Mermaid’s Treasure Trove Slot Review
A violet-haired queen stands at the water’s edge gripping a golden trident, sunlight falling through the blue onto the broken columns of her drowned temple. In Mermaid’s Treasure Trove, from Pragmatic Play, the small pays are thin on purpose: everything on that 7×7 grid exists to feed one wild, and the game only really pays when that wild has been fed.
The headline maths: 96.54% RTP, medium volatility, stakes from 0.20 to 240 per spin, and a round cap of 10,000x the bet. Cluster-pay devotees will know the surrounding waters well, since Gems Bonanza and Sugar Rush swim on adjacent ground. The treasure here sits closer to the surface than the temple silhouette suggests.
Base Game & Features
Play unfolds on a 7×7 grid where symbols pay in blocks: connect five or more identical symbols horizontally or vertically and the block pays. There are no paylines in the traditional sense, just clusters, and every symbol in the game works this way. It’s a format Pragmatic Play has visited often, and the rules here are as clean as the format gets.
Winning symbols vanish and everything above tumbles down, with new symbols dropping in to fill the gaps. Tumbles continue for as long as new winning blocks form, and the lot is added to your balance once the chain ends. Scatters are the only symbols that survive a win.
The Paytable
Seven symbols carry the pays, and the ladder is steep. Values are multiples of your stake per winning block:
- Crown – 5: 0.75x, 6: 1x, 7: 1.5x, 8: 2x, 9: 2.5x, 10: 5x, 11: 7.5x, 12: 15x, 13: 35x, 14: 70x, 15+: 150x
- Treasure Chest – 5: 0.6x, 6: 0.75x, 7: 1x, 8: 1.5x, 9: 2x, 10: 4x, 11: 6x, 12: 12.5x, 13: 30x, 14: 60x, 15+: 100x
- Harp – 5: 0.5x, 6: 0.6x, 7: 0.75x, 8: 1x, 9: 1.5x, 10: 3x, 11: 4.5x, 12: 10x, 13: 25x, 14: 50x, 15+: 90x
- Horn – 5: 0.35x, 6: 0.35x, 7: 0.5x, 8: 0.75x, 9: 1.25x, 10: 2x, 11: 3x, 12: 5x, 13: 20x, 14: 40x, 15+: 80x
- Fish – 5: 0.3x, 6: 0.35x, 7: 0.5x, 8: 0.5x, 9: 0.75x, 10: 1.5x, 11: 2.5x, 12: 3.5x, 13: 15x, 14: 30x, 15+: 60x
- Starfish – 5: 0.25x, 6: 0.3x, 7: 0.35x, 8: 0.5x, 9: 0.6x, 10: 0.75x, 11: 1.5x, 12: 3x, 13: 3.5x, 14: 10x, 15+: 40x
- Shell – 5: 0.2x, 6: 0.25x, 7: 0.3x, 8: 0.35x, 9: 0.6x, 10: 0.6x, 11: 0.75x, 12: 1.25x, 13: 2.5x, 14: 5x, 15+: 20x
The gaps between tiers are the story. A five-symbol Crown block pays less than your stake back, while 15 or more connected Crowns pay 150x. Big money in this game means big blocks, and the tumble chains that build them.
Multiplier Wilds
The wild is the engine of the whole design. Whenever a winning combination lands that doesn’t already contain a wild, a Multiplier Wild appears in a random position inside that cluster. It starts at x1, climbs by x1 every time it forms part of a win, and shifts one position up, down, left or right after each tumble explosion. It stays on screen until every tumble from the spin has finished.
Wilds can also merge. Two or more wilds in the same winning combination combine into one, and their multipliers combine with them. Where a wild is shared across multiple wins, merges resolve in favour of the combination holding the most wilds, then the highest-paying symbol. On top of all that, paying symbols can land already carrying a random multiplier of their own.
Mermaid’s Treasure Trove Free Spins & Bonus Buys
Scatters trigger the feature, and the more you land, the richer the start. Hit 3, 4, 5, 6 or 7 Scatters anywhere on the grid and the round opens as follows:
- 3 Scatters – 10 free spins
- 4 Scatters – 12 free spins
- 5 Scatters – 14 free spins
- 6 Scatters – 16 free spins
- 7 Scatters – 18 free spins
The round changes one rule, and it changes everything: Multiplier Wilds stay on screen for the whole feature instead of clearing after each spin. A wild that triggers alongside the feature begins the round where it stood. That means a wild that survives and keeps winning can climb without limit across the entire round, and merged wilds carry their combined multipliers forward with them.
Every Scatter that lands during the round adds one extra free spin, and special reels are in play throughout. A round that reaches the win cap ends immediately, the win is paid, and any features still in progress are forfeited.
Ante Bet
There’s an ante option for players chasing a natural trigger. At the 30x bet multiplier, more Scatters sit on the reels and the chance of landing the feature naturally is three times higher; the bonus buys are switched off while it’s active. The default 20x multiplier is normal play.
Bonus Buys
Two buys sit under the reels, and the difference between them is bigger than the price gap suggests. Each guarantees a random Scatter count on the triggering spin:
- Buy Free Spins – 100x total bet, standard round
- Buy Super Free Spins – 400x total bet, wilds start at 10x instead of 1x
The Super version is doing the heavy lifting in that pricing. Four times the cost buys wilds that begin ten steps up the ladder, which in a round where they never leave the screen is a considerable head start.
Our Honest Verdict
Overall Rating: 7.7/10
Playing this is a long courtship with one wild. You sit in the queen’s sunlit ruins, watching modest blocks land and vanish while a multiplier quietly counts its way upward, and you stay because the free-spins round is where that patience gets paid. That’s the reason to choose it: nothing else in the game matters as much as a wild that’s been alive for six wins.
The free-spins round is genuinely good, because wilds that merge, persist and climb give a round a shape most cluster games can’t offer. The paytable underneath it is the letdown. Small blocks pay scraps, so a feature that never builds a serious wild can finish on almost nothing, and the best version of the round costs 400x to reach.
It suits players who enjoy the build more than the payout, and medium volatility keeps that build affordable. Anyone chasing immediate fireworks will find the water cold. The queen rewards patience, and this game is honest about expecting it.
