Mermaid Millions

Mermaids Millions is an early Microgaming slot that has recently made the successful transition to mobile.

Its charming cartoon depictions of mermaids, Neptune, and sea creatures are extremely colourful, and the slot's creators have also injected some humour by adding sunglasses to the seahorse and a cute lobster to the Ace symbol. It might not look like the kind of slot that comes with many bonus features due to its age, but beneath the calm surface, Mermaids Millions hides several nice surprises. For example, the Mermaid scatter can help you score extra cash with her triggerable free spins bonus.

The Neptune wild can conjure up impressive prizes either on its own or as a substituting symbol in a winning combination, and the Treasure Bonus lets you pick from a selection of sunken chests to reveal additional wins. Plus, the game can accommodate all kinds of budgets with its broad betting range of 5p to £375 per spin.

More about the Software Provider

Microgaming started out in 1994, and has been making casino software, slots, table games, card games, and live dealer games in the years since. Microgaming's oriental-themed online slots have proved particularly popular among players and they include titles like Asian Beauty, Win Sum Dim Sum, and Huangdi – The Yellow Emperor. Many European casinos run on Microgaming software, and the company even has its own online poker network known as MPN.

Appearance and Sound Effects

Have you ever wondered what lurks beneath the surface of the world's oceans? Well, thanks to Mermaids Millions, there's no need to undertake a PADI diving course to find out. In Microgaming's magical underwater world, you will encounter the Roman god of the sea, Neptune, as well as a beautiful mermaid, treasure chests, jewellery boxes, seahorses, oysters containing valuable pearls, and playing card symbols adorned with octopuses, starfish, pearl necklaces, tridents, and lobsters.

To make the environment even more enchanting and realistic, the sound effects include the noises of waves, mermaids laughing, and air bubbles escaping to the surface.

Bonuses and Special Features

There are many winning opportunities on offer in the Mermaids Millions slot, and the wild symbol (which is Neptune) can significantly boost your chances of gaining prizes. The wild symbol substitutes for all symbols except the mermaid and the treasure chest.

The mermaid gives you ten free spins whenever she lands three, four or five times on the reels, and as well as allowing you to retrigger the bonus with extra scatters, she swells the value of all prizes gained by three times.

Finally, Mermaids Millions has a Treasure Bonus which is triggered when three, four or five Treasure Chest bonus symbols appear anywhere on the reels. It's a Click-Me Bonus where you need to choose from a line-up of barrels, oyster shells, and treasure chests to claim instant coin wins. The more scatters that trigger the bonus, the more picks you get.


Mermaids Millions uses five reels, three rows of symbols, and fifteen non-fixed paylines, and has a high RTP (Return to Player Rate) of 96.56%.

Mobile Compatibility

The game is designed to work with desktops, laptops, mobile phones, and tablets, and includes mobile-friendly game controls when played on mobile devices.

Our Verdict

Mermaids Millions is one of Microgaming's earliest slots, and although its graphics seem a little retro when compared to those featured in more recent slot releases like Tarzan and Dragonz, it's a great little game with a re-triggerable free spins bonus and a fun Treasure Bonus where you can dive to the bottom of the sea and open sunken treasure chests to gain prizes.
