In Jazz

Endorphina's catalogue runs to 230 titles in our index, and In Jazz is one of the plainer entries in it. Five reels. Fixed paylines, no Megaways framework, no buy-in for the feature round, no cascading symbols and no shared jackpot pool. Our sources don't yet carry a theme tag for it, so the jazz-club framing comes from the name alone.

A 96.06% return carrying level-4 swings

That return figure, sourced from slot.report and still uncorroborated, lands two hundredths of a percentage point under the 96.08% midpoint we calculate from 9,226 games. Dead average, in other words. The volatility reading is what separates it: level 4 of 5, medium-to-high, which slot.report independently records as medium-high. Bets start at 0.01 and stop at 1, a narrow band that caps how much a poor run can cost.

Players who want variance without committing a big bankroll fit best. The 1-unit ceiling is genuinely low. No maximum win figure appears in our data, so we won't guess at one.

The operator's long-run edge on this title works out near 3.94%. Play with a session limit, and only if you are 18+.
