Endorphina takes players back to a time of neon lights, double basses, and the smoky air of a 1930s Chicago club in its release, In Jazz. This isn’t just another fruit machine with a different skin. It is a dedicated homage to the birth of the jazz age. The provider focuses on a specific atmosphere here, blending a rhythmic soundtrack with a math model that rewards patience. If you enjoy games where the audio is as important as the mechanics, this title stands out in a crowded market.
The gameplay centers on a 5-reel, 3-row structure. It feels traditional but carries the weight of modern high-fidelity production. Unlike many high-octane Megaways titles that bombard the senses, In Jazz maintains a steady, cool tempo. It invites you to sit down, pour a drink, and wait for the scatters to align. The real draw is the harmony between the Expanding Wild multipliers and the free games, which can turn a quiet session into a high-paying crescendo.

The RTP sits at exactly 96%. This is the industry baseline. It is fair but doesn’t offer a mathematical edge over the house. Expect periods of dry spins followed by significant clusters of wins. The volatility isn’t officially labeled, but in practice, it leans toward the higher side. Your bankroll needs to weather the quiet sections of the “song” to reach the bonus rounds where the real money lives.
✨ Theme, Graphics, and Soundtrack
The aesthetic is the strongest point of In Jazz. Endorphina opted for a sophisticated palette of deep blues, purples, and gold. The background features a dimly lit stage, setting the mood for a late-night performance. Symbols include the classic 10 through Ace card ranks, styled with musical flourishes. High-value symbols are represented by the band members: the suave double bass player, the saxophonist, and the elegant female vocalist.
The soundtrack is not a looping 10-second clip. It is a full-bodied jazz arrangement that evolves. When you land a win, the instruments emphasize the payout. The Treble Clef acts as the Wild, substituting for all symbols except the Scatter. It is the most frequent helper in the base game. The “In Jazz” logo is the Scatter, and landing three of these is your ticket to the main feature.
🎁 Bonus Features and Free Spins
The bonus mechanics in In Jazz are concentrated into one powerful feature. There are no convoluted pick-and-click games here. Everything flows through the free spins.
Jazz Band Free Spins
Landing three or more Scatter symbols triggers 10 free spins. During this round, the Jazz Band Joker feature becomes active. These are not standard wilds. Three different Joker symbols—each representing a band member—can appear on the reels.
Expanding Multiplier Wilds
The Joker symbols expand to cover the entire reel when they contribute to a win. Each member carries a specific multiplier:
- Double Bass Player: Grants a 2x multiplier on the win.
- Saxophonist: Grants a 3x multiplier on the win.
- Female Singer: Grants a 5x multiplier on the win.
If multiple Jokers land on the same spin, their values can create a massive payout. This is where the 25 paylines become lucrative. The feature can also be retriggered if you land another three scatters during the free spins, adding 10 more rounds to your total.
Risk Game (Gamble Feature)
Like most Endorphina slots, In Jazz includes the classic Card Risk Game. After any win, you can choose to gamble your profit. You are shown one dealer card and four facedown cards. If you pick a higher card, you double your win. You can do this up to 10 times. However, the average RTP of this specific gamble feature is 84%, so use it sparingly.
