Slot Review: Mermaid Royale – Game Specifics

RTG’s 21 December 2022 release is an online slot called Mermaid Royale.

The supplier labels this game as having a “Underwater” theme due to its prevalence of mermaid imagery and other aquatic accents.

The above online casino is offering new players 40 free spins when they sign up and use the coupon code MERMAIDROYALE.

Style of Slots

The gameboard for the Mermaid Royale slot machine is a little unusual from the typical 5×3 layout, including 5 reels, 3 rows, and 25 fixed paylines, plus a bonus 3×1 reel on top.

The game has a medium volatility and an RTP of around 96.00%.

If you’re searching for a slot machine with a low wagering requirement, this one has a minimum bet each spin of just $0.25 and a maximum stake per spin of $25.00.

The interface is typical of RTG slots in that it contains a spin button, a max bet button, an autoplay button, a plus and minus sign for adjusting the quantity of your wager, a main menu button, and a paytable button.

You may turn off the slot machine’s music and/or sounds from the main menu.

Most slots developed by RTG also allow you to spin the reels by pressing the space bar on your keyboard.

In general, the slot machine looks fantastic, with bright, well-polished symbols, an additional row above reels 2, 3, and 4, and a booster bar over on the left.

The booster bar represents a possible bonus, such as two times as many large wilds, two times as many wins, or a complete stack of wilds.

Slot Functions

Wilds can expand when they replace other symbols in the game, including the scatter and treasure symbols, but not the retrigger scatter or the enormous symbol. When a bonus reel appears, any wild symbols on it will grow to fill the entire reel.

In this scenario, the wild started on reel 4 and covered the entire reel, leading to a 40.00 dollar payout.

Spins at No Cost: During the main game, free spins are triggered by the appearance of three normal scatters or a combination of regular and special scatters. The standard scatters grant an additional 3 free games for every one on the board, while the bonus 3×1 scatters grant an additional 4 free games with a Random Booster if they appear there.

Reels 2, 3, and 4 become an Oversized Symbol Reel, spinning with Reels 1 and 5 during the bonus game. Each retrigger scatter that falls on the bonus row triggers an additional free spin. There were no major payouts throughout our 10 free spins, despite the fact that we hit a variety of full-size symbols in the middle. In fact, we observed payouts of $40.00 and $65.00 on a $25.00 per spin wager.

Respins: In the main game, the player receives three respins for landing three treasure chests or a combination of treasure chests and wilds. During this bonus round, reels 2, 3, and 4 expand to a 3×3 colossal symbol and spin alongside reels 1 and 5.

Our 25.00 per-spin wager resulted in a 1,755.00 jackpot when we hit five red mermaids in a row.

Free spins with a random multiplier are triggered if the special scatters appear in the triggering combination. The multipliers give the boosters a choice between betting on a complete stack of wilds on reel 5 or on two times as many wilds occurring on the reel with the bigger symbols. There is a cap of three random boosters each game, so if a retrigger happens, the player will not get any further random boosters.

As we were unable to even achieve 2x payoff, the “double winnings booster” we received when we activated the free spins was of limited use.


The many elements in the online slot game Mermaid Royale often activate to keep the player amused.

RTG never fails to impress with its excellent visuals and design.
