Our Review of Mermaids

Mermaids Slot Review by NetEnt

Mermaids from NetEnt is that ocean slot that looks cute but lowkey wants to delete your balance then hand you a 2000x and act innocent. Progress bars, Random Wilds, stacked mermaids this one hits different.

Core Gameplay Vibes

Standard 5x3 grid with 20 paylines. Super clean layout. No brain melt needed. You just spin, watch the mermaids cook, and keep an eye on those three Globes sitting above the reels.

Every time a Progress Wild lands, it charges its matching Globe. You have:

  • Purple Progress Wilds feeding the Purple Globe
  • Green Progress Wilds feeding the Green Globe
  • White Progress Wilds feeding the White Globe
  • Plus a Regular Wild that only shows up during Random Wilds moments and pays like a boss

Base game is very much a slow burn grinder. You are farming Globes, not praying for random Scatters. It feels like a mobile gacha bar slowly filling up, and that is mad satisfying when it pops.

Wilds and Progress Globes

This is the whole identity of the slot. Forget Scatters. The Wilds are the shot callers here.

  • All Wilds sub for any pay symbol and can give you the top line hit when you land 5 of them.
  • Each Progress Wild pumps charge into its Globe above the reels.
  • When a Globe fills you trigger its special hype mode.

The sick part is your Globes do not reset between spins in the base game. You are effectively on a long mission. Every session you are like “just one more purple just one more green” and suddenly you are in full bonus spam.

Picker Bonus Purple Globe

This is your first real dopamine hit and the one you will see the most.

  • You start with 5 Purple Globes already filled.
  • Reach 15 Purple Globes total and you trigger the Picker Bonus.
  • You get 3 picks from hidden treasures.

Behind those picks you can grab:

  • Multipliers like 2x 3x 5x 10x 12x 15x 20x 25x or a spicy 50x
  • Mermaid Spins triggers
  • Wild Spins triggers

What is clutch is that if you reveal Mermaid Spins or Wild Spins here, you get that feature without resetting their own Green or White Globes. So the Picker can basically fast track you into the bigger modes while your long term progress stays intact. That is huge value.

In practice this bonus is a mixed bag. Sometimes it is mid with low multis. Sometimes you pick a 50x and suddenly the base grind feels worth it. It is a nice little bankroll top up while you chase the real ocean madness.

Wild Spins Green Globe

Now we are talking. This is where the screen starts looking cooked in the best way.

  • You start with 5 Green Globes.
  • Hit 30 Green Globes to trigger 10 Wild Spins.
  • Every spin has Random Wilds landing on the grid.
  • Green Progress Wilds do not appear during these spins so you are here to print not to farm.

Random Wilds are the whole show. They can splash across the reels and suddenly your board is full of stacked mermaids and Wilds connecting everywhere. It is not always insane but when the Random Wilds land in a line or cluster it feels so clean.

Wild Spins are the mid tier hype mode. They will not always send you to the moon but they are way more explosive than the base game and can chain some really solid wins if the RNG is on your side.

Mermaid Spins White Globe

This is the premium ocean content. The mode you lowkey chase from spin one.

  • You start with 5 White Globes.
  • Hit 60 White Globes to trigger 10 Mermaid Spins.
  • Random Wilds are active here too.
  • No royals at all. All low card symbols are yeeted from the reels.
  • White Progress Wilds stop appearing during the feature.

That last detail is key. No low symbols means your Random Wilds are connecting into mermaids and premiums way more often. The board just looks expensive. Every spin feels like it could be the one.

Mermaid Spins is where your max win dreams live. Random Wilds plus only premium symbols is such a cracked combo. When the Wilds drop in the right spots and you see full lines of golden or red mermaids, that is main character energy no cap.

Symbol Payouts and How You Actually Print

The paytable is simple but it supports the whole high volatility vibe.

  • Lows: 10 J Q K A. Five of a kind is small money.
  • Highs: Four different mermaids turquoise purple red and golden.
  • The top mermaids and Wilds can pay up to around 100x for a full line.

So the game is not about one symbol being insane by itself. It is about stacking multiple strong lines during Wild Spins or Mermaid Spins. You want Random Wilds to chain across reels and connect multiple mermaids at once. That is how you climb toward those 4 digit multipliers.

Who Is Mermaids For

If you love watching meters fill and features stack, this is your lane. It feels like a casual underwater slot on the surface but the math is not soft. It is high volatility and the dead spins can be brutal if your Wilds are hiding.

But if you are the type to sit back farm progress and wait for that one cracked bonus session, Mermaids is a vibe. It is also super friendly for newer players since the UI is clean and the features are easy to understand. No megaways math no cluster brain fog just Wilds and Globes doing their thing.

Max Win Potential

The max win is just over 2000x which in today’s market is decent but not insane. This is not a 10 000x degen machine. It is more of a consistent high volatility grinder where a 200x to 600x Mermaid Spins round already feels like a huge W.

If you are chasing only giga max wins this might feel a bit tame. But if you like a more realistic shot at a solid multi without needing a miracle this is actually pretty clutch.

✓ Pros

  • Progress Globes make every spin feel like you are building toward something
  • Mermaid Spins with no royals and Random Wilds is straight up fire
  • Art and animations are super clean classic NetEnt polish
  • Picker Bonus can high roll with big multipliers or extra features for crazy chains

✗ Cons

  • Max win just over 2000x might feel a bit low for hardcore max win hunters
  • High volatility means base game can feel dry while you farm Globes
  • No classic Scatter trigger some players might miss that simple bonus chase

Bottom Line

Mermaids is that sneaky ocean slot that looks soft but absolutely has teeth. The Progress Wild and Globe system is addicting you always feel one step away from something big. Picker Bonus keeps the pace up Wild Spins bring the first real chaos and Mermaid Spins is where you can genuinely cook a massive session saving win.

If you want a chill looking game with real high volatility energy and you are cool with a 2000x ceiling this is a strong pick. If you only want giga max wins and instant nonstop bonuses you might call it mid and move on.

For most of the community though this is an easy recommend. Fire visuals satisfying progress mechanics and enough clutch factor to keep you saying one more spin way too many times.
