Book Of Fusion Review

Book slots have been extremely popular even since the legendary Book of Ra hit the market, and game studios don't seem to stop producing more and more slots based on the expanding free spins. Book of Fusion is yet another addition to the book niche by developer Light and Wonder, and aside from a lovely reskin, it doesn't bring anything really new to the genre.

As the title implies, the Book of Fusion slot sports an alchemy theme, and the actions take place in a crazy scientist's lab. Behind the semi-transparent 5x3 reel set with 10 winlines, different machines, devices, and alchemy ingredients make up the backdrop. Overall, the game looks fine, and the thrilling soundtrack immerses you in the atmosphere.

The slot comes with a betting range of €0.1 to €35 per spin, which should appeal to many. The volatility is high, while the default RTP is 95.97%, which is a whisker beneath the average. Keep in mind that the game has RTP ranges, meaning that the payback value can be different between the casinos. The other possible return rate values are 89.99% and 93.98%, so be sure to check the paytable to find a better RTP. The maximum win is capped at €250,000, which is slightly over 7,000x the stake.

The symbol collection includes 10 regular symbols that are split in half into two categories. On the lower side, we see classic A-10 card royals, while the premiums are made up of four different gadgets and a mad scientist. All low symbols pay from 3-of-a-kind and more, and the high pays need only two. Five-of-a-kind low symbol wins are worth from 10x to 15x your bet, and premiums pay from 75x to 500x the bet. Book symbols are both Wilds and Scatters, and not only it substitutes for any other regular symbol to help you achieve wins, but also pays up to 500x for line wins. Book symbols also play into the features, though, in that case the prize will be 2x, 20x, or 200x the stake for 3, 4, or 5 symbols respectively.

Book of Fusion Slot Features

The Book of Fusion slot relies heavily on the Free Spins feature, which is where most wins come from. Landing 3 or more Scatters anywhere on the reels during the base game activates the bonus, and players receive 10 free spins to start with.

In the beginning, two random symbols are chosen to become special expanding symbols for the remainder of the feature. These symbols do not necessarily need to land adjacently on the reels to award a win, and they expand to cover the reels entirely whenever a winning combination is possible. Moreover, retriggers are possible, plus extra two special symbols are awarded. However, if all 10 symbols turn into special, the bonus cannot be retriggered.

Review Summary

It's really hard to surprise players with a Book of Ra-inspired release, as we've seen pretty much everything in the niche. However, Book of Fusion is still a decent option. It offers two symbols instead of one in the free games feature, and that can boost the possible rewards significantly. More importantly, you turn additional symbols into the expanding ones upon a retrigger, and it's possible to convert the entire paytable and receive guaranteed big wins on each spin. All in all, Book of Fusion is good, and those into the science theme will appreciate Light and Wonder's effort.
