Picture a Victorian inventor’s workshop, except the inventor figured out how to weaponize free spins. That’s Book of Fusion, a 2022 Light & Wonder release running on the old NOVA Core v4.0.2 pipeline inherited from NextGen. The 5×3 grid sits behind riveted bronze pipework, with teal-tinted reels glowing between copper rails and bubbling alchemy flasks on the right edge. Chrome pink-and-blue lettering finishes the look. It’s steampunk, sure, but the kind that actually commits to the bit.
Mechanically you get 10 fixed paylines, 96% RTP, and high volatility. Bets run from $0.01 to $35, defaulting to $2. The Mad Scientist works as the Wild and substitutes across line wins, but he also pays from anywhere on the reels as a scatter, which is a nice double-duty trick. Standard symbols cover the Tesla-coil bulb, an orange-red electromagnet, a voltage meter, and a valve regulator. Ten paylines feels tight by modern standards, honestly. You’ll notice the dead spins.
The bonus is where Fusion earns its name. Land three or more purple-and-gold book scatters anywhere and you get 10 free spins, but here’s the twist: at the start of the round the game randomly picks two Special Symbols instead of the classic single one. Both expand to fill entire reels and pay anywhere across all five columns, no adjacency required. Retrigger by landing three more books and you get +10 spins plus two additional Specials added to the active pool. Keep retriggering and eventually every base symbol can expand. Is that as wild as it sounds? Pretty much, yes.
There’s a Buy Pass shortcut too, which guarantees a spin landing at least three bonus books. Cost and Buy Pass RTP both show on the confirmation screen, which I appreciate. Availability depends on jurisdiction though, and UK retail venues often disable it entirely.
One real gripe: Light & Wonder never published a max-win multiplier. The ceiling exists somewhere, obviously, but you’re flying blind on how big this thing can actually pay. For a math model built around stacking expanding symbols, that’s an odd thing to keep quiet about.
