Play Today

14 years into Microgaming running, publishing new online slots and learning what players like came this slot. They released Mermaid’s Millions back in 2008 which has a play board consisting of 5 reels and 3 rows. This underwater mermaid theme plays with a total of 15 paylines, which is less than we have come to expect with inventions like megaways, but comparatively to slots around the time this was fairly standard.

Mermaid’s Millions plays with a low to medium volatility and an RTP of 95.56%. With this have a reasonable betting range, that starts at min bets of £0.15 and goes up to a max bet of £75, this does mean that the high rollers will probably be excluded from getting involved, but there is still good motivation to spin the reels with a max payout 37,500 coins on a single spin!

Mermaids Millions Theme and Graphics

When we open Mermaid’s Millions we are placed at the bottom of the ocean, staring at the sky. We can see swirling schools of fish in the shadowy depths.

The playing board has been kept simple, with a delicate and intricate blue border on either side, somewhat reminiscent of Victoria décor. 

Looking at the symbols and we have incredibly playful drawings of each character. Poseidon has a huge grin across his face with a colourful crown. There is a seahorse chilling in the sun with a pair of sunglasses on as well as plenty of other sea life creeping into the card deck value symbols.

If that wasn’t enough fun, when we manage to get through to the bonus round, we get to inspect the seafloor, where we can see all of the treasures fallen from passing ships.

Mermaids Millions Free Spins & Bonus Games

Being an older slot, we shouldn’t expect to see a huge plethora of bonus features to be integrated into the game, that being said, we do have one completely separate game to play. Let's break down what we have on offer.


The wild symbol in Mermaid’s Millions is a symbol of Poseidon who has a crown of barnacles and seashells. The wild symbol will substitute for every symbol except for the treasure bonus and mermaid scatter symbols.

Free Spins

To gain access to the free spins bonus round, we have to land 3 or more of the mermaid scatter symbols. When we manage this, we will be awarded 10 free spins. This slot also allows to re-trigger during the bonus game!

During this bonus round all our wins will be multiplied by 3!

Treasure Bonus

Mermaid’s Millions comes with a bonus game which is activated by landing 3 or more Treasure Bonus Symbols on an active payline and can be triggered in both the free spins bonus game and the base game. Players are presented with a collection of sunken barrels and treasure chests that lay on the bottom of the ocean floor.

We have to click on the items to reveal their cash prize. The more Treasure Bonus Symbols that activate the bonus game will reward us with varying amounts of picks.

  • 4 Treasure Bonus Symbols Rewards 4 Picks
  • 5 Treasure Bonus Symbols Rewards 5 Picks

Last Thoughts on this Online Slot

Mermaid’s Millions keeps things pretty simple, the visual of this slot game is full of fun, all of the symbols have tongue in cheek feel to them, aside from the mermaid herself who is simply a beauty. All of this is accompanied by the bubbling of water running past our ears.

From our experience older slots tend to lack bonus features and games, so it was a great surprise when we found the treasure bonus feature, whilst it is fairly basic in comparison to some of the newer bonus games, it added a refreshing mix of screens and ways to win!

Microgaming has enough experience to make top tier slots, and they have done just that with Mermaid’s Millions, although it was released back in 2008 it still keeps pace with most of the current slot games out there and is definitely worth a few spins! We rate Mermaid’s Millions a 6/10 slot!

Mega Moolah Slot is another amazing game available at Bonanza Slots!
