Deep beneath the waves, the mermaids have made themselves a home far from human eyes. This sprawling underwater paradise is ruled by the Queen of Sirens, an otherworldly, redheaded beauty. She oversees everything that happens in the kingdom, so impressing her is a must. Become her champion, and you will be richly rewarded for your troubles.
Evoplay’s release looks impressive, but is it enough to win players over? Find out in our in-depth review of the Queen of Sirens slot.
Queen of Sirens Visuals & Sounds
The developer opted for a straightforward background, with tall pillars and distant structures that catch the eye. Everything else is a vast expanse of blue or the colourful ocean floor. Next to the reels, the Queen keeps track of your progress on the reels. She’ll applaud your success or start yawning if you leave the game unattended for long enough. She also casts spells that lead you into the game’s bonus rounds.
Queen of Sirens from Evoplay has unorthodox gameplay, which is reflected in its symbols. Most of the time, you’ll be seeing gold and red coins. However, you will also encounter brown and golden chests, octopuses, and jackpot icons.
The game has a fun, whimsical soundtrack that suits a fantasy-themed slot. We like that it sounds like it’s coming from a slight distance, simulating the feeling of being underwater. Occasionally, you’ll hear the Queen’s yawns or claps, along with all the sound effects that play when you win, or bonus symbols appear in the playing area.
Queen of Sirens Gameplay & Features
Evoplay’s game comes with a 3×3 grid and forgoes paylines and ways to win. Only bonus symbols can appear on the reels, whose prizes can only be collected while a feature is active.

Bonus Game
A combination of any three symbols on the central line will activate the Bonus Game. Triggering symbols remain in place while the feature is active, as is the case with any icons that appear while the Bonus Game is being played. You get three spins, with the number resetting whenever a new symbol lands. The feature continues until all nine positions on the grid are filled or you have used up all your free spins. The value of all icons is summed and paid out to the player.
Ultra Bonus Game
Ultra Bonus Game is an upgraded version of the feature mentioned above. The first spin of this bonus always activates the Luck of Aurora feature. You also have a higher chance of triggering it than in the regular Bonus game. It can activate randomly during normal gameplay.
Luck of Aurora
This feature randomly activates during Bonus Game or Ultra Bonus Game, firing up to 9 comets into random cells. Each hit cell receives a 2x multiplier. If one cell is hit multiple times, its multiplier increases by one for each comet hit. The multipliers remain until the Bonus Game or Ultra Bonus Game features are completed.
Bonus and Sticky Coins
Bonus coins are made of gold, while Sticky coins are gold with a red tint. Both come with an attached cash prize and are the primary way you’ll be scoring wins in the Queen of Sirens slot. Bonus coins can appear with rewards ranging from 1x to 4x. Meanwhile, Sticky coins are more valuable, with prizes from 5x to 9x. Sticky coins also have one more upside over standard bonus coins – they remain on the reels until the Bonus or Ultra Bonus Game activates.
Mystic Symbols
Mystic symbols are chests that open to reveal other icons. They can reveal any symbol except for Sticky Coins. They come in two tiers: wooden and golden chests. Golden chests are guaranteed to contain one of three fixed jackpots: Mini, Minor, or Major.
Octopus
Octopus symbols collect all values and jackpots from other bonus symbols when they land. This only happens once, meaning they won’t benefit from any new icons that appear after they show up on the reels.
Fixed Jackpots
There are four fixed jackpots in this Evoplay slot, which can only be won during the Bonus game.
- Mini – 10x
- Minor – 20x
- Major – 50x
- Grand – 500x
The mini, minor, and major jackpots are won when their corresponding coin shows up on the reels. Meanwhile, the grand jackpot is awarded when all positions on the 3×3 grid are filled with bonus symbols.
Bonus Buy
The game allows you to purchase direct access to its Bonus Game and Ultra Bonus Game. The former costs 30x your stake, while the latter will set you back 75x your total bet.
Queen of Sirens RTP and Payouts
Queen of Sirens has an RTP of 95.97%, which is better than most slots we test. It has high volatility, which may not be appealing to everyone. However, the 4,313x top prize may tempt some players into giving Evoplay’s release a chance.
