Mermaid’s Treasure Trove Slot Review

Mermaid's Treasure Trove is a New Slot from Pragmatic Play that invites you on a mesmerizing adventure to find the lost treasures of Atlantis. For many thousands of years, this ancient, advanced civilization sank along with an entire island, where its population had lived. Your guide on this incredible journey will be a charming mermaid who perfectly knows the way to the scattered chests full of gold scattered across the ocean floor. The Cluster Pays payout mechanic, as well as the Tumble and Multiplier Wild features, available in both primary and bonus modes, will allow you to collect plenty of mind-blowing rewards.

Launching this Mobile Slot immerses you at the ocean's bottom, where towering ancient structures from a once-prosperous civilization still stand. The vast yet elegant playing field (7x7) is crafted from gold and serves as a landing place for equally exquisite gold and gemstone decorations, which act as paying symbols. To make things ultimately lifelike, the slot is filled with animation, from the ocean surface rippling and schools of fish to air bubbles floating upward and seaweed swaying rhythmically. All these effects help you immerse yourself in the enchanting atmosphere of an unexplored underwater world, accompanied by a soundtrack that genuinely complements the game's vibe natively, which is both intriguing and mysterious.

Yet, the demonstrational mode offers the same gameplay as the real-money slot, allowing users to hone their skills and appreciate this game's highlights. When you're ready to play for cash, click the link above the "Play Demo" button to access the proven casino website.

Mermaid’s Treasure Trove - Base Game

Mermaid’s Treasure Trove Bonus Features

It’s a Cluster Pays Slot, boasting a huge 7x7-sized playfield. Winning combinations form out of 5-49 identical paying symbols, connecting each other horizontally or vertically. There are seven payout images, bringing cash prizes from x0.4 to x300, in this game.

Expert observation: This game’s paytable offers decent enough payouts to supply massive wins even during the base game. 

Tumble feature

This bonus feature initiates cascading wins, with symbols of all prize sequences disappearing after their payout. The empty rooms are immediately populated with new symbols falling from above, which gives a chance for new winning combinations to form. There is no limit to how many winning combos can form per round, which makes it possible to pile on decent wins during the primary gameplay, too.

Multiplier Wild Feature

The Multiplier Wild substitutes for all symbols, except for the Scatter, thus theoretically escalating the formation of winning clusters and boosting their prize amounts. The Wild appears exclusively as a result of cascading wins. Whenever a winning combination formed with no Wild participation disappears, a single Wild with a starting multiplier of x1 appears within an area of the recently disappeared winning cluster. Its multiplier gradually grows by one (+x1) each time the same Wild partakes in the following winning combination. Additionally, once it happens, the Wild makes a one-position move in a random direction within the area of the prize combination it's participated in.

Whenever two Wilds are part of the same prize sequence, they merge after the disappearance of the corresponding winning cluster, summarizing their multipliers. Note that paying symbols can additionally carry random multiplier values (x5-x100), appending them to the multiplier of the Wild that was part of the relevant combination. If paying symbols with multiplier values craft a Wild, its starting multiplier is the sum of the multiplier figures of these symbols. Multiplier Wilds don’t fade away within the whole respective spin’s duration.

Scatter

These special symbols trigger the bonus game that features Free Spins. The initial number of Free Spins depends on the number of Scatters collected:

Scatters

Starting Free Spins

3

10

4

12

5

14

6

16

7

18

Each Scatter caught during the bonus game brings a player a single extra Free Spin.

Trigger Free Spins Round

Free Spins (FS)

The only difference between the primary mode and the FS mini-game is that Multiplier Wilds persist in view until the end of all awarded Free Spins. By the way, all Multiplier Wilds created during the round that have triggered the current bonus game are transferred into Free Spins.

Mermaid’s Treasure Trove - Free Spins Round

Ante Bet

You can triple your chances of triggering the bonus game by enabling the Ante Bet function, which costs 200% of the bet. 

Buy Free Spins

Additionally, this Bonus Buy Slot authorizes you to trigger Free Spins forcibly. Starting the bonus game costs an amount that is 100 times your bet. In the case of buying, the random number of Scatters triggers the mini-game (3-7).

Buy Free Spins Option

Buy Super Free Spins

Additionally, any player can launch the Super Free Spin bonus mode (x400). During the improved bonus mini-game, each Wild will spawn with a x10 starting multiplier, instead of x1. Yet, the number of initially awarded Free Spins will still be random (10-18).

Mermaid’s Treasure Trove RTP, Max Win and Volatility

It’s a very High-Volatility Slot, boasting a pretty high RTP (96.54%). The winning frequency during the primary mode is 1 in 3.74 spins. The bonus FS game triggers approximately once every 431.52 rounds. Given the betting range (€0.2-€240) and the max win (x10,000), your most significant gain in this game can be achieved at €2,400,000. However, the maximum win awarding happens infrequently—roughly once every 66,666,667 spins. Fortunately, the x1,000 prize is more frequent, namely striking once in 57,035 spins.

Expert grasp: Be aware that this game possesses varying RTPs across different sites, from 96.54% to 94.54%. Therefore, be cautious when selecting a casino to play this game with cash. By the way, the best move is to choose online gambling venues from among the sites we recommend on GamblerID.com. It will save you time and guarantee that the selected venue is robust.

Our Experience Playing Mermaid’s Treasure Trove

Once the game’s rules were researched, we decided to experience playing the game on our own. The gaming balance was €200, while the bet per round was adjusted to €1. Last but not least, it was the Best RTP Slot (96.54%).

Unfortunately, we didn’t trigger Free Spins at all. Therefore, all our income throughout the entire gaming session is a result of ordinary wins earned in the base game. The first hundred spins generated as many as 35 cash prizes, ranging from €0.20 to €71.65. Eighteen wins appeared to be above the bet level (€1), including three decent gains: €71.65, €51.4, and €17.6. The most significant multiplier we reached was x32. Once the 100th spin was completed, our balance stood at €287.80.

The second hundred spins yielded 35 winnings, including 10 that exceeded the stake amount. This time, the largest catch was €23.05. The highest multiplier value achieved was x13. Only two gains exceed the €10 threshold: €23.05 and €13.70. After the 200th round, we had €255.9 in the account.

The ultimate hundred spins awarded us with three relatively substantial wins (€14.8, €12.15, and €11.15). The overall number of rewards was 22, with a maximum multiplier of x24. Yet, only seven prizes scored more than €1. When all spins were eventually over, our balance amounted to €221.80, meaning our net income totaled €21.80.

Key Takeaways

In this game, wins are quite frequent (1 in 3.3 spins), but most of our cash prizes turned out to be less than the bet (35 vs. 57). Multiplier Wilds and the Tumble feature are a wonderful mixture that enables you to both increase the number and amount of winnings. Moreover, there can be several Wilds on the playing field at once, which can unite, adding up their multipliers. All this leads to the base mode being capable of bringing substantial wins while waiting for the bonus game to start, which is triggered rarely (1 in 431.52 spins) but offers a convenient system of rewarding additional Free Spins—one free spin for each Scatter landed in view.

Expert tip: Use the Ante bet, which allows you to skyrocket your chances of activating Free Spins three times more, charging only 50% on top of the bet.

Mermaid’s Treasure Trove Strategy and Tips

There are a few recommendations each gambler should follow. 

Cherry-pick the Best RTP Slot

It’s vital to pick the best RTP version of this slot (96.54%) to elevate your winning chances. Please check the slot’s info section to confirm its actual figure.

Don’t Neglect Casino Perks

Bonuses are the best part of online gambling, as these Free Spins and extra cash incentives stretch your playing time, drastically increasing the odds of eventually winning a grand prize.

Expert tip: Pay attention to wagering requirements, particularly to the rollover coefficient, as it's believed that figures of up to x40 are the most comfortable to rollover.

Manage a Bankroll

Here is a concise list of the must-follow guidelines that will undoubtedly improve your gambling experience:

  • Split your account balance into multiple portions for separate gaming sessions, increasing your chances of beating the house at least once.
  • Divide each playing budget into a minimum of 450 rounds, given that bonus game frequency is one chance per more than 430 rounds.
  • Employ popular betting strategies used by seasoned punters.
  • Host loss, winning, and session time limitations.

Avoid a mixture of alcohol consumption and real money gambling.

Buy Free Spins

We bought Free Spins as many as three times:

Bonus Winnings

€100

€676.6

€1.35

The table above reveals a relatively low probability of profit when purchasing a regular bonus game. In our case, only one of three attempts was genuinely successful. Nevertheless, we will not draw a definitive conclusion as to whether it is worth spending money on purchasing a bonus game, leaving this decision to the player's discretion, as we eventually ended up with a profit of €488.75.

Buy Super Free Spins

We also bought three activations of the super bonus game:

This table shows that Super Free Spins offer a similar trend, with most launches of paid bonus games resulting in losses. However, this time, we also ended up with a profit of €271.2.

Don't Try To Win Back At All Costs

Last but not least, a piece of advice is to avoid trying to get income in each gaming session by chasing losses every time, as this is a short way to severe financial issues. Gamble responsibly, treating slots as entertainment, not a means of income. 

Our Verdict

Concluding this slot review, Mermaid’s Treasure Trove is an eye-catching game that involves you in the mesmerizing process of seeking the treasures of an advanced civilization that disappeared thousands of years ago in the ocean depths. Naturally, such an adventure seems highly intriguing due to the adrenaline-pumping plot and incredible wins eligible via Multiplier Wilds that spawn as a result of cascading wins. Of course, the unlimited growth of their multipliers contributes to the excitement, and their occasional roaming across the playfield and merging make the gameplay dynamic. Free Spins, where Multiplier Wilds' multipliers don't reset between rounds, further enhance the players' thrill.

Yet, first you need to wait until the bonus game starts, as the FS Round triggers only once every 431.52 spins, which is quite rare. As a result, due to the high volatility, it's possible to deplete one's balance even before encountering a substantial win. Sure, you can downsize your stake amount, yet, in this case, you couldn’t enjoy mouthwatering gains. In our expert opinion, this game, with its maximum win of x10,000 and extreme level of volatility, is more suited for high rollers and especially those who have a fondness for mermaids and love to watch the ocean depths.

Expert advice: If gameplay with cascading wins and growing multipliers is what makes you cheer up, here are a few games that undoubtedly would diversify your gambling experience: Fire Portals (max win: x10,000, RTP: 96.06%, volatility: Extreme), Sweet Rush Bonanza (max win: x5,000, RTP: 96.5%, volatility: Very High), and Gates of Olympus (max win: x5,000, RTP: 96.5%, volatility: High).
