Book of Truth Online Slot Review

3.0 /5

Book of Truth marks TrueLab’s ambitious entry into the crowded “Book of” genre, where countless slots have already staked their claim on Ancient Egyptian territory. Rather than simply copying the formula, TrueLab studied what makes these games tick and asked a bold question: what if all symbols could expand simultaneously? The result is a 5-reel, 3-row video slot with adjustable paylines (1-10) that respects tradition while pushing meaningful boundaries.

The standard free spins feature behaves exactly as fans expect—scatter triggers, expanding symbol selection, and the familiar rhythm of anticipation. But lurking beneath this comfortable surface is the True Free Spins feature, triggered by landing five Book scatters, where every single symbol becomes an expanding symbol from the very first spin.

The sections below will highlight how these aspects shape both the pacing and feel of the gameplay.

Graphics, Sounds and Animations

3.0 /5

TrueLab’s art direction transforms the overused Egyptian theme into something genuinely atmospheric. The temple setting emerges from darkness, lit by burning braziers that cast flickering orange light across weathered stone. Towering pharaoh statues flank the reels; their shadowed features suggesting ancient mysteries waiting to be uncovered.

The symbol design demonstrates similar craftsmanship. Egyptian gods take center stage as premium symbols, with Anubis in gleaming gold, Bastet in rich emerald, and Horus shining in cobalt and gold tones. Each deity symbol occupies its frame with personality rather than serving as generic artwork. Card symbols (10-A) receive appropriate Egyptian treatment with hieroglyphic-inspired styling and warm amber coloring that integrates them into the theme rather than leaving them as obvious filler.

For players who enjoy this expanding symbol mechanic, exploring other popular Truelab games with free spins reveals similar attention to feature design across the developer’s portfolio.

The soundtrack deserves particular recognition. Heavy Arabic musical influences dominate, with dramatic string sections and powerful vocal performances that wouldn’t feel out of place in a film score. The composition builds tension during base play, then swells to epic proportions during bonus rounds.

Where Book of Truth truly excels is animation quality. Standard wins trigger satisfying glow effects with symbols pulsing as paylines illuminate. The expanding symbol animation during free spins delivers visceral satisfaction as chosen icons stretch dramatically to fill their reels, accompanied by golden light that emphasizes their transformation from standard to special. When multiple expanding symbols land simultaneously in True Free Spins, the screen becomes a festival of stretching icons and connecting paylines that creates genuine visual excitement.

RTP, Payout and Volatility

3.5 /5

Book of Truth launches with a 96.33% RTP in its optimal configuration, positioning it favorably above the 96% industry standard and ahead of most “Book of” competitors. This figure promises better theoretical returns during extended play, though players must verify which of three available settings (96.33%, 94%, 92.14%) their chosen casino implements. Medium volatility creates a playing experience that balances regular engagement with meaningful win potential.

The paytable follows logical value hierarchy. The adventurer tops premium symbols at 500x the stake for five-of-a-kind, matching the Book symbol’s payout when it appears as a regular icon. Horus delivers 200x for maximum combinations, while Bastet and Anubis both pay 75x for full lines.

Card symbols range from 10x to 40x for five-of-a-kind, providing frequent small wins that sustain gameplay momentum between premium hits. Since RTP configurations vary between operators, checking reviews of best real money casinos for slots helps identify which platforms offer the ideal setting for this title.

The betting range from €0.01 to €100 accommodates virtually every bankroll type. Penny slots enthusiasts can explore mechanics with minimal exposure, while high-stakes players have room for meaningful action. The adjustable 1-10 payline system lets players reduce lines in base play to extend sessions and activate all lines during bonus features for maximum wins.

The 15,000x maximum win represents Book of Truth’s most compelling mathematical feature. This ceiling triples the standard 5,000x found in most “Book of” slots, creating genuinely exciting potential rather than incremental improvement.

Features

3.5 /5

TrueLab concentrated development resources on perfecting two interconnected bonus tiers rather than cluttering gameplay with superficial additions. This design delivers features that are engaging and rewarding, with True Free Spins bringing a rare and innovative touch to an often-predictable genre.

Book Symbol – Wild and Scatter

The Book serves dual mechanical purposes while maintaining elegant simplicity. As a wild, it substitutes for all regular pay symbols to complete or enhance winning combinations, appearing on any reel during base gameplay. Its substitution power proves particularly valuable when premium symbols land partially, turning near-misses into paying wins.

As a scatter, the Book triggers both bonus tiers based on quantity landed. This dual functionality creates constant relevance. Every Book appearance matters whether it’s helping complete a base game combination or accumulating toward feature activation.

As TrueLab releases gain wider distribution, Book of Truth is becoming available at newest online casino sites that regularly add fresh titles to their game libraries.

Standard Free Spins (3-4 Scatters)

Landing three Book scatters grants 10 free spins along with an immediate 2x stake scatter win, while four scatters increase the scatter payout to 20x, maintaining the 10-spin allocation. Before the spins begin, one regular symbol is randomly selected to act as the expanding symbol for the feature.

During free spins, whenever the chosen symbol appears on the reels, it expands vertically to fill its entire reel. Expanded symbols pay on all active paylines, regardless of adjacency, and landing three or more can generate multi-line payouts, especially when premium symbols are selected.

The feature also allows re-triggers. Hitting three or more scatters during free spins awards an additional 10 spins while keeping the same expanding symbol. This gives players extended opportunities to land significant wins as spins accumulate.

True Free Spins (5 Scatters)

Landing five Book scatters activates Book of Truth’s signature True Free Spins—granting 10 spins and an immediate 200x stake scatter win. Unlike the standard free spins, all regular symbols automatically become expanding symbols for the entire feature, eliminating the need for symbol selection.

During True Free Spins, every symbol that lands expands to fill its reel before payouts are calculated. With every icon possessing expansion properties, nearly every spin produces multiple expanding symbol combinations across active paylines. The reels are alive with stretching symbols and continuous wins, delivering an experience unmatched by typical “Book of” variants.

For those looking to try this feature with bonus funds, comparing best new casino bonuses can help find welcome offers that include free spins, or deposit matches suitable for exploring high-variance bonus rounds.

Buy Bonus Options

Players can access instant entry into bonus features via the buy option. Standard Free Spins are available for 89x your stake, while True Free Spins cost 536x your stake, assuming all 10 paylines are active. Reducing the number of active paylines proportionally lowers these costs, offering flexibility for different bankroll sizes.
