Mermaid’s Diamond review
Play’n GO game developer has recently released an underwater-themed slot with an innovative hexagonal reel set, called Mermaid’s Diamond. Dive down in the company of an attractive mermaid to discover underwater treasures which result in big real money wins! If you’d like to learn more about this slot, keep reading our full review below, where we’ll be telling you what to expect from Mermaid’s Diamond slot as well as where to play it in order to get a good bonus.
Mermaid’s Diamond slot features
Mermaid’s Diamond is a 5-reel slot with 720 ways to win. Players can form wins by landing adjacent symbols both from left to right and from right to left. Symbols on the reels consist of 4 underwater creatures and 4 precious gems. The diamond is the most valuable symbol, and pays out 10x your stake for 5 in a line.
The reels also include a stunning mermaid symbol that functions as a wild and substitutes all other symbols except for the scatter. This wild can potentially trigger the slot’s Trident Wilds feature during the base game. During this feature, two wild symbols may be added to the reels for a chance of landing bigger wins!
Mermaid’s Diamonds slot Free Spins
Players will be pleased to learn that they may trigger a very rewarding free spins feature by playing this slot! You need to land on five treasure chest scatters anywhere on the reels, to be able to choose 1 of the 5 treasure chests to reveal your number of free spins. Players may initially get 10, 15 or 25 free spins. What’s more, if a player lands on 3, 4 or 5 scatters during a free spins round, he or she will win 10, 15 or 25 additional free spins, and the good news is that there’s no limit to the number of free spins you can win!
During this free spins round, you’ll also be looking out for sparkling diamond symbols that can emerge on the reels. If you manage to collect 5 of these, the Trident Wilds feature will be triggered once again. If you manage to collect 4 diamonds, these will also be stored for the next time you trigger this free spins feature.
If you land on 4 scatter symbols during the base game instead of 5 on a non-winning spin, you will get to experience the slot’s Divine Intervention feature, which leads to the appearance of another scatter, and a fifth chest that will still trigger the spins. Of course, we’ve nothing to complain about in this regard, since this is a very generous feature!

Mermaid’s Diamond  – our conclusion
We like Mermaid’s Diamond slot for its unique gameplay and bonuses, an in particular, we really love the fact that free spins can be triggered indefinitely. However, the game may require a little bit of patience if you’re after a big reward, as it’s not so easy to trigger the free spins feature. That said, payouts during the base game are not bad at all, and all in all, it’s worth playing Mermaid’s Diamond for real money if you’re looking for a high-quality slot with decent payouts. Try your luck today with one of our recommended online casinos, and don’t forget to look out for their best bonuses and offers!
