Mermaid's Diamonds Slot Review

The Mermaid’s Diamonds game can be found at casinos offering Play ‘n Go software. Play ‘n Go are a growing providers in the industry and have a rapidly expanding portfolio of both slots games and clients. They do offer a full casino platform, but primarily seem to be used as a bolt on package for extra slots games. Play ‘n Go do publish the Return to Player (RTP)/House Edge information for their slots games within the game help files. As such we know that the house edge for Mermaid’s Diamonds is 4%.

The Mermaid’s Diamonds game has 5 reels inside a slots frame that is shaped like a diamond. This means that the number of symbols per reel moving from left to right is as follows; 3,4,5,4 and 3. There are no traditional paylines, there are, however, 720 different winning combinations, moving from left to right and right to left.

The Wild symbol is a “Mermaid” and replaces all symbols except the red “Treasure Chest” Scatter symbols.

The Scatter symbol is a red “Treasure Chest”.

Bonus Features:

Trident Wilds – Any number of Wild “Mermaid” symbols will be added to one or two reels during a random spin.

Free Spins – If 5 red “Treasure Chests” appear on any spin the Free Spins feature is triggered. Once you have landed the 5 “Treasure Chest” Scatter symbols you are taken to a new screen where you need to choose one chest out of five where you can win 10, 15 or 25 free spins. If you reveal more of the “Treasure Chest” Scatter symbols during your free spins you will be awarded more free spins. 3 chests awards and additional 3 free spins, 4 chests awards an additional 4 free spins and 5 chests awards an additional 5 free spins.

During the free spins you can collect diamonds. When you reveal a diamond it is added to a space in the top right hand corner of the screen. There are five diamond spaces, when they are full, at least one reel will fill with the “Mermaid” Wild symbol.

Divine Intervention – If you reveal 4 “Treasure Chest” Wild symbols on a spin there is a random chance that the 5th reel will have a Scatter symbol added to it and unlock the Free Spins bonus.


Mermaid’s Diamonds is a visually appealing slots game. The diamond shaped frame makes the game look unique and the 720 different winning combinations makes the game feel like there is always something going on. The bonus features are a little more than your standard Free Spin, with plenty of random features to make the game feel less than predictable. The underwater theme is one we have seen before but Play ‘n Go have done a good job of adding enough shine and sparkle to elevate it above the usual fare. The predictable 4% House Edge means that you can most certainly shop around to find better value for money and to be honest, even just amongst Play ‘n Go games you will find offerings that throw up more entertainment and longevity than you’ll get in Mermaid’s Diamonds.
