How the Book of Immortals bonus works

Like the vast majority of slot machines, Book of Immortals offers a bonus feature in which free spins are offered to you. 10 free spins will be awarded if you see at least 3 scatter symbols. The latter is represented by a mysterious blue book with a beetle on it.

In addition to the free spins, this symbol also allows you to win. If 3 books appear, you win 2x your bet, 20x for 4 books and 200x for 5 books.

The Book of Immortals Bonus works like most Book of slot machines, i.e. a symbol will be randomly selected and will be your reference symbol during all free spins. This symbol will be expandable throughout the entire reel, which will significantly increase winnings, and connections will take place even if the symbol in question is not present on the paylines.

Each time a connection is made with the reference symbol, the symbol changes and is replaced by a new symbol, which is present in the middle of an additional line at the very top of the slot.

If a premium symbol becomes a reference symbol and connects, then it will be expandable during all free spins. You have the possibility to recover free spins if a book appears in the middle of the top row.

Our opinion on Book of Immortals

Book of Immortals is an astonishing and very successful slot machine from the iSoftBet provider, due to its original graphics but also its atypical functionality. Indeed, the Book of Immortals bonus differs from other slots stamped "Book of" and makes this online game stand out from the competition.

The low popularity of Book of Immortals is undoubtedly due to its low volatility. Nevertheless, the gaming experience offered by this provider is more than correct and nice winnings can still be made.
