Mermaid’s Treasure Trove (Pragmatic Play) Slot Review

Mermaid’s Treasure Trove: Slot Overview 

Dive deep beneath the shimmering blue waves and explore a world of treasure, magic, and multiplier mayhem in Pragmatic Play’s Mermaid’s Treasure Trove, a beautifully rendered underwater slot that merges classic cluster mechanics with exciting modern twists. Released on October 2, 2025, this title invites players into a luminous ocean realm where glimmering coins, shells, and crowns cascade across a 7×7 grid, and wins form through cluster pays rather than paylines. 

On paper, Mermaid’s Treasure Trove shares DNA with Pragmatic Play’s earlier title Fire Portals, offering similar tumble mechanics and multipliers. But the difference lies in its theme and mood. This is a more tranquil experience, bathed in hues of gold and sapphire, buoyed by a relaxed rhythm that mirrors the sway of the sea. Underneath that calm surface, though, lies a high-volatility math model capable of unleashing wins up to 10,000x the bet — a treasure haul worthy of the mermaid’s vault itself. 

With a 96.54% RTP, 1 in 3.74 hit frequency, and free spins appearing roughly once every 431 spins, this slot strikes a familiar Pragmatic balance between playability and big potential. It’s a game designed to dazzle visually and reward persistence — if you can hold your breath long enough to uncover its secrets.

Design and Graphics 

Mermaid’s Treasure Trove is one of Pragmatic Play’s most visually immersive underwater releases to date. The action unfolds against a breathtaking seascape of aquamarine light, coral formations, and ancient ruins, evoking an undersea world rich with history and myth. Columns and temple spires rise from the sand in the background, hinting at lost civilizations, while faint rays of sunlight ripple through the surface above, illuminating the reels with a soft, hypnotic glow.The mermaid herself floats gracefully to the right of the reels — her flowing violet hair and shimmering scales designed with a painterly attention to detail. She serves more as a thematic anchor than an active symbol, yet her presence adds personality and allure to the overall scene. 

Symbols themselves gleam like artifacts of the deep: shells, starfish, golden fish, harps, treasure chests, and crowns. They’re arranged on a gold-rimmed 7×7 grid that sparkles whenever wins occur, sending clusters bursting in cascades of bubbles and color. The higher the payout, the more vivid the effects — with multiplier wilds lighting up the screen in glowing blues, purples, and golds. 

Pragmatic Play has always excelled at visual polish, and this title continues that tradition. The art direction balances elegance and accessibility, ensuring that even during the most chaotic tumble sequences, the screen remains readable and visually harmonious. It’s a game that looks as good in motion as it does in screenshots, and its serene atmosphere helps offset the volatility lurking beneath.

Gameplay Mechanics 

At its core, Mermaid’s Treasure Trove uses a cluster pays system on a 7×7 grid, meaning wins occur when five or more matching symbols connect horizontally or vertically. Every winning cluster triggers a tumble mechanic, where the winning symbols vanish and new ones drop in from above, allowing for consecutive cascades on a single spin. 

This cascading feature is key to the game’s rhythm — as clusters disappear and reform, the potential for compounding wins grows. It’s possible to chain together multiple hits in one turn, especially when multiplier wilds begin to appear and enhance payouts. 

Bets range from €0.20 to €240 per spin, offering a wide spectrum of options for casual and high-roller players alike. The Ante Bet can be activated at the cost of a 50% higher stake, which increases the likelihood of triggering the free spins feature — a smart option for those chasing bonuses. 

The RTP peaks at 96.54%, which is competitive for a high-volatility game. As with most Pragmatic Play titles, the action can swing dramatically between small cascades and exhilarating multiplier runs. The design encourages patience: smaller base wins are frequent enough to sustain gameplay, but the real treasures lie within the game’s feature rounds.

Sound and Music 

Sonically, Mermaid’s Treasure Trove complements its oceanic visuals with a calming, melodic soundscape. The background score features soft harp tones, echoing chimes, and gentle currents of ambient synth, creating the sensation of floating underwater. 

Each spin is accompanied by subtle “bubble pop” effects, while cascading wins produce an ascending shimmer of sound — a satisfying auditory cue that mirrors the rush of rising bubbles. When multiplier wilds land, their appearance is punctuated by a richer tone, adding both clarity and anticipation. 

During the free spins round, the music grows more dynamic, layering orchestral swells over the ambient score to heighten excitement without losing its tranquil character. The mix of calm and intensity mirrors the gameplay’s ebb and flow — moments of serenity followed by bursts of thrilling energy. It’s understated yet effective sound design, aligning perfectly with the game’s aquatic theme.

Bonus Features 

The heart of Mermaid’s Treasure Trove lies in its multiplier wild system and its two-tiered free spins mode. These interconnected features transform ordinary cascades into thrilling chain reactions capable of building toward enormous payouts.Multiplier Wilds 

Multiplier wilds substitute for all symbols except scatters. When a winning combination clears and leaves a gap, a multiplier wild may drop into one of the empty spaces, starting with a 1x multiplier. Each time it contributes to a win, its multiplier increases by +1, and the wild shifts one space in a random direction before the next tumble. 

If multiple wilds appear within the same cluster, they merge into a single wild, combining their multipliers. For example, two 5x wilds can merge into a 10x wild, amplifying potential significantly. This merging mechanic brings strategic unpredictability to every tumble — sometimes creating a single powerhouse wild that can dominate the screen. 

Regular pay symbols that participate in a win with a wild add their own multipliers to the total, producing massive chain reactions. Wild multipliers can range from 5x to 100x, persisting through tumbles until the end of the spin sequence. It’s a mechanic that adds tangible suspense to every cascade, as players watch wilds drift and evolve like sentient treasures. 

Free Spins 

Landing 3, 4, 5, 6, or 7 scatter symbols triggers 10, 12, 14, 16, or 18 free spins, respectively. During free spins, all multiplier wilds that appear remain sticky until the feature concludes, maintaining their positions and values. 

If multiplier wilds are already on the grid when the round begins, they carry over, setting up the potential for a head start. Each scatter that lands during the feature awards +1 additional free spin, prolonging the round and expanding opportunities for wild growth. 

This persistence mechanic turns free spins into an escalating frenzy of wild merges and high-value clusters. It’s an excellent demonstration of Pragmatic’s mastery of tension and release — a slow build followed by explosive payoffs. 

Feature Buy 

For players who prefer immediate action, Mermaid’s Treasure Trove offers two Feature Buy options:Standard Free Spins: Costs 100x the bet, triggering the regular feature. 

Super Free Spins: Costs 400x the bet, starting the round with all wilds initialized at x10 multipliers instead of x1. 

The super variant is especially lucrative for those chasing the game’s full 10,000x potential, though it carries the high-risk price tag expected of such volatility.

Betting Options and Payouts 

Bets span from €0.20 to €240, appealing to a broad range of budgets. The hit frequency of 1 in 3.74 ensures steady base-level activity, while the free spins trigger frequency (1 in 431) adds long-term excitement. 

The maximum win of 10,000x the bet positions Mermaid’s Treasure Trove as one of Pragmatic Play’s more generous cluster slots, though the probability of achieving it is 1 in 66,666,667, underscoring its rarity. 

Lower-tier clusters pay between 0.2x and 0.75x for five-of-a-kind, scaling up to 20x–150x for clusters of 15 or more. Combined with multipliers, however, these values can skyrocket, making even small base symbols lucrative in the right conditions.

Conclusion 

Mermaid’s Treasure Trove may not rewrite Pragmatic Play’s playbook, but it refines it beautifully. It’s a polished, high-volatility slot that merges the cascading energy of Fire Portals with an enchanting underwater setting. The multiplier wilds deliver a genuine sense of progression, while the free spins mode sustains intensity through sticky wilds and cascading merges. 

Visually serene yet mechanically fierce, it captures the duality of the ocean — calm on the surface, chaotic beneath. Though it occasionally feels familiar, its satisfying tumble flow, vivid presentation, and 10,000x potential make it a compelling addition to Pragmatic Play’s catalogue. 

For players who enjoy cluster mechanics, Mermaid’s Treasure Trove is a dive worth taking — one that glimmers with potential at every spin, rewarding those willing to explore its depths.
