Mermaid's Treasure Trove Slot Overview

Mermaid's Treasure Trove is a casino slot from Pragmatic Play, plunging players into the ocean depths to assist the beautiful mermaid in locating a secret spot filled with ancient treasures. She roams the underwater ruins of a mysterious city that bears marks of once-glorious civilization due to its elaborate architecture and riches that are hidden within its walls. Now, it lies on the ocean bed, available only to those who join the charming siren. Her powers of conjuring Wild bubbles with lucrative multipliers will let players stay submerged for extended periods of time so they can find their way to the bonus round, where Wilds never leave the grid. Once bubbles start combining and sharing their values, with the occasional assistance from regular symbols, the magical trove may burst open with fantastic wins reaching 10,000x the bet.

Mermaid's Treasure Trove Slot Information

The game's setting may be an interpretation of the City of Atlantis, given the magnificent structures nested on the ocean's bed. Majestic arches adorned with elaborate carvings and supported by massive columns stand still in the background, as if frozen in time, while the aquatic fauna slowly moves in and claims them for itself. Rays of sunshine pierce the water surface above, illuminating the entire scene and infusing it with an eerie atmosphere of loneliness. As is the slow, somber soundtrack played on string instruments. The only companion is the purple-haired mermaid watching over the grid where winning combinations must come in clusters of 5 or more matching symbols horizontally and/or vertically adjacent. She opens the underwater realm to all players who can join this aquatic adventure on a device like a desktop, a smartphone, or a tablet.

In the paytable, we find two sets of symbols responsible for creating regular wins. Low-paying ones take the form of a blue seashell, a green starfish, and a gold fish, paying from 20x to 60x the bet for a cluster of 15 or more units. High-paying icons appear as a horn, a harp, a treasure chest, and a crown, awarding between 80x and 150x the bet for matching 15+ in a cluster. Additionally, there are Wilds depicted by a blue bubble and Scatters represented by the image of the mermaid.

Cascading

The cascading feature, or tumbling, as Pragmatic Play calls it, comes into play each time you hit a winning combo on the reels. It results in winning symbols being blasted off the grid, which allows the remaining symbols to drop down and new ones to be added. This process continues until no new winning combos are formed.

Multiplier Wild

Whenever a winning combination gets removed from the grid, it leaves behind a Multiplier Wild with a value of x1. Any successive clusters involving that symbol during the same sequence will provide a further increase of +1 per win. After its contribution to the cluster, the Multiplier Wild moves into a random position. If two of them participate in the same win, they will merge and combine their values afterwards. Additionally, regular symbols may carry multipliers of x5, x6, x8, x10, x12, x15, x20, x25, x50, or x100, which will be added to Multiplier Wilds' value when they form a winning cluster together.

Free Spins

Scoring 3, 4, 5, 6, or 7 Scatters throughout the same spin awards 10, 12, 14, 16, or 18 free spins, respectively. Any Multiplier Wilds present on the grid during the triggering spin will be transferred to the bonus round. As the game progresses, all Multiplier Wilds, transferred or new, will be present on the grid until the end of free spins. Each Scatter landing during the bonus round awards 1 extra spin.

Mermaid's Treasure Trove Slot Conclusion

Isn't it strange that themes with a fantasy/mythological touch taking place underwater are usually extremely masculine or feminine? It's either Poseidon or a mermaid, with a kraken thrown in occasionally for good measure. Admittedly, after witnessing so many of those, there isn't much excitement in seeing another aquatic setting with a royally dressed beauty flapping its tail next to the grid. Sure, the overall quality of graphics is on a decent level, the background is quite immersive with its detailed ancient sunken city, and the soundtrack injects the scene with a mysterious vibe. That, however, doesn't change the fact that similar packages have been used repeatedly in online slots, so some unique elements that would make this one stand out would be welcomed.

When it comes to the mechanical side, the first sight of the bubbles with multipliers on the grid instantly brought to mind Blueprint Gaming's Rise of Atlantis. Although the association is incorrect. While visually it may be similar, Mermaid's Treasure Trove operates differently and is closer to the features seen in the X series from ELK Studios, like Katmandu X, where Multiplier Wild can merge into one symbol while combining their values. That's pretty much all this game is about. Score wins that leave behind Multiplier Wilds, and keep scoring more with their assistance to grow their values. Between cascades, they'll also move around the grid, exactly like in Jammin' Jars from Push Gaming. The bonus round sees all of them (both transferred from the base game and scored new) stick to the grid and continue their aquatic dance, occasionally merging into higher values. Also, regular symbols can lend a helping hand with carried multipliers that get added to the Wilds when they collectively form a winning cluster. All in, the config is quite functional in its simplicity and carries a decent win potential of 10,000x the bet.

Mermaid's Treasure Trove focuses its strength on a robust solitary feature of roaming Multiplier Wilds, which float in a generic and uninspiring aquatic environment.
