Mermaid's Treasure Trove Game Review (New Slot Demo).
Introduction to Mermaid's Treasure Trove
Mermaid's Treasure Trove from Pragmatic Play launched 2nd October 2025, and I've been diving into this underwater adventure for some days. As someone who's played hundreds of cluster pays slots over the years, I was curious to see how Pragmatic would handle the underwater theme with their signature mechanics. The game features a beautiful mermaid floating beside a 7×7 grid surrounded by ancient underwater temples and that typical azure mystique you'd expect from an ocean-themed slot
You can now play the free slot by simply clicking the demo game above and start playing.

Gameplay and Special Features of Mermaid's Treasure Trove
Mermaid's Treasure Trove uses a cluster pays system on a 7×7 grid, meaning you need 5 or more matching symbols connected to form wins. When you hit a winning cluster, the symbols burst away and new ones tumble down, potentially creating chain reactions that keep the action going.
The main attraction here is the Multiplier Wild system. When you clear a win without a wild, a multiplier wild drops into an empty space starting at x1. Every time this wild contributes to a win, its value increases by +1, then it randomly moves one position on the grid. The really interesting part is when multiple wilds are part of the same win – they merge together, combining their multipliers into one super-charged wild.
Pay symbols can also land with multipliers ranging from x5 to x100. If they're part of a win with wilds, their values add to the wild multiplier. If there's no wild present, a new one gets created with the combined value. These multiplier wilds stick around through all the tumbles until your spin ends.
Free Spins and Bonus Features
The free spins trigger with 3-7 scatter symbols, awarding between 10-18 spins depending on how many scatters you land. The game-changer here is that multiplier wilds don't disappear between spins during the bonus – they stay on screen for the entire round, moving around and merging as they contribute to wins.
If you happen to have multiplier wilds on the screen when you trigger free spins, they carry over to the bonus round in the same positions, which can give you a nice head start. During the feature, each additional scatter you land adds +1 free spin, helping extend those potentially massive multiplier builds.
The super free spins option (available through the bonus buy for 400x) is where things get really exciting. Instead of wilds starting at x1, they begin at x10, giving you a huge advantage from the very first spin.
You can buy the regular free spins for 100x or super free spins for 400x your bet. There's also an ante bet option that increases your chances of triggering free spins but costs 50% more per spin.

My Thoughts About This Demo Game™
After serius testing, I can say the free spins and especially the super free spins are really fun to play. I got many extra free spins in the super bonus, and I love when the multipliers melt together and combine – watching those values stack up creates genuine excitement.
The base game is decent but nothing spectacular. You get occasional wild multiplier action that keeps things interesting, but it's really just a warm-up for the bonus rounds. The high volatility means you can go long stretches without hitting free spins (1 in 432 spins on average), so patience and proper bankroll management are essential.
What really impressed me during the free spins was how the persistent wilds build momentum. They bounce around the grid, merging with other wilds and accumulating substantial multipliers over the course of the feature. Combined with those pay symbols that can land with x5-x100 multipliers, the winning potential becomes very real.
The super free spins are definitely worth the 400x cost if you've got the bankroll for it. Starting with x10 wilds instead of x1 makes a massive difference in your potential outcomes. I've had some incredible runs where multiple x10 wilds merged together and combined with high-multiplier pay symbols for wins exceeding 1,000x.
However, I do have some criticisms. The theme feels a bit generic – it's pretty but nothing we haven't seen dozens of times before in underwater slots. The merging mechanic, while mathematically sound, sometimes feels counterproductive. There were moments I wished the wilds would stay separated and spread across the grid rather than combining into one position.
The 10,000x max win is respectable but not earth-shattering by today's standards. With a max win probability of 1 in 66 million, you're more likely to hit consistent medium-sized wins than chase that ultimate jackpot.
Bottom line: Mermaid's Treasure Trove delivers solid cluster pays action with an engaging multiplier wild system. The free spins can produce exciting results, especially the super version, but the game lacks that special spark to make it truly memorable in a crowded market.
🎯 Overall Rating: 8.4/10 – A well-crafted slot that does everything competently without quite reaching greatness.
Will I play again? Yes, but it will not be one of my favourites.
