Mermaid's Diamond Slot Review & Casinos

Mermaid's Diamond from Play'n GO is an underwater slot that takes you deep into the ocean where you can meet the seductive mermaid who helps you find some ocean treasure. The theme may not be the most creative out there, as there are many other games with a similar theme, but the game has some interesting game mechanics and the graphics are created with a lot of attention to detail. The symbols include colourful gems, sea creatures and the beautiful mermaid. The music and sounds also support the game nicely and create a somewhat eerie atmosphere. You can win with 720 way-wins and free spins with the chance to get extra wilds. Winning combinations are possible from right to left and left to right, and you need at least three symbols on adjacent reels to win. The top prize is 5000x your bet!

The volatility of the game is a low to medium, and you will probably get regular winning combinations with smaller, and the occasional larger win. The free spins can really make the game worthwhile, so it's best to play it until you get to the free bonus spins. The theoretical return to player is 96.5%, which is average for a casino slot. You can also play Mermaid's Diamonds mobile on many different devices, as the game was developed in HTML5 and is compatible with many different platforms.

Wilds and up to 25 free spins with possible wild reels

The mermaid is the wild symbol in the game, and she replaces other symbols for winning combinations. There are also the Trident Wilds that can randomly appear during the games.

The symbol with the treasure chest is the scatter symbol that starts the free spins. You need at least 5 scatter symbols to start free spins, but if you only have 4 the Divine Intervention feature may magically place the fifth treasure chest on the reels. Before the free spins start you have to select one of the chests that can reveal up to 25 free spins.

The free spins can also be extended if you get additional scatter symbols during the free spins. There is no maximum amount of free spins that you can get, they can be re-triggered indefinitely. However, What makes the free spins really special are the diamonds. Each time you get a diamond on the screen you will collect it and once you have 5 diamonds a minimum of one complete reel will be filled with wild symbols leading to potentially huge winnings. You can win a maximum of 5000x your total bet in the free spins.
