Book of Fusion Review

Everyone has wondered what happens in a mad scientist's lab and Light & Wonder is giving players the perfect opportunity to do this in Book of Fusion.

Watch the sparks fly in Book of Fusion that plays on 5-reels with 10 paylines. This slot is all about the free spins round that can even lead to wins of up to 7,142x the stake.


Book of Fusion opens up with a static image that features a whole bunch of gadgets from a scientist as well as test tubes full of different coloured liquids.

On the reels, there are typical symbols of 10 to A as well as different gizmos and the mad scientist acting as higher paying symbols. The music for this slot feels like it's from the 1980s with a variety of different instruments and sounds creating something bizarre but fitting.


There is absolutely nothing complicated in this slot as the only real feature is the free spins round. Book of Fusion is ridiculously easy to pick up and play with no difficult rules to learn.

The right side of the reels has the spin and bet level button but the other menus are to the left of the reels. Non-UK players will find the bonus buy button at the bottom left of the screen.

Win Potential

Book of Fusion has a mediocre win potential with starts off strong with a decent maximum win of 7,142x the stake which can be achieved through the free spins round.

As for the RTP, this high volatility slot has an under the average standard of 95.97% which is a little disappointing. It's close to the RTP average of 96% but still under.

Our Verdict

Players looking for complicated slots should avoid Book of Fusion as the gameplay is ridiculously simple and intended for newcomers or casual players looking for easy gameplay.

Whilst the design is a little outdated, it's not too distracting and matches the simplicity of the game. Book of Fusion is the perfect slot to pick up if you are new to online slots or are looking for something unchallenging.
