Book of Jam Review
In mid-2019, a developer released their very first Book of ... mechanic slot called Book of Treasures. It has a higher RTP and max win than Book of Jam, but this game stands out with its warm and comforting feel. The fruit garden backdrop is animated, and the trees sway gently as you play.
The game features big and juicy fruit symbols within the wood-framed 5x3 reel set, and the bonus round revolves around a chosen expanding symbol. This game includes the possibility of triggering a Super Bonus Pick’em Game from within the regular bonus round, which can award an extra 500x, but the max win is capped at 1,000x your stake.
Book of Jam Slot Features
In an unusual twist for this genre, the Book Scatter does not act as a wild. Instead, there is a yellow star Wild that can land on the 3 middle reels only, substituting for all regular pay symbols. The wild has no value and can appear in the base game and the bonus round.
The Jam Recipe Book scatter can land anywhere, and it pays 2, 20 or 200 x your stake for 3, 4 or 5 in view. This also triggers the ‘Book of’ mechanic Bonus Round, and you get 10, 15 or 20 free spins. A regular pay symbol is randomly chosen up front, and this becomes the special expanding symbol.
The expanding symbol feature triggers whenever you land the special symbol on 3 to 5 different reels. The special symbols will expand to cover the entire reels after payouts are summed up, and they pay regardless of whether the reels are adjacent. A special Bonus Symbol can land during the feature.
The purple fruit-splatter Bonus Symbol can appear on reels 1, 3 and 5 only, adding +1 free spin and +1 to the Super Bonus meter on the left. The jam jar fills if you land at least 5 Bonus Symbols, triggering the Pick Em Bonus Game after the free spins round ends.
You will pick from 5 jars at the bottom of a 5x5 rack, providing bet multiplier prizes:
- Pickles jar - guarantees a win between 10x and 15x your stake.
- Strawberry jar - awards a prize of 15x, 20x, 25x, 30x or 35x your stake.
- Blueberry jar - you win either 40x, 45x, 50x, or nothing.
- Plum jar - awards 75x, 100x or nothing.
- Lemon jar - pays 300x your stake or nothing.
The feature ends if you pick a jar worth nothing, only possible on the 3rd shelf. You can win up to 500x your stake in total.
The 200 Spins Book of Jam Slot Experience
Some smaller payouts occur in the base game, before the bonus round is triggered. The lowest-value cherry symbol was the chosen expanding symbol, providing plenty of wins. The Super Bonus Pick’em Game was also triggered.
Review Summary
Book of Jam is a cozy ‘Book slot’. It's a low-tempo game with clear visuals that may appeal to older players. It is akin to the slot version of slow television.
Younger players might appreciate the nostalgic value, but the 1,000x max win may not compete in this genre. The Book-style bonus round plays out as usual, with the added benefit of a possible Pick’em Game trigger, which provides extra wins.
| Pros | Cons |
|---|---|
| Wild separate from book scatter | The 1,000x potential is low for this genre |
| FS w/ chosen expanding symbol | |
| FS symbol collect Pick’em Bonus trigger | |
| Win up to 500x extra from the Pick Bonus |
If you enjoy Book of Jam Slot you should also try:
Book of Treasures - is a Mayan-themed Book slot installment, and it comes with transparent reels. A pay symbol is chosen at the bottom of the middle reel per spin, and it can trigger expanding symbol wins in the base game. The FS round comes with up to 3 expanding symbols, and you can win up to 1,500x your stake.
Mount Magmas - is one to try if you enjoy the Pick’em Bonus in the game at hand. Magma symbols leave wilds behind as they are collected, and this can trigger the Volcano Pick’em Game. The feature comes with 11 rows, and you can work your way up to a 20,000x your stake payout.
