About the Manufacturer

For many online casino players, Microgaming is the best mobile slots producer in the world. Over the years, its games have evolved from basic graphics and minimal special features to innovative HD slots with complex gameplay and multiple bonus features.

The oldest Microgaming mobile slots include Mermaids Millions, Avalon, and Thunderstruck while its newest releases (at the time of writing) consist of Life of Riches, Huangdi - The Yellow Emperor, and Candy Dreams.

Appearance and Sound Effects

When compared to more recent Microgaming mobile slots games like Candy Dreams, Mermaids Millions looks remarkably retro, but then again, that's part of its charm and one of the reasons why the game has stood the test of time.

There's a basic blue background which is meant to represent the ocean, and on each side of the reels, there are numbers marking each of the fifteen paylines.

The paytable symbols that appear on the reels as you spin them include a pretty blonde mermaid, Neptune (the Roman god of the ocean), a treasure chest, a jewellery box filled with gems, an oyster shell bearing a sparkling pearl, a seahorse (which is oddly wearing sunglasses), and five playing card symbols (10, J, Q, K, and A) which are entwined by starfish, strings of pearls, lobsters, and octopuses.

The sound effects that are used in Mermaids Millions are relaxing noises of splashing water and air bubbles.

Special Features

Neptune acts as the wild symbol in Mermaids Millions, and he can help you create wins by substituting for all symbols except the mermaid and the treasure chest.

The mermaid is the scatter, and she gives you ten free games with a 3x multiplier whenever she appears in three or more reel positions on a single spin. There's also a chance of re-triggering the feature if she crops up again three more times.

The main bonus game is activated with three or more treasure chest symbols, and it requires you to pick from a selection of sunken barrels, chests, and oyster shells to reveal instant cash prizes.


All wins pay from left-to-right, apart from scatters which pay any way.

Playing on Mobile Devices

The game is fully-optimised for mobile play, and includes mobile-friendly game controls for spinning the reels and placing bets.

HMOur Opinion:

The wonderfully retro graphics, high RTP (Theoretical Return to Player Rate) of 96% to 97%, free spins feature, and the bonus game which sends you hunting for treasure on the ocean floor make Mermaids Millions a firm favourite among mobile slots fans.
