goes live.
- The demo above is the supplier's real GB build, loaded straight from their server, so what you play is what launches. When a game is out, the desk plays a session before we add a tested review, a measured hit rate and a score.
- The page is compiled with our own tooling to keep every release current and consistent, then published under the byline of the reviewer above, who owns its accuracy and any corrections. We change the date when the facts change, not to look fresh.
- Spotted something out of date? Every page shows the day we last checked it. Tell us and we will fix it and log the change.
