Introduction
Get ready for for a melodic extravaganza with In Jazz, Endorphina’s music-themedvideo offering that takes players back in time to an old school jazz club, with the slot played out across five reels and 25 adjustable paylines.
There are five themed symbols, plus the lower-value card symbols of 10 through to A. The musical symbol is the Wild, substituting for all symbols bar the scatter to help create winning combinations. The ‘In Jazz’ logo is the scatter, counting at any position on the reels.
Below the reels is a grey streamlined user interface showing options, lines, coin value and bet to the left, and turn, auto and main spin to the right. Game information and sound are to the top right above the reels.
Theme, Graphics & Soundtrack
Some say jazz was born back in 1895; other says it was 1917. The evolution of jazz went through Prohibition at the start of the 20th century, the emergence of gangster-run clubs, the Bebop of the 1940s, soul jazz and then a re-emergence of the 1970s free and fusion jazz trends.
The background is a grand jazz club with tables, chairs and people filling the balconies. It’s lit by hazy orange light, and the reels are flanked by red velvet curtains. The reels themselves are outlined in lighted bulbs for some glamour.
The symbols aren’t made to look hugely realistic or contemporary, but they’re given a classic feel that’s quite distinctive and feels more authentic for an old-time jazz theme. Jazz is pumped through your speakers on reel spins and wins to build atmosphere, but there’s no ongoing soundtrack.
The aesthetics and sound help to cultivate some of the upbeat vibes and warm intimacy of a smoky, dimly lit club with a bit of glitz as glasses clink and instruments thrum.

In Jazz RTP and Variance
This has a decent 96% RTP. The variance unfortunately isn’t known, and we can’t accurately judge this from our gameplay to be able to say with certainty whether it’s medium volatility or not.

In Jazz Bonus Features
Risk Game
Players have the option of risking their winnings in the chance of doubling them up to 10 times. Choose one of the four face-down cards, and if it beats the Dealer’s card then your prize is doubled and you’ll have the chance to try again. If the Dealer wins any round, your winnings are lost and the game ends. If you don’t want to risk it, at any time you can press ‘Take Win’. The average RTP here is 84%, but chances can be higher/lower depending the Dealer’s card.
Free Games
Three or more Scatters trigger the Free Spins feature. You’ll get 10 free spins with two expanded Jazz Band Joker symbols per spin. The Jokers substitute for all symbols bar the scatter and can multiply the wins by x1, x2 or x3. If there’s no combination to complete, the joker stays concealed. If both jokers on your reels are substituting, then both of their respective multipliers are applied.
In Jazz Review : Overall
The aesthetics and occasional sound make this a more immersive slot, ideal for fans of music and jazz. We also like the creative detailing on the card symbols; often these get ignored in slots, but here they get a musical make-over, like the A with a sad and hat or the K with a keyboard.
The low starting stake should be very appealing for casual players, while the max 250 coin wager should satisfy the higher rollers among us. While the variance isn’t known, the RTP is decent enough, and players could expect some reasonable enough prizes, even if they aren’t earth-shattering.
Gameplay is straightforward but not necessarily user-friendly. It’s rather inconvenient and time-consuming to have to click through all of the payline and wager options without seeing them all displayed. If you make a mistake and go too far, you have to go back through all of the options again.
The free spins bonus has a decent twist with the Joker symbols and multipliers, so this is where bigger wins could be possible. The Risk Game is likewise potentially profitable and ups the ante for those wanting more tense anticipation. However, players wanting a bit more oomph to their slots may find this isn’t quite enough to heighten the longevity of gameplay, but it’s well worth checking out for those multipliers on offer.
