Book of Poseidon Slot – Free Demo

What Booming Games kept from the book format

Without background, the premise of Book of Poseidon might not halt you in your tracks. I put 400 spins through it at 5.00 a spin. It's a Booming slot at core with the recognizable setup displayed against an undersea backdrop, and unquestionably, Book of Poseidon does bear a similarity to the likes of other Book slots. Only the highest win on a payline is paid, and where a spin produces more than one win the amounts are added together. But what I get to test here is a fresh twist to the Book mechanics. Of those 400 spins, 86 returned anything at all, and 49 of those returned less than the 5.00 that bought them. What is accurate is that Booming Games does not squander time reinventing the wheel here. The help screen states the return to player as 95.7%.

An 18-spin gap on ten fixed lines

Just like most other slots of the Book lineage, Book of Poseidon is a 5-reeler, here with 10 fixed paylines that pay from left to right. The count is fixed, so you cannot switch lines off, and changing the stake rescales the paytable amounts. Now, hold a minute, is what experienced players might be pondering; that's a slim number of ways to get paid. The longest gap I hit without a win ran 18 spins and ended on spin 178. I've come to recognize contemporary slots as the thousands-of-ways monsters that they are. My balance peaked at 100,116.50 on spin 56.

The Wild Scatter and the gamble

In terms of features, there's some fresh and old to be found. Two of my 400 spins reached the free spins, on spin 35 and on spin 54. The gamble has been incorporated here as well, and I recognize it from earlier releases. Its theoretical return is 100%, so taking it does not move the game's RTP either way. Central to the game is the free spin feature with its Expanding Symbols and retriggers. Each trigger awards 8 free spins and picks one Expanding Symbol at random, and neither of my two rounds retriggered.

On the reels you will discover the Wild Scatter. It is also the symbol that opens the free spins, so the same icon does both jobs. It functions as a Wild and substitutes for everything except the Expanding Symbols. The two rounds I did trigger paid 270.00 between them, 28% of everything I won across the session. As noted before, you can expect to see the gamble come into play every now and then, and presented on base-game wins only, it's a double-or-nothing at 50% or a quadruple-or-nothing at 25%, with a 100% return and a ceiling of 500,000.00 on what it will gamble. A correct colour pays double the win, a correct suit quadruple.

The pick that decides the round

Players have to land 3 or more Wild Scatter symbols anywhere on the reels to trigger the bonus, and free spins are granted accordingly:

3 or more Wild Scatters in sight awards 8 Free Spins. In both of my rounds the count stayed at 8 and nothing extended it. It comes with one random Expanding Symbol. The pick is drawn at random from the symbols other than the Wild Scatter itself.

During the bonus, 3 or more further Wild Scatter symbols will award 8 additional free spins along with another Expanding Symbol. Neither of my rounds got there; both ran their 8 spins and stopped. There is no cap to how many times it can retrigger, up to 9 distinct Expanding Symbols. Reaching that ceiling needs nine separate picks, the one from the trigger and eight more found inside the round.

Players depend heavily on the Expanding Symbols for the biggest payouts, although the fixed paylines by themselves permit the chance to land big wins. Winnings awarded during free spins cannot be gambled, so whatever the round pays is what you keep. The Expanding Symbol covers all positions on the reels it lands on, so a single pick can cover the entire screen. Both of my triggers arrived early, 19 spins apart. I only partially got to test it first hand: across 400 spins at 5.00 a spin I triggered the bonus twice, and the better of the two paid 170.00, or 34 times the stake.

Minty Slots Verdict: Two triggers in 400 spins paid 270.00 between them, 28% of everything I won, and the ten fixed lines had to find the rest across 86 paying spins. The help screen states 95.7%; this run gave back 47.6% of what went through it.

What 400 spins returned

The second round paid 100.00, 20 times the stake, and I closed at 98,952.50 from a 100,000.00 start, having won 952.50 back off 2,000.00 wagered. My own 400 spins came back at 47.6% of what I put in.
