Mermaid's Pearl is an enchanting 5-reel underwater slot that plunges players into the depths of the ocean to discover hidden treasures alongside mystical mermaids. This captivating slot machine offers flexible gameplay with 5, 10, or 20 paylines and features an immersive aquatic theme filled with sunken riches waiting to be claimed.

The game's standout feature is its lucrative Bonus games system where landing 3, 4, or 5 scattered TREASURE CHEST symbols awards 40, 50, or 60 free bonus spins respectively. What makes this feature even more rewarding is that additional TREASURE CHESTS during the bonus rounds can retrigger the feature, awarding the same number of extra bonus games.

The beautiful MERMAID symbol serves as the wild, substituting for all symbols except the TREASURE CHEST scatter, and delivers 2x multiplier wins when completing winning combinations. All standard wins pay from left to right, while the TREASURE CHEST scatter pays anywhere on the reels, making every spin an opportunity for underwater riches at TwentyOne.
