Game Content

How good is the Book of Sirens by Spinomenal I hear you ask? Awesome! This is the fastest-winning game that I have ever played. Obviously, luck was on my side when I played this game.

I made the initial error of not noticing that my stake was 10€ a spin and didn’t notice until I’d hit the third spin. On my third and last 10€ spin, I bagged 3 scatter symbols which took me to the Bonus round and 10 Free spins. On my second Bonus spin, I bagged another 3 scatter symbols for another 10 spins, bringing my total to 20 Free spins. Cutting a long story short, that little Bonus round topped up my pot by a whopping 1,540€. At which point I stopped playing and cashed out 😊.

I know that luck is a fickle thing, but what a magical mermaid-laden start to a game set in Atlantis. I have played this game since and did win, but the casino I used took its revenge and I more or less gave it all back, obviously not all on the same game.

The Book of Sirens is a cool game even when you are not winning. The graphics and features as well as the soundtrack are typical Spinomenal, with just the right mix of imagery and gamesmanship all rolled into a single game.

That said, I am not sure it would have made my favourites list without the fabulous win, but it is a good game with a theme that isn’t tomb ridden.

The “Buy Feature” is available in this game, but like most other games with this feature, you risk a hefty 104x your stake for 10 “free” spins, with no guarantee that you will win as much as the stake has cost you. Once again, luck plays its part, but our top tip to you, is as always, to avoid this feature and play the game one spin at a time.

There is no safer gambling element other than the good old-fashioned manual click option. Which is good for me. There is no better way to control your game than a little willpower and an urge to play something else.

Game Developer

Spinomenal is a god among men when it comes to game development and graphical masterpieces. Everything they produce is an instant hit, even the quirkier games such as Book of Xmas and Donut Rush. The Book of Rampage is a great addition to an already impressive collection of Book slots.

Bonus Feature

Free Spins

The Book of Sirens is the next evolution in Spinomenals Book of… games. Obviously, this game is based around the classic scatter symbols that you’d normally get with any Book of… slot. Bag a minimum of three scatter symbols to trigger your 10 Free spins Bonus round.

The jackpots and wins on this game are really good, so good, and in my case virtually instant. Bag the scatter symbols in the good old-fashioned way, and this game comes alive. The pots are great and the animation is better.

Gamble Feature

There is no gamble feature on this game. There is a “go faster” button, but that just eats away at your funds and takes all the enjoyment out of the game.
