Mermaids Millions

They say that the oldies are always the goodies, and in the case of the Mermaids Millions online slot by Microgaming, that’s never been truer.

Over the years, Microgaming has created many iconic online slots that prove just as popular with online casino and bingo fans today. Aside from Mermaids Millions, there’s Avalon, Avalon II, Thunderstruck and, of course, everyone’s favourite progressive jackpot slot, Mega Moolah.

Due to its age, the graphics that are used in Mermaids Millions aren’t quite as sharp or detailed as some of Microgaming’s more modern video slots such as Game of Thrones 243 Ways. But, its charming theme has helped it to stand the test of time.

The star of the game is a mermaid who lives with her friends underneath the ocean waves. And, in her underwater hideaway, she’s been collecting precious pearls and gold coins over the centuries which you have the chance to swim away with when you play this online slot with a stake of 5p to £375.

As well as boasting a particularly broad betting range, Mermaids Millions delights online slot fans with its multiple special features. There are wild substitutions which can help you win more prizes more often, a free games bonus that multiplies all wins by three and can also be re-triggered with extra scatter symbols, and a Treasure Bonus that lets you explore the ocean floor, picking up cash prizes.


Mermaids Millions uses a pale blue background to represent the warm, clear waters in which the mermaid lives. The fifteen paylines are pointed out via coloured indicators to each side of the reel set, the latter of which includes five reels and three rows of symbols.

All wins pay from left to right except for scatters which pay any way.

There are eleven different symbols that can be used to create winning combinations, and in order of most valuable to least valuable, they are Neptune (the god of the ocean), the Treasure Chest, the Jewellery Box, the Oyster Shell, the Mermaid, the Seahorse, the A, the K, the Q, the J, and the 10.

What’s rather lovely is that many of the symbols are quite comical. For example, the seahorse is wearing black sunglasses while a nervous crab hides behind the A.

The game controls are very easy to spot. If you want to find how much the various symbols are worth, you simply click the “View Payout” link just beneath the game logo, and to return to the game, you click on the “Back to Game” link. To view the full rules, click on the red “Help” button.

You can adjust the number of played paylines at the bottom of the screen where you’ll also find plus and minus buttons that let you set the stake-per-line to 0.01, 0.02, 0.05, 0.10, 0.20, 0.25, 0.50, 1.00, 2.00 or 5.00. You can also choose to play with 1, 2, 3, 4 or 5 coins per spin.

Wild Symbol

In the Mermaids Millions online slot, the wild symbol is represented by the god of the ocean who’s Neptune if you’re a fan of Roman mythology or Poseidon if you favour the Greek deities.

The cheery white-haired god with a big fluffy beard and seashells in his hair pays out more prize money than any other symbol in the game, giving you a mammoth 7,500 times your bet for five-of-a-kind. Plus, he can replace all symbols except the scatter and Treasure Bonus symbol to aid you in forming winning combinations.

Scatter Symbol

The Mermaids Millions online slot uses both a scatter symbol and a bonus symbol.

The pretty blonde-haired mermaid is the scatter symbol, and she awards scatter wins of up to 400 times your stake. Plus, she can grant you access to the Free Games Feature.

The treasure chest is the bonus symbol, and it awards instant cash prizes whenever it appears in three or more locations on an active payline. And, it can also unlock the Treasure Bonus.

Bonus Round

Because Mermaids Millions uses both a scatter and a bonus symbol, there are two bonus games to enjoy.

You need three, four or five Mermaid scatter symbols to appear anywhere in view to earn ten free spins, and if, during the Free Games Feature, another three, four or five scatters land anywhere on the reels, the feature is retriggered. You initially receive ten free spins, and any winning combinations that are created are tripled in value.

To unlock the Treasure Bonus, you need three, four or five Treasure Chest bonus symbols to appear on an active payline. In the Treasure Bonus, you’re taken to a new screen which features the seabed, and you must choose various objects that lie on the ocean floor to reveal random bonus win amounts. It’s possible to trigger the Treasure Bonus in both the base game and the Free Games Feature.
