Book Of Fusion - Review, Demo Play, Payout, Free Spins & Bonuses

It has a 5x3 grid and 10 fixed paylines. According to the makers, the game’s RTP is 89.99 per cent and the variance level is high. It is set in an ancient laboratory full of machines, dials and chemicals. It includes free spins and wilds.

Introduction

This Light and Wonder slot combines the payline mechanics of a traditional slot machine with the thematic freedom of modern online slots. During the course of our Book of Fusion slot review we hope to find all the positives and flag up any shortcomings. Light and Wonder was founded in the world capital of gambling, Las Vegas, in 2018. Through a series of acquisitions the company has become one of the world largest software providers for online slots and other casino games.

Book of Fusion is an online slot machine that sticks to the traditions with its 10 fixed paylines - very different from games like the Irish Riches Megaways slot with its vast number of winning permutations. It has five reels and three rows. The minimum bet size is 0.10 and the maximum is 35. There are 11 regular symbols: the Book, the Scientist, the Generator, the Switch, the Meter, the Magnet and the five highest playing cards.

Theme, Graphics and Soundtrack

A lot of thought has gone into the graphics. The backdrop of the laboratory is immensely detailed, and the images on the semi-opaque grid are equally impressive. The soundtrack consists of a bass-heavy, slightly spooky electronic loop with some lab sound effects to add to the atmosphere.

Book of Fusion RTP and Variance

According to Light and Wonder, the RTP of Book of Fusion is 89.99 per cent, which is below average. However, at certain levels of play a different RTP applies, so you may experience 93.98 per cent and 95.87 per cent. Its volatility is high. 

How to Play Book of Fusion

1. Winning combinations must occur on adjacent reels, beginning from the furthest left. For the lower-value symbols you need at least three to match, but with the higher-value symbols you can win with just two.
2. In order to choose your bet level, click on the three-dots. This gives you a slider which you move left for a lower bet and right for a higher one. Alternatively, you may select the options shown in the boxes. 
3. Wins on different paylines and coinciding wins are added together.
4. Open the bet settings by clicking on the coins icon. Use the plus and minus buttons to adjust the amount.
5. Click on the large circular arrow to set the reels spinning.
6. Click the lightning bolt button to shift into fast play mode.
7. Click the smaller spin button to enter autoplay settings mode. Here you can choose a number of auto spins from 5 to 100. You can also set the mode to quit if you reach a specified single win limit or loss limit.
8. We encourage you to play online slots in a responsible manner. We are supporters of safe gaming initiatives and would stress the importance of never betting more than you can afford to lose. Playing an online slot machine in its no deposit slot form is a safe way of learning how a game works before risking money. If you choose to bet, then make sure you stop playing when you are no longer enjoying it and always make use of the self-exclusion features in your gaming account.

Book of Fusion Bonus Features

Wilds

The Wild substitutes for all symbols in the base game. The Wild also substitutes for any symbol in payline wins, and it has a scatter payout. The Wild does not substitute for Growing symbols during the bonus round.

Free Spins Bonus

When three or more Wild symbols appear scattered in view, the Free Spins Bonus is activated. 10 free spins are then awarded. At the start of the free spins round two special symbols are chosen at random and grow to fill the reels. If you retrigger the bonus round, you will be awarded two more special symbols.

Growing symbols need not appear adjacent to each other in order to form a winning combination. If all 10 symbols are active during the free spins round, the bonus cannot be retriggered. The Wild does not substitute as any of the special symbols in the bonus round.

Book of Fusion Review: Our Verdict

This delivers less than its impressive look promises. With such a rich theme we hoped for more complexity in its bonus features. The growing symbols are a refreshing idea in the free spins round, but there isn’t a genuine bonus game. Meanwhile, the RTP is quite poor. However, it’s fun in shortish doses.
