Book of Truth

Book of Truth by TrueLab takes the popular “Book of Truth” formula and turns it into something far more ambitious. While at its core, it features expanding symbols and free spins, this slot distinguishes itself with two different free spins modes – the standard expanding symbol bonus and the True Free Spins, where all symbols become expanding ones.

With a maximum win potential of 15,000x your stake, this is one of the more volatile entries in the genre, appealing to players who seek high-risk, high-reward gameplay.

Book of Truth leans into dark, mystical adventure with a richly detailed ancient temple aesthetic.

• Visuals: The reels are adorned with hieroglyphic-style patterns, glowing gems, and shadowy ruins.
• Atmosphere: A mysterious and ominous tone pervades, setting it apart from brighter “Book of Ra” clones.
• Symbols: Golden relics, mythical artifacts, and adventurers appear alongside classic low-value symbols.
• Soundtrack: Deep, cinematic score with eerie undertones enhances the feeling of uncovering forbidden secrets.

This slot leans more toward the horror-fantasy genre than traditional Egyptian designs, making it stand out.

1. Adjust paylines (1–10) and set your stake.
2. Spin the reels – wins pay left to right across active paylines.
3. Look for the Book symbol – acting as both wild and scatter.
4. Land 3+ books to trigger free spins, or hit 5 scatters for True Free Spins.
5. Expanding symbols are the key to unlocking the slot’s max potential.

Standard Free Spins

• Trigger: 3 or 4 book scatters → 10 free spins + payout of 2x or 20x stake.
• A random regular symbol is chosen to expand.
• Expanding symbols pay on all active lines, even if not adjacent.

True Free Spins

• Trigger: 5 book scatters → 10 True Free Spins + 200x payout.
• In this round, all regular symbols are expanding.
• This makes it possible to hit full-screen wins of any symbol.

Bonus Buy Options (where permitted)

• 10 Standard Free Spins: 89x the stake.
• 10 True Free Spins: 536x the stake.
• Costs vary if fewer than 10 paylines are active.

• Chase the books: Triggering True Free Spins with 5 scatters is the ultimate route to massive wins.
• Full-screen expansions: Expanded premium symbols can generate payouts worth thousands of times the stake.
• Line adjustment strategy: Playing with fewer paylines lowers buy-in costs but increases volatility.
• High volatility management: Be prepared for long dry spells – but the rewards can be game-changing.

• Book of Dead (Play’n GO) – The classic “Book of” slot.
• Book of Shadows (Nolimit City) – Dark horror take with reel height adjustment.
• Tome of Madness (Play’n GO) – Lovecraft-inspired cascading slot.
• Book of Ra Deluxe (Novomatic) – The original that started it all.

Book of Truth is a premium high-volatility slot that appeals to hardcore “Book” fans and adventurous players. With its True Free Spins mode, it brings a level of intensity rarely seen in this genre, making full-screen wins of almost any symbol possible.

• Strengths: Two free spins modes, very high win potential (15,000x), buy bonus options, unique dark theme.
• Drawbacks: Extremely volatile, bonus buy costs are steep, not ideal for casual players.

Best suited for: Fans of Book of Dead who want a darker, riskier, and more explosive version.
