Bonus Features
The game shines with its bonus offerings, perfectly capturing the alluring mermaid spirit. Dive into the rest of our Mermaid’s Pearl slot review to uncover the workings of these enticing features. The treasure chest scatter symbol is the gatekeeper to the game’s bountiful free spins feature.
Landing 3 or more scatters not only grants a generous amount of up to 60 free spins but also opens the possibility of retriggering the feature for even more spins. These bonus rounds play at the current stake, making every free spin a chance to amass the treasures of the deep without additional cost. The game also includes a Gamble feature, where you can win big or lose your winnings, depending on your stroke of luck.
RTP & Volatility
Mermaid’s Pearl RTP is 95.21%, which is below average for online slots. This indicates a less than fair return to players over time. The game’s high volatility ensures that while wins may not occur on every spin, they have the potential to be significant when they do materialise. This high-risk, high-reward setup is sure to attract players looking for the thrill of chasing big wins.
Symbols
The symbols adhere to the underwater theme with lower-value icons represented by the traditional 9, 10, J, Q, K, and A, all styled to fit the aquatic motif. Higher-value symbols include an assortment of sea creatures like blowfish, turtles, and seahorses, which bring the ocean to life on the reels.
The mermaid symbol is wild, substituting for all symbols except the scatter, doubling wins when substituting, and the treasure chest acts as a scatter to unlock the game’s free spins.

Prioritise activating as many paylines as possible to increase your chances of winning combinations, and keep an eye out for the high-value symbols that can boost your payout significantly.
How to play Mermaid’s Pearl
Playing this game is straightforward: set your bet and spin the reels. Use the Autoplay feature for a hands-off approach, and explore the paytable for a deeper understanding of the game’s mechanics. The gamble option presents a chance to double your prize, but it comes with the risk of losing the wagered amount if the gamble fails.
SlotsCalendar tips: Before diving into the gamble feature, assess your current standing. If you’re ahead, it might be worth taking a calculated risk. However, if your bankroll is low, it might be wiser to secure your winnings and continue spinning the reels.
