Review of Mermaid's Diamond

Dive into the magical world of Mermaid’s Diamond, where you are guaranteed to find a whole lot of treasures at the bottom of the ocean. Diving for gold if you like. Play ‘ N Go have managed to create a game with all of the elements that we have ever wished for in an underwater themed casino game, along with the calming ocean music and graphics to match.

Upon first entering the Mermaid’s Diamond slot game you are greeted with the relaxing sounds of the ocean and some very beautiful symbols consisting of fish, shells, jewels, starfish and even squid. The colourful symbols create something a little bit extra enticing in the slot, and it automatically puts you in a good mood.

The minimum bet that you can place in this slot game is £0.20, and the maximum bet that you can place is £100, so choose wisely and be sure to keep in mind that you can adjust your bet at any point in the game except for when you are in a special feature.

Trident Wilds

This is a fantastic feature that Play’ N Go implemented into Mermaid’s Diamond, it’s a random feature meaning it will be triggered randomly during the base game. When it’s triggered, Wild symbols are added on between one and two reels whilst the reels are still spinning, however this feature doesn’t guarantee any sort of winning combination. The Wild symbols in this game are the beautiful mermaid herself so you definitely won’t miss it!

Divine Intervention

The Divine Intervention feature in Mermaid’s Diamond can be triggered during non-winning spins which show four Scatter symbols anywhere on the reels. If it is triggered the fifth Scatter symbol which is needed in order to activate the Free Spin feature will appear on the reel.

Free Spins

The Mermaid’s Diamond Free Spin feature can be triggered when 5 Scatter symbols have landed on the reels. When this exciting feature happens, 5 treasure chests will appear on the screen, you must pick one of them and reveal a number indicating how many Free Spins you have won! The Free Spins can be either 10, 15 or 25.

During Free Spins, some beautiful Sparkling Diamond symbols can appear, if you collect 5 diamonds it will trigger the Trident Wild feature. When the required number of diamonds is reached, Wild symbols will be added to the reels and help you to make winning combinations. There is one last thing, the Mermaid’s Diamond Free Spin feature can be extended when the Scatter symbols end up landing on the reels. If you manage to land 3, 4 or 5 Scatter symbols on the reels, it will award you with another 3-5 Free Spins. This extra feature can be triggered an unlimited number of times.

if you collect 5 diamonds it will trigger the Trident Wild feature
