This bonus round can also be triggered during the Free Spins feature. These shells contain cash prizes that are added to your payline wins at the end of the bonus game. Here you will be provided with a series of shells and required to pick between 3 and 5 shells, depending on the number of Chests that triggered the bonus. The number of Chests that trigger the bonus will determine the number of picks you will get when you’re transported to the bottom of the sea. To trigger the Treasure Bonus in Mermaids Millions slot, 3 Treasure Chests must appear on an active line. More free spins can be activated by hitting 3 or more Mermaids again during the feature. You will also be awarded with scatter pays just before you get into the Free Spins feature, where your scatter wins will be multiplied by credits staked per line. In this bonus round, any win will be multiplied 3X. You only need 3 or more Mermaids to appear anywhere on the reels to trigger the 10 free spins allotment. In addition, 5 of King Neptune’s symbols appearing in a line will win you a top payout of 7,500 coins. King Neptune is the wild symbol, and he substitutes all other symbols on the reels apart from the Mermaids (scatters) and the Treasure Chests (bonus symbols). On the reels, you will come across symbols representing Mermaids, Treasure Chests, Pearl-bearing Oysters, King Neptune, Seahorses, and your high poker card symbols (like the ones used in video poker machines) wrapped in objects and sea creatures that relate to the theme. This 5-reel, 15-payline slot is set below sea level where whimsical creatures-half human, half fish-call home. Interestingly, Mermaids Millions features 2 bonus rounds, which is not only impressive for such a classic game, but for a Microgaming slot as well. The graphics are a bit dated, but it’s more or less a cult classic for Microgaming fans. Mermaids Millions the online slot game is a mermaid-themed slot (if you hadn’t guessed already) and one of the oldest slots by Microgaming, which explains the simple and straightforward play.
