Mermaid Royale Symbols and Paytable Explained

The reels of Mermaid Royale are packed with recognizable sea-themed icons that add more depth to the underwater experience.

 

Categories of Symbols:

  • High-Paying Symbols: Treasure chests, gold coins, and the majestic mermaid herself
  • Mid-Paying Symbols: Crown, pearls, and royal artifacts
  • Low-Paying Symbols: Classic card symbols (A, K, Q, J, 10) stylized in an oceanic theme

 

The Bonus Game Special Mechanic

Among the most striking features of Mermaid Royale is its expanding wilds and mega symbols, which are 3×3. When such a wild or mega symbol lands on the reel, it greatly increases your chance of getting larger payouts. Free spins can also be triggered using scatter symbols, that bring huge potential.

 

The Wild Symbol Substitution

The wild is one of the most powerful features in the game. It substitutes any other symbol (except for scatters) to form winning combinations. And that’s not all: this wild can expand to cover an entire reel, dramatically increasing your chances of hitting big wins!

 

Mermaid Royale Special Features

Each slot has its own mechanics, and Mermaid Royale is not an exception:

TurboSpins Explained

Does Mermaid Royale Feature Bonus Buy?

Mermaid Royale does not have a Bonus Buy feature. Free spins and special mechanics are only triggered by organic gameplay.

 

RTP and Volatility Explained

  • RTP (Return to Player): 96.25% – This is the average return that players can expect over an extended period of play.
  • Volatility: Not officially stated, but based on gameplay, it leans towards medium-to-high volatility, meaning big wins can come, but they may take some time.
