How to Play Siren Song Slot

Set your bets before you go treasure hunting in this underwater kingdom. 

  • Bet Level +/- will let you either decrease or increase your bets.
  • Spin will get the reels moving once the bets have been set.
  • Max Bet will set the maximum allowed bet with one click.
  • Auto will open a panel and let you preset the number of automated, no-interruptions spins.
  • Buy Bonus will let you buy into the bonus round rather than waiting for it to trigger regular ways.

Slot Features

As you start going down deeper and deeper, you may run into the Sirens that serve the purpose of the Wild symbols that can sub in for all the others in the game, except for the Scatter. These Wild Sirens will always nudge to cover the entire reel.

Free Spins

Grab 3 Pearls along the way, on the same spin, and you will kick start the Free Spins round and each of the Sirens will represent a different mode – Emerald Spins, Crimson Spins and Silver Spins, with each having the ability to give 8 spins overall.

In Emerald Spins the Skull Wilds will turn into Sticky ones and hold their position till the round is over. In Silver Spins, with each spin you make, the Siren will call between 4 and 20 Fish symbols to get randomly placed on the reels. Several fish landing on the same spot will award a Multiplier whose value will equal to the number of fish in that position. Crimson Spins will have Key symbols added to the reels, and at the round’s end you get to play Pick&Click bonus, and the number of picks will equal to the number of keys you collect.

Crimson Pick&Click

In the Pick&Click you will get 10 chests at the bottom of the sea hiding random prizes. One chest is always the Key one, and it will award additional keys with cap up to 3. One chest is always going to be a Multiplier chest that will increase a multiplier for all the future bets by x2. The remaining 8 chests will award a random amount of bets multiplied by the current multiplier.

Steering Wheel of Fortune

No matter which Siren gets you to this round, you will get a Wheel to spin at the end of the Free Spins round. Once the Wheel stops, you will get a multiplier that will be applied to the wins you scooped in Free Spins round, or award and added bet prize.

Buy Bonus

In case you do not want to wait out to get the Free Spins triggered, you can always hit the Buy Bonus button and get the shortcut to it for 127.6 bets. 


Siren Song slot was a joint effort between True Lab and Yggdrasil, and if you ask us, it’s a match made in heaven. The design is impeccable and the game is packed with various features. Now, features, are not really innovative nor bursting with prizes, so you might not find that portion appealing, but the overall max win cap is set to x30000 the bet. It’s highly volatiles so arm yourself with patience before you take on this underwater mystery.
