Mermaid’ Diamond takes players under the sea to a world of treasures. The transparent reels are set on the seabed, complete with fish swimming past and bubbles rising from the bottom. The theme is further brought to life with the aid of atmospheric music and sound effects.
All of the slot’s symbols are thematic. They include a diamond, red, blue and green gems, a flatfish, a starfish, a squid and a shell. The mermaid is the wild symbol and she will substitute for all of the other symbols, except for the scatter symbol, to help and form winning combinations. The scatter symbol is the treasure chest.
The wild symbol comes with a bonus feature called trident wilds. When the wild lands, it may trigger the feature and add additional wilds to one or two reels while the reels spin.
There is a bonus feature called Divine Intervention. If you land four scatter symbols on a non-winning spin, then it may add a fifth scatter symbol to the reels, which will then trigger the free spins. The free spins can also be triggered by landing five scatters directly on the reels.
Once the free spins have been triggered, you need to choose one of the five treasure chests to reveal how many free spins you have won, 10, 15 or 25. During the free spins, landing three, four or five scatters will award an additional 10, 15 or 25 free spins, and there is no upper limit to how many can be won. During the free spins, any diamond symbols that land are collected and when you have five of them, at least one of the reels becomes completely wild for the rest of the spins. If you collect four diamonds and the free spins end, then the diamonds are stored for the next time that the free spins are triggered.
Mermaid’s Diamonds is a medium volatility slot and it has an RTP of 96.00%, which is exactly the average for online slots. As it is a medium volatility game, you can expect to hit reasonable sized wins every few spins. However, there are no guarantees.
All payouts are multiples of the total bet. The diamond offers the top payout of 10x when five land across the reels. The red gem can payout up to 2.5x, the blue gem up to 1.5x, and the green gem up to 1x. The flatfish and starfish can both payout up to 0.75x, while the squid and the shell can both payout up to 0.5x. Theoretically, it is possible to win up to 5000 times the bet on a single spin.
How to Play
Mermaid’s Diamonds is a very easy game to play. Before spinning the reels, players need to set their total bet per spin using the controls underneath the reels, and it can be anything from 0.20 up to 100. When players are happy with the bet they just need to click on the spin button to start the reels. There is also auto play functionality that can be used to set up to 100 spins in motion complete with stop conditions.
