Siren Song is a brand new slot machine that’s designed by TrueLab Games, as part of the YGS Masters program from Yggdrasil Gaming. Great graphics, huge top jackpots, extreme volatility, you get it all in this pirate and siren themed slot machine, which looks like it’s designed especially for the veteran players.

A game where you could walk away with a jackpot of up to $1 million (30,000x the stake is the other cap), Siren Song will offer only 25 active lines on 5x3 reels, to get you there. Highly volatile, with the RTP at 96.33%, it looks like a good option for a player that is experienced enough to know what he (or she) is getting into. Major features range from the two types of wilds, to the scatters and free spins, and even some multipliers that could apply to all wins.

Siren Song Betting and Prizes

As usual, you can spend little and still play this slot game. $0.25 is going to be the minimum, while $50 is the maximum.

As for the returns on your wagers, up to 30,000x the stake will be paid (capped at $1,000,000). Regular wins will not get you there, those pay up to 1,500x the stake (60x per line) during regular rounds. However, the free spins are another matter.

A game with a big return will typically have high volatility, meaning that you can lose your money fairly quickly. There are long dry-spells for a lot of players, while others may win immediately. RTP is 96.33%, so it’s a fair game overall, even though it might not feel like it.

Siren Song Slot Features

The Pirate is one of the two wild symbols that you can use, and it will act as a substitute. You can use it in combination with any of the regular symbols.

Second, there is a Skeleton Wild as well, which works in the same way, being a substitute for regular symbols. Both are used to also form combinations of their own.

Ultimately, the target is going to be the free spins feature. You need Pearls landing scattered three times, to get a choice of the type of free games that you prefer. All variants have 8 free spins, only the extra features differ.

  • Silver: up to 20 high value fish symbols (purple ones) are added to the game area, to hopefully form combinations. If several land in the same spot, then a multiplier applies to the win.
  • Emerald: Skeleton Wilds are sticky when they show up.
  • Crimson: you collect keys as you play, and then you get a bonus game where you use them to open chests. Up to 500x the stake can be paid by each chest, or you could get additional keys and higher multipliers.

Once your version of the free spins is complete, you get the Wheel of Fortune to spin once, and reveal either an additional prize of up to 100x the stake, or a multiplier of up to 10x to boost all wins obtained so far.

Theme & Design

It’s taking the player to the depths of the ocean, so the darker shade of blue from the background is understandable. A beautiful Siren is visible to the left of the reels, changing to their Queen during the free spins. Siren Song looks great, it’s a slot machine with mostly themed symbols on its reels, and the quality is high.

Symbols range from feature triggers with Pirates, Skeletons, and Pearls, to regulars. The latter include a couple of Royals (Jack to Ace) that were designed to match the theme, along with harps, and four creatures of the sea (conca shells, starfish, etc).


Siren Song slot is just one of the many games that you can try out at Yggdrasil-powered casinos, but I would only recommend it if you have a bit of experience, so you know how punishing a high volatility slot can be.
