Master the ancient powers buried in the old books of magicians, wizards, and sorcerers to unlock massive wins at the latest Book of Fire Slot from Merkur Gaming!

Alchemists began with the mission to discover the philosopher’s stone. In other words, the source of immortality. Not sure about immortality but OJO can definitely recommend a great source of huge cash wins! Because that is what the alchemy-themed Book of Fire slot from Merkur Gaming delivers!

Book of Fire Slot

OJO just loves the idea of uncovering ancient mysteries and unlocking secret powers! So, when the Book of Fire slot was released by Merkur Gaming in late 2021, his heart began racing. He was excited to test the game out and he was not disappointed.

The Book of Fire slot is a 5-reel slot with 10 paylines. But the paylines are adjustable. You can choose to play with anywhere from 1 to the full 10 paylines. It boasts a reasonably high RTP of 96.02%.

The minimum bet value is low enough as is the case with so many online slots these days. You can start playing for as little as C$0.1. However, the maximum bet is capped at a rather low point as well. You can bet up to C$20. This can be both good and bad.

If you are one of those gamblers who can become too engrossed in the game and lose track of spending, a low maximum bet can be a helpful obstacle.

Besides, the maximum win from the Book of Fire slot has been reported to be C$250,000. So, who is not to like about a game with small bets and big wins?

Theme & Sound Design

Some would say the theme is inspired by magic and magicians’ tricks. While others would say that the theme revolves around alchemy. There is even a tinge of Harry Potter-like wizardry. You want to know what OJO thinks? OJO thinks that the theme is all of those things combined!

The Book of Fire slot brings together the world of witchcraft, wizardry, magic, and alchemy in a dark, mysterious, and exciting fusion.

The foreground of the slot grid is populated by a dimly lit room lined with shelves containing old books, magic potions, alchemical instruments, and so on. So, you can imagine the ambiance the creators of this game have tried to create.


Since the whole theme of the game revolves around witchcraft and alchemy, how can the symbols be any different?

All the special symbols are consistent with the theme. There is the wizard or magician symbol. And then there is a symbol for an own perched atop a stack of books. There are a couple of high-paying symbols representing alchemical equipment as well.

Getting any two of these symbols together can generate a winning payline.

Then there is the main Book of Fire slot symbol that functions as both the wild and the scatter symbols. You have to get at least 3 of them to trigger a winning payline.

As the wild symbol, it can substitute for all other symbols. As the scatter symbol, getting 3-5 of them together triggers the free games bonus feature.

The Book of Fire slot contains all the usual royal symbols as well. These are quite common across online slots and the Book of Fire is no different. These symbols include A, K, Q, J, and 10.

You have to get at least 3 of each royal symbol to trigger a winning payline.

Bonus Features

The noteworthy bonus features in this game include the free games round and the gamble feature.

Let’s start with the free games feature in the Book of Fire slot. It is triggered by getting 3, 4, or 5 of the Book of Fire slot scatter symbols.

Once you get 3 or more of the scatter symbols, you are awarded 10 free rounds. During these rounds, a special expanding symbol is chosen at random. This symbol expands to replace all the symbols in the reel. Thereby increasing the probability of generating winning paylines.

You can even win the maximum payout of 5,000x during this feature! That is if you get really very lucky. For example, if the highest-paying magician/wizard symbol is chosen as the special expanding symbol at the beginning of your free rounds.

Then, if you get one on each reel, the entire grid will become populated with the magician/wizard symbols. That will trigger the maximum 5,000x win!

The free games feature can also be retriggered. During the free rounds, you are awarded more free games every time you get 3 or more scatter symbols. This also increases the probability of big wins.

Moreover, a gamble feature can be used every time you win. This allows you to further increase your winnings. Basically, what you have to do is guess the color of the suit of a face-down card.

If you are correct, you get to double your winnings. However, if you lose, you lose the entire amount of your win.
