Book of Sirens

Book of Sirens Overview

Created by Spinomenal, Book of Sirens is an online video slot thematically based on the sea-dwelling sirens that appear in many a mythical tale. If you play your spins right here, though, you should make it to land with a boat full of treasure instead of being dragged down to your watery grave. Mechanically this is a five-reel, three-row slot with ten active pay lines. The maximum win available in this game is 5,000x the stake. This game operates a balanced math model and is played on a conventional win board that rewards players for matching symbols across the reels from left to the right.

The features for this game start with the wild feature, which concerns in this game the book icon. This symbol can replace any other symbol on the board to help score more wins. The book, however, is also the scatter icon and, when landed in combinations of three or more, triggers the free spin game, which rewards players with an instant cash win and ten free spins. The free spin round is a little more special than a regular free spin round as it also has an expanding symbol dynamic. Finally, this game also has a bonus buy option. All features will be explained in greater detail later on in the review.

Theme and Symbols

The theme for this game is a kind of generalised underwater mythology theme. At first glance, you might think that this game is just about sirens and their alluring beauty that lures sailors to their deaths. However, once you open the game, there is more of an Atlantis vibe with a whole underwater civilisation. Then you realise you can also see a strange green dragon and the mighty Kraken. What the designer has done here is collect anything you could reasonably assume has an underwater fantasy element and distribute it across the screen. Although effective, it does feel a little disjointed.

The background for this game is the glowing underwater city of Atlantis, or from what you can see, maybe just the outskirts of Atlantis. Interestingly, Atlantis (a city created by Plato) was described in his essays as an island larger than the country of Libya that went to war with Athens. Held up by Plato as an example of his Republic civilisation ideal, the story of Atlantis has informed many aspects of renaissance literature and is an important story in western philosophy.

The playing board for this game is a golden frame with a deep blue interior that contrasts starkly with the bright symbols upon it.
The symbols for this game are split into low-paying, high-paying and special symbols. The low-paying symbols are the 10, J, Q, K and A in playing card royals. The most valuable of these is the A which pays out at 15x the stake for the top combination. However, the more valuable symbols are the Kraken, the dragon, and the two sirens. The siren with the green hair is the most valuable symbol in the game, worth 500x the stake for the top combination. The special symbols in this game comprise only the book icon, which fulfils the roles of the scatter and wild.

Features

The first feature in this game is the wild feature. This feature concerns the book icon, which can substitute for any other symbol on the board, helping players score more wins.

The book icon is also this game’s scatter symbol. Land three or more of the books, and you will trigger the free spins game. Before you go into the special round, however, you will be awarded an instant cash payout. The number of scatters will determine the size of this payout that you landed to trigger it. The game awards ten free spins for three or more scatters landed.
Before you start the free spins, you are first taken to a bonus wheel. On this wheel are all of the symbols that appear during the base game minus the book icon. You will then spin the wheel. The symbol chosen by the wheel will then become the expanding symbol for the free spins round. This means that when this special symbol lands, it will expand to take over the reel that it is on. This helps players find more frequent wins.

Finally, this game also has a bonus buy option that allows players to buy their access to the free spins. However, this game is not available in the UK.

Conclusion

This game, you might say, is a very run-of-the-mill book of... slot with the same dynamics you might find in any similar slot. And yes, this is true, but at least this is a high-quality version of the genre with entertaining features, a decent win potential and a visually engaging theme. You might want to play it on demo first to get the hang of things, but the exposure isn’t too bad as long as you keep your bets small.
