Gold of Sirens Slot Overview
Sirens guard a hoard of sunken gold, and there are two separate ways to get at it. The grid underneath is ordinary, 5x3 with 20 fixed lines paying left to right, but Evoplay bolted a free spins round and a hold and win jackpot game onto it, and the two play nothing alike.
The free spins are the reason to load this one. On every spin of the feature, one low-paying symbol type gets picked at random and every copy of it on the grid turns Wild. Not one instance. All of them, and a fresh pick on the next spin.
High volatility, and nothing to buy your way in with. The features arrive when they arrive.
Theme & Design
Two cracked stone mermaids stand guard either side of the reels, tails curled around broken Greek columns, while shafts of surface light cut down through the water behind them. Small fish drift across the top of the frame. Red and pink coral crowds the bottom. It is all one deep saturated blue, and the reel tiles sit dark enough that the symbols pop cleanly out of it.
The four sirens are the best art in the game: silver, turquoise, purple and auburn hair, gold collars, shells and starfish worked into the braids. They all have their eyes closed and the same drowsy half-smile though, so in practice you sort them by hair colour and nothing else. The low pays are jellyfish in pink, amber, blue and green, drawn with far more personality than the card royals a sea-themed slot would normally get away with. The Scatter is a gilded picture frame holding a blue-skinned siren coiled around a drowning sailor, a nicer piece of storytelling than the feature it triggers really needs. Wild is a gold trident crown set with blue stones. Jackpot symbols are heavy gold coins stamped with an octopus, their value printed straight across the face.
Above the grid a temple pediment carries the three jackpot bars: MAJOR in blue, EPIC in red, MINOR in green. Poseidon himself gets a full portrait before the first spin, crowned and scowling with a glowing jellyfish balanced on one palm, then never appears on the reels at all.

Features & How They Work
Wilds That Outpay the Sirens
The Wild is a gold trident crown, and it substitutes every symbol except the Scatter and the Jackpot coin. It lands on any reel, in the base game and in free spins alike. Less usual is that it pays in its own right, and pays better than anything else on the reels: 2x, 5x and 50x the line bet for three, four and five. The best siren stops at 40x. Every payout in the game runs off the line bet rather than the total stake, which is why the low-pay numbers look so slight written down.
Free Spins and the Wild Replace
Three, four or five Scatters anywhere on the reels award 8, 10 or 12 free spins, played at the stake that triggered them. Each Scatter landing during the round adds one more spin, so there is no three-symbol retrigger to sit and wait for.
The round itself works differently from almost anything else in this format. On each free spin the game picks one of the low-paying jellyfish types at random from those that landed, and every single copy of that symbol on the grid turns Wild for that spin. Six blue jellyfish on the board become six Wilds. The spin resolves, the pick is thrown away, and the next spin chooses again from scratch.
It is smart design because it recycles the game's dead weight. Low pays are the symbols you normally groan at, and here they are the only ones eligible for conversion, which flips a cluttered, worthless-looking board into the best-paying symbol in the game. It cuts both ways, of course. The pick is random, so a spin where the chosen type landed twice does nothing at all.
The Jackpot Game
Six or more Jackpot coins landing on one spin start a hold and win round with three respins on the clock. Locked coins stay put until the end, and any new coin resets the respin count back to three. Nothing else appears on the reels while it runs, so every respin either brings a coin or takes you a step closer to the finish.
The round ends when the respins run out or all 15 positions are filled. Every locked coin then pays its own value, and the total is added to whatever the triggering spin won. Regular coins carry a random 1x to 10x the bet. MINOR coins pay 20x, MAJOR coins pay 50x, and filling all 15 positions adds the EPIC at 3,000x on top of everything already locked.
Reading the Jackpot Meter
The three bars above the reels read 500 for MAJOR, 30000 for EPIC and 200 for MINOR, and those are coin-value readouts, not bet multipliers. The awards themselves are 50x, 3,000x and 20x the bet. Take 30000 off that bar as a multiplier and you land on a max win ten times bigger than the game can pay; the ceiling is 6,119x the total bet. None of the three are progressive pots either, despite the presentation. They are fixed multipliers that happen to be displayed on a meter.

How Gold of Sirens Plays
The base game is thin, and it is meant to be. A three-of-a-kind jellyfish line pays 0.1x to 0.5x the line bet, which on a small stake is money you barely notice arriving. Sirens land often enough to keep the balance drifting sideways. Everything this game has to give sits in the two bonuses, and the flat stretches are the toll for getting there.
Free spins carry the better tension, because the pressure resets on every spin. Eight spins is not many, and each one is its own little draw: watch which jellyfish crowd the board, then wait to see whether the game picks that one. When it does, the grid lights up in a way a normal wild-heavy round never quite manages. When it picks the type that landed once in the corner, a spin is gone. That swing, repeated eight to twelve times running, is the most interesting thing about playing it.
The jackpot game has the opposite problem. It arrives with no warning at all: no collection meter filling, no near-miss on five coins, nothing building. Six coins land or they do not (and yes, everyone has played a hold and win by now, so the round itself holds no surprises). Once it starts, the reset-to-three counter does its job, and a board sitting at eleven coins with one respin left is properly tense. Getting to fifteen is another matter, and you will probably never see it.
Pros & Cons
Pros
- 96.18% RTP, above where most of the Evoplay catalogue lands
- The Wild Replace makes a free spins round that looks like nobody else's
- Two independent bonus routes give the game more shape than most 20-line slots
- Coin values print on the coin faces, so a hold and win round stays readable as it builds
Cons
- 6,119x is only moderate for a high-volatility release, and the EPIC's 3,000x puts roughly half the ceiling behind a perfect 15 of 15 board
- Base game is flat, with low-pay lines too small to register
- The Wild Replace pick is random, so a fair share of free spins convert a symbol that barely landed
- The jackpot game starts cold, with no build-up or near-miss to give it any anticipation
Is Gold of Sirens Worth Playing?
Evoplay put a proper idea into the free spins here, and that lifts Gold of Sirens above the studio's long run of good-looking, hollow releases. The 96.18% return helps, sitting well above where their catalogue usually settles. The hold and win next to it is competent and completely familiar, which is fine; it gives the game a second way to pay without pretending to be new.
Where it falls short is ambition at the top end. A 6,119x ceiling from a high-volatility 2021 slot is unremarkable, and the EPIC sitting behind a full 15-coin board makes the biggest number on the meter closer to a lottery ticket than a target. What holds up best is the art. Five years on, the sirens and that sunken temple still look better than plenty of what shipped alongside them.
