Overview
IN JAZZ is a classic 5x3, 25-line slot from Endorphina, built around a 1930s Chicago club theme. I get smoky backroom jazz, red curtains, instruments and stage performers rather than flashy mechanics. For chat, that means a straightforward session with one clear selling point, the bonus round and its musician jokers with multipliers.
From a streaming angle, I see this as a slower burner. The RTP is 96.06%, volatility is listed as Medium-High, and the bet range runs from 0.25 to 200. If I'm honest with viewers, the base game looks simple enough to follow, but the feature is where the slot gets its real personality.
Main symbols
Symbols are built around jazz instruments, card icons and three main character symbols. The key ones are the Treble Clef Wild and the In Jazz logo Scatter. Wins land on 25 adjustable paylines from the leftmost reel, so it plays like a proper old-school video slot rather than a modern ways game.
Payout-wise, the Scatter is the biggest single symbol result listed, paying 200x for five. Five Wilds pay 40x. Among the regulars, the singer is the top standard symbol at 32x for five of a kind, while the double bassist pays 24x. Decent enough, but not massive, so I would not expect the base game to carry a whole stream.

Free Spins Explained
Three or more Scatter symbols anywhere trigger 10 Free Games. That part is easy. What matters more is the Jazz Band Joker setup in the bonus. Every free spin gets two guaranteed musician jokers, and they work as expanding wilds while also applying a multiplier when they help make a win.
The saxophone player gives 1x, the double bassist gives 2x, and the singer gives 3x. Reviews also say the feature can re-trigger with three more Scatters during free spins. That is the bit I'd stream for, because guaranteed jokers each spin give the round a better pace than the base game, and chat can actually track what each musician adds.
Bonus Buy Options
Three or more Scatter symbols trigger 10 initial free spins. During the feature, musician jokers multiply wins by 1x, 2x or 3x, and the round can re-trigger with three more Scatters.
RTP: 96.06%
After a winning spin, winnings can be gambled against the dealer by choosing one of four face-down cards. A win doubles the prize and the gamble can continue up to 10 times.
An extra feature listed for the game, though availability may depend on jurisdiction and casino settings.
Classic Risk Game
After a winning spin, Classic Risk Game can let you gamble the prize by picking one of four face-down cards against the dealer's card. Beat it, and the win doubles. You can keep going up to 10 times, but one miss wipes the whole amount from that gamble round.
I don't mind that as a side option on stream, though it is not why I'd load IN JAZZ. There is also Bonus Pop listed as a feature, but availability may depend on jurisdiction. One thing to flag for viewers, one review mentions a bonus buy, but the core game details do not explain a cost, so I would not count on that being consistent.
