Book Of Fusion

Book of Fusion by SG Digital is a fresh take on the classic Book of Fusion slot formula. While it retains the familiar mix of wild/scatter hybrid books and expanding special symbols, it introduces a twist – instead of one expanding symbol, players get two from the start, one high-paying and one low-paying. With potential retriggers adding even more expanding symbols, it’s possible to transform the entire reel set into a grid of full-screen payers.

Packed with 10 paylines, a 5x3 grid, and a maximum payout of 7,142x the bet, Book of Fusion blends familiar mechanics with a powerful new feature twist.

The design of Book of Fusion leans heavily on classic Egyptian inspiration, fused with a modern, scientific twist – hence the name.

• Visuals: A glowing book opens in bursts of energy to select special symbols, while reels are set against an alchemy-style laboratory backdrop filled with golden ornaments and fusion effects.
• Symbols: Hieroglyphics, royal card icons, and Egyptian deities appear alongside the almighty Book.
• Soundtrack: A dramatic, cinematic score with mystical tones, shifting into suspenseful beats during free spins.
• Effects: Expanding symbols burst with energy as they lock across reels, amplifying the slot’s intensity.

The result is a classic-meets-modern experience that keeps players visually and thematically engaged.

1. Set your bet size – typically from €0.10 to €100 per spin.
2. Spin the reels – wins are awarded across 10 fixed paylines.
3. Watch for the Book symbol – it acts as both wild and scatter.
4. Land 3+ Books to trigger free spins, where expanding symbols take center stage.
5. Manage bankroll carefully, as this is a high-volatility slot with potentially long dry spells.

Book Wild/Scatter

• Substitutes for all symbols to complete line wins.
• Landing 3, 4, or 5 books awards 2x, 20x, or 200x the bet + 10 free spins.

Free Spins with Dual Expanding Symbols

• Before free spins begin, the book selects two special expanding symbols (one low, one high).
• Whenever these symbols form a win, they expand to cover their reels.
• Expanded symbols pay from any position, not just left-to-right.

Retriggers with Additional Expanding Symbols

• Land 3+ scatters during free spins to retrigger +10 spins.
• Each retrigger adds two more symbols as expanders.
• Up to all 10 symbols can become expanders. At this point, retriggers stop.

Bonus Buy (where available)

• Free Spins can be purchased for 70x the bet, skipping straight to the feature.

• Focus on Book scatters to unlock free spins, where big wins are possible.

• Expanding symbols pay regardless of adjacency, making full-screen payouts achievable.

• Retriggers with more expanding symbols greatly increase potential.

• High volatility means patience and bankroll management are key.

• Book of Dead (Play’n GO) – The original cult favorite book slot.
• Legacy of Egypt (Play’n GO) – Egyptian theme with multiplier wheels.
• Book of Sheba (iSoftBet) – Book mechanics with golden expanding reels.
• Book of Truth (TrueLab) – Two free spins modes with different expansion systems.

Book of Fusion is a clever evolution of the classic “Book of” genre. By doubling the expanding symbols and allowing more to unlock through retriggers, SG Digital provides fresh gameplay and higher excitement levels compared to traditional versions.

• Strengths: Dual expanders, retrigger depth, solid 7,142x max win, bonus buy option.
• Drawbacks: RTP slightly below 96%, high volatility with long dry spells, traditional theme may feel familiar.
