Book of Sirens: How it works

Even if you've never played an online slot before, Book of Sirens will be very easy to get started with. The structure is self-explanatory, as are the game's controls. Spinomenal sticks to a very traditional structure here. This means that the slot is played on a total of five reels with three rows each. This means that 15 winning symbols can appear on the reels at the same time in each round. For these to yield a win, you have to combine several identical symbols on one of ten active win lines. The number of win lines is fixed at ten and cannot be changed.

Below the reels, you can set your stake per payline with a click of the mouse. At least €0.01 must be wagered per payline, resulting in a minimum bet of €0.10 per reel spin. A maximum of €10 per payline, i.e. €100 in total, can be placed for the round bet. Before you set the reels in motion, you can take a look at the game's paytable. The corresponding button is indicated by the small question mark under the reels.

You then have two different options for the roller rotations. On the one hand, you can do this manually. On the other hand, these can also be processed using the autoplay function. In this case, the slot performs the reel spins automatically and you save yourself the individual clicks for the game rounds. Not to be overlooked here is the buy feature for purchasing the bonus rounds. However, we will go into this in more detail later on.

Book of Sirens winning symbols

To give you a precise overview of the individual winning symbols, we have listed them below together with their winnings:

  • Card game symbols
  • Purple dragon
  • Green dragon
  • Red-haired siren
  • Siren with headband
  • Scatter Wild symbol

Card game symbols

With the card game symbols from the 10 to the A, traditional winning symbols can be found in the Book of Sirens slot. In the case of the 10, the J and the Q, the winnings here are identical. If these appear three times on a win line, you receive five times your line bet. With a stake of €0.10 per win line, you would receive €0.50 back for three of these symbols. If it appears four times, the win increases to €2.50, meaning that you receive 25 times the line bet. If these symbols even appear five times on a win line, you collect 100 times the payline stake. At €0.10, this would be €10.

If you can combine the K or A on the win lines, the winnings increase a little. If they appear three times, they are still identical. So here you can win five times your line bet. If four appear on a win line, you collect 40 times the amount, which would already correspond to four euros with a stake of €0.10 per win line. If the K or A appear five times on a win line, you can win 150 times the line bet.

Purple dragon

The two dragon symbols offer even more winning opportunities. Both pay out a win if they appear twice on a payline. If these appear twice on a win line, you can look forward to five times the line bet. With three purple dragons it is 30 times the line bet, with four symbols 100 times and with five symbols 750 times.

Green dragon

The winnings with the green dragon are identically high. Here, too, you get five times the round stake back if three appear on a win line. A triple appearance increases the payout to 30 times the stake, a quadruple appearance to 100 times the stake and a quintuple appearance to 750 times the stake.

Red-haired siren

The red-haired siren will also reward you with a prize if you appear twice. With two symbols, this is five times your line bet. If the red-haired siren appears three times on the line, you receive 40 times the round bet; if it appears four times, you receive 400 times the round bet. If you can even combine five of these symbols on a win line, the payout increases 2,000-fold.

Siren with headband

The siren with the headband increases the gains even further. Here you get ten times your line bet back if you appear twice on a win line. With a triple appearance you can increase the winnings to 100 times the stake, with a quadruple appearance it is 1,000 times the stake. If the siren with the headband lands five times on a win line, the slot rewards you. 5,000 times your line bet.

Scatter Wild symbol

The most important special symbol in this slot is the book with the sparkling pearl on the cover. This appears as both a scatter and wild symbol. In other words, the book can substitute for missing symbols on a win line as a wild symbol. If three of the books appear in any position on the reels, this scatter also triggers the free spins round.

Features and special features

Which brings us to the next topic surrounding the Book of Sirens slot. The features and special features. With the free spins and the Bonus Buy feature, you will find two major and important features here. We will explain exactly what these are in detail below.

  • Free spins
  • Bonus Buy Feature

Free spins

Anyone who has already played a few rounds on various slots will be very familiar with the free spins mechanic in Book of Sirens. But first things first. You can trigger the free spins in this slot with at least three books. These must be in any position on the reels to activate the free games as scatters. Important: The number of scatters is not decisive for the number of free games. In any case, you will be credited with ten free spins. Within the free spins, you can trigger additional free spins with three or more scatters.

A bonus symbol is determined in advance for the free games. In future, this will appear as an expanding symbol. As soon as this lands on a reel, all positions on the reel are converted into the corresponding symbol. In the best case scenario, you can fill all reel positions in the game with the identical winning symbol.

Bonus Buy Feature

It may take a few rounds of Book of Sirens before the free spins start. If you want to save yourself this time, you can take advantage of the Bonus Buy feature. With this feature you can simply buy the free spins. To do this, press the corresponding button below the reels. You can then buy 10 free spins, for which you will have to pay 104 times your current round stake.

Alternatives

If you're looking for possible Book of Sirens alternatives, you'll quickly find what you're looking for. We have selected three of the best and most popular alternatives for you below.

Book Of Ra Magic

Most players are familiar with the title Book Of Ra. But what about Book Of Ra Magic? This is a further development of the Novoline classic, which can be described as the absolute top alternative to Book of Sirens. You are also hoping for at least three books to activate the free spins. The special feature: If three more books are added to the free spins, an additional bonus symbol is also selected. In the best case scenario, you can use up to nine bonus symbols!

Book of Magic

Another attractive alternative is the slot Book of Magic, which was developed by EGT. What's special here: You can benefit from features in two different ways. One is the book of magic and the other is the scatter crystal ball. This triggers 15 free games, the number of which can be increased by further scatters in the free games.

Book of Dead

In Book of Dead, you can go on a journey of discovery with the famous adventurer Rich Wilde. The focus is on hidden treasures of antiquity. You can only discover them with the help of the legendary Book of Death. If this appears three times on the reels, you trigger the free games as in Book of Sirens. The fact that one of the symbols is selected as a bonus symbol with an expanding function for the free games is also identical.

Play Book of Sirens online – our conclusion

Those who rely on more classic principles and mechanics will have pure joy with Book of Sirens. Spinomenal ‘s title takes up a bonus feature that has been popular for many years with the free games and the expanding wild. A modern influence is particularly noticeable in the Bonus Buy feature. In our opinion, it is a very entertaining slot that is suitable for almost every player. The betting options from €0.10 to €100 per round underline this.

Advantages:
  • Bonus Buy Feature
  • Free spins with expanding bonus symbols
  • x50,000 as the maximum win in the Free Spins
Disadvantages:
  • No progressive jackpot
  • Only one real feature with the free spins
