Being sung to by beautiful maidens while we are out at sea? Sounds heavenly. Until we learn that they are luring us to our doom! So goes the original tales of the ancient Greeks, whose Sirens were very much the kind to avoid. This is not so in Siren’s Kingdom Slot. A five reel, 30 payline Slot game with Free Spins, Expanding Wilds and Sticky Wilds. That promises safe passage across the seas without a word of doom but promises aplenty of watery riches. Developed by Iron Dog Studio and released through its affiliation with the NYX Gaming Group. The Siren’s Kingdom online slot has the capacity to captivate, enthrall and deliver wins of the most mythical potential.


While the original Sirens were renowned for luring sailors to their doom from rocks above the waves, Iron Dog Studio has opted to lead this five reel slots adventure beneath the surface. Rather than the bird-like creatures Homer told of in his Odyssey, Iron Dog’s Sirens take on the much more palatable form of mermaids. One such Siren floats by the side of our reels throughout, and while they don’t make up the game’s high-paying symbols we can look forward to seeing them as Expanding Wilds that pay as the game’s top-paying symbol on any line during the base game and Sticky Wilds during the Free Spins bonus feature.

Our high-paying game symbols, meanwhile, are made up of other jewels of the sea. Various Shells take the mantle as our high-payers, while a Starfish, Ace and King come in as medium-paying symbols and the low-payers reserved for the much more standard 10, Jack and Queen. Any and all symbols can appear stacked to help boost our wins during the base game, and all artwork is sumptuous and accompanied by a mystical watery soundtrack that could come from the mouths of the Sirens themselves.


The Siren Wilds appear on the top row of any reel and expand to cover that reel, substituting for all symbols except Octopus Scatters to complete winning combos. Landing three, four or five Scatters anywhere across the reels triggers the Free Spins bonus game, awarding 14, 25 or 36 free spins respectively. The more the merrier, of course, though we do have the added help of the Siren Queen throughout all free spins variants. She is now a Sticky Wild, appearing in any position on any given reel.

But our Siren Queen is also an Expanding Wild, for every time she lands she will be held for a spin before expanding outwards to cover two additional positions on reels either side for a single spin. Should we land more Siren Queen Wilds in those concurrent spins we will be looking at multiple line wins. With our Wild wins paying out as top-paying symbols, the Siren’s Kingdom free spins game is one feature that is sure to lure us in to the mystical deep.


The enchanting deep is a favourite setting for slots studios, with Microgaming’s classic Mermaids Millions slot whetting our whistles for mermaid-themed slots and releases like NetEnt’s Secrets of Atlantis bringing modern twists to classic themes. Iron Dog Studios follows suit with its Siren’s Kingdom slot, with neat enough graphics and gameplay but a Free Spins feature and tasty base game and bonus Wilds providing plenty to get us into deep water in which we will relish being submerged.
