This new product is characterized by bright colors, as well as good detail - all this thanks to the three-dimensional visualization of characters. The role of the background image went to a crystal clear reservoir, as well as a variety of algae to corals. The slot uses such values ​​as dolphin, octopus, Poseidon, turtle, as well as denominations of playing cards from ten to ace. During the formation of a combination, animation special effects are triggered, while the winning icons move. The gameplay is accompanied by heroic music.

The RTP percentage in the Book of Poseidon slot is 95.68%. Game actions take place on 5 reels placed on a 5x3 grid. The client also receives 10 ways to create winning chains.

The Book sign here acts as a wild and a scatter at the same time, while bringing separate rewards. The highest payout of this machine exceeds the current bet by 5,000 times.

There are several options in the main game:
free spins. To trigger this bonus and get 8 free spins, you need to hit at least 3 scatters. In addition, the player is awarded x200, x20 or x2 for 5, 4 or 3 triggering scatter symbols respectively.
Expanding Symbols. An image is randomly selected to expand during the free spins. After the free spins are activated again, an additional special symbol can be selected - this allows you to transform up to 9 icons into Expanding Symbols.

The manufacturer Booming Games decided not to add a bonus level, so all hopes are placed on free spins with expanding symbols in the main game.
