Slot Summary

In Jazz occupies the narrow space between a conventional line slot and a period music piece, using a 1930s Chicago club as more than background. Endorphina ties its 25-line format to a Free Spins round where three featured musicians carry different win multipliers. The treble-clef Wild and logo Scatter keep the base game familiar, but the musician roles give the bonus its own identity.

How It Plays

Wins form from left to right across 25 paylines on the 5x3 layout. The base loop remains direct, with Wild substitution and a separate Gamble option after eligible results.

The Scatter changes the pace by moving play into Free Spins. There, the three musician symbols stop being simple character artwork and apply distinct multipliers to completed wins.

Theme & Atmosphere

Music and Retro cues define a 1930s Chicago jazz club, with the singer, saxophone player, and double bassist serving as both performers and functional symbols.

The Party theme is restrained by the intimate club setting. Instruments and period performers carry the atmosphere instead of turning the subject into a modern concert scene.

Features & Win Potential

The Wild supports ordinary payline combinations, while the Scatter pays independently and opens Free Spins when enough copies appear anywhere across the reels.

Multiplier values are assigned to the three musician symbols during Free Spins. The round can retrigger if another qualifying set of Scatter symbols lands.

Bonus & Free Spins

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (96.00%), with wins capped at its top multiplier (1,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
