Queen of Sirens slot: Siren Queen Bonus Chase
Queen of Sirens slot plays like a compact bonus chase, not a normal payline game.
According to Evoplay, Queen of Sirens is a high volatility slot with 95.97% RTP and 4,313x max win potential. It uses a 3×3 grid where the base game pays nothing until bonus symbols trigger the feature. It targets patient bonus hunters who can handle bonus-or-nothing pacing and want a simple hold-and-win style chase.
Key takeaways
- Best play: Treat Queen of Sirens slot as bonus-dependent because ordinary base-game symbol wins don’t pay.
- Best bonus: Bonus Game costs 30x total bet, Ultra Bonus Game costs 75x, and I didn’t test either buy.
- RTP / volatility: The 95.97% RTP pairs with high volatility, so dry runs can happen.
- Max win: The cap is 4,313x the bet, while the Grand Jackpot pays 500x when all 9 positions fill.
- Bankroll note: Smaller stakes make sense because most non-feature spins remove one bet.
Fast Fact: All meaningful payouts in my test came from the Bonus Game. The other 96 spins in the 100-spin run paid nothing.

How Queen of Sirens slot Works
Queen of Sirens works through bonus symbols, not regular line wins. The base game only starts the payout engine when three bonus symbols land on the central fixed line. You should treat every spin as a hunt for the feature, because the board doesn’t pay ordinary matches.
Core payout rules
There isn’t a normal paytable here. Every symbol on the 3 reels by 3 rows board is a bonus symbol, and none pays by itself in the base game. You get paid only through the Bonus Game or Ultra Bonus Game, which makes the game feel blunt but easy to understand.
That one fixed line matters for triggering, not for paying line wins. Three bonus symbols on the middle row start the Bonus Game, then the round collects values. Gold of Sirens gives sea-themed coin-and-jackpot fans a broader comparison point, but this game feels more stripped down and feature-led.
The compact 3×3 board should read clearly on desktop and mobile because all important values sit on the small grid. I like that clarity. You don’t need to scan a busy reel set while waiting for one key line to land.
Coin and jackpot values
The Bonus Coin is the common gold coin and carries 1x, 2x, 3x or 4x the bet. The Sticky Coin is red and carries 5x to 9x the bet. Mini, Minor and Major jackpot coins pay 10x, 20x and 50x the bet, while filling all 9 positions pays the Grand Jackpot at 500x.
Two special symbols add the real shape. The Octopus has no value of its own and works as a collector, while the Mystic chest turns into another symbol after the round closes. The gold Mystic Jackpot chest always contains Mini, Minor or Major.
In practice, Queen of Sirens asks you to care about where symbols land and when they land. You won’t get small symbol wins to soften the wait. Every later feature matters because the base game itself doesn’t create normal symbol payouts.
Theme & First Impressions
The theme is a clean underwater hold-and-win setup with a red-haired mermaid queen and a small gold-framed grid. You can read the jackpot chase quickly because the screen keeps almost everything near the board. That matters when you need to spot middle-line triggers fast.
Underwater layout
The scene uses a sea-floor temple background, a glowing shell on the right, and a red-haired queen figure beside the grid. Four jackpot prizes sit above the board: Grand, Major, Minor and Mini. In my demo screen, the balance showed $5,220 and the bet sat at $10.
Every amount in those screens works as a multiple of the bet. I don’t love play-money labels in serious testing, but they make the session easy to track. You can follow the rises and drops without converting anything into another unit.
Red Queen may appeal if you enjoy character-led royal slots with a stronger portrait focus. This game, by contrast, leans harder into a queen of the sirens idea, with the mermaid, shell and temple doing most of the visual work.
First visual read
The theme won’t win originality awards, but the compact layout makes the bonus chase easy to read. You might find that more useful than a busier underwater scene. I did, because the game gives little feedback until bonus action arrives.
The siren theme comes through most clearly in the mermaid queen, glowing shell and sea-floor temple setting. It doesn’t rely on a long story sequence. The design supports fast reading, which matters because the game turns on bonus-symbol positions.
Sticky Coin
The Sticky Coin is the red coin that can stay on the reels before a bonus starts. It matters because changing your stake clears it from the board. If you already have red coins sitting there, you need to think before touching the bet controls.
Sticky values
The red coin carries 5x to 9x the bet, so it starts higher than the common gold coin. When it lands in the base game, it stays on the reels until a Bonus Game or Ultra Bonus Game starts. Multiple Sticky Coins can build up while you spin.
That persistence gives the base game its only real sense of build-up. You still don’t get paid unless a feature starts, but you can see potential value sitting on the board. I liked that small hook because it makes dead spins feel less empty when a Sticky Coin appears.
Bet-change warning
Changing the bet clears Sticky Coins from the reels. That rule makes stake discipline more important than usual, since one casual bet change can wipe out a board you were building. You should set your stake before you settle into a run.
Tip: If Sticky Coins have built up, avoid changing the bet unless you deliberately want to reset the board. Pick a stake you can leave alone through cold stretches.
This feature doesn’t make the base game generous. It only gives you a visible reason to stay consistent. Set the stake first, then let the run breathe.
Bonus Game, Octopus and Mystic Symbols
The Bonus Game is the main payout engine. It starts when three bonus symbols land on the central line, then pays the collected values at the end. You won’t see normal line payouts before that, so the feature carries almost the whole experience.
Trigger and reset
Any 3 bonus symbols on the central line trigger the Bonus Game. The triggering symbols stay in place, and the round begins with 3 spins. Every new bonus symbol resets the counter to 3, so one late drop can extend the round again.
Every landed bonus symbol stays on the board. The round ends when spins run out or all 9 positions fill, then it adds all symbol values into one payment. The round plays at the same bet as the triggering spin, which keeps the math simple.
In my test, the bonus total was where the game finally gave feedback after empty base spins. That rhythm won’t please everyone. You spend long patches losing one bet at a time, then the feature decides whether the wait feels fair.
Octopus collector timing
The Octopus can appear in the base game, Bonus Game and Ultra Bonus Game. It has no value of its own. In the base game, it counts as one of the symbols that can start the Bonus Game.
During a bonus round, the Octopus collects all values and jackpots from symbols that landed earlier in that round. In my test it showed up with a 20 on it, which matched two 10-value coins already on the board. That little moment made the landing order feel important.
Trivia: The order symbols land in matters because the Octopus only collects values and jackpots already on the board. A late Octopus can matter much more than an early one.
Mystic chest reveals
The Mystic chest transforms when the Bonus Game or Ultra Bonus Game ends. It can turn into any other symbol except the Sticky Coin. The Mystic Jackpot chest uses the same delayed-reveal idea, but it contains Mini, Minor or Major.
These symbols make the ending more interesting than the middle sometimes suggests. You may stare at a modest-looking board, then wait for chests to reveal the real total. Gold of Sirens Bonus Buy is a useful comparison if you care about Sirens-style feature access, though I didn’t test either buy here.
I found the round simple to follow, and that simplicity helps. Still, the result depends heavily on late symbol drops, collector timing and delayed reveals. The feature feels clean, but it can still swing hard.
Ultra Bonus Game and Luck of Aurora
The Ultra Bonus Game is the stronger bonus version because it can start randomly with extra setup already in place. Luck of Aurora then adds cell multipliers that can turn later symbols into bigger pays. You get a higher-ceiling feel without changing the basic round rules.
Random start
The Ultra Bonus Game can start at random from any base-game round. Before it begins, 3 or more random symbols are placed so the central line fills. That setup fits the bonus-led pacing, because the game already trains you to wait for feature action.
Luck of Aurora is always active at the start of the Ultra Bonus Game. It also fires more often than in the normal Bonus Game. I wouldn’t treat that as a promise of a big result, but it gives the round more ways to build tension.
Stronger setup
The rest of the Ultra Bonus Game follows the normal Bonus Game rules. New bonus symbols reset the counter to 3, landed symbols stay, and the final total pays in one go. The difference is the starting shape and more frequent multiplier activity.
Wheel of Time fits a different mood if you enjoy random feature events and waiting for major bonus-led moments instead of frequent base-game wins. Here, the tiny grid keeps the drama tighter. You watch nine spaces and hope the right cells become valuable.
Cell multipliers
Luck of Aurora can activate during the Bonus Game or Ultra Bonus Game. It fires 1 to 9 fire comets at random cells, leaving a 2x multiplier on each hit cell. If a cell already has a multiplier, each extra hit increases it by 1.
The multiplier belongs to the cell, not the symbol. What lands there later can matter more than what sat there first. Whatever symbol sits on a multiplied cell gets multiplied when the total pays.
I like this layer because it adds suspense without making the rules messy. You can understand it in one glance, but the timing still matters. This feature gives the game its sharpest swing potential without making base spins pay normally.
Bonus Buy Options
The Bonus Buy options give direct access to the only meaningful payout engine, but they also concentrate risk. I did not buy either option during the short test. That matters, because I can’t call one buy better from lived results.
Buy costs
The Bonus Buy button appears on the left. The Bonus Game costs 30x total bet, while the Ultra Bonus Game costs 75x. After you confirm a purchase, the reels spin and fill the central line with at least 3 bonus symbols.
Then the selected round starts under its normal rules. Since normal base spins pay nothing unless a bonus starts, the buys skip the waiting. They also put more pressure on every result, especially if several rounds end low.
Queen of Sirens slot lets you inspect the buy panel in demo or real play on SatoshiHero. I prefer checking that panel at a small stake first. You should know the exact cost before you press anything.
Test limitation
I didn’t buy the Bonus Game or Ultra Bonus Game in this run. My 100-spin result came from natural triggers only, so the buy options remain a rules observation rather than a tested edge. That honesty matters more than pretending I learned something I didn’t.
Alert: A 75x Ultra Bonus buy can drain a demo or real balance quickly if several rounds land low. Size your stake before pressing buy.
The buys make sense only if you accept concentrated bonus-round risk. You get faster access to the feature, not a shortcut around volatility. I would treat them as high-pressure choices, not routine spins.
RTP, Volatility & Our Test
The math points to a swingy bonus-led slot, and the short test showed exactly that pattern. The official return is 95.97%, volatility is high, and the maximum win is 4,313x the bet. You should expect sharp gaps between meaningful events.
Simulator projection
I ran 1,000 spins at one bet unit using the return, volatility and cap as inputs. The median session finished 69x my bet down. Nine runs in ten ended between 321.1x down and 361.4x up, which shows a wide spread.
Around 18 spins in 100 returned something in the model. A feature-sized hit appeared about once every 45 spins, while a win of 100x or more appeared about once in 1,761 spins. That model shows a range, not your next result.
If you came looking for queen of sirens wiki-style facts, the key numbers sit in one tight group. The math backs up the feel: bonus action drives the game, and empty spins form the baseline. You can get a fun burst, but the wait does the heavy lifting.
Our 100-spin session
I played 100 spins in turbo mode at the default bet of $10. My balance moved from $5,000 to $5,220, so I finished 22x my bet up. Every bit of profit came from Bonus Game results.
The feature triggered on spins 18, 61, 72 and 91. Those rounds paid 82x, 7x, 18x and 15x the bet. The other 96 spins paid nothing at all, which is the bluntest lesson from my session.
My biggest hit was the first bonus round at 82x. It lifted the balance from $4,820 to $5,630, then the graph stepped down one bet per spin until the next feature caught it. That shape matched the game’s bonus-only design perfectly.
Four triggers in 100 spins was luckier than the simulator average of roughly one feature-sized hit per 45 spins. I read this as a lucky snapshot, not a signal that the game is gentle. You might get the fun version, but you still need room for the colder one.
Theoretical RTP is the operator-published figure. A single live or demo session doesn’t change that return. Bonus-buy and feature outcomes can feel different from base-game pacing by design, so the 100-spin result shows how this test played, not what your next session does.
The tested win was useful, but it shouldn’t hide the empty-spin rhythm. You get clarity, drama and quick bonus totals. You also get long stretches where the balance simply steps down.
Who This Slot Suits
This slot fits patient bonus chasers who can wait through empty base spins. It doesn’t fit you if you want regular line wins or frequent small payouts. You need to enjoy the chase more than the base-game drip.
Player fit
High-volatility hunters and hold-and-win fans get the clearest value here. The small grid keeps the rules visible, and the jackpot targets stay easy to track. You won’t need a complex paytable, which I see as a strength.
That same simplicity can feel severe. If you like base games that return small hits often, this one may feel cold. I liked how readable it was, but the dead base game means you need to be in the mood for waiting.
Queen of Sirens slot also works for players drawn to one feature carrying the whole session. The test finished up only because four Bonus Games landed inside 100 spins. Without those triggers, the same run would have felt rough fast.
Bankroll feel
The bankroll feel is direct and sometimes harsh. Non-feature spins simply remove one bet, so a smaller stake gives you more room to wait for the bonus. You should think in blocks of spins, not one lucky press.
I would start lower than usual here, especially if Sticky Coins appear and tempt you to keep the same stake. That isn’t a magic tactic, but it gives you breathing room. Patience matters more than complicated decisions.
The game is clean and readable, but it asks for patience. You can get a sharp bonus jump, as my first round showed. You can also watch many spins do nothing before the grid finally wakes up.
Frequently Asked Questions About Queen of Sirens
How many paylines does Queen of Sirens slot have?
Queen of Sirens slot has 1 fixed payline on a 3 reel by 3 row grid. The base game pays nothing on that line. Three bonus symbols on the central line start the Bonus Game, and every value is paid in the bonus.
What does the Octopus do in Queen of Sirens slot?
The Octopus has no value of its own. When it lands in a bonus round, it collects all values and jackpots from the bonus symbols that landed before it. In the base game, it counts as one of the symbols that can start the Bonus Game.
What are the jackpot prizes in Queen of Sirens slot?
There are four fixed jackpots, and they can only be won in the Bonus Game. Mini pays 10x the bet, Minor 20x, Major 50x and Grand 500x. Filling all 9 positions with bonus symbols pays the Grand Jackpot.
What is the maximum win and return to player of Queen of Sirens slot?
The top win is 4,313x the bet and the return to player is 95.97%. The volatility is high, so long dry stretches broken by bonus rounds are normal.
How did the 1,000 spin simulator compare with my own Queen of Sirens run?
The simulator’s median session finished 69x my bet down, with nine runs in ten between 321.1x down and 361.4x up. My own 100 spin run finished 22x up, thanks to four Bonus Games. That was about twice as many triggers as the model’s one in 45 average would suggest.
How did the 100 spin Queen of Sirens slot test go?
I started with $5,000 at a bet of $10 and finished on $5,220, which is 22x the bet up. The Bonus Game triggered four times and paid 82x, 7x, 18x and 15x. Every other spin paid nothing.
How much does the Queen of Sirens slot Bonus Buy cost?
The Bonus Game costs 30x the total bet and the Ultra Bonus Game costs 75x. Both start with at least 3 bonus symbols on the central line. I did not buy either one in this test.
Closing Thoughts
Queen of Sirens stands out because it commits fully to the bonus chase. The small grid, Sticky Coins, Octopus collector and delayed chest reveals keep the feature easy to follow. The main drawback is clear too: the base game can feel empty.
My Verdict
Patient bonus chasers can have fun here, especially if they like simple hold-and-win rounds. Expect quiet base spins, sudden bonus jumps and a real need for stake control. I wouldn’t play it when I want frequent small wins.
I like the readability and the way the first 82x bonus changed the whole test. I don’t like how the other 96 spins gave no payout at all. That trade-off defines the game more than any visual flourish.
Queen of Sirens slot deserves a place on your shortlist if you want a compact feature hunt with clear risks. This guide is checked regularly as tested mechanics and SatoshiHero game pages change.
