Mermaids Millions Symbols
On the reels, styled A, K, Q, J, and 10 card faces are the low-paying symbols, while the seahorse, clam and pot gems are the high-paying symbols. The bearded figure of Neptune represents the Wild, and the Scatter is the mermaid figure. An additional Treasure Chest symbol is available during the base game and bonus rounds.
Mermaids Millions Bonus Feature
Several bonus features will boost your chances of landing winning combinations while playing this five-reel slot. The Wild will substitute for all other standard symbols while the Scatter triggers the Free Spins round.
Apart from the two special symbols, a Treasure bonus feature is triggered by landing three, four or five chests on the reels. This will take you deeper into the seabed, where you will have a corresponding number of picks to unlock random prizes.
