Eight games, examined one at a time
Updated: September 2026
This section is not an inventory of the whole Richroyal lobby. It is a shortlist of eight titles that the editors follow with a dedicated page each, and the point of a shortlist is depth: what the studio publishes, what only third-party catalogues claim, and what nobody has published at all. Seven of the eight spin reels or a grid. The eighth, Avia Rush, is a crash title from Evoplay that the lobby and the wagering rules book alongside the slot category. Every figure below is attributed, and where a source is missing the entry says so rather than filling the space.
The shortlist side by side
| Game | Studio | Format | RTP | Stake per round |
|---|---|---|---|---|
| Hell Hot 100 | Endorphina | 5x4, 100 fixed lines | 96.07 % | 1 to 200 euro |
| In Jazz | Endorphina | 5x3, 25 adjustable lines | 96.06 % | 0.25 to 200 euro |
| Jolly Santa | Endorphina | 3x3, five lines, four jackpot tiers | 96.06 % | 0.50 to 100 euro |
| Lucky Streak 3 | Endorphina | 3x3, five lines, no free spins | 96.01 % | 0.05 to 200 euro |
| Avia Rush | Evoplay | crash round, no reels | 96.00 % | not published |
| Sweet Dream Bonanza Claw 2000 | Clawbuster | 6x5 cascades, no paylines | 95.00 % | 0.10 to 25 units |
| Zeus 9 Claws | Clawbuster | 3x3 hold and win | around 95 % | sources unreliable |
| Wealth Of The East | Ela Games | 5x3, ten lines, fixed jackpots | 93.97 % | 0.10 to 20 units |
Read the right-hand column downwards and the spread is just over two percentage points, from Hell Hot 100 at the top to Wealth Of The East at the bottom. Across one evening that difference is invisible; across ten thousand rounds it is the most consequential number on this page.
Four studios, four ways of building a game
Endorphina: lines, paytables and a gamble ladder
Half the shortlist comes from one studio, and Endorphina builds to a recognisable pattern — declared paylines, a compact symbol set, a colour-guess gamble after paid wins, and full public documentation of return, volatility and stake range. Within that pattern the four titles could hardly be more different. Hell Hot 100 spreads a hundred fixed lines across twenty positions and starts at a full euro. In Jazz is the only one with a genuine free-spin round, complete with multiplier jokers. Jolly Santa squeezes a coin bonus and four jackpot tiers into nine cells. Lucky Streak 3 goes the other way entirely: low volatility, no scatter, no bonus, and spins from five cents.
Clawbuster: grids, cascades and thin documentation
Two titles come from Clawbuster, a much younger studio, and the difference in transparency is the story. Sweet Dream Bonanza Claw 2000 abandons paylines altogether for symbol counts on a cascading six-by-five field, and carries a name that leads a great many players to attribute it to a far larger developer. Zeus 9 Claws has the thinnest evidence base of anything in this section, which is exactly why its page is written as an evidence review rather than as a description.
Ela Games and Evoplay: the outliers
Wealth Of The East is the newest and busiest title here — coins that lock, a twenty-sided dice that prices them, an upgrade that can uncover fixed jackpots and a feature buy that skips the wait — and it charges for that complexity with the lowest return in the group. Avia Rush is the only title with no reels at all: a multiplier climbs until it stops, and the whole game is the decision of when to leave.
How this shortlist was checked
Each page was written from the studio product page wherever one exists, because that is the party that wrote the mathematics and it is the only source with a reason to be exact. Endorphina and Evoplay publish for their titles; Clawbuster does not list every game it makes, and Ela Games is documented mainly through catalogues. Where only catalogues were available, the entries were compared against each other and the disagreements were left visible instead of averaged away — Zeus 9 Claws differs between sources in the second decimal of its return, and Lucky Streak 3 has a third-party paytable figure that contradicts the studio outright. Where nothing was published, nothing was written: no invented volatility rating, no borrowed maximum win. A gap in a table is information too.
What fairness claims are worth, and what to read instead
Every lobby in this industry says its games are fair and its generators certified. The claim is close to meaningless on its own, because it describes an industry baseline rather than a distinguishing feature, and because the party making it is the one being assessed. Two things are checkable instead. The first is the return to player in the information panel of the running game, which describes the build actually loaded and not the version a catalogue happened to index. The second is the volatility rating in the same panel, which tells you how that return is distributed — rarely and large, or often and small. Those two numbers, read together, describe a game more honestly than any badge in a page footer. The wider argument is on the slots page.
Bonus funds across these eight titles
The promotional arithmetic is identical everywhere on this platform: 40 times the bonus amount in turnover, 14 days to complete it, a 20 euro qualifying deposit and a maximum stake of 5 euro per round while a bonus is open. Slots contribute 100 percent, table and live tables 10 percent, video poker nothing. Two traps apply specifically to this shortlist. On titles with a feature buy the purchase price is normally treated as one stake and will exceed the 5 euro cap. On titles with adjustable lines the cap is measured against the total bet, not the stake per line. The terms are on the wagering page, the free-spin treatment on the free spins page, and the cashier limits on the payments page.
The German rules and how much of them reach this platform
German law permits virtual slot machines nationwide but on narrow terms: 1 euro maximum per spin, five seconds minimum between spins, no autoplay, no jackpots, a panic button that locks the account for 24 hours, and a shared deposit ceiling of 1,000 euro per month enforced through LUGAS. Richroyal does not appear on the whitelist published by the Gemeinsame Glücksspielbehörde der Länder and holds a licence from another EU jurisdiction, so none of those provisions bind here, an OASIS exclusion has no effect, and the 5.3 percent stake tax is not remitted. Applied to this shortlist the consequence is concrete: at least four of the eight titles could not be licensed in Germany as they stand, whether because of jackpot tiers, a feature buy, or a game category that German law does not recognise at all. The controls that do exist belong to the account and are listed on the self-exclusion page, with the reasoning on the responsible gambling page.
What the game catalogue is made of
The lobby sorts into a handful of working groups. Slots supply most of the title count, from three-reel classics to modern grids with cascades and purchasable bonus rounds. Software table games rerun the same rules without a dealer and at whatever pace suits the player, while hosted tables are streamed from a studio with a person dealing on camera. Crash and instant titles form the fastest group of all: one decision per round, often resolved in seconds. The grouping is more than housekeeping, because promotional contribution is attached to it — slots count in full towards a turnover requirement, tables only a tenth, video poker not at all.
Behind the groups sit the studios. Software is not written by the casino; it is licensed from developers who build the mathematics and publish the return. That is why a given title behaves identically wherever it appears, and why the provider list says more about a catalogue than the headline game count does. It also explains why documentation quality varies so sharply: an established studio maintains product pages with return, volatility and stake range, while a newer one may leave only second-hand catalogue entries behind.
The studios behind these eight titles
Four developers divide the shortlist. Endorphina supplies four of the eight and is the best documented of them, publishing return, volatility, stake range and full paytables for each title. Clawbuster contributes two grid games but does not list every release on its own site, so the figures for Sweet Dream Bonanza Claw 2000 and Zeus 9 Claws come from catalogues rather than from the developer. Ela Games provides the most feature-dense machine in the group with Wealth Of The East, and Evoplay the only crash format with Avia Rush. Each individual page names which source stands behind which number.
