Zillion Games
slots

Zillion Games was founded in 2021 and works out of Limassol. The oldest title on our file dates to 7 January 2021 and the newest to 30 July 2026, so the catalogue covers a little over five years of output.

There are 88 games on our data source, 85 of them with a dated release. That is a mid-table catalogue rather than a deep back library, and most of it has been built in the last three years.

Releases by year on the feed:

• 2021: 11 games
• 2022: 7 games
• 2023: 7 games
• 2024: 18 games
• 2025: 21 games
• 2026: 21 games so far

The pattern is a quiet middle period followed by a clear step up from 2024 onwards. On current pace the studio is shipping at roughly twice its early rate.

Themes across the catalogue skew to familiar slot furniture:

• Egyptian: 8 games
• Animal: 8 games
• Christmas: 7 games
• Fruit: 6 games
• Asian: 5 games
• Buffalo: 4 games

Only four Zillion Games titles publish an RTP on our data source, so treat these figures as a sample rather than a full picture. Across those four the median is 95.25% and the average is 95.48%, inside a narrow range of 95.2% to 96.2%.

The studios we track average about 95.7%, so 95.48% sits below the field. The gap is small in absolute terms, but it is the direction that matters over a long session.

Volatility is the more striking number. All four rated titles come in at very high, with nothing on the low, medium or high rungs of the 1-5 ladder. On that evidence the maths is built for long dry spells punctuated by rare big hits, not steady small returns.

One thing worth checking yourself: studios often ship the same slot in more than one RTP configuration, and the version a given casino runs is the casino's choice. Read the RTP in the game's own info screen rather than trusting a figure quoted elsewhere.

Across the Zillion Games titles we track and can link, the mechanic on record is Hold and Win: respin rounds where cash or jackpot symbols lock in place and reset the respin counter. Both Wolf's Moon 3 and Royal Crown Wheel use it.

That is a narrow slice of an 88-game catalogue, so it says what the desk has covered rather than what the studio does everywhere. We will add mechanics here as we play more of the range.

If you are playing from Great Britain, note that feature buys are switched off. Any bonus-buy button that appears in other markets will not be available to you, so bonus rounds have to be triggered in normal play.

Firestorm Joker is the highest RTP we have on file at 96.2%, and it is the only Zillion Games title we track that clears the field average. Golden Dragon Deluxe and Snow Wolf Saga both publish 95.25%, with Gems Sky just behind at 95.2%.

On the recent end, 3 Crown Coins is the newest release on our data source, dated 30 July 2026. Wolf's Moon 3 (26 July 2026) and Royal Crown Wheel (16 July 2026) both run Hold and Win at 95.20%, which gives a fair read on where the studio's current output sits.

Set against the 80 studios we track:

• Catalogue size ranks 46 of 80, so the library is mid-table rather than large.
• The 95.48% average RTP is below the field average of about 95.7%, on a sample of four titles.
• A very high volatility lean is common, not unusual: 21 of the 53 studios with volatility data on file lean the same way.

The short version is that Zillion Games looks typical of the high-variance end of the market, with an RTP sample that lands slightly on the wrong side of average.

We link a free demo wherever one exists. The demo is the real game running on play money, with the same reels, paytable and features, so it is the cheapest way to see how a very high volatility slot actually behaves.

Given the volatility ratings here, a demo run is worth the time. A few hundred spins on play money will tell you more about the pace of a Hold and Win title than any figure on a page.

An 18+ age check applies to demo play from Great Britain, and play-money results carry no cash value.

The catalogue statistics on this page are computed from the Zillion Games titles on our data source, and each figure only counts the games that actually publish it. That is why the RTP and volatility numbers rest on four titles while the catalogue count sits at 88.

The reviews are separate. Those come from the individual releases the desk sits down and plays, which is a small and current slice of the range. We do not claim to have played the whole catalogue, and we do not average what we have not seen.

When the underlying data changes, the numbers here change with it. New releases, newly published RTPs and corrected volatility ratings all feed straight back into this page.
