Shipwreck Specs

TrueLab launched Siren Song on 22 July 2021, dropping a cold splash of Mythology in the middle of its catalogue. The grid uses 5 reels and three rows, and all wins pay from the left across a fixed set of 25 paylines. Stakes begin at €0.25 and stop at €50, so even a cautious sailor can test the current. Audio leans on distant whale groans and creaking masts; it is eerie yet oddly calm, though headphones reveal a bass rumble you might miss on laptop speakers. Chests, anchors and golden lyres handle mid-pay duties, yet the sirens themselves—emerald, silver, crimson—own the premium spots, returning up to 12× stake for a five-oak line. Mobile performance looks tidy on my six-inch Android, but the spin button feels smallish if you have fat thumbs.

Sirens On The Screens

Wild sirens can land part-height; they instantly nudge to fill the reel, which keeps base play lively. Pearls work as the Scatter; collect three in one spin and you dive straight into a feature set that splits three ways. Behind the art sits a towering top win of x30,000 and, yes, that number is real—TrueLab posts the actual seed so no marketing puff here. What did surprise me is how often smaller hits string together; a crew mate of mine tracked roughly 31 % hit rate over 500 rounds, which softens the long dry spells you expect from a slot flagged high volatility.

Math Under The Waves

The advertised RTP is 96.33 %, a shade above the line where I start frowning. TrueLab, unlike some big brands, ships one single maths file, so rogue casinos cannot drop the pay-back behind your back. Still, remember the house keeps 3.67 % on average; that is fine, yet not outstanding. Because of the brutal variance, I suggest at least 600 base bets in the tank before you even sniff the buy button—anything less and you risk washing up broke before the first feature fires.

Emerald, Silver Or Crimson? (Free-Spin Modes)

Landing 3 pearls lets you pick one of three 8-spin modes:

• Emerald Spins – Skull Wilds turn Sticky for the whole bonus, which can snowball line wins in the last few spins.
• Silver Spins – each round calls 4-20 fish to random cells; if several fish stack, they grant a cell Multiplier matching their count.
• Crimson Spins – Keys are added to the reels; every key triggers the Pick & Click at the end.

In my own play, Silver felt swingy, Emerald steady, Crimson downright feast-or-famine. Pick what fits your mood (or your remaining balance).

Crimson Pick & Click (Bonus Game)

Collect at least one key in Crimson mode and a 10-chest screen pops. Eight chests hide instant bet prizes, one hides extra keys (up to 3), and one doubles the running multiplier for anything you open afterwards. It is quick, maybe 30 seconds, yet a lucky double multiplier can turn an okay bonus into something that makes you yell at the monitor. I like how the game shows the chest odds right there, no scrolling the pay-table. Small detail, nice touch.

Instant Passage To The Deep (Buy Bonus)

If patience is not your thing, you can smash the Buy Bonus game button for exactly 127.6× stake. The purchase picks a random siren, so there is no way to target Crimson every time. I tried it three times; one paid 5×, one 62×, and one 410×. Variance is wild, and the price tag is steep, so only use it when you are rolled high enough to shrug off a dud.

Wheel Of The Drowned

No matter which siren mode you finish, the Steering Wheel of Fortune spins once. It can:

• add a win multiplier of x2 – x20 to the total bonus haul
• drop an extra bet prize up to 50× straight into your pocket

I have hit x2 four times, x5 once, still waiting for the big numbers. Even so, the extra sweat after the free spins keeps the adrenaline up.

Other Tidal Tricks

• Scatter symbol – the pearl also carries a 100× line prize for five, nice side income when it happens.

• Nudging Wild – every siren wild always expands; simple rule yet feels good when it rescues half-made combos.

• Sticky Wild – active only in Emerald mode, but seeing a column lock from spin 1 is tasty.

Pros And Cons

Pros:

• Three distinct free-spin modes add proper strategy
• Max win pushes a fierce x30,000 ceiling
• One RTP version, no silent downgrades
• Buy feature offered for those with big bankrolls
• Art and background score build a thick ocean vibe

Cons:

• High swings will sink short stacks fast
• Buy Bonus price feels heavy at 127.6×
• Wheel multipliers below x3 show up too often in my view
