Queen of Sirens Slot Review
Mel Fisher lost 16 years and a son to a Spanish galleon called the Nuestra Senora de Atocha, and the part nobody puts on the documentary poster is how much of the search was digging up sand 💰 and finding nothing in it.
He remortgaged his own life to keep the boats out there. Every morning his crew said “today's the day,” and for 5,844 days straight they were wrong.
Then in 1985 the debris field finally coughed up silver and emeralds worth hundreds of millions, and the obsession suddenly looked like a business plan instead of a breakdown.
That's the trade you're signing up for: long stretches of pocket change, then a round that justifies the whole thing.
Now, Queen of Sirens slot from Evoplay? Same math, a 3x3 grid 🧜♀️, coins landing one at a time while a mermaid queen and an 🦪 oyster shell watch it happen.

Gameplay
Evoplay kept the set dressing thin on purpose. A red-haired mermaid queen stands next to the gold-framed reel screen, a glowing oyster shell and some stone columns handle the background, and none of it moves between spins.
The scene doesn't need to hustle, since the whole game lives in the 4 jackpot ribbons above the grid and whatever coins drop inside the grid.
The layout is 3x3 with no paylines and no ways, and that's not a typo.
Ordinary spins pay out nothing by themselves; nothing counts until the Bonus Game or Ultra Bonus Game resolves. Every symbol on that board exists only to trigger one of those rounds, or to sit on the grid waiting to feed it.
The RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.
RTP needs to be considered in conjunction with a game’s volatility rate. is 95.97%, volatility is High, and the max multiplier tops out at 4,313x for a max win of $323,475.
Bets run from $0.20 up to $75.
Small change makes up most of what lands. The Bonus Coin symbol turns up on ordinary spins, in the Bonus Game, or in the Ultra Bonus Game, worth a random 1x, 2x, 3x, or 4x the bet whenever it counts.
The Sticky Coin symbol pays better at 5x, 6x, 7x, 8x, or 9x the bet. Land one on a normal spin and it locks to its cell, staying there through whatever Bonus Game or Ultra Bonus Game eventually starts.
The Mystic symbol and the Mystic Jackpot symbol hold their answer until the very end, since neither resolves until the round is over.
Every Mystic symbol is a placeholder: at the finish it copies whatever's already on the board, anything except the Sticky Coin. The Mystic Jackpot symbol always becomes the Mini, Minor, or Major jackpot.
The Octopus symbol carries no value of its own, but it still pulls its weight. It can turn up on ordinary spins or during either bonus round, and counts toward the 3 symbols the central row needs to kick a round off.
Land one mid-round and it sweeps the table, banking every coin and jackpot value that touched down before it.
Four fixed jackpots sit above the reels: Grand at 500x, Major at 50x, Minor at 20x, and Mini at 10x.
A Mini, Minor, or Major Bonus symbol hands you the matching jackpot. Fill all 9 positions with Bonus symbols of any kind and the Grand Jackpot is yours.

Features
BONUS GAME:
Any 3 symbols on the central row start it. You get 3 spins, and every fresh Bonus symbol that lands puts the counter back to 3.
Every Bonus symbol that lands stays put until the round ends, stacking toward the final total. The round keeps going until the spin counter hits zero or Bonus symbols cover the whole board.
Once it ends, whatever's sitting on the board gets added up and paid out as one number.
Luck of Aurora
This fires at random during the Bonus Game and sends 1 to 9 comets into random cells, each leaving a 2x multiplier behind.
Landing a second comet on a cell that already carries a multiplier adds 1 to it instead of replacing it, so a cell the comets keep favoring climbs to 3x, 4x, 5x.
None of those multipliers shift once they land. Each one waits out the round, then applies to whatever coin ends up parked on its cell.
ULTRA BONUS GAME:
The Ultra Bonus Game triggers at random on any base game spin. You start with 3 or more symbols already placed on the central row.
Luck of Aurora switches on automatically at the opening and fires more often across the round than it does in the standard Bonus Game.
BUY BONUS:
The Bonus Game costs 30x the total bet. The Ultra Bonus Game costs 75x.
Performance
Not one glitch across a long test session. Coins landed and the board cleared cleanly every round.
Maximum Win
The max win is $323,475, reached at a max multiplier of 4,313x and the $75 top bet, with the range starting at $0.20.
Conclusion
Luck of Aurora is the engine here, not the coins themselves: stack enough multipliers onto the same handful of cells and the number sitting there at the finish is what pays out.
Coins alone won't carry you. Comets alone land on nothing. You need both in the same cells.
Getting anywhere near 4,313x means the board fills almost entirely with the biggest Sticky Coin values while Luck of Aurora keeps landing on those exact same cells before the spins dry up.
That isn't a climb you can force. It's a run that has to keep picking the same squares, over and over, on its own.
Let's be honest about the RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.
RTP needs to be considered in conjunction with a game’s volatility rate.: 95.97% sits under the 96% line that marks a longer-session game.
That means playing in short, well-funded bursts instead of parking here for hours.
The High volatility brings the swings you'd expect, but 4,313x sits below where High-volatility ceilings usually land. You're taking the full risk for less than the full reward.
The Buy Bonus is a shortcut past the wait for a natural trigger. The cheaper option gets you nothing but skipping the queue.
Only the pricier option buys you a mechanic rather than time: the Ultra Bonus Game's guaranteed head start and its heavier Luck of Aurora rate.
Worth it if you specifically want the multiplier density; otherwise it's an expensive fast pass.
Queen of Sirens slot suits big-bet players chasing a rare stacked-multiplier round; anyone betting small and hoping for frequent little wins should skip it, since nothing pays outside the 2 bonus rounds.
