Theme
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.
Bonus Features
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.
