There are thousands of online slots, yet sometimes it feels as if the entire industry…
Mermaid’s Treasure Trove
Thu Oct 2, 2025
Take a deep breath, because Pragmatic Play is inviting players to dive beneath the waves in Mermaid’s Treasure Trove, a slot that mixes cluster pays with multiplier-packed wilds. Imagine the mechanics of Fire Portals, only this time submerged in an ocean kingdom where glowing symbols cascade across the grid, multipliers swell, and treasures surface from the seabed.
Design & Theme
Mermaids, underwater palaces, and a touch of mythical charm – that’s the setting here. A golden-framed grid sits in front of a sunlit seabed, with grand structures in the distance. A mermaid floats at the side of the reels, watching as clusters pop and symbols tumble. It’s colorful and pleasant, if not particularly groundbreaking – more in line with the familiar “azure underwater world” slots we’ve seen before.
Game Setup
The action plays out on a 7×7 grid using the cluster pays mechanic. Any group of 5 or more matching symbols triggers a win, exploding to make way for new symbols via tumbling reels. As long as clusters keep forming, the chain reaction continues.
The math model is highly volatile, paired with a 96.54% RTP. Betting starts at €0.20 per spin and can climb up to €240. An ante bet option is available, boosting free spin chances at the cost of a 50% higher stake.
Paytable
Symbols range from small sea creatures to royal treasures. Low-payers include shells, starfish, and fish, while premiums cover horns, harps, treasure chests, and crowns.
- Clusters of 5 symbols pay between 0.2x – 0.75x the stake.
- Large clusters of 15+ symbols deliver 20x – 150x the bet.
Multiplier Wilds
Wilds are the backbone of this game. They substitute for all regular symbols (except scatters) and come with multipliers.
- When a cluster is cleared without a wild, a x1 wild appears in the empty spot.
- Each time it’s part of a win, the multiplier increases by +1, and the wild moves to a new position.
- Multiple wilds merging? They combine into a single one, keeping the total multiplier.
- Regular pay symbols can also land with multipliers ranging from x5 to x100, which can be added to wilds.
Wilds remain in play during tumbles until no new wins occur.
Free Spins
Scatter symbols unlock the main bonus:
- 3, 4, 5, 6, or 7 scatters = 10, 12, 14, 16, or 18 free spins.
- Wild multipliers stick on the reels for the entire round.
- If multipliers were present on the triggering spin, they carry into the feature.
- Extra scatters award +1 spin each.
Feature Buy
Players can shortcut into the action with two buy options:
- Free Spins for 100x bet.
- Super Free Spins for 400x bet, starting with wilds already at x10 multipliers.
Treasure at the Ocean’s Heart
Mermaid’s Treasure Trove doesn’t reinvent the wheel, but it does know how to keep the reels flowing with tension. The shifting wilds, the merging multipliers, and the sticky free spins bring enough life to make the ocean floor shimmer.
Where the game really glimmers is in those rare moments when multipliers snowball into something huge, especially with super free spins kicking things off at x10. Add in the potential for 10,000x max wins, and the mermaid’s domain might just reward those willing to plunge deep enough.
In the end, this slot feels like a chest hidden in the seabed: the outside may seem familiar, but open it, and there’s a chance to uncover riches worthy of the ocean’s queen.
