Mermaids Treasure: Book of Pearls Hold and Win Slot

RTP and Symbols

The RTP is above 96% although Nucleus Gaming did not include it in its datasheet. The highest-paying symbols on the reels are the four mermaids.

The premium symbol is the golden mermaid. When 5 populate the reels, you’ll win 50x your stake or $10,000. A payout requires at least three matching symbols on the reels.

The low-value symbols are the card suits with mermaid scales. The rest of the symbols are the book scatter and the Bonus symbols with values.

Bonus Rounds

Hold and Win

The hold-and-win bonus game launches when 6 or more Bonus symbols appear. Each bonus symbol has a value from $0.03 to $40,000. You’ll see bonus symbols with gold, blue, and pink colors.

The blue and pink bonus symbols are the pricy ones. For example, the pink bonus symbol pays as much as $40K.

When the bonus round launches you’ll get 3 re-spins which resets to 3 with every symbol. When the bonus game ends it totals the value of each symbol for a final payout.

Free Spins

You’ll initiate the free spins feature when 3 Book scatters land at any position on the reels. The average free spin trigger is 40 to 50 spins since it’s a medium variance slot.

When the bonus game starts it awards 10 free spins and chooses an expanding symbol for you. I tested the buy option and played with a ten as the expanding symbol.

At an average stake of $8, I won $96 when I triggered the free spins using the Buy Option. To get the most out of the expanding symbol you need 3 or more across the reels.

They’ll expand on that particular reel awarding a substantial payout. You can also trigger the re-spins feature during the free spins feature. Moreover, you’ll gain extra free spins when 2 or more book scatters pitch.

They award anything from 2 to 10 extra free spins meaning that free spin retriggers are possible. As a parting shot, you can land a full screen of matching symbols on a single free spin.

Buy Option

Impatient? No problem. The buy option offers instant free spin triggers for 84x your stake. For casual players, 10 free spins will cost $8.40.

Tips and Strategy

Don’t go small when you play this slot to win money online since the betting range goes up to $20. Bankroll permitting wager at least $5 because you want to maximize your payout.

Test the game with free credits at the Nucleus Gaming online casino or visit their website. It’s the ideal slot to play with a bonus because it has plenty of special features.

Online casinos cap the maximum you can bet from $5-$10. High rollers don’t like to play with restrictions like that.

Verdict

Nucleus Gaming delivers a fine slot with Mermaids Treasure: Book of Pearls Hold and Win. The bonus games trigger quite easily and the potential for big wins is good.

The hit frequency is 30% offering a payout on every third spin. Usually slot games have something that keeps knocking me out of the game – it wasn’t the case here.

You can trigger the free spin or hold and win features within 50-60 spins. In theory, that won’t strain the budget too much.

It’s also one of those double-whammy casino games that swing both ways. I like the expanding symbol in the free spins since that increases your chances of catching a big win.

Root for the low-value symbol as an expanding symbol because it lands more often. Is there anything I did not like? Yes. I got plenty of low-value Bonus symbols in the hold and win feature.

That was the meh-part for me after testing the slot for 500 spins. The highest-value Bonus symbol I got was a blue symbol worth $160. More importantly, the value of the Bonus symbols is proportionate to your bet.

The higher your average stake per spin the better your chances of landing that elusive Pink peal worth $40,000. Lastly, for a full screen of Bonus symbols, I won $550.

When you accomplish a feat like that you’ll win the jackpot. Unfortunately, the hold and win feature does not include mini, minor, major, grand, or epic jackpots.
