Mermaid’s Treasure Trove slot review
The mermaid on the cover smiles as if the pearl chest is already yours — standard genre courtesy, in a niche where sea maidens now outnumber the fish in the sea itself. But Pragmatic Play didn’t drop another five-reel line here: this is a 7×7 grid with clusters and cascades — the very kind that made Sugar Rush famous, only sunk to the seabed among the seaweed and shipwrecked galleons.
The base RTP is 96.54%, volatility is high, wins are formed by clusters of 5 or more matching symbols, and the ceiling sits at 10,000x the stake. The main intrigue is the wild multipliers, which don’t reset after a hit but climb from x1 upward by one per contribution, and during free spins stay sticky until the round ends.
How does this mermaid differ from her shelf-mates?
There are no paylines at all — forget about left-to-right winning rows. A cluster pays: five or more matching symbols touching side by side anywhere on the seven-by-seven field. Form a cluster and the symbols pop like bubbles, the ones above settle into the freed cells, and if the drop builds a new group, the cascade keeps going with no extra bet. The chain lasts as long as the field finds something to pay with.
The treasure theme isn’t mere decoration, yet it isn’t the lead actor either: pearls, shells and chests are simply an excuse for symbols of different value. Far more interesting is that this slot belongs to the cluster-pays family, mechanically akin to other cascading Pragmatic releases, but with its own trick up its sleeve — more on that below.
Why does the wild here know how to count?
This is what it was all built for. After any winning combination that didn’t involve a wild, a wild multiplier appears on the field with a modest x1. Then the curious part begins: every time that wild joins another win, its multiplier grows by one — x2, x3, x4 and onward. It’s not a one-spin gift but an investment that appreciates with every hit.
💡 Two multipliers that multiply each other
The slot’s strength lies in two breeds of multiplier working in tandem:
- Growing wild multiplier — starts at x1 and adds +1 per contribution to a win; the longer the chain lives, the fatter it gets;
- Symbol multiplier — paying symbols can drop with an attached random value from x5 to x100 (some sources put the floor at x2);
- The combo in free spins — here wild multipliers turn sticky and accumulate until the very end of the round, layering spin after spin — that’s where the threads to the 10,000x ceiling lead.
In the base game the potential is more modest — up to 150x on a lucky run. The real room opens up in free spins: they’re triggered by 3/4/5/6/7 scatters, granting 10/12/14/16/18 spins, and each new scatter along the way adds one more. And since the wild multipliers no longer reset between spins, by the round’s end the field can turn into a minefield — where every mine multiplies in your favour.
What return to expect from the growing sticky wilds?
The base RTP of 96.54% is a solid middle by Pragmatic standards, above many of its cascading peers. Volatility is high, and that’s no marketing word: the whole math is built around stacking multipliers, which means the field can stay silent for long, deliberate stretches between bonus runs. The 10,000x ceiling is a theoretical maximum reached only by perfectly stacked free spins with overgrown sticky multipliers; few ever see it in a real session, so it’s wiser to keep it as a reference point rather than a plan.
⚠️ Check the RTP version at your casino
Besides the base 96.54%, the slot circulates in operator builds at 95.56% and 94.54% — the gap between top and bottom is nearly two percentage points, and over distance with active feature buy it tells. Which version runs at your place is written in the game’s info window. If the value there is below the base, it’s simply a less generous edition; whether to play on it is for you alone to decide.
What players love
- A growing wild multiplier with no reset: x1 turns into a double-digit figure right within one living chain;
- Two multiplier types stack — a symbol value up to x100 on top of an overgrown wild gives genuine explosive upside;
- In free spins the wild multipliers are sticky and accumulate until the round ends — the bonus gains density rather than fading;
- The 96.54% RTP beats many cascading rivals, and the 7×7 grid leaves room for long tumbles.
What to keep in mind
- An RTP build down to 94.54% trims the return by two points versus the base 96.54% — especially painful when buying the bonus;
- Without free spins the base-game ceiling is only 150x — all the heavy artillery is locked inside the bonus round;
- High volatility means long empty stretches between runs — your bankroll needs to be built for a marathon, not a sprint;
- Super free spins at 400x the stake is a pricey entry, and the starting x10 doesn’t guarantee the chains will line up.
Who should dive in, and who should stay ashore?
| Player profile | Verdict | Why |
|---|---|---|
| Loves the "stack a multiplier, blow up the screen" mechanic | 🟢 Yes | Growing sticky wilds and symbol x100 are exactly that |
| A big-win hunter who tolerates variance | 🟢 Likely yes | The 10,000x ceiling lives in free spins with overgrown multipliers |
| Wants a steady session on a small bankroll | 🟠 Likely no | High volatility and a weak base stay silent between bonuses |
| Ready to buy super free spins at 400x without counting | 🟡 With caution | A pricey entry with no guarantee the multipliers grow in time |
⚡ Is Mermaid’s Treasure Trove worth playing?
This slot is justified in exactly one case: if the very idea of a multiplier that grows before your eyes and never resets — accumulating spin after spin during free spins until it explodes across the whole screen — is what excites you. Then 7×7 cascades with sticky wilds and symbol x100 are your element. But if you want a steady pace and predictable sessions on a modest bankroll, walk on by: high volatility and potential hidden inside the bonus mean a long wait at an empty field, and buying super free spins at 400x can easily become an overpayment for hope.

Frequently asked questions about Mermaid’s Treasure Trove
What is the RTP of Mermaid’s Treasure Trove?
The base build returns 96.54%. Alongside it, operator versions at 95.56% and 94.54% are in circulation — the exact value is shown in the game’s info window at your casino.
What is the volatility and max win?
Volatility is high and the ceiling is 10,000x the stake. This is a slot about stacking multipliers in free spins, not steady sessions: the field can stay silent for long stretches between bonus runs.
How do cluster pays work on the 7×7 grid?
There are no paylines: a cluster of 5 or more matching symbols touching side by side pays. After a win the symbols pop, the ones above drop down, and the cascade continues as long as the field forms new groups.
What makes the wild multipliers unique here?
A wild multiplier appears at a modest x1 and grows by +1 for each contribution to a win. During free spins these multipliers turn sticky and accumulate until the round ends, layering spin after spin.
Can you buy the bonus and how much does it cost?
Yes. Regular free spins open for 100x the stake, super free spins with a starting x10 multiplier for 400x. The ante bet (+50% to the stake) raises the trigger chance without a direct purchase.
Is there a free demo of Mermaid’s Treasure Trove?
Yes, the slot is available in demo mode with a virtual balance — you can feel out the cascades and the wild-multiplier build-up with no real bets before playing for real money.
