Siren Song By TrueLab Games For UK Online Slots

TrueLab Games tapped into every sailor’s fear with their mythical online slot game, Siren Song UK Online Slots. Legend has it, beautiful mermaids would attract sailors before causing their ships to crash into rocks and sink.


The 5 x 3 reel set is set in the murky depths of the ocean, the 3 enchanting mermaids can appear as stacked symbols to make it easier to create winning combos with them. If your spins work in your favour, you will be able to bank up to 30,000x your stake, but spin this slot with caution, the volatility can be just as dangerous as the mermaids!

Payouts And Symbols

Stick to the lower end of the 25p - £50 betting range to ensure smooth sailing if you’re planning on a lengthy spin session. *The mesmerising video slot comes with 25 pay-lines, a 96.33% RTP and plenty of bonus features including the wheel of fortune feature, a free spin feature that gives you 3 different ways to play and wild symbols.

Bonus Rounds

Stacked Mermaid Wild Symbols

Each of the three mermaid symbols can appear as a stacked 1 x 3 symbol. If they only land partially in view, you will activate the nudge feature to help them fill the entire reel. The mermaid wild symbols can substitute for all symbols bar the scatter symbols.

Free Spin Bonus Feature
