Slot machine details and review Mermaid’s Diamond
Mermaidβs Diamond is a fascinating online slot machine from the developer PlayΒ΄n GO, which focuses on an underwater world full of mysteries and treasures. This slot is popular for its high-quality graphics, innovative game mechanics and exciting bonus features. The game uses a unique reel format that allows for 720 ways to win. Combinations are counted from left to right. The reels are diamond-shaped with a 3-4-5-4-3 configuration.
Every slot machine must be developed by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific software provider, so they narrow down their selection by preferred brand.
The game takes you to a mysterious underwater world where sirens and sea creatures await you. The graphics are stunning β the background depicts the depths of the sea, while the reels are surrounded by pearl shells, corals and seaweed. The sound of the game perfectly complements the atmosphere thanks to the gentle sounds of waves and a magical musical background. Classic card values ββin the style of shells are among the low symbols. Precious stones are among the higher ones. The WILD symbol appears to complete winning combinations and thanks to it you can also enjoy a very interesting bonus game. In the case of Scatter symbols, their function remains the same β triggering Free Spins and one great bonus feature. During the free spins, you can collect more Scatter symbols, which will add more and more free spins to you.

The game features Scatter bonus symbols. If 5 Scatter symbols appear anywhere on the reels, the bonus spins will be activated within 1 regular game. When the Free Spins feature is activated, 5 chests will appear, from which the bettor will select 1 and the number of Free Spins awarded (10, 15 or 25) will be displayed. Your selection does not affect the payout percentage or the outcome of the game. During the Free Spins feature, all displayed Diamond symbols are added to the counter. If 5 Diamond symbols are collected, the Trident Wild Spins feature will be activated after the reels have stopped spinning for 1 bonus free spin.
In Bonus Spin mode, you can get additional bonus spins by landing Scatter symbols.

Our rating of the game
Mermaid’s Diamond
Mermaidβs Diamond is a perfect choice for players who like visually appealing games with deeper game mechanics. The bonus features are fun and often bring big rewards. The medium to high volatility is ideal for those who are willing to take risks to get bigger wins. This slot will not only entertain you, but also offer you a real chance to win interesting rewards. We can recommend the game not only to fans of underwater themes, but also to players looking for something more than just a classic slot.

Cons

Although bonuses are fun, they can take a long time to trigger
Big wins are more dependent on bonus rounds than regular gameplay
The underwater environment with mermaids may not be attractive to everyone
