Mermaid Royale Slot Review

August 30th, 2023



It is not often that RTG pampers its players with a game focused on the marine realm, so the release of Mermaid Royale by RealTime Gaming felt like a real treat. As the name implies, in your hunt for the treasures of the under deep, you’ll be aided by the charming fish-tailed ladies.

Besides medium volatility, the slot game is also characterized by its 5x3 (+1) gaming board, which we shall explore in detail below, and 25 fixed paylines. Unfortunately, no jackpots are to be found in Mermaid Royale, but RTG makes up for it by ramping the top award up to 50,000 times the bet.

Graphics & Design

We couldn’t help but notice the game’s characters look eerily similar to Divas of Darkness from another recent RTG release, but the designers receive props for drawing them from scratch instead of doing a cheap re-skin. Overall, the title is eye-catching, and the decorations match the theme well.

Core Gameplay

The slot machine basics feature a pretty tame approach to Wilds - they don’t do much save for the usual substitution and can sometimes expand to cover the whole board. The Scatter rules, however, were thoroughly reworked - the most lucrative extras are activated by stacking Regular, Special, and Treasure Chest scatters.

In-Game Extras

It is how far one can go if they get enough scatters of a certain type on the board:

Regular Scatter: Gives +3 Free Games but needs to be accompanied by two more Scatters to trigger the mode.

Special Scatter: Only appears on the Bonus Row and gives +4 Free Games. The Specials stack on top of the Regulars - get one of the former and two of the latter, and the Free Game mode will launch.

Treasure Scatter: Only appears on the Bonus Row. Three of these are needed to grant 3 re-spins with the Oversized bonus symbols.

Random Booster. Appears only while the Free Game mode is active. Triggered by either three Wilds on reel 5, a dynamic x2 multiplier, or the Oversized symbols.

Bottom Line

We have every reason to finish this Mermaid Royale slot review on a high note - it’s a game that manages to squeeze the most out of legacy mechanics and keeps things entertaining, even if you’re a seasoned player.

RealTime Gaming must be credited for cleaning up the somewhat cluttered mechanics of the previous games - Mermaid Royale is a much more dynamic and, thus, more enjoyable experience.
