Rules and Gameplay

Lucky Mermaid slot, powered by Swintt, immerses players in an underwater adventure across a 5×3 reel layout with 10 fixed paylines. To start the journey, players adjust their bets using the Bet +/- buttons, then either spin manually or use Auto Spin for continuous play. A distinctive Gamble feature becomes available after wins, offering a chance to double or quadruple the reward by guessing the color or suit of a card, respectively. Gameplay is straightforward, yet enriched with deep-sea mysteries waiting to be uncovered.

Bonus Features

Lucky Mermaid boasts several enticing bonus features designed to enhance the underwater escapade:

  • Wild Symbol: The blonde Mermaid acts as the Wild, substituting for other symbols except the MULTI letters to form winning combinations.
  • Pearl Feature: Collecting M, U, L, T, and I letters triggers this feature, replacing collected symbols with Wilds and initiating a respin round with sticky Pearls that can multiply wins up to x150.
  • Gamble Feature: Available after any win, offering players a chance to double or quadruple their winnings by correctly guessing the color or suit of a card.

These features, especially the innovative Pearl Feature, provide a dynamic and potentially lucrative gaming experience.


The enchanting world of Lucky Mermaid is filled with a variety of symbols, each adding to the underwater narrative:

  • High-value Symbols: Mermaids, Turtles, Blue Fish, and Red Fish, with the Mermaid being the most lucrative.
  • Low-value Symbols: Classic card royals (A, K, Q, J), representing smaller wins.
  • Special Symbols: MULTI letter symbols for triggering the Pearl Feature and the Mermaid Wilds.

These symbols, particularly the thematic high-value ones, are key to unlocking the game’s treasures.


Lucky Mermaid offers a range of payouts, with its low to medium volatility and RTP rates varying from 85.25% to 95.05%. The maximum win potential is capped at x3026 the bet, offering significant upside for players. Detailed payouts for symbol combinations are as follows:

Symbol 3x Payout 4x Payout 5x Payout
Mermaid (Wild) $20 $200 $1000
Red Fish $8 $40 $200
Blue Fish $4 $20 $50
Turtle $3 $15 $40

This table illustrates the game’s potential for rewarding wins, especially through high-value symbols and features.


Lucky Mermaid is designed with 10 fixed paylines, enabling various winning combinations. Players must match symbols from left to right across the reels on any of these paylines to secure a win. The fixed nature of these paylines means that all 10 are active during each spin, maximizing players’ chances to land winning combinations and engage with the game’s bonus features.
