Mermaids Diamond

Mermaid’s Diamond Slots


Mermaids have been a fascinating topic of discussion for many years. While some believe that mermaids are a myth, others swore that they have seen them while on the sea. Also, there are people who say that mermaids are devilish creatures which are carnivores and others agree that they are merely human-lovers, who are just too afraid to come on land. Until these debates are agreed on, you can discover the mermaid’s world at Rialto Casino by playing Mermaid’s Diamond Slot. Designed by Play’n Go, this game is a 720 ways to win one. The game opens on a backdrop displaying the underwaters, where you will see bubbles of water and sea creatures racing.

Take a dip into the waters by placing your stake. On the display of Mermaid’s Diamond Slot, you will see different bet tabs ranging from a minimum of £0.20 and climbs up to a maximum of £100.00. You just need to press on your preferred stake to activate it.

On the same display, you will also see the Auto-Play Tab. This lets you select 10 to 50 games to be played on auto-mode; the game plays simultaneously, without you having to intervene at any point. You can as well add a win or loss balance so that the game is stopped at once.


The watery symbols you will see on Mermaid’s Diamond Slot are Beautiful Mermaid, Diamond, Red Gem, Blue Gem, Green Gem, Stingray, Starfish, Squid and Shell. The top paying symbol is the Diamond which pays 1000 coins when 5 such symbols are seen in any position on the reels.

There is a unique Trident Winds Round on Mermaid’s Diamond Slot. At random, a mystical force adds wild symbols on the reels to create more winning possibilities.

Another feature is the Divine Intervention Round. During a non-winning spin, which consists of 4 Scatters, the last Scatter is added to the reels.

When 5 Scattered Treasure Chest symbols are seen on the reels, you trigger the Free Spins Feature, awarding up to 25 free spins. You will be required to select one out of 5 Treasure Box to determine how many free spins you have won. During the feature, landing either 3, 4 or 5 Scatters on the reels, extends the feature and respectively awards 3, 4 or 5 additional free spins. Each time a Diamond symbol appears on the reels during the free spins, these will be collected. Once five of these have been collected, one reel will be full of wild symbols!
