About Book of Poseidon

This is an extremely volatile slot with a slightly below average RTP of 95.68%, The game area consists of 5 reels, 3 rows and 10 winning ways. Bets range from 10p up to £20 per spin and is optimised to play across desktop and mobile devices.The design is inspired by Poseidon, the Greek God of the sea. The reels sit on a backdrop of an underwater kingdom filled with plants and colourful corals. On the reels are the low pay 10-Ace royals, and high paying symbols are a dolphin, an octopus, a sea turtle and Poseidon himself, the latter is the most valuable awarding 500x for 5 on a payline. As with all “book” slots, the book symbol acts as both the scatter and wild.

Gameplay

The game only has one special feature, and this is central to the book symbol. To activate the bonus round you at least 3, 4 or 5 book symbols to receive 8 free spins and a 2x, 20x or 200x the bet respectively.Before the free spins begin, a symbol is randomly chosen to transform into an expanding symbol. Landing 3 or more scatters re-trigger the bonus round awarding an additional 8 free spins. Another special symbol is then selected on each re-trigger.Matching symbols payout regardless of where they appear on the reels. To land a winning combination you ‘ll need at least 3 of the low paying symbols or just 2 of the high paying symbols. If you are lucky enough to fill the grid with Poseidon symbol the top prize of 5,000 of your bet is awarded.

Verdict

The design is a standard Book slot. The action heats up in the bonus round, but it depends on how many special symbols you get and how many retriggers, for a crack at the top prize of 5,000x the bet
