How to play Mermaid’s Diamond

The slot has an unusual layout of 3-4-5-4-3, covered by 720 betways which pay left to right and right to left. Match three or more symbols from either the first or last reel to make a win. The game is set against a beautiful blue coral reef on the ocean floor, with anemones waving and fish swimming behind the delicate shell-adorned reel set.

Symbols on the reels start with various aquatic life: whelks, squid, starfish and plaice. Next come colourful gemstones: emeralds, sapphires, rubies and of course, diamonds. The pink-haired mermaid is the game’s wild symbol, and the treasure chest is a bonus scatter.

Trident Wilds

Any spin can produce this feature. Wild symbols are added at random to one or two of the reels, creating even more ways to win!

Free Spins

Land five of the treasure chest symbols to trigger the game’s main feature. Hitting four can result in the ‘Divine Intervention’ bonus, which nudges the reels to find the last chest. Pick one of the chests to reveal a number of free games - up to 25 per trigger. Additional spins can be won during the round: three, four or five scatters adds that amount of spins.

During the round, a diamond meter shows above the reels. Every diamond symbol that lands will light up a space on the meter. For every five diamonds, a reel is turned wild! When combined with the each way pays mechanics, this gives the chance to make some big wins!
