Mermaids Millions in a Nutshell

Mermaids Millions is a Microgaming slot that was released back in 2008 and takes players on an aquatic journey to a fantasy world where mermaids exist. This is the perfect slot game for beginners as it has simple graphics and bonus features including a wild symbol, scatter symbol, free spins bonus round and a Treasure Bonus feature.
This is a mobile-friendly slot game with a high RTP of 96.56%. You can spin its reels today from as little as 5p up to a £375 per spin.

How to Play

How to Play Mermaids Millions in Four Simple Steps

Playing Mermaids Millions is very easy and here’s how you can get started playing step by step.

  1. Hit the Select Lines button and the + and – buttons to set the number of paylines
  2. Decide how much you are going to wager using the Select Coins + and – buttons to increase or decrease the coins
  3. You can use the autoplay function to choose the number of spins you want and your bet per spin, then let the game play automatically
  4. Once your bet is decided and placed, hit the blue SPIN button to send the reels tumbling


Gameplay, RTP and Variance

This is a five-reel, three-row slot game with 15 paylines. This is a game that players of all budgets can enjoy as bets per spin start from as little as 5p up to £375 per spin.

Mermaids Millions has an RTP of 96.56% which is quite high when compared to other slot games and means you are more likely to finish with a win. This is a low to medium variance slot game, which means it’s designed to offer fairly frequent, yet small payouts.

The merman is the highest value symbol on your reels and landing five on the reels will award you 7,500x your stake.

Bonus Features

There are three special features in the Mermaids Millions slot game including a wild symbol, free spins bonus round and a Treasure Bonus.

The wild symbol in Mermaids Millions is the merman and he will replace other symbols on your reels to form new winning combinations and award big cash prizes.

There is a free spins bonus round in Mermaids Millions and this is triggered by landing three or more of the mermaid scatter symbols. Players will be awarded ten free spins and all wins will have a 3x multiplier applied. If you land more scatter symbols during this round, you can retrigger it.

Players can trigger the Treasure Bonus feature by landing three or more of the treasure chest bonus symbols. Players will be transported to another location under the sea and presented with a picking game. Choose three to unveil cash prizes. This bonus feature can also be triggered within the free spins bonus round.


Playing Mermaids Millions on Mobile

Mermaids Millions is a mobile-friendly slot game that can be played on the go on iOS and Android devices. The controls and graphics will adapt perfectly to fit both mobile and tablet screens, so there’s no need to sacrifice on the quality of the game.


Design, sound and graphics

Mermaids Millions was released way back in 2008 and so the graphics aren’t the high-quality that you may be used to from newer games on the market. They are quite outdated and simple, but as long as you know this before starting, you won’t be disappointed! The game transports players under the sea to an aquatic world where mermaids live. The background of the reels is a simple dark blue and on the reels, you will find lots of high-value symbols that relate to the mermaid theme such as a mermaid, a merman, sparkling gems, a pearl in an oyster and a treasure chest. The low-value symbols are your standard playing card symbols with lots of fishy creatures attached to them such as lobsters, starfish and octopi. The soundtrack in this game is also very simple and you can hear the faint sound of the waves in the background, but it doesn’t add much overall to the game.

Our Verdict

What We Think

If you are looking for a simple and easy slot game to play then Mermaids Millions is a great choice. This slot game is over a decade old and so while it has a nice mermaid and aquatic theme, the graphics are of course, not as sharp as some of the newer slots out there. This is the perfect game for beginners to try as it keeps things easy to understand with just a wild symbol, free spins bonus round and the extra Treasure Bonus up for grabs. There are lots of cash prize treasures to be found under the sea in Mermaids Millions and you can spin its reels to grab your share. Use our carefully curated list of casinos to compare, sign up and play today.
