Book of Whispers – Slot Overview
Trusty Gaming, a partner studio of Hacksaw Gaming, dusts off one of the most iconic slot mechanics with Book of Whispers — a classic “Book of” style slot that keeps things strictly traditional. If you’re expecting a fresh spin or innovative take on the genre, you won’t find it here. Instead, Book of Whispers sticks faithfully to the tried-and-tested formula: book scatters, free spins, and special expanding symbols that pay from anywhere.
Visually, Book of Whispers trades desert sands for something more vibrant — a mystical jungle teeming with glowing flora and magical artifacts. The lush green surroundings give the game a slightly spiritual, almost Avatar-esque feel, as if the characters on the reels are in tune with a deeper, nature-connected world. It’s an atmospheric change from the usual tomb-raiding aesthetic, even if the gameplay itself remains firmly rooted in the past.
Book of Whispers – Base Game & Betting Details
Set within a frame of wood and shimmering gems, Book of Whispers unfolds across a classic 5×3 reel grid with 9 paylines, paying left to right. Standard symbol wins must land on adjacent reels, but during free spins, the special expanding symbols can pay from anywhere, staying true to the classic “Book of” format.
The game runs on a medium to high volatility model, with stakes ranging from €0.10 to €100 per spin. Players can expect a 96.24% RTP on the higher-return version, while some markets may encounter a lower 94.49% RTP variant. There’s no ante bet or multiple feature modes here — Book of Whispers keeps things minimal with a single bonus buy option.
Symbol-wise, the low-paying icons are five ancient patterns etched in stone, while the high-paying symbols consist of four unique character portraits. Full-line wins of low pays award 5x to 10x the bet, while the character symbols can dish out 75x up to 500x for five of a kind.
Book of Whispers – Bonus Features & Free Spins
At the heart of the action lies a large, ornate book adorned with a glowing gem, which acts as both the wild and scatter symbol. As a wild, it substitutes for all regular symbols (but not special expanding ones). Land 3, 4, or 5 books on the reels to trigger 5x, 10x, or 25x your bet, respectively — and unlock 10 free spins.
Free Spins & Expanding Symbol
Before free spins begin, one symbol is randomly selected to act as the special expanding symbol. When this symbol is part of a winning combo, it will expand to cover its entire reel. Crucially, these symbols pay from any position, regardless of adjacency, and wins are calculated across all 9 paylines. Land 3 additional book scatters during free spins, and +10 more spins are awarded.
Feature Buy Option
For those who want to skip the base game grind, the bonus round can be purchased for 100x your bet. This guarantees entry to the free spins feature, with one randomly chosen expanding symbol.
Book of Whispers – Slot Verdict
Trusty Gaming still hasn’t delivered a breakout hit, and unfortunately, Book of Whispers doesn’t change that. While Monkey Frenzy showed glimmers of creativity, Book of Whispers pulls things back into the realm of the forgettable. It’s especially disappointing given Trusty Gaming’s association with Hacksaw Gaming — a studio known for pushing the boundaries of slot innovation. While partnerships with developers like Backseat Gaming and Bullshark Games have yielded exciting results, that creative spark hasn’t yet rubbed off here.
Book of Whispers is a textbook example of playing it safe. The Book of Ra-style mechanic has been replicated endlessly across the industry, often with inventive twists to help it stand out. But this one? It sticks rigidly to the basics — no fresh angle, no unique hook, no ambition. Among a sea of similar “Book of” games, this one feels like it’s hiding in the middle of the pack, reluctant to take a risk. And in a genre this saturated, timidness just won’t cut it.
That said, it’s not all bad. The game looks decent, the jungle aesthetic is vibrant, and the special expanding symbols work as expected. Plus, the 5,000x max win is in line with genre standards. But for a game set in such a lush environment, Book of Whispers feels surprisingly flat — a visually inviting slot that plays it far too safe when it matters most.
