Microgaming takes us beneath the surface to an underwater paradise of such splendour it would have David Attenborough eulogising. The graphics are nothing short of sumptuous. Coral, Sunken Treasure and Seaweed make up our high-paying symbols, while online slots developer favourites 10s through Aces bring up the rear as low-paying symbols. All symbols appear stacked on reel 1, including our top-paying Ariana – the beautiful mermaid of the game’s title. If a full stack of high symbols fills reel 1, all other matching high symbols become stacked on the other reels if it will complete winning lines. The game logo makes up our Wild symbol, substituting for all other symbols except Starfish Scatters.
Not only does our game logo Wild substitute for all symbols except Scatters in the base game, it can also appear stacked during Ariana’s Free Spins feature. Landing three, four or five Starfish Scatters triggers the bonus game, with 15 free spins on offer. Now, during the free spin, any stacked high symbol on reel 1 will expand all other high symbols and Wilds, ramping up the potential for big wins during the bonus game.
