Two conditions a game must meet to enter a table
First, the game must be in the Dukat.bet lobby on the date shown by the table. A studio release or coverage elsewhere is not enough. We check the lobby directly and date every ranking – currently as of 12 October 2026.
Second, the sorting figure must be public. If the key is the max win, the studio has to publish it – on its site, in the game rules, or at least so that two independent sources agree. Without it, a game stays out, even if it fills the lobby’s first screen.
These two filters remove more titles than you might expect. Some makers don’t publish certain figures (Novomatic, for instance, with RTP), so their games are absent from the RTP ranking. That is no verdict on the game – there is simply nothing to compare.
No game ever gets a place on a figure we would have to guess.
Four levels of trust in a single figure
Each figure carries a source type. We go top down and drop a level only when the one above is missing:
- Studio’s official site – a product sheet, release announcement or game page on the maker’s website.
- Game rules – the info window inside the game, where the maker lists the return, the win cap or the feature price.
- Two independent sources – two unrelated databases or reviews with the same value. One source never suffices, however well known.
- Not published – no studio figure and the sources disagree. We then write exactly that, not an estimate.
In the “Source” column you will therefore see one of three labels: studio’s official site, 2 independent sources or not published. Game rules count as an official source, since the maker writes them.
When two official figures differ – common with games shipped in several RTP versions – we list the one the studio calls standard and note the gap below the table.
One sort per table, alphabet on a tie
Each ranking has one key, shown in the page header: RTP, max win, release date, bonus-buy price. Numbers run from highest, dates from newest. Other columns don’t affect the order; they are for reading only.
Why not a combined score? Because the weights would be invented. Give RTP one weight and volatility another, and the result is only as reliable as those weights – not at all. One key takes a minute to check; a weighted mix doesn’t.
On a tie, the game title decides alphabetically: the name that comes first sits higher. The position then says nothing about quality, only about spelling.
It sounds dry. That is exactly why it can be verified.
Who stays out even when the lobby shows them
Some games are left out on purpose. Jackpot slots are skipped where their progressive part would distort the key: their top win depends on the pot, not the rules. Point 2.15 of the general Dukat.bet bonus terms also excludes them from wagering, which we flag where it matters in practice.
The second filter is duplication. One game with a high RTP, a big cap and a bonus buy could appear in four rankings at once. We limit repeats so each table shows a partly different slice of the catalogue. Every page lists rejected candidates with the reason.
The third filter is lobby labels. Tabs like “High RTP” or “Jackpot” are not data, because they don’t deliver what they promise: “High RTP” actually groups games with “Hot” in the title, and titles with no jackpot carry the jackpot tag. How to handle this when reading figures is in the guide how to read the table columns.
The whole process in seven rows
| Step | What we do | What it does not imply |
|---|---|---|
| 1. Lobby check | Check that Dukat.bet lists the game in its lobby on the table date | That it will still be there in a month |
| 2. Finding the figure | Look for the key value at the studio, then in the game rules | That the casino runs the same version as the studio |
| 3. Second source | Without an official figure, look for two matching values | That the figure won’t change in the next game version |
| 4. Sorting | Order by one key, alphabetically on a tie | That first place is the best fit for you |
| 5. Exclusion | Leave out jackpot titles where they distort the key, and limit duplicates | That an excluded game is worse |
| 6. Date | Attach a status to each table, for example as of 12 October 2026 | That everything holds unchanged after that day |
| 7. Correction | Verify a reported error and update the table | That errors never happen |
The third column matters as much as the second. Each step settles something and leaves something open – and the open part often matters more to a player.
What we never let into the order
Stars and points. “8.7 out of 10” looks precise, yet nobody can verify it – it is someone’s impression. So dukat888.win has no stars and no editorial percentage scores.
Reader votes. Polls are easy to sway and measure popularity, not a game property. Popularity also moves faster than we could rewrite a table.
Paid positions. No studio or casino can buy a higher spot. The key sets the order, and the key is not for sale.
“Feel of the game”. Graphics, music or the first spins are fair reasons to pick something, but they can’t be measured equally for everyone, so they stay out of the order.
A ranking position is not an invitation to play, just the result of a sort. How to pick from it for yourself is covered in the checklist Before your first game.
When you spot a figure that doesn’t add up
Figures age. A studio ships a new version, a casino changes its setup, a game quietly leaves the lobby. If you notice this, write via the contact page – game name, ranking page and what looks off are enough.
We recheck it the same way the table was built: official source, then game rules, then two independent sources. If the error holds, we fix the table and its status date. If not, the figure stays, but we review the source again.
How much data each studio actually publishes is shown in the studio ranking.
