Mermaid’s Treasure Trove Slot Overview

Pragmatic Play dives into a shimmering undersea city with Mermaid’s Treasure Trove, a 7×7 cluster pays slot set among coral arches, pearl-lit ruins and glittering hoards.

The gameplay revolves around tumbling wins, roaming multiplier wilds that merge and grow, and a free spins round where those wilds stick around. It’s a bright, breezy take on the classic sea-life adventure with serious punch when multipliers line up.

Graphics & Theme

This one looks crisp. The gold-rimmed grid sits in front of a hazy, blue-green cityscape with columns, domes and drifting shoals. Symbols pop with lacquered colour—shells and starfish for the lows; harps, treasure chests and crowns for the premiums—and the mermaid companion floats beside the reels, flicking her tail as clusters burst.

Effects are tasteful: bubbles rise with each cascade, multipliers glow as they level up, and wins land with a satisfying, watery thud. The soundtrack leans into gentle strings and airy chimes, building subtly as tumbles chain together. It’s not flamboyant, but it’s polished and cohesive, and the multiplier animations give it just enough sparkle when things heat up.

RTP, volatility & max win

The default RTP is 96.54%. This is a high-volatility game, so results can swing from quiet stretches to sudden bursts when multipliers snowball. The maximum win is 6667x your bet.

How to play

1. Choose a stake from 20p and press spin.
2. Wins form from clusters of 5+ matching symbols; winning symbols are removed and new ones tumble in.
3. Keep an eye on multiplier wilds—each time they help a win, they grow and shift to a neighbouring tile.

Cluster pays & cascades

Every winning cluster clears from the 7×7 grid and triggers a tumble, allowing fresh symbols to drop for consecutive hits—classic cascading action paired with cluster pays math.

Multiplier wilds

After a win that doesn’t already include a wild, a multiplier wild drops into a vacant position at x1. Each time it contributes again, the value increases by +1 and the wild steps one tile in a random direction.

If multiple wilds connect in the same win, they merge and their values add up—great for building a single, hefty multiplier. Pay symbols can also land with multipliers (x5–x100); when they hit with a wild, those values are added to the wild. If no wild is present, one is created with the combined total. These are true wild multipliers and they persist through the whole tumble sequence.

Free spins

Land 3–7 scatters to trigger 10–18 free spins. Any multiplier wilds present on the triggering spin are carried into the round and stay on the grid until free spins end, growing as they keep contributing. Each extra scatter adds +1 spin. A Super Free Spins variant (where wilds begin at x10) may be available in some jurisdictions.

Mermaid’s Treasure Trove summary

Clean visuals, chunky symbols and a slick multiplier system make this underwater outing easy to sink into. The real juice is in how wilds snowball—merging values, absorbing symbol multipliers. It borrows familiar beats, but the execution is tight and the ceiling is generous. If you’re happy riding out dry spells for those big multiplier chains, this is a satisfying dive.
