What the top-round stake multiple measures, and what it ignores
This table sorts slots by a single figure: the official maximum win, stated as a stake multiple. If a studio states 100,000×, one round at a 0.10 EUR stake could in theory pay 10,000 EUR. A higher ceiling means a higher place; when ceilings are equal, alphabetical order decides. That is why the five games at 100,000× run from Double Fortune to Treasures of Aztec.
The maximum win is the limit the game’s maths allows. It is neither a typical result nor a target the game works towards over time. Most players never see it once in a lifetime, and studios don’t publish how often it happens.
The key says nothing about return, hit frequency or how long a budget lasts.
Every ceiling comes from the studio’s official site, as of 12 October 2026. A game made the table only if we found it in the Dukat.bet lobby on that day. Jackpot slots are left out, because rule 2.15 of the bonus terms excludes them from wagering.

The Source column refers to the sorting figure. For RTP and volatility we write “not published” wherever the studio left the field empty.
Where each of the ten ceilings comes from
1. Money Train 4
Relax Gaming launched it globally on 20 September 2023 and its press release calls it a high-volatility game. The game page lists only an alternative UK version, so we leave RTP as not published. Bonus Buy exists “in some jurisdictions”, and the studio gives no price.
2. Double Fortune
PG Soft rates it High on its own three-step scale (Low/Medium/High). The studio gives the 100,000× ceiling as “Max exposure” – a theoretical upper limit. PG Soft offers no bonus purchase at all.
3. Judgement Day Megaways
Megaways changes the number of symbols per reel on every spin. Red Tiger publishes a numeric index of 41.33 without a verbal scale, so we don’t translate it into “High” or “Extreme”. Released 14 September 2023.
4. Lucky Neko
The second of the PG Soft trio, with 96.73% RTP and medium volatility according to the studio. In the lobby it carries the Nodemoplay label, so don’t expect a demo (the same goes for Double Fortune and Treasures of Aztec).
5. Mahjong Wins Super Scatter
According to Pragmatic Play, the 100,000× ceiling is tied to four Super Scatters at once – a specific and very rare combination. It came out in May 2025.
6. Treasures of Aztec
Medium volatility and 96.71% RTP. It sits sixth purely because of the letter T; its ceiling matches the four games above it.
7. Gates of Olympus Super Scatter
The RTP field on the game page is blank. Again, the 50,000× ceiling depends on four Super Scatters. Released in April 2025.
8. Sweet Bonanza Super Scatter
The same ceiling as the previous title, but with a stated RTP of 96.51%. Gates of Olympus Super Scatter is ahead of it only alphabetically.
9. Ragnarok 40K
Slotmill lists two RTP versions (96.07% and 94.00%) and Very High volatility. Which version runs on Dukat.bet is shown in the game rules. Released 20 May 2025.
10. Big Gains
Red Tiger, 17 July 2025, ceiling 39,375×. Feature Buy is marked as available on the studio page, but no price is given – which is why the game is missing from the table sorted by purchase price.
Games with a ceiling that did not make the table
Some titles have the same or a higher ceiling yet stayed outside the ten. There are three reasons.
- Repetition across the network. Money Train 3 (100,000×), Astronaut (Red Tiger, 48,000×) and Gods of Troy Megaways (43,200×) would fit here, but they already appear in other tables. One title shouldn’t take up space in every list.
- No more than three games per studio. PG Soft also has Ganesha Fortune, Caishen Wins and Mahjong Ways 2 at 100,000×. Pragmatic Play would add Sugar Rush Super Scatter and Starlight Princess Super Scatter (both 50,000×). Without the cap, two studios would fill the table.
- Unclear lobby status. Search shows dozens of Nolimit City titles, yet the provider list reports just one game. Until that is cleared up, Nolimit City stays out.
Waiting in reserve are Trillionaire Megaways (35,841×) and Egypt Megaways (34,104×) from Red Tiger. Emberfall 40k from Slotmill is in the lobby, but its official game page returned a 404 error – and without a source, nothing goes into the table.
Starburst XXXtreme: 16,800× or 200,000×?
NetEnt is absent from the table because of conflicting numbers. Review sites keep repeating a 200,000× ceiling for Starburst XXXtreme. The official netent.com page, however, says “Max Win 16 800 x bet”. Similarly, aggregators give Dead or Alive 2 a 111,111× figure, while the studio states a maximum payout of 1,600.
The lesson is simple: a number lifted from a review may not match what the maker says. When two sources differ more than tenfold, the game stays out of a ceiling ranking until the conflict is resolved. How we handle such cases in general is set out in our methodology.
Why the ceiling tells you nothing about your odds
The ceiling is the edge of the outcome distribution, not its middle. PG Soft explicitly calls it “exposure” – the amount the studio accepts as the worst case for the operator. It does not describe a normal session.
A high ceiling also tends to go hand in hand with high volatility: the game has to save somewhere to afford one giant payout. It saves on smaller wins and on long stretches without any. Why the volatility scales of different studios can’t be compared directly is explained in our column-by-column guide.
There is a second limit to add. A casino may set its own cash cap on winnings per round or per day in its terms, and that applies before the studio’s multiple does.
Model calculation with invented amounts – not Dukat.bet data:
You play at 0.20 EUR per round. With a 100,000× ceiling, one round could in theory pay 20,000 EUR; with 40,000×, 8,000 EUR. If an invented casino had a cash cap of 10,000 EUR per round, the first game would pay you the same 10,000 EUR as a game with 50,000×. At this stake the difference in the table would vanish completely – and most rounds never come close to either figure.
So a position in the table is not advice on what to play.
Slots bonus and the rules for high-ceiling games
Slot machines fall under the Dukat.bet offer Slots Bonus – 500% up to 3,000 EUR + 15% Cashback. Under rule 2.14 of the general terms, the slots in this ten count 100% towards wagering. Rule 2.7, however, keeps a default maximum bet of 5 EUR during wagering – gamble features and bought bonus rounds included.
Rule 2.15 excludes a long list of games and all jackpot slots; make sure your title isn’t on it. You can also decline the offer (2.12). What is worth going through before your first round is summed up in the pre-play checklist.
You may play only from the age of 18, and only with money you have set aside for entertainment in advance.
