Mermaids Millions Reels, Paylines & Theme

This is a traditional type of slot, with 5 reels, 3 rows and 15 selectable paylines. All wins are paid from left to right, except scatters which pay when they appear in any position on the reels. The mermaid theme is captured with plenty of authentic symbols and underwater sound effects. There are some handy settings and options, including autoplay and bet max. The game boasts the treasure bonus feature, which is a pick and win bonus game. There is also a free spins feature, where all wins are tripled. You will find further details about those two key features a little later in this review.

Mermaids Millions RTP, Symbols & Payouts

Given the mermaid theme of this slot, it is hardly surprising to find that the highest paying symbol is King Neptune. Get 5 of these symbols on an active payline and you’ll earn x7500 your line bet. Furthermore, King Neptune is the wild symbol. It substitutes for all others, except the scatter and bonus symbols, helping to complete winning combinations. The mermaid is the scatter symbol, with payouts made for 2 or more anywhere on the reels. It is also the trigger for the free spins. Other high paying symbols include jewels, an oyster and a seahorse. The lower valued symbols are represented by the symbols A – 10, each embellished with a little under-the-sea bling.

Mermaids Millions Paytable
Advantages:
  • Pick and Win Bonus
  • Free Spins
  • Wild Substitutions
  • Scatter Pays
  • High RTP
  • Fun Theme
Disadvantages:
  • No Progressive Jackpot
  • Graphics a Little Dated

You can opt to play this game with between 1 and 15 paylines. Of course, you get the most entertaining gameplay by playing with all 15 lines active. You can select how much you want to bet by adjusting the coin value between 1p and £5. Furthermore, you can play with between 1 and 5 coins per line. Therefore, to play with all 15 paylines, you can bet between just 15p and a huge £375 per spin. That wide range of betting limits makes the game suitable for all types of players. The highest possible payout from a spin in the base game is x112,500. Yet landing 10 free spins with triple payouts can boost this even further.

Bonus Round, Free Spins & Progressive Jackpot

The treasure bonus is a highlight of the game and is triggered by 3 or more bonus symbols on an active payline. You are presented with various underwater objects, like shells, chests and barrels, which each hide a different cash prize. You must pick between 3 and 5 of these items (depending on how many bonus symbols triggered the round), then their values are added together and awarded as a cash payout. The other key feature of the game is the free spins bonus. Get 3 or more mermaid scatter symbols in any position on the reels and you will get 10 free spins.

I found the treasure bonus was triggered quite frequently during gameplay. The more symbols that trigger the bonus, the higher the possible payout. Get 3 symbols and your prize will range between 36 – 1500. This increases to 48 – 2000 for 4 symbols and 60 – 2500 for 5 symbols. Yet it is undoubtedly the free spins that provide the possibility to stack up the biggest wins. All wins are tripled for the duration of the free spins, meaning this can be a rather lucrative round. That explains why it is triggered less frequently than the treasure bonus.

Mermaids Millions Mobile

This slot has been optimised for mobile play. So, you can experience all the fun the game has to offer anytime, anywhere. The layout of the game has been simplified to ensure you get the best possible gameplay on the smaller display screen of mobile phones and tablets. Whilst the desktop version of the game lists the paytable one just one screen, this is separated into 2 screens on the mobile version, ensuring that you can easily see the key details.

Mermaids Millions Reviewer Opinion

Granted, the graphics and sound effects are dated, but you have to remember that this Microgaming slot got released in the late 2000s. Despite that, the fantasy mermaid theme is quite amusing and still relevant today. Moreover, you can take advantage of huge potential wins up to x112,500 your stake, when you play Mermaids Millions. Also, this old-school Microgaming slot is optimised for mobile play, so you can enjoy it everywhere you go.

Slots Like Mermaids Millions – Similar Games

This slot boasts a retro style of gameplay, that many players enjoy. It is simple and straightforward to play, with plenty of features to keep it engaging. The inclusion of a free spins round helps to boost your payouts. Plus, with all wins tripled, it can be a highly lucrative feature. Also, the treasure bonus is a fun feature that can provide you with impressive rewards. Of course, the old-school game does not boast the cutting-edge graphics and innovative features of many more modern video slots. If those qualities are important for you in a slot, then check out these alternative games which you may enjoy.

It provides a nostalgic feel that adds to the entertainment factor. If this slot sounds like your cup of tea, then head over to Betway Casino, the best place to play the slot for real money.
