Siren's Kingdom Slots

Siren’s Kingdom video slot, is one of the latest releases from software developer Iron Dog Studio. This is one of a number of slots which feature an underwater-themed setting, which will entrance and delight sea loving players. It’s all very relaxing, until you get close to some sizable cashouts, of course. Then the nail-biting begins.

The free Siren’s Kingdom slot is a classic styled 5 x 3 layout, with 30 pay lines to play. It offers a return to player percentage of just over 96% and the level of variance is medium to high. That means you could be in with a chance of landing some big wins on this one. The jackpot is a maximum of 150,000 coins and you can start your bet from 0.30, up to a high limit of 150 coins (the more you play the more you could pocket). 

Overall, did our Siren's Kingdom slot reviewers find a hidden gem in a sea of slots? Read on to find out.

Finding the Pearl in the Ocean

This new online slot focuses its design on beautiful mermaids, along with a sense of drama reminiscent of a Disney film. It has a majestic soundtrack and appealing animations, based on a feminine color scheme of aqua blue, pastel pinks, and golds. Underwater-themed slots are tried and tested favorites among punters, and our Siren's Kingdom slot reviewers think that this good-looking version is bound to get some attention.

Framing the delicately drawn reels are two golden squid, while symbols on the board start with the lower value alphanumerics: A, J , 10, K and Q. There are various beautiful shells, a starfish containing a shiny pearl, and the crowned siren herself is the wild symbol. The siren (or mermaid) wild will appear on any top position of the reels, and substitutes for all symbols except the free spin symbol. These wilds pay as if they were the highest paying symbol on any line and you can land more than one at a time. There’s also a free spins symbol, as represented by a golden octopus holding a pearl aloft – although an oyster would seem to make more sense.

Our reviewers tested the Siren’s Kingdom video slot on all devices and confirm that you can play it anywhere with WiFi, whether you prefer spinning on desktop, tablet or your mobile device. The latest JS and HTML5 software technology used by Iron Dog Studio ensures that the spin mechanism flows seamlessly, and that the graphics are as fluid as the ocean in which the game is set.  

A Sticky Siren

The legend of the siren, stems from Greek mythology. In great works of literature (such as Homer’s famous piece, The Odyssey), alluring creatures who are half-fish, half-woman were said to sing to passing sailors. They would lure them toward an island with sweet tones, where the sailors would then face certain death.

Mermaids are essentially the same type of being, except they tend to be themselves doomed to stories of unrequited or impossible love – perhaps their comeuppance for their naughty antics in Grecian culture. Lucky for our Siren’s Kingdom slot review team, this game seems little concerned with singing or driving passersby to their death. Instead, these sirens represent good luck and the likelihood of greatly increased winning combinations.

Unlock the bonus round by landing 3 of the golden octopus free spins symbols in combination. You'll then be awarded 14 free spins. But, land 4 or 5 in combination and you will get 25 or 36 free spins respectively. During the free spins round, the wild takes on magical mermaid properties – she becomes a sticky wild when she lands. She will then expand in two different directions on the second spin, after which she will disappear, having given you the potential for some very big wins in the process.

An Iron Dog Studio Slot

The creatively named Iron Dog Studio, is an independent software developer with a relatively small, yet effective catalog of slot machines. Their titles are a mixture of popular themes and more imaginative, less overdone themes. Our reviewers feel that if you enjoy the Siren’s Kingdom slot machine, it’s certainly worth checking out more of their games. Their Neon Jungle slot is one such unusual venture, transporting players to lush, jungle regions, with a disco styled edge and beautiful graphics. This also has a 3 x 5 layout, but 10 less paylines than Siren’s Kingdom and atmospheric sound effects that contribute to the escapism provided by Iron Dog Studio Slots.

However, if you prefer to stick to the mainstream in terms of your choice of themes, slots and software developers, try Mermaid Millions. This comes from Microgaming, one of the biggest studios in the business and has another great RTP of 96%. The graphics contrast with Siren’s Kingdom, in that they are old school cartoon in style. But the game also has a familiar 3 x 5 layout, with less paylines at 15. Trigger the free spins round in Mermaid Millions by landing 3 or more mermaids and bet anything from a low limit of 0.01 coins, going up to 75 coins.

You Won’t Be Dashed on the Rocks

If you are wagering your hard earned cash in a real money casino, you want to know that could get a decent return on it. Overall, our Siren’s Kingdom slot reviewers think that this game offers a great combination of amusement with prizes, backed up with a high RTP and the excitement of a good deal of variance. That and the betting range will appeal to high rollers and experienced punters, while the simplicity of play and filmic qualities make it accessible to less accomplished slot players too.

This slot certainly doesn’t lure you in and then dash you against the rocks. It may be as beguiling as the sirens of Greek mythology, but it comes up with the goods and could end up offering you plenty of bang for your buck. It is more suited to those who appreciate a feminine style design, but with plenty of drama locked into the spins. It’s the sticky and expanding wilds that do the work for you here. And between the money-making chances they proffer and the dreamy graphics, these are some sirens worth taking a risk on.
