Mermaid’s Treasure Trove is a deep-sea cluster pokie that turns small wins into bigger moments through multipliers that stick around and level up. You’re hunting 5+ clusters on a 7×7 grid, then letting tumbles keep the spin alive. When the wild multiplier shows up, it can start snowballing properly quickly.

Game Overview
Mermaid’s Treasure Trove plays on a 7×7 Cluster Pays grid. You need clusters of 5–15+ matching symbols, and the base game can reach up to 150x. After each win, symbols tumble away and new ones fall in for fresh chances. The key mechanic is the Wild Multiplier: if your winning cluster doesn’t already contain one, a wild multiplier appears afterwards, starting at 1x and increasing by +1x each time it features in another winning tumble. If more than one lands in the same win, their values are added together. Regular symbols can also land with random multipliers up to 100x. Trigger the bonus with 3–7 scatters for 10–18 free spins, and every extra scatter during the feature adds one more spin. In free spins, wild multipliers stay sticky until the round ends.
Game Features & Mechanics
-
Wild Multiplier Drop
After any win that doesn’t include a wild, the game drops in a Wild Multiplier. It starts at 1x and can build from there.
-
Roaming Wild Growth
If a Wild Multiplier helps create the next tumble win, it steps to an adjacent square and increases by +1x. Multiple wilds can merge, combining values.
-
Random Symbol Boosts
Regular symbols can arrive carrying their own multipliers, from 5x up to 100x. When they’re inside a winning cluster, that value boosts the payout.
-
Sticky Free Spins
Trigger free spins with 3–7 scatters for 10–18 spins. In the feature, Wild Multipliers stay sticky on the grid, and extra scatters add +1 spin.
Technical Specifications
-
Volatility Level
This one is built for swings: high volatility means the base game can go quiet, then a single tumble chain with growing wilds can spike hard.
-
RTP Explained
Mermaid’s Treasure Trove is commonly listed at 96.54% RTP. That’s a theoretical long-run return, and operator settings can vary, so it’s worth checking your in-game info panel.
-
Bet Range
Most casinos set stakes from $0.20 up to $240 per spin. It’s friendly for testing low, but also gives room to push higher if you want.
Paytable & Symbol Values
Mermaid’s Treasure Trove keeps the base symbols thematic and easy to read. Your low pays are a blue seashell, green starfish, and gold fish - these are the clusters you’ll see most often, and they’re mainly there to keep tumbles alive. The higher-value icons are the horn, harp, treasure chest, and crown, and these are the ones you want landing in bigger clusters when multipliers show up. Wins pay via clusters of 5+ connected symbols, scaling up through 15+. As a rough spread, small 5-symbol clusters sit around 0.2x–0.75x, while the best 15+ clusters climb as high as 150x.
Special Symbols
Mermaid Scatter
The Mermaid is the Scatter and the bonus trigger. Land 3–7 scatters to start 10–18 Free Spins, and any extra Scatter during the feature adds one more spin.
Bubble Wild Multiplier
The blue bubble acts as the Multiplier Wild. If a win happens without a wild, one appears afterwards, starting at 1x, then moves and grows by +1x whenever it helps form another win.
Random Symbol Multipliers
Regular paying symbols can also land carrying their own multiplier, up to 100x. If that symbol is part of a winning cluster, its multiplier boosts the payout and can combine with multiplier wild values.
Graphics, Animations & Sound Design
-
Graphics
Mermaid’s Treasure Trove goes full underwater fantasy: glowing reefs, soft blues and greens, and treasure icons that pop against the darker seabed backdrop. The 7×7 grid can look busy at first, but the symbol shapes are distinct, so clusters are easy to spot once tumbles kick in.
-
Animations
The tumbles are quick and clean - wins dissolve, the grid refills, and the next cluster is already forming before you’ve blinked. When a Wild Multiplier appears after a win, it’s clearly marked, and you can see it step to a neighbouring spot and level up as it keeps contributing.
-
Sound Design
Audio is chill rather than aggressive: airy chimes, watery swells, and a brighter sting when multipliers land or merge. It does a good job of signalling about what’s coming - quiet when spins are dead, then a more energetic lift when the tumble chain keeps extending and the wild starts growing.
-
Visual Feel & Interactivity
This slot’s “feel” comes from watching the board evolve. You’re not staring at lines - you’re tracking where clusters are forming and whether the wild is about to become the centre of the next hit. In free spins, sticky wilds keep that sense of build-up across spins instead of resetting.
Game Gallery
Mermaid’s Treasure Trove on Mobile Devices and Other Platforms
Mermaid’s Treasure Trove is a good mobile fit because the “read” is simple: find clusters, follow tumbles, and watch the multiplier wild once it drops in. The only real challenge on a phone is visibility - when the grid is refilling quickly, you want enough screen space to see where the wild moved and whether it merged with another multiplier. In free spins, stickiness makes that even more important, because your best outcomes come from seeing (and understanding) how the board is building over time.
-
Android
Android plays smoothly in-browser, and the 7×7 grid stays clear on modern screens. Landscape helps you track where the wild shifted and whether it’s about to merge.
-
iOS
On iPhones, tumbles feel snappy, which suits the slot’s rhythm. Keep an eye on the wild’s position after each win - it’s easy to miss a move on smaller screens.
-
Tablet
Tablets are the comfort pick. You get a larger view of the grid, so it’s easier to follow cluster shapes, see multiplier values, and notice when two wilds combine.
-
Desktop
The best one for long sessions and rules checks. It’s the easiest place to follow fast tumble sequences and confirm the exact feature options your casino offers.
Optimal Gameplay Tips
-
Use Stable Connection
EssentialTumbles can chain quickly, and a drop-out mid-sequence is painful. A stable connection keeps animations and symbol updates clean, so you can follow wild movement properly.
-
Landscape Mode Recommended
RecommendedLandscape gives the grid breathing room. You’ll see clusters form more clearly, and it’s easier to track where the wild moved, especially during longer tumble streaks.
-
Audio Settings
OptionalYou can either turn the sound off or keep it low/full volume. Keeping it is better since audio cues help flag multiplier drops and merges, which is handy.
-
Full Screen Mode
RecommendedFull screen reduces distractions and makes the grid easier to read. When free spins are running and wilds are sticky, that clarity helps you follow the build-up.

- Cluster Pays on a 7×7 grid keeps every part of the board relevant
- Sticky multipliers in free spins give the bonus a real build-up across spins
- Random symbol multipliers can spice up the base game without needing a feature
- The theme is clean and readable, even when tumbles start flying
Things to Consider

- Operator settings can vary, so confirm RTP and limits in your in-game info
Overall Rating
7.8
Bottom Line
Mermaid’s Treasure Trove is a cluster slot for players who like watching a mechanic grow rather than relying on one-off luck. You’ll hit clusters, watch tumbles extend a spin, and wait for the Wild Multiplier to drop in and start levelling up as it keeps contributing. Free spins are the main event because sticky wilds give the grid time to develop, and that’s where the slot’s best “story spins” come from. If you’re happy with a swingy ride and you want a clear chase mechanic you can follow, it’s a strong pick.

Frequently Asked Questions
How do you trigger Free Spins in Mermaid’s Treasure Trove?
Land 3–7 Scatter symbols to trigger 10–18 Free Spins. During the feature, any extra Scatter adds one additional spin, keeping the bonus alive a little longer.
What does the Wild Multiplier do?
After a win that doesn’t include a wild, the game drops a Wild Multiplier onto the grid. When it helps create another win, it moves and increases by +1x.
Can regular symbols have multipliers too?
Yes. Paying symbols can land carrying random multipliers (up to 100x). If that symbol is part of a winning cluster, its multiplier boosts the payout.
Are the Wild Multipliers sticky in the base game?
No. Stickiness is a free spins perk. In the base game, wild multipliers can appear and grow during a tumble chain, but they don’t stay locked on the grid between spins.
