Mermaids Millions from Microgaming: Slot Review - an underwater adventure
As you can imagine from the game title, this slot is underwater based and it focuses on a beautiful blonde mermaid who swims the ocean depths with her father, a red lobster and a hip seahorse for company!
I heard about this game for quite some time and how it had achieved cult status among slot players so I was quite eager to give it a go and see what the fuss was all about.
It is 5 reel slot game with 15 paylines and features not just one but two bonus rounds to enjoy.

Top Casinos for Mermaids Millions
Special Features
The first feature I noticed was the Mermaid King Wild symbol. The Mermaid king is Neptune of course and if you land 5 of these symbols on an active payline then you will win a hefty payout worth 7,500 coins!
The Mermaid is the Scatter symbol in this game and this symbol can create scatter wins which are all multiplied by the total bet wagered. If you land 3 or more of these symbols across the reels then you will trigger the Free Spins feature. In this game, you will be awarded 10 free spins and all wins are tripled! Free spins can also be retriggered. Definite catch of the day material there!
The last feature is the Treasure Chest Bonus feature. If you land 3 or more Treasure Chest Bonus symbols then you will trigger it. You will be taken to a screen of a seabed filled with various objects like chests and barrels and you get to choose 3 of them which will each reveal a cash prize. The cool thing about this feature is that it can also be triggered during the Free Spins feature. A minor gripe about the feature is that the font looks a tad out of place when you open the chests to reveal prizes.

Theme, Graphics and Sound
While the graphics look a bit dated in comparison to other slots, the game has a certain charm to it. The symbols are bright and sparkly and swoosh up and down the reels nicely.
There is a cartoon-like quality to the characters in this game and it is quite rare to see a seahorse wearing sunglasses these days! Another nice touch is that various sea objects adorn the lower paying symbols such as Tridents and pearls on the K and Q symbols.
The music as you would expect is of the nautical variety, so lots of waves and billowing bubble sounds are used to create an oceanic atmosphere.
