Introduction
This nautical themed game from Barcrest slots takes place across five reels. Each reel shows three symbols, and as you might expect these all have a seafaring aesthetic. A beautiful mermaid pays the most, followed by a sailor, a dolphin and a ship.
Medium-value symbols consist of a treasure chest, a pearl and a telescope. The letters A and K complete the set. Mermaid scatters award free spins, and the wild can substitute for any symbol apart from the scatters, providing more potential for wins.
There are 10 paylines. The free spins round is undoubtedly this slot’s biggest draw, not least because spins are so easy to trigger. Landing just three scatters awards 15 spins, and these come with a multiplier.
Theme & Design
Mermaid Queen takes place in two different settings. The main game occurs on the deck of a ship, complete with rigging and a distant sunset. If you’re lucky enough to trigger free spins, you’re conveyed to the underwater domain of the mermaids, where the action takes place on a different set of reels.
We loved the sudden change of scene, which makes the free spins feel particularly special. The alternative reels behave differently to the main game, as symbols are uncovered rather than falling into place. This adds some welcome variety, and since those symbols (especially the mermaid herself) are so well designed, the slot is always a joy to look at.
Symbols animate after a win, which is a nice touch, and the slot is full of little features that show commendable attention to detail. That said, we would have liked some background music. A mystical sound effect plays as the reel spin, but it’s no substitution for a musical score.

Mermaid Queen RTP & Volatility
Mermaid Queen has an RTP of 94.06%. It’s a high-volatility slot with a staggering maximum win of x250,000. Don’t forget that gigantic wins are uncommon on any slot and should never be counted on.
How to Play Mermaid Queen
With its different reels and bonus features, Mermaid Queen might seem slightly confusing to begin with. We’ve put together this quick guide to help you get started.
1. When the game loads, press the giant question mark button and then use the on screen arrow keys to cycle through the game rules, paytable and bonus information.
2. Press the home button to return to the main game.
3. You can control sound levels by using the cog icon, which is at the bottom left of the screen.
4. Adjust your wager using the - and + buttons on either side of the bet box.
5. If you would like to use autoplay, it’s located to the side of the spin button. You can set the number of autospins up to a maximum of 100 with loss/win limits.
6. Now you just have to press play, but always remember to enjoy Mermaid Queen responsibly!
Bet & Win Sizes
Mermaid Queen has a minimum bet of 1.00 and a maximum of 250. It’s easy to adjust the size of your wager using the bet level buttons. The maximum win possible for x5 matching symbols across a payline is x500.
Here are the payouts for five matching symbols.
Five mermaids = x500
Five sailors = x500
Five dolphins = x75
Five ships = x75
Five treasure chests = x40
Five pearls = x25
Five telescopes = x25
Five As = x12.50
Five Ks = x12.50
There are 10 paylines in play, and the highest possible win is x250,000. Massive wins like that are (unfortunately) incredibly rare.
Mermaid Queen Free Spins
Mermaid Queen’s free spins round is undoubtedly its most attractive and potentially lucrative feature. These spins completely change the dynamic of the game and even take place across a different set of reels with a different mechanic.
Let’s take a closer look at how this feature works, and how to trigger it.
Triggering Free Spins
Landing just three scatter symbols awards a very respectable 15 free spins. Better still, scatter symbols don’t have to fall across a payline. Landing them anywhere on the reels is enough to trigger the spins.
Free Spins Reels
When you trigger the free spins, you’ll notice that the reels change. The grid remains the same size, but symbols are revealed from behind a blue curtain rather than falling into place.
Free Spins Multiplier
While 15 free spins might seem generous enough, the free spins round also comes with a multiplier. All wins are multiplied x3, making Mermaid Queen free spins some of the most lucrative around if your luck holds!
Concluding Thoughts
Mermaid Queen is very much a back-to-basics offering from Barcrest, who do a fantastic job at delivering a gimmick-free smooth main game while still including a massive twist with the free spins round.
In a world of online slots increasingly dominated by flashy graphics and overcomplicated features, we loved the simplicity of Mermaid Queen, especially as it’s so attractive to look at and runs so smoothly. The free spins bonus game is undoubtedly the biggest draw, not least because it offers so many spins for just three scatters but also because it changes the entire dynamic of the slot.
Free spins on Mermaid Queen feel exciting, thrilling and unique, and this builds tension throughout the main game too. As scatters appear, the tension ramps up as you start hoping for the bonus game!
