Coming soon. Lucky Stamps is announced for 17 Sep 2026, but Endorphina 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. The desk plays it from launch day and the real numbers replace this the moment the studio publishes them.
What works
- Fixed release date of 17 September 2026 confirmed, giving a clear timeline to plan around.
- Endorphina has a catalogue of around 231 games built since 2012, a long and assessable track record.
- The studio's median RTP across 21 published titles is 96.06%, one of the stronger catalogue averages in this space.
- Endorphina has been active in the UK market recently, with Gift of Midas released 30 July 2026.
What does not
- RTP, volatility, grid, paylines, mechanic, theme, features and stake range are all unpublished ahead of release.
- Lucky Stamps is not confirmed to follow the studio's typical numbers, so catalogue figures are context, not a prediction.
- Volatility data covers only 11 of the studio's roughly 231 titles, so this game's volatility could land anywhere on the scale.
- No mechanic or feature detail is on record, leaving the bonus structure and max win entirely unknown before release.
01
What Lucky Stamps is and when it lands
Lucky Stamps is a newly announced slot from Endorphina, a Malta-based studio that has been building casino games since 2012. With around 231 titles on its books and Gift of Midas reaching the UK market on 30 July 2026, Endorphina is an active publisher. Lucky Stamps is scheduled to reach UK-licensed casinos on 17 September 2026.
None of this game's own specs are on record ahead of release. RTP, volatility, grid size, paylines, mechanic, theme, features and stake range have not been published by the studio, and each will be added as they are confirmed. That is not a gap to smooth over; it is the honest position for any newly announced title whose spec sheet has not yet arrived. Until those details land, everything below draws on the studio's catalogue record.
Lucky Stamps arrives 17 September 2026, the only timing fact the studio has confirmed.
02
What to expect from an Endorphina release
Endorphina's catalogue gives a clear signal of what the studio has built across its output so far:
- Catalogue size: around 231 games released since 2012, with 49 carrying a confirmed release date.
- Typical RTP: across 21 titles that publish a figure, the studio's median sits at 96.06%, with a range from 93.77% to 98.07%.
- Volatility lean: of 11 rated titles, medium is the most common (4 titles), followed by very high (4) and high (3); no rated title in the set falls below medium.
- Mechanics on record: tumbling reels and bonus-buy features each appear in 2 titles across the catalogue, a small but present footprint.
- Top themes: fruit leads the studio's output (33 titles), with Halloween (17), horror (17), Christmas (13), Asian (11) and animal (10) also well represented.
Lucky Stamps is not confirmed to match any of these. Its own RTP, volatility, mechanic and theme are all unpublished, and the studio's catalogue numbers give context for the studio's typical range, not a forecast for this game.

How to play Lucky Stamps
A free play-money demo is a build of the real game running on virtual credit. It costs nothing: no deposit, no account, nothing staked. You see the real mechanics and feature triggers without any financial risk, which makes it a practical way to gauge whether a game's style suits you before putting real money in.
Real-money play is available only at UK-licensed casinos and only once the title has been released. On this site, released slots are played with real money at UK-licensed casinos; the published specs are checked against what appears on screen, and a person reads every article end to end before it goes live.

Lucky Stamps FAQ
When does Lucky Stamps come out?
Lucky Stamps is scheduled to reach UK-licensed casinos on 17 September 2026. That is the one timing fact Endorphina has confirmed for this title. The full spec sheet, covering RTP, grid, mechanic, features and stake range, will be added once the studio publishes those details.
What is Lucky Stamps's RTP or max win?

Across 21 titles in the studio's wider catalogue that do carry a published RTP, the median sits at 96.06% (range 93.77% to 98.07%), but Lucky Stamps is not confirmed to follow that.
Is the Lucky Stamps demo free?
A free play-money demo runs the real game on virtual credit, with no deposit and no account required. Nothing is staked, so there is no financial risk. It is a practical way to explore a game's mechanics and layout before deciding to play with real money at a UK-licensed casino.
What kind of games does Endorphina make?
Endorphina, founded in 2012 and based in Malta, has a catalogue of around 231 games. Fruit themes lead its output (33 titles), with Halloween, horror and Christmas themes also common. Of 11 volatility-rated titles, medium is the most frequent, and the studio's median RTP across 21 published titles stands at 96.06%.
How we build this pageOUR METHOD
- The desk plays what there is to play, with its own money. A released slot is played for real at a UK-licensed casino, and the demo above is the supplier's real GB build, loaded straight from their server, so what the desk opens is what launches. Either way, what it sees on screen is checked against the RTP, max win, volatility and features the studio has published. A game that is not out yet, with no demo to open, cannot be played, and its page says so.
- The article is then written up from those verified facts by our own tooling, which is what keeps every release on the site current and consistent. Specs come from the studio's own release sheet and the game's paytable, never from a sister title or a guess, and a number nobody has published is left blank rather than filled in.
- A person then reads every article end to end, for facts, structure and quality, and edits it where it is not up to standard. It publishes under the byline above, and that person 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.
