About In Jazz

Gameplay and Mechanics

The Basics

Endorphina’s In Jazz is a 5-reel, 3-row slot game with 25 adjustable paylines. Released on April 28, 2017, it offers a nostalgic journey back to the era of live jazz bands in small clubs. The game allows bets ranging from €0.01 to €250, catering to a wide range of players​​.

Special Features

The game is enriched with special symbols: Wilds and Scatters. The Wild symbol, offering multipliers of 100x, 500x, and 1,000x, substitutes other symbols to complete winning combinations, while the Scatter symbol triggers the Free Spins feature and can multiply the stake by up to 200x​​.

Theme and Design

Visual and Audio Elements

In Jazz excels in creating an authentic jazz club atmosphere. The background features a lavish club with a balcony, surrounded by crimson velvet curtains and filled with hazy orange light. The reels themselves are outlined in illuminated lights, complementing the dim, smoky setting. Symbol designs include both low-value (10 to A) and high-value symbols, represented by musical instruments and jazz band artists​​.

RTP and Volatility

The game has an RTP (Return to Player) of 96.06% and exhibits medium-high volatility. This balance indicates that while players face moderate to high risks, the rewards can be equally substantial. The RTP reflects the theoretical percentage of bets that players can expect to win back over time​​.

Mobile Compatibility

In Jazz is built using HTML5 technology, ensuring seamless play across various devices including Android, Windows, and iOS. This cross-platform compatibility allows players to enjoy the game on smartphones, tablets, and computers​​.

Free Spins and Bonus Features

Free Spins

Landing three or more Scatter symbols triggers the Free Spins bonus game, where players are awarded 10 free spins. During these spins, players benefit from two jokers per spin, which act as wilds and cover entire reels. These jokers – the Saxophonist, Double Bass player, and Singer – offer multipliers of 1x, 2x, and 3x respectively​​.

Risk Game

The Risk Game feature allows players to potentially double their winnings up to 10 times. This feature is activated after a winning spin, challenging players to pick a higher card than the dealer’s. The inclusion of the Joker card, which beats all others, adds an extra layer of excitement to this feature​​.

Maximum Win Potential

In Jazz offers a maximum win of 2,500x the bet. Although the game does not feature a jackpot, players can significantly boost their winnings through a combination of symbol matches, Free Spins, and the Risk Game feature​​.


Endorphina’s In Jazz is a masterfully designed slot game that not only pays tribute to the golden era of jazz but also offers a rich gaming experience with its array of features, decent payouts, and immersive theme. Its combination of high-quality graphics, engaging gameplay, and mobile compatibility makes it an attractive choice for both jazz enthusiasts and slot players alike​​​​.
