Queen of the Sea by GMW places five reels and four rows in an underwater mermaid kingdom of sea creatures and treasure. Ordinary spins use up to 50 paylines, while the Queen collects designated symbols for a feature that can reveal Match, Hold & Spin or Free Games. The action shifts from reading line combinations to choosing shells, building a prize board or following persistent Wilds.
Quick take: Locked treasure rows give this underwater Hold & Spin feature something more to chase than empty spaces.
Theme and Gameplay
The sea creatures and treasure fit the game's two main kinds of result: matching symbols across the reels and collecting prizes during features. On ordinary spins, winning combinations run consecutively from left to right. Separate line wins are added, with only the highest award paid on each active line.
Wilds substitute for ordinary symbols, but not for the Treasure Chest Scatter. Those chests appear on reels two, three and four and pay regardless of their line positions. A chest award can therefore sit alongside a line win, making it useful to read the two results separately.
Slot Features
Hold & Spin begins with six prize symbols, three respins and two additional locked rows. Empty positions respin, and each new prize symbol restores the counter to three. The board keeps developing until the respins run out or every feature position is full.
The locked rows add a second concern beyond filling gaps. Prizes can land there, but they only become awarded prizes if an Orb unlocks their row. An Orb can open one or both rows. Trident can also add a second prize symbol to an occupied position, with the added value equal to or greater than the original and a limit of two prize symbols per position.
Match gives the player a different task: choose from twelve shells until three identical prizes appear, then receive that prize. Free Games awards ten, fifteen or twenty spins. Symbols converted to Wild remain Wild for the rest of the free games, so a conversion can keep helping after the spin on which it happens.
Feature focus: Watch where a Hold & Spin prize lands: a value in a locked row still needs an Orb before it joins the awarded treasure.
RTP and Win Potential
Queen of the Sea lists 95.80% RTP and high volatility, suggesting uneven returns rather than a steady stream of similar awards. Hold & Spin prizes are multiplied by the triggering bet. Two linked progressive jackpot levels add further prize targets across the features; their presence does not make a jackpot a routine outcome.
My Thoughts On This Slot
The locked rows give the treasure theme a practical role. A visible prize can remain out of reach, which makes an Orb meaningful even when the board already looks well stocked. Trident provides another useful distinction: an occupied position can still improve, so filling space is only part of the feature's progress.
That extra bookkeeping may feel busy to someone who wants every displayed coin to count immediately. Queen of the Sea is better suited to someone who enjoys following a changing prize board, with shell picking and persistent Wilds providing different rhythms between treasure hunts.
Final Take: Queen of the Sea makes its treasure chase interesting through the difference between prizes in view and prizes actually unlocked.
