Pragmatic Play invites players to plunge into an enchanting underwater world in Mermaid's Treasure Trove, a visually rich slot built on a 7x7 cluster pays grid. The game blends cascading wins, roaming wild multipliers, and a highly volatile math model to deliver thrilling spins beneath the sea. With a max win of 10,000x your bet and a top RTP of 96.54%, this slot offers both excitement and depth. The aquatic theme is brought to life with shimmering symbols like treasure chests, crowns, and mystical harps, while the mermaid herself floats beside the reels, adding charm to every spin. Whether you're chasing free spins or exploring the bonus buy options, Mermaid's Treasure Trove is a deep-sea adventure worth exploring.
Mermaid's Treasure Trove plays out on a shimmering 7x7 grid using a cluster pays system. Wins form when 5 or more matching symbols connect horizontally or vertically. Winning clusters explode, triggering cascading tumbles that can chain into multiple wins. The game’s high volatility and dynamic wild multipliers keep each spin unpredictable and rewarding. Symbols range from shells and starfish to treasure chests and crowns, with payouts scaling based on cluster size.
One of the standout features is the roaming multiplier wild. After a win clears, a wild drops into the empty space with a starting value of x1. Each time it contributes to a win, its multiplier increases by +1 and shifts to a new position. If multiple wilds connect, they merge into a single wild, combining their values. Regular symbols can also carry multipliers (x5–x100), which are added to the wild if part of the same win. These wilds persist through tumbles, creating extended win chains and explosive payouts.
Landing 3 to 7 scatter symbols triggers 10 to 18 free spins. During the feature, multiplier wilds remain on the grid until the round ends, and any wilds present on the triggering spin carry over. Additional scatters during the bonus round award +1 extra spin. This sticky wild mechanic adds strategic depth and increases the potential for massive cluster wins.
In both the base and bonus game, regular pay symbols can land with attached multipliers ranging from x5 to x100. If these symbols form part of a win with a wild, their values are added to the wild’s multiplier. If no wild is present, a new one is created with the combined value. This feature adds surprise bursts of value and keeps gameplay fresh.
Players can activate the ante bet to increase their chances of triggering free spins. This comes at a 50% higher stake but boosts scatter frequency. It’s a strategic option for those chasing bonus rounds more aggressively, though it may not suit budget-conscious players.
