Book of Gods (Big Time Gaming) Slot Review

Book of Gods: Slot Overview 

Book of Gods is Big Time Gaming’s interpretation of the “Book” slot genre, blending classical elements made famous by titles like Book of Ra and Book of Dead with its own signature mechanics. Released with a 5×3 reel setup, 243 paylines, and a potent 96.35% RTP, Book of Gods pays homage to the Egyptian slot archetype while incorporating innovative twists like symbol cloning, Feature Drop, and a multi-symbol expansion system during free spins. 

Despite the classic theme, this is not a clone—Book of Gods modernizes the format with expanded mechanics and higher win potential. With a max payout of up to 10,000x, high volatility, and the ability to buy the bonus round, this slot caters to players who enjoy feature-rich gameplay paired with enormous win ceilings.

Design and Graphics 

The visual design in Book of Gods leans heavily into the Ancient Egyptian aesthetic, but with a surreal, almost fantasy-like twist. The background features vivid orange skies, Nile River sailboats, and pyramid silhouettes that feel more painterly than photorealistic—creating an immersive yet stylized vibe. The reels are framed by intricately designed stone columns engraved with hieroglyphics, and the symbols themselves represent both classic slot elements and mythological figures. The low-value symbols are familiar playing card icons (9 through A), while the premium symbols depict four deities: 

Goddess of the Afterlife (Purple) 

God of the Sun (Red) 

God of the Moon (Blue) 

Goddess of the Earth (Green) 

The top symbol, the purple goddess, pays 20x for five-of-a-kind in the base game and serves as the gateway to massive wins during the bonus round. 

Overall, Book of Gods is artistically polished and appealing, successfully modernizing the “book slot” genre while staying rooted in its thematic legacy.

Gameplay Mechanics 

The game runs on a standard 5-reel, 3-row grid with 243 ways to win. Unlike traditional payline games, this system pays as long as matching symbols land on adjacent reels from left to right, regardless of row position. 

Feature Drop 

Book of Gods includes Big Time Gaming’s Feature Drop mechanic, allowing players to purchase entry into the bonus round for 80x the bet. When used, up to 5 scatter symbols may be added to the reels, providing the same bonus experience as a natural trigger—only faster. This is a smart option for players who prefer action-packed sessions without waiting for scatters to align.

Sound and Music 

BTG enhances the slot’s mystical atmosphere with a rich audio landscape. The soundtrack features ethereal chants, soft chimes, and Egyptian-style strings, cultivating a tone of mystery and divine power. It’s subtle during base gameplay, intensifying during bonus rounds and big wins. 

Sound effects punctuate important moments—such as the triggering of free spins or the cloning of symbols—with smooth audio cues. While it doesn’t push boundaries sonically, Book of Gods provides a well-composed and thematically fitting audio experience that supports its visual storytelling.

Bonus Features 

Symbol Cloning 

A standout innovation in Book of Gods is the Cloning Symbol mechanic, which activates on every spin in both the base and bonus game. On each spin, one of the low symbols (9–A) is randomly selected to become the Cloning Symbol. After a win is paid out, any instances of this symbol will expand to fill all positions on their reels, potentially transforming the grid for bigger payouts. 

In the main game, this only applies to lower-value symbols. But during free spins, the cloned symbol can be one of the premium God symbols, opening the door to significant rewards. 

Free Spins Feature 

The free spins round is triggered by landing 3, 4, or 5 Wild/Scatter symbols, awarding 15, 20, or 25 free spins, respectively. When the bonus begins: 

The Book of Gods opens to reveal one God symbol, which becomes the Cloning Symbol for the duration of the round. 

Every time a win includes the chosen symbol, it expands across its reel before payouts are calculated. 

Landing 3 or more scatters during the bonus retriggers the feature, adding +15, +20, or +25 free spins and revealing an additional God symbol to act as a Cloning Symbol. 

This can happen up to three times, meaning players can eventually have all four premium God symbols active at once, with the possibility to retrigger further free spins indefinitely after that. 

This mechanic mirrors the expanding symbol feature from other “Book” slots but amplifies it by layering multiple expanding premiums—offering one of the most lucrative retrigger systems in the genre.

Betting Options and Payouts 

Book of Gods offers a flexible betting range, with wagers from €0.10 to €40 per spin, catering to casual players and high rollers alike. 

Key Stats: 

Reels: 5 

Rows: 3 

Paylines: 243 ways 

RTP: 96.35% 

Volatility: High 

Max Win: 10,000x (4860x from one bonus payout reported) 

Min/Max Bet: €0.10 / €40 

Bonus Buy Cost: 80x the bet 

While base game payouts are decent, it’s clear that the real money is in the bonus round. Landing a full screen of the Goddess of the Afterlife during free spins yields 4860x the stake, while multiple expanding God symbols in a well-retriggered bonus can push rewards even higher.

Conclusion 

Book of Gods is a brilliant reinvention of the Book slot genre, combining time-tested features with modern twists. The use of symbol cloning, 243 ways to win, and multi-symbol expansion during free spins sets it apart from more traditional counterparts, and Big Time Gaming’s incorporation of the Feature Drop system provides an optional fast-track for bonus hunters. 

The visual design is elegant and thematic, the gameplay is layered but accessible, and the potential for unlimited retriggers makes for some seriously long and rewarding sessions. With a top win of up to 10,000x the stake, Book of Gods offers high-risk, high-reward action that’s particularly satisfying for players chasing those legendary full screens of premium symbols. 

While it doesn’t entirely abandon its roots, Book of Gods improves upon the formula in clever ways. For fans of Book of Ra, Book of Dead, and other expansion-style slots, this is a must-play title that offers both massive win potential and a fresh twist on a beloved genre.
