Mermaid’s Diamond is a 5 reel, 720 ways to win slot from Play ‘N Go that can be played from 20p to £100 a spin on desktop, mobile and tablet devices (including iOS and Android). You go in search for treasure underwater with expanding wilds, free spins and divine intervention by sea god Poseidon in this Greek mythology themed offering where you can win up to 5,000 times your stake on each spin.

The first thing you’ll notice is that Mermaid’s Diamond is played in an elegant underwater setting on an unusual hexagonal reel set with 720 ways to win that offers pays in both directions – you can form wins by getting adjacent symbols from left to right and right to left starting on the outermost reels (reel 1 or 5).

Visually, you are taken to the depths of the sea – it has an epic feel to it with a serious and orchestral soundtrack. Symbols on the reels include 4 underwater creatures and 4 precious shin gems. The diamond is the most valuable giving you 10 times your stake for 5 across a payline.

You also have the beautiful mermaid who is the wild symbol – she substitutes for all other symbols bar the scatter. The wild is important as it can randomly trigger the Trident Wilds feature in the base game. Wilds are then added on 1 or 2 reels whilst the reels spin.

There is also a Divine Intervention feature which can be activated on a non-winning spin when 4 scatters appear on the reels – once triggered, the illusive 5th scatter symbol appears to trigger the Free Spins feature. The other ways of triggering the Free Spins feature is by getting 5 treasure chest scatters anywhere on the reels.

Once in, you have to choose 1 of the 5 treasure chests to reveal 10, 15 or 25 free spins. If you get 3, 4 or 5 scatters during a free spin, you will win 10, 15 or 25 more free spins – there’s no limit to how many free spins you can win! More importantly, look out for the sparkling diamond symbol.

When you collect 5 of them, you will trigger the Trident Wilds feature with 1 reel becoming filled with wild symbols. If you collect 4 diamonds and the Free Spins feature ends, these will be stored for the next time you enter the feature which is good. Anyway, you will get a wild reel for that free spin.

Mermaid’s Diamond is visually stunning, as are all Play ‘N Go slots, so there’s no surprise there – the variance is in the middle with maximum wins of 5,000 times your stake on each spin. Overall, a superb game from Play ‘N Go which is all about the wild reels in the Free Spins feature – get a few and you could receive god-like wins. If you like the theme, I highly recommend Novomatic’s Lord of the Ocean and IGT’s King of Atlantis which features Poseidon
