In Jazz at Richroyal

Updated: September 2026

In Jazz by Endorphina, set in a 1930s Chicago jazz club with a treble clef wild

In Jazz drops a slot machine into a Chicago club of the 1930s: a double bass, a trumpet, a gramophone and a treble clef doing the work of the wild. Endorphina kept the frame deliberately old-fashioned — five reels, three rows, 25 paylines that the player can still adjust, a feature almost extinct in newer releases. This guide covers the layout, the free-game round where the title makes its money, and what the stake range looks like from a German reader point of view.

Layout, and where the value actually sits

Five reels, three rows, 25 lines. Endorphina puts the return to player at 96.06 percent and the volatility at medium to high, and the paytable explains that rating without any need for guesswork. The best regular symbol returns 32 times the total bet for a full line of five. The scatter returns 200 times for five. A gap of that size tells you where the mathematics has parked the money: not in the base game, but in the round the scatter opens. Playing In Jazz means funding a wait. The adjustable line count is the tool that makes the wait affordable, since dropping lines lowers the cost per spin — at the price of fewer ways to connect.

The clef, the scatter and the jokers

The treble clef is the wild and substitutes for everything except the scatter. The scatter carries the game logo, pays from any position and opens ten free games. Inside that round the jokers do the interesting work: each one rates the line win it lands on at one, two or three times its value. Ten spins is a short window, so the character of the round is decided by a handful of joker draws — a three-times joker on a well-populated line is the moment the whole design is aiming at, and its rarity is precisely why the volatility rating is not low.

After a paid base-game win the familiar Endorphina gamble is available: double the amount on a colour call, lose it on a wrong one. Endorphina also lists a feature called Bonus Pop in the specification for this title. How it behaves in the build a given operator has loaded, and whether it has been enabled there at all, is not determined by the studio sheet but by the integration — the game rules panel is the place to check.

Stakes, cashier and bonus funds

The range runs from 0.25 to 200 euro per spin, and the low entry point is what makes this title one of the more patient options in the section: a quarter-euro spin lets a bankroll survive long enough to reach the free games more than once. The account is in euro, so a card, a bank account or an e-wallet involves no conversion. Deposits begin at 10 euro, 15 euro via SEPA and about 25 euro in crypto; withdrawals start at 15 euro, cap at 4,000 euro per week and transfer within three hours of approval. The routes are compared on the payments page and the deposit sequence on the how to deposit page.

With bonus funds the platform applies 40 times turnover in 14 days, a 20 euro qualifying deposit and a 5 euro maximum stake per round, with slots contributing 100 percent. On a game with adjustable lines there is a trap worth naming: the 5 euro limit is measured against the total bet shown on the panel, not against the stake per line. Reducing lines lowers the total and buys headroom; raising them can breach the cap without the per-line figure changing at all. The terms are on the wagering page.

Demo play, and the German comparison

A play-money build with identical mathematics exists for the title. Use it to see how far apart two free-game rounds can land depending on which jokers appear; that variance is the entire personality of the game. It tells you nothing about the next session, since every spin is independent.

A German-licensed slot may not take more than 1 euro per spin, must leave five seconds between spins and may not offer autoplay or a jackpot. Richroyal is absent from the whitelist of the Gemeinsame Glücksspielbehörde der Länder and holds a licence from another EU jurisdiction, so none of those constraints operate here, nor does the LUGAS ceiling of 1,000 euro of deposits per month across licensed German sites, nor an OASIS exclusion, nor the 5.3 percent stake tax. In their place stand the deposit limit, loss limit, time-out and account closure listed on the self-exclusion page, with the broader discussion on the responsible gambling page. This portal is independent, offers no games and is written for adults aged 18 and over.

How do the multiplier jokers in In Jazz work?
They appear during the ten free games and rate the line win they touch at one, two or three times its value. The round is short, so the difference between a session of ones and a session that lands a three is considerable.
Can the number of paylines be changed?
Yes, and that is unusual for a modern release. In Jazz runs 25 lines across a five by three grid and lets the player reduce them, which lowers the cost of a spin and the number of ways to hit at the same time.
What is the highest paying symbol in In Jazz?
Among the regular symbols the top one returns 32 times the total bet for five of a kind. The scatter pays far more at 200 times for five, which is why the free games matter more than any single base-game line.
What is the RTP and volatility of In Jazz?
Endorphina states 96.06 percent and rates the volatility medium to high. Both figures are repeated in the information panel of the running game, and only that panel describes the build actually loaded at an operator.
Is a maximum win published for In Jazz?
No, and we do not borrow a number from elsewhere. If a ceiling applies to the version you are playing, it will be stated in the game rules, reachable from the menu inside the game window.
