Inspired by an underwater adventure, Play N’ Go’s Mermaid’s Diamond slot game is an eye-catching experience for players of all levels. The game is backed with some of the very best graphics on offer and the background is also highly interactive with animations that continue to follow the underwater theme that has been produced.

When creating this Mermaid’s Diamond review, we have taken a look at all the important details players will need to know about the slot game, whilst also providing the reader with all the necessary information about how to play this highly exciting title.


Mermaid’s Diamonds is a simple game to play and has a number of things within the slot game to keep players interested for as long as possible. Based on a five-reel grid that consists of a 3x4x5x4x3 formation, there are an impressive 720 different paylines available to win from with each symbol offering a different payout value. Furthermore, bet ranges will appeal to players of all budgets as they can be placed as low as 0.20¢ and be as high as €100 per spin. There are a number of Mermaid’s Diamonds Free Play demos available for players who want to test the game before playing for real money, which is incredibly handy.

As with any slot game, adjusting the settings before the first spin could be a wise move and one that is rather easy to complete. There are ‘+/-’ buttons situated next to the ‘Coin Size’ button, which allows players to set a range from between 0.2 and 100. There are not many other options to change, though, with players having the standard ‘Autoplay’ and ‘Play’ buttons available.

Whilst doing our Mermaid’s Diamonds review, we found that there is a mobile version of the slot game available to play, although that is hardly surprising as Play N’ Go have managed to make that cross-compatibility a staple of their game offering as they continue to remain an industry leader amongst developers who produce slot games.

Feature Bonuses

Mermaid’s Diamonds feature bonuses are available in abundance in this Play N’ Go title, which certainly helps to keep this game at the upper levels of interest from players.

The Wilds and the Scatter symbols are crucial to these bonus features, as both will provide players with different but equally satisfying things.

The ‘Trident Bonus’ is one of the random bonuses to feature in the slot game, with it happening on random spins. The bonus will add one or two wilds to the reels to help boost the possibility of winning big.

If four scatters are landed upon the reels but a win is still not possible – just our luck – then fortunately the ‘Divine Intervention’ bonus feature will come to the rescue. This feature will add a fifth scatter to the reels, which in turn will trigger the ‘Free Spins’ round; happy days!

Once activated, the ‘Free Spins’ round will bring up five treasure chests, in which the player will choose from. Once one has been selected, it will show how many free spins have been won, with 25 being the maximum. If three or more scatters are landed on in this round, then more free spins can be won.

Diamond symbols will be collected during this Mermaid’s Diamonds feature bonus round, and when five are collected, a wild reel will be added to the game to help bring even more wins to the player’s balance.

RTP (return to player)

A return to player rate (RTP) of 96.5% and a medium volatility level makes Mermaid’s Diamonds an appealing game for players to spin to, as the possibilities of winning are favourable.
