Book of Secrets Extra Dice follows the lineage of "Book of…" slots, transposing the imagery of ancient Egypt into a very readable technical structure. Developed by SYNOT Games, this video slot features a 6-reel, 3-row matrix with 10 fixed paylines. Released on 10/06/2022, it combines iconic symbols – pharaohs, scarabs, and pyramids – with a well-known central mechanic: the Book symbol with dual role (Wild and Scatter), the pivot of the main features.
The core gameplay revolves around triggering Free Spins when 3 or more Book symbols appear, with selection of a Expanding Symbol that can cover an entire reel when part of a winning combination. This "firework-style" approach enhances screen readability: on one side, a 6x3 grid that opens possibilities, on the other an expansion system that densifies each Free Spin sequence. Added to this are a Gamble (Double) option – a color card draw offering potential doubling of a win – and, unique to this version, a 6th reel and an additional Scatter that favor feature triggers.
The combination of elements – unified Wild/Scatter, Expanding Symbol, and 6th reel – gives the "Book of…" model a clear direction: a simple, readable base, enhanced with spectacular moments at the right time. The maximum win reaches 500x the bet, naturally linked with symbol expansion during Free Spins. The game is built in HTML5 and JavaScript, compatible with Android, iOS, and Windows, ensuring identical execution on mobile, tablet, and desktop.
Thematically, book of secrets extra dice plays on fantasized archaeology: temples, relics, and treasures suggested by instantly recognizable icons. This classic imagery supports gameplay that amplifies a small number of key mechanics rather than accumulating additional modules. The result: an experience structured around a tutelary Book, catalyst for Free Spins and trigger of the most distinctive animation in the game, namely the full-reel expansion of the chosen symbol.
The visual setting relies on ancient Egypt imagery: pyramids, artifacts, and pharaonic iconography create an instantly recognizable environment. The choice of a “modernized classic” style aligns with the 6x3 structure: the grid remains sober, while effects linked to Expanding Symbols provide the expected visual impact during key sequences. Nothing superfluous, the focus is on symbol readability, the activation of the Book (Wild/Scatter), and full-column coverage during bonus phases.
The whole reads as an “Extra” variation of the Book of template: the Extra Dice designation signals a version that introduces a 6th reel, complemented by an additional Scatter. This structural extension is felt on screen: a wider grid, better represented bonus triggers, and at the center, the Book orchestrating symbols and features.
The icon hierarchy pairs thematic visuals with base symbols, totaling 9 paying symbols. Key points to note:
The visual balance does not overload the grid: the thematic identity is expressed through a few strong symbols, while the Book draws attention through its dual function and its role as access to Free Spins.
The sound environment fits the ancient universe and accompanies key moments: reel spins, highlighting the Book (Wild/Scatter), then accentuation during Free Spins and the full-reel expansion. Audio cues mainly serve as clear markers for feature transitions and the presence of key symbols.
The structure of Book of Secrets Extra Dice revolves around the Book (Wild/Scatter), Free Spins with an Expanding Symbol, a 6th reel, and a Gamble (Double) option, with a maximum win of 500x the bet.
| Feature | Details |
|---|---|
| Free Spins | Triggered by 3+ Books (Scatter). An Expanding Symbol is selected and can cover an entire reel when part of a winning combination. |
| Expanding Symbol | Symbol chosen before the Free Spins: full-column expansion during a winning configuration, maximizing grid coverage. |
| Wild Symbol | The Book substitutes all standard symbols to complete combinations on the 10 lines. |
| Scatter Symbol | The Book also acts as a Scatter: 3+ trigger the Free Spins. |
| Gamble (Double) | Optional potential doubling via color card draw after a win. |
| 6th Reel | Expanded 6x3 grid compared to previous versions, impacting sequence dynamics. |
| Additional Scatter | Presence of an extra Scatter in this version, favoring bonus access. |
| Maximum Win | Ceiling announced at 500x the bet, especially linked to Free Spins and the Expanding Symbol. |
Triggered by 3 Book symbols (Scatter) or more. Before the series, an Expanding Symbol is selected. When this symbol is part of a combination, it can expand the full height of the reel, increasing the potential winning lines on the 6x3 grid. This expansion highlights the bonus phase, making the column a thematic block.
The Book has dual roles. As Wild, it substitutes other icons to complete configurations on 10 lines. As Scatter, it triggers Free Spins from 3 occurrences, regardless of their positions on the grid. This dual nature emphasizes the symbol’s importance in game sequences.
The Extra Dice version adds a 6th reel and introduces an additional Scatter. This combination broadens trigger occurrences and strengthens the Book’s presence on screen. The 6x3 format retains 10 fixed lines, preserving the “Book of…” structure while allowing a wider grid view.
After a win, a Gamble (Double) option offers a color card draw for potential doubling. The mechanic is intentionally binary and clearly identifiable, consistent with the classic spirit of the model.
The top reference is 500x the bet. The paytable shows a coherent hierarchy: top at x500, then x200, two levels at x75, two at x15, and three at x10 for 5 symbols. This scale aligns with the role of the Expanding Symbol during Free Spins, triggering particularly visible column coverage.
The game runs in HTML5 and JavaScript, available on Android, iOS, and Windows. The interface adapts to mobile, tablet, and desktop screens while maintaining the 6x3 matrix and 10 fixed lines without affecting readability of symbols and the Book (Wild/Scatter).
Book of Secrets Extra Dice focuses the essence of a modern “Book of…” around a few clear markers: a Book with dual function, Free Spins structured by an Expanding Symbol, and a 6th reel that broadens the grid view while preserving the 10 fixed paylines. The setup emphasizes clarity: a recognizable grid, obvious triggers, and a bonus phase visually represented by full-column occupation. The additional Scatter places this “Extra” version in a logic of highlighting the Book as the unique pivot of the features.
Compared to more traditional “Book of…” variants, the key difference lies in the addition of the 6th reel and the strengthening of the Scatter. The framework remains familiar: a paytable with 9 paying symbols, a base of 10 fixed lines, and a maximum reference of 500x the bet aligned with expansions during Free Spins. This approach avoids clutter: few modules, each solidly characterized and immediately readable on the grid.
Within the ecosystem of Ancient Egypt-themed titles, this version stands out for functional sobriety and its visual intensity focused on the Expanding Symbol. The expanded 6x3 structure does not imply excess: it mainly offers a larger area for the Book’s mechanics. This technical coherence aligns with SYNOT Games’ philosophy: sharp rendering, stable HTML5/JS operation, and multiplatform compatibility (Android, iOS, Windows) without compromising readability.
Compared to earlier versions, this “Extra Dice” iteration emphasizes grid width and the Book’s prominence. It does not add a cascade of additional modules but reinforces the pillars of the “Book of…” model: unified Wild/Scatter, Free Spins, and Expanding Symbol. The visual identity remains classic, supported by icons immediately associated with Ancient Egypt, while the gameplay dynamics focus on the bonus phase and the highlighted symbol stretching across the full reel.
In summary, Book of Secrets Extra Dice is defined by a clear footprint: 6 reels, 10 fixed paylines, Book with dual role, Free Spins with Expanding Symbol, Gamble (Double) option, and a 500x bet reference. A readable roadmap that magnifies the Book mechanics rather than diluting them, expressed with the sobriety of an interface designed to remain consistent across mobile, tablet, and desktop.
