How To Play Book of Fusion Slot

It all begins with a base game that is laid down on a 5×3 reel grid, and there are ten fixed paylines in place.

The regular symbol list starts with 10, J, Q, K, and A from a standard deck of cards. These are the lower payers, while the higher values attach to that crazy scientist theme.

On the reels, we have four different gadgets, including a Magnet, and then we have the Scientist himself.

The minimum payout for matching lower-value symbols on adjacent reels is 10x, while the premium icons can pay up to 500x for five on a payline.

The Book symbol plays a dual role in the Book of Fusion slot. If one or two images land, the Book will act as a regular Wild symbol, replacing others and forming a win where possible.

If three Book symbols drop into view anywhere on the reels, they will be classified as Scatters, and they will open the free spins round.

Book of Fusion Slot Features

There are very few special symbols in this Book of Fusion video slot, but the Book is extremely powerful. When three of them drop onto the reels, in any position, they will activate the main Bonus feature.

Bonus and Free Spins

The initial reward is 10 free spins, but there's more to this section. Before this sequence, two icons will be selected at random to become Special symbols. Whenever those symbols form a winning combination, they will expand to cover the entire reel.

Because of this capacity to expand, there can be a payout even when symbols don't appear on matching reels.

Additionally, if another three Scatters fall on a single spin, ten further free spins will be triggered.

Two more special symbols will also be picked. In theory, all base game symbols can be expandable!

Bonus Buy

Players who don't want to wait around for the bonus feature can buy straight in. At the cost of 70x stake, they can activate those initial ten free spins.

Unfortunately, the Bonus Buy won't be available to you if you're a UK player due to UKGC legislation.

Book of Fusion Slot RTP & Volatility

This is one of those online slots where the RTP percentage is variable. The default setting is 95.97%, but it can drop to 89.99 and 93.98 depending on where it’s played. It’s obviously wise to be careful with those deposits and to check on the RTP before committing.

Volatility is high, and slots with this combination tend to follow a similar pattern. Wins may be less frequent, especially in the base game. However, when they do drop, the payouts can be above average. Results will vary from player to player.
