Imagine if there was a fruit-themed online video slot featuring the highly popular ‘Book of…’ mechanics? Well, now there is! 

ThunderSpin casino software is bringing Book of Jam - an online release played on 5 reels, 3 rows, with 10 active paylines, while in terms of available bonus features, punters can expect Wilds, scatters, Free Spins, Expanding Symbols, multipliers, and a Bonus game. 

Worth mentioning is the fact that this is a highly-volatile online game with an RTP of 95.9%. Also, you’ll be able to spin it on all devices including mobile ones. 

Let’s see what this is really all about, shall we? 

Theme and Symbols

At first, Book of Jam seems to be just another fruit-themed online product. However, the developer did its best to harmonize classic gameplay and modern visuals. Behind the reels, you’ll see a beautiful orchard while cherries, lemons, plums, and oranges are at the bottom of the paytable offering up to 50 coins for a combination of 5. 

Grapes, watermelons, gold bells, and red lucky 7s are the premium icons here worth up to 2500 coins for 5 of a kind. Finally, the book symbol acts as a scatter while the golden star icon represents the Wild symbol. 

Betting Options and Other Functions

Book of Jam comes with a standard 5x3 grid with 10 active paylines and in order to form a combo, you’ll need to land at least 3 matching symbols across a single line. 

The minimum available bet sits at 0.1 coins while the maximum one can go as high as 100 coins per spin. 

The title’s high volatility is paired with an RTP of 95.9% which is slightly below the average. The top payout stands at 1000x the bet. 

Special Features

Before we check more complex extras, you should know that Wild symbols will step in for all other icons allowing you to form more winning combinations. Keep in mind that they‘ll appear only on reels 2, 3, and 4. 

3, 4, or 5 scatters anywhere on the reels will activate the Free Spins bonus round and the game will award 10, 15 or 20 spins free of charge respectively. At the start of the feature, one symbol will be randomly selected. 

But, there’s more. During the Free Spins bonus round, punters will be able to trigger Super Bonus Game by landing Bonus Symbols on reels 1, 3, and 5. Fill the bars and earn up to 500x the bet and different multipliers - it’s important to note that the highest available one can go up to x300. 


Book of Jam is definitely a refreshment when it comes to ‘Book of…’ online video slots. ThunderSpin did everything right here and we’re sure that many punters will enjoy Wilds, scatters, Free Spins, Bonus Symbols, a Bonus round, and multipliers.
