Book of Fusion comes from Light & Wonder, a January 2022 release that blends steampunk styling with sci-fi and fantasy adventure. Under the hood it runs a high-volatility math model with an RTP of 96.00%, and the feature list includes wilds, scatters, free spins, expanding symbols, a bonus game, and a buy bonus option.
Book of Fusion uses line-based wins, so payouts land along paylines. The wild symbol substitutes for regular symbols to help complete winning combinations, while the scatter operates outside the line system and counts wherever it lands on the reels.
The headline extras in Book of Fusion are its free spins round and a bonus game, a separate side round that breaks up standard base play. Expanding symbols can grow to cover entire reels. For players who prefer not to wait for a natural trigger, the buy bonus option offers direct, paid entry into a bonus round.
At 96.00%, the RTP in Book of Fusion sits exactly on the 96% industry average, so long-term returns are neither generous nor stingy by market standards. The volatility is high, and that shapes the entire session profile: wins arrive less frequently, dry spells can stretch, and the larger payouts concentrate in fewer hits. That setup needs patience and bankroll headroom. No official max win figure is listed for this game.
The theme mix reads steampunk first, with sci-fi, fantasy, and adventure in support. Expect a retro-mechanical atmosphere pushed toward the futuristic, with the fantasy and adventure elements giving the package a quest-like tone rather than a strict period piece.
Book of Fusion keeps things straightforward: a broad feature set, an average RTP, and a high-volatility engine aimed at players who prefer rarer, larger hits over a steady drip of small wins. The steampunk and sci-fi blend gives it personality. If the theme appeals and you have the patience high volatility demands, the free demo on this page is the sensible place to start.
