Book of Poseidon Slot Review

If you thought SpongeBob was the only freak living under the sea, think again. Poseidon, the Greek deity who features as the central figure in Booming Games’ latest slot, was swallowed by his father, Cronus at birth. It was Zeus, Poseidon’s brother, who convinced papa dear to disgorge him.

I guess a troubling childhood like that explains why Poseidon had an epic temper. He is also said to have been a pig with women – and not even his granddaughter, Alope, was safe. So maybe he’s not the best character to base a game on, but nonetheless, here we are.

Apologies for starting things off like this, but facts are facts. Luckily, it’s all mythology to us so let’s see what Book of Poseidon slot has to offer.


Just as the name suggests, we’re floating deep in the sea with dolphins, octopi, and turtles to keep us company. Also bobbing around down there is a mysterious book with a sapphire on it, and of course, our trident-wielding homie, Poseidon.

The precious-stones-encrusted book is our overachiever here and serves as both the Wild and Scatter, while Poseidon is the highest-paying symbol.

If you’ve ever played a Booming game, you’ll be familiar with the layout. If not, look out for the “+” sign next to the SPIN button that pops out to reveal the Turbo, Max Bet, AutoSpin, and Sound/Music toggles.

Play the game vertically on your mobile phone, and you’ll see more of the underwater scene that Booming Games has so delicately crafted.

Within 7 spins of playing Book of Poseidon slot, I scored a Mega Win that brought in 160 credits. And almost as quickly, I lost it all. That’s the high volatility at play – fewer wins, but more robust ones when they do come in.

And there’s a lot to play for with this game: the max win could potentially swell your coffers by a substantial €250,000. Making that happen is the 5,000x multiplier, but the RTP barely squeaks past the cut-off for acceptability at 95.68%.

As far as the bet limits go, these start at €0.10 and increase to €50.


When it comes to the features of Book of Poseidon slot, you want to aim for landing 3 or more Wild Scatters. This unlocks 8 Free Spins and also scores you a cash prize that can range from 2x to 200x your stake.

Now, a random symbol is chosen to act as the Special Expanding Symbol for the duration of the feature. These pay no matter where they are on the grid, as long as you have a minimum of 2 matching major symbols, or 3 minor ones.

If the gods are indeed on your side, and you fill the grid with Poseidon symbols, that’s when you bag that elusive 5,000x multiplier.

If you’re able to score another 3+ Wild Scatters, you’ll retrigger this feature and you’ll also get another Special Symbol. Each retrigger gets you an additional 8 Free Spins and the upshot is that in theory, you can scoop an unlimited number of Free Spins in this game.

Lastly, we have the traditional Gamble Feature that gets offered after each win. You’ll need to choose whether the next card is red or black (for double your bet), or if you’re ambitious, you can guess the suit (for quadruple your bet).


As is befitting the god of the sea, storms, earthquakes, and horses (OK, that’s a weird addition), this slot plays perfectly on all devices and browsers.

Max Win

There’s a quarter mil up for grabs with Book of Poseidon slot! It’s not enough to buy a Platinum Arowana, but you could get a couple of freshwater Polka Dot Stingrays for your tank with that.


The selling points for this game are the unlimited Free Spins and the Special Expanding Symbols. Truth be told, neither of these is unique and unfortunately, they’re counteracted by the not-so-great RTP.

Besides judging this game on stats and features, the truth is that it’s not all that thrilling. The base game can get a bit tedious after a while, as that high volatility is a double-edged sword.

Wins just don’t come in frequently enough, and nor do the features, so you’ll be facing long stretches of not much action. So in summary, it’s pretty mediocre.
