Siren Song Online Slot Review

Yggdrasil has a new title, a product of its YG Masters program, developed by TrueLab Games, called Siren Song. If you know the legends, you know that sirens were singing songs to allure pirates to their doom, so you should expect this title to be a bit dark, evil even, in terms of theme and its representation.

But not so much when it comes to payouts. This slot offers a classic 5x3 grid and 25 paylines, a decent RTP of 96.33%, and huge payout potential. Considering its high volatility, the slot can deliver excellent prizes, thanks to the three types of Free Spins, the Steering Wheel of Fortune and the Buy Bonus option. Dare to face the mermaids at the top New Jersey and Pennsylvania slots sites?

How to Play Siren Song Slot

We must start this Siren Song review by telling you that you’ll be able to play the slot across any device. Whether you prefer doing it on the go or while at home on your desktop device, the slot plays perfectly on any device.

As you load the game, you will see that that it is set deep underwater. The reels are transparent, and the control buttons are below them. Going from right to left, you first see the Balance and Win displays, followed by the Free Spins display and the Cash Bet display. Then, you have the wager configuration field, where you can place a wager from 0.25 to 50 credits, followed by the lines display, always showing 25, since that’s the number of fixed paylines active.

The last one on the far left is the + button. Clicking or tapping on it, you see the pop-up tab displaying several buttons. The first one from the top is the Speaker, where you can enable or disable the sounds of the game. Next, is the Settings button, where the game's settings are, followed by the Game Rules button and the "i” button, where the paytable is.

You first see the emerald, silver and crimson sirens which will play the role of Nudging Wild symbols, and appear on the 1st, 3rd and 5th reel only, always nudging to occupy the whole reel. Then you see the Pearl as the Scatter. The two regular Wilds are the Pirate and its skeleton counterpart. The highest-paying symbol is the harp, the second-best fish, followed by the medium-paying glowing sea creatures and the low-paying playing card Royals from A through J.

Siren Song Bonus Features and Free Spins

We need to start this overview of features by telling you that there are three Siren Song bonus games you can choose from. The Free Spins are triggered when you land Scatters on the 1st, 3rd and 5th reel, and each type arrives with 8 Free Spins.

The lowest volatile one is the Crimson Free Spins. You play through the 8 Free Spins and collect the key symbols that appear. Then you go to round two, where another screen appears with chests you need to open, to reveal Multipliers of 1x to 500x, extra keys or values that increase the Win Multiplier.

The Emerald Free Spins are the medium volatile bonus round, where skeleton Wilds become Sticky when they land, staying on the reels for the remainder of the Free Spins.

The highest volatile type is the Silver Free Spins. The Silver Siren will appear and toss 4 to 20 fish symbols on the reels, on each spin. If more than one fish lands in the same position, the Multiplier increases. Three fish equals 3x, four equals 4x, etc. As you remember, the fish are the second-best paying symbols, giving you 30x the stake for a 5-of-a-kind combo.

When the Free Spins you chose end, you get a spin on the Steering Wheel of Fortune. It gives you a chance to multiply the total you’ve won during the Free Spins by 2x to 10x, or scoop an additional prize of 5x to 100x the stake!

You’ll also get the opportunity to purchase your way into the Free Spins, thanks to the Bonus Buy option available in some jurisdictions, for a 127.6x the stake cost.

Lastly, we need to mention that both the Nudging Siren Wilds and the regular Wilds substitute for all symbols bar the Scatter, helping you form better wins!
