Scientific Gaming has provided their fans with a new slot release called Mermaid Queen which is playable across all devices and offers quite the theme combo. The background of the reel reminds us of the Black Pearl, Jack Sparrow’s boat, but the mermaids really give it a different spin. It is like the rough and the gentle are combined together in this slot, presented with clear graphics and vivid colours.


The Pirate symbol is the Wild in Mermaid Queen. It will substitute any symbol except for the Mermaid symbol, which is the Scatter in the game. As soon as the Wild forms a winning combo substituting for a symbol, it doubles the win it substitutes for. Other than that, you should know that 5 Wild symbols across a full payline will give you 500x the stake win.

5 Mermaid Scatter symbols will give you a 500x the stake win, just like 5 Wilds.3 or more Mermaids will trigger 15 Free Spins, and during those games, the wins are multiplied by 3.

During the Free Spins, since all wins are multiplied by 3, it means that the maximum win potential in Mermaid Queen is 1,500x the stake, which for the highest stake means a lot!

Theme & Design

The background, as we mentioned, looks like the ship from the Pirates of the Caribbean film series. The Pirate/captain/sailor symbol is accompanied by the beautiful Mermaid Queen on the reels, along with the pearls, the treasure chest filled with gold, dolphins, ship pictures, and a paper letter with an antique monocular and some coins on top. Other than that, you can see the playing card symbols from A to 9, which represent the lowest paying symbols.

During the Free Spins, you will see another background and reels. In the background, you will see the bottom of the big blue sea, with some bubbles on top of the reels. The symbols are covered with blue mermaid pictures, and as you play, they uncover and transform into the regular symbols.

Wagering & Paylines

There are 10 active paylines in Mermaid Queen, where the betting starts from $0.10, meaning $0.01 per line. The maximum you could bet is $500.00, which means $50.00 per line.

The payouts in this slot are quite outstanding, actually, although the RTP is really lower than expected from SG, just 94.00%. Nevertheless, the $750,000.00 you could get for the maximum win potential during the Free Spins when the 3x multiplier is active should make up for that disappointing RTP.


Although the game may seem simple at the first glance, there is actually so much to it than meets the eye. The Pirate Wild doubles prizes in winning combos and substitutes symbols, the Mermaid Scatter adds multipliers, rewards you with Free Spins, and leads you to a max potential of 1,500x the stake. That's a lot to win here, a lot of actions to trigger and such beautiful underwater views presented with the cutting-edge graphics. SG has done a great job with Mermaid Queen, although they could have given a slightly higher RTP in order to boost our motivation to play it.
