Barcrest, a company that was bought by Scientific Games in 2011, did a fantastic job with this slot’s graphics and special features. Whether you play this game for free or for real money, get ready to embark on an epic voyage. 

Mermaid Queen Slot Symbols and Values

Mermaid Queen slot machine is a 5-reel and 3 row slot that has 10 different paylines to win. After hearing fantastic stories about this half-woman, half fish (1), you’re bound to be excited to finally be able to meet her or, at least, encounter her. 

Barcrest realised this excitement which is why the slot begins straight on a vessel to start your journey in the deep wild sea, sailing towards the sunset. However, the game also takes you into a completely different setting if you’re lucky enough to trigger the free spins. You’ll be taken deep underwater which is the mermaids’ domain. This provides a sudden change of scenery which most players love. 

A total of 13 symbols can appear on the mahogany-filled reels and while Barcrest has done a great done at this slot’s graphics, its audio reflects that of the typical slot machine. Symbols range from mermaids, sailors, dolphins, ships, a golden treasure, binoculars and secret treasure maps and a clam with a mystical round ball inside it. 

The highest paying symbol in this slot game is the mermaid who pays 500x your bet when matching 5 or more symbols on the reels. The sailor also pays the same prize when matching 5 or more symbols on the reels. The lowest paying symbols are the typical card poker symbols, the lowest paying 10x your bet when matching 5 or more symbols. 

If you’re interested in getting to know more about different payouts for each symbol, you can check out our paytable below.

Mermaid Queen Free Spins Bonus

Mermaid Queen slot’s free spins are undoubtedly the game’s most attractive and enticing feature. These spins change the game’s dynamic and even take place in a different setting with a different mechanic. The reels behave differently to the main game here and symbols are uncovered rather than falling into place. This adds another element of mystery and spice to the game. 

Starting off with the triggering free spins. Three scatter symbols, represented by the mermaid symbol, trigger an exceptional 15 free spins. Scatter symbols don’t have to fall across a payline but you can land them anywhere on the reels to trigger the free spins. 

As mentioned before, when triggering the free spins, the reels change. While the grid remains the same size, the symbols are uncovered from behind a blue curtain rather than falling into place like in the main game.

Free Spins Multiplier

While you might think that 15 free spins are reward enough, wait till you find out about the free spins multiplier. All wins are multiplied x3, making the Mermaid Queen free spins all the more enticing if you’re lucky enough to win big! 

In this game, the wild symbol doubles all pays it substitutes for.

Mermaid Queen has an RTP of 94.06% and it has a high volatility with a staggering maximum win of 250,000x your bet. Although this gigantic win is not that frequent, the prize is bound to attract high rollers (2) to the game. 

The slot game has a minimum bet of 1.00 and a maximum bet of 250. It is extremely easy to adjust the size of your bet by using the bet level buttons. The maximum possible win when lading 5 or more symbols on the reels is 500x your wager.
