What does John have to say?

While Siren Song’s option to choose between 3 different sets of free spins, each with their own unique twist and level of volatility may seem intriguing on paper, the reality isn’t quite as peachy. The lowest volatility option turns out to be the most intriguing and with very little else on offer, the slot’s shelf life feels quite limited.
  • 3 Free Spins options
  • Wheel of Fortune feature can offer a great bonus
  • Maximum win of 30,000x
  • 2 of the 3 Free Spins options are quite lacking
  • Not enough variety of features available

Siren Song Slot Review

Yggdrasil team up with TrueLab Games for their mythological, underwater adventure, Siren Song.

Rather than sticking to the siren’s ancient Greek roots, the slot’s theme visits a slightly more recent period in time, with pirates making an appearance. The visuals are of a high quality, with animations and music, giving the slot a very distinct character, even if the screen feels quite bare most of the time.

But questionable visuals aside, what does Siren Song have to offer players who dare listen to its haunting tune? Check out our full video slot review below to learn all about Siren Song and the 3 free spin variations it has to offer!

Siren Song Bonus Features

With an emphasis on free spins, Siren Song doesn’t put much stock into the slot’s base game. Sure, you’ll get high paying symbols and wilds that carry that same high value, but all in all, the main game can be quite a drag. Free Spin on the other hand is quite enticing, offering players a choice of 3 variations to play from whenever they’re triggered.


Wild symbols turn up in the form of a fierce pirate or his skeletal counterpart. Both symbols are identical in function, stepping in for any missing symbols that can form part of a winning combination. They also carry the highest value in-game, equal to that of the barnacled harp at 60x.

Scatter Symbol

Pearls represent the game’s Scatter symbols and players will need a total of 3 to trigger free spins. Once activated, players are awarded 8 bonus rounds and can pick from three variations of the bonus segment.

Free Spins

On triggering the bonus rounds, players are able to pick one of the following free spins versions:

  • Silver Free Spins – At the beginning of every spin, the siren will throw in up to 20 fish symbols onto the reels. Multiple fish symbols landing on the same position offer a multiplier based on the number of fish present. So, 2 fish symbols on each other offer a x2 multiplier while 3 symbols grant a x3 multiplier. Fish symbols carry a x30 value for 5 of a kind. This is the most highly volatile option of the three.
  • Emerald Free Spins – The simplest of the options available, this version makes all skeletal wilds that fall on the reels sticky and will remain there until the end of free spins. This options carries a medium level of volatility.
  • Crimson Free Spins – During free spins, the crimson siren will collect all key symbols to land on the reels. Once the 8 spins are over, players are transferred to a pick me bonus. Here they get to use the keys they collected to unlock treasure chests of their choosing and take the multipliers that lie within.

Steering Wheel of Fortune

Regardless of what version players pick, whenever Free Spins ends, players are treated to the Steering Wheel of Fortune. One spin on the wheel can land you a chance to win 5-100x your current stake or even a multiplier of up to 10x that applies to your free spins wins.

Buy Feature

If you don’t particularly enjoy waiting for all 3 Scatter symbols to drop onto your reels, you can always opt for the Buy Feature for 127.6x your current stake.

Siren Song Jackpot

There is no dedicated jackpot feature in Siren Song. Players can still dream big though, thanks to the slot’s 30,000x maximum win amount.

RTP & Volatility

Clocked at a high volatility setting, Siren Song offers players a 96.33% return to player rate. It’s a balanced math model, although players shouldn’t be expecting any consistent wins to come their way.
