Exploring the Deep Blue Sea

The visuals of Mermaid’s Millions Slot live up to the standards set by any video slot machine at the time. The video slot transports players to the bottom of the deep blue sea, where there is nothing to be seen. The transparent five-reel grid that provides a view of the clear waters is surrounded by a school of fish.

For instance, J is tangled in the arms of a pink octopus while A is paired with a cowering red lobster.

Slot Winnings

The Mermaid’s Millions slot machine is generous with payouts given at random, without regard to player skill, during any spin. The following icons that appear with each new round determine the winnings:

  • Payline combinations
    Mermaid’s Millions Slot has eight regular characters that award winnings when three or more appear on a bet line. Any or all fifteen play lines can activate in a single round, and only the most valuable combo is granted per line. The paytable adjusts its values according to the selected wager. Here are the expected wins when the highest stake of 150 credits is used:
  • Wild
    King Triton plays the wild in Mermaid’s Millions slot machine that can replace all other characters to trigger or extend their winning combinations. King Triton can land on any reel and also pays for combinations of his own. He is the only payline combination icon whose two-symbol combo is valuable, and it pays up to 50 credits. Three, four, and five of the symbols grant 2,000, 20,000, and 75,000 credits for 150-credit bets.
  • Scatter
    Mermaid’s Millions online slot displays its scatter as a beautiful blonde mermaid with shell decorations in her hair. She is one of two symbols irreplaceable by the wild. The scatter can appear anywhere and is the only icon that pays without being restricted to appearing on the fifteen paylines. The symbol’s combos are also multiplied by the total bet rather than the line stake. Two, three, and four of the icons provide 300, 600, and 7500 credits. The highest win is reserved for five scatters, and they pay 60,000 credits.
  • Free spins
    The Mermaid’s Millions free spins activate when three to five mermaid scatters are in view. The freebies use the same bet value as the triggering spin, and they start playing immediately they activate. Any wins collected in the boon are multiplied by three, making the maximum combination payout 150,000 credits by five King Triton symbols. However, the multiplier offer does not apply to scatter wins. The free spins reactivate if three to five more scatters appear.
  • Treasure Bonus
    The closed treasure box is the second Mermaid’s Millions symbol the King Triton wild cannot replace. The icon acts as a scatter that awards random wins when three to five appear anywhere on the grid. The Treasure Bonus payout range varies depending on the number of bonus symbols in view. Three characters grant 360 to 15,000 credits, and four of them award 480 to 20,000 credits. The highest values of 600 to 25,00 credits are kept for five bonus icons.

Mermaid Millions Review

Theme and Story Line

Mermaids Millions slot machine takes you down under the sea, where Neptune rules and the mermaids play. There is sunken pirates’ booty and all manner of sea creatures as well as the mythical mermaids who deliver the big bucks.

While taking care to avoid upsetting Mickey Mouse’s copyright lawyers, the theme is obviously inspired by Disney’s The Little Mermaid.

Take it from me, the lobster, everything is better down where it’s wetter.

Graphics, Sounds and Animations

The animations and graphics are expertly done and in high definition. On any size screen, they look fantastic. Although the blue background can be a little taxing on the eyes, the visuals are effective because the Symbols stand out against the color.

A pleasant underwater bubbling noise serves as the spins’ soundtrack and is oddly calming. The soundscape begins to wake up a little bit as the reels are spun, and the typical chimes and spinning noises can be heard.

Overall Mermaids Millions looks good and sounds good.


A five-reel slot machine with one to fifteen paylines is the basic game.

By landing on the Scatter or Treasure symbols, one of two bonus games is activated (more on these games below).

The slot is easy to get into and all the controls are highly intuitive. By switching on the expert settings you can set up the auto play options, or else use the preprogrammed 5x and 10x auto play buttons.

It all makes for a well-paced experience.

Wilds, Bonuses and Free Spins

The Mermaid and Treasure symbols are the game’s two bonus symbols, as was already mentioned.

A Scatter, the Mermaid icon. But if you get three or more of the Mermaid symbols, you’ll also get a 10-spin free spin bonus. Every payout is tripled while you are in the free spins.

A bonus symbol is the Treasure icon. It starts a minigame where you can open various boxes to win prizes. You can open more boxes if you hit the bonus with more symbols. During the Free Spins, you can still receive the treasure bonus.

Plus, the Neptune symbol is extremely powerful. Should you land more than one of this wild symbol on a winline, they will all pay out separately as well.

The Neptune symbol can assist with hitting any winline apart from the Scatter (Mermaid) and Treasure symbols.

Bet Sizes, RTP and Variance

The RTP for this game is respectable at 96.56%, which is about average for the sector.

The maximum number of coins per spin is 75. The site we tested, however, allows you to set the coin value from anywhere between $0.01 and €/£/$1.00, providing you with more than enough flexibility in terms of bet size (a bet spread of between €/£/$0.01 and €/£/$75.00 per spin).

Mermaids Millions is a medium volatility slot with a maximum single line payout of 7500 times the line bet (for five Neptune symbols) on a regular spin or 22,500 times during free spins.


Mermaids Millions is a visually appealing slot machine with good gameplay and a surprising number of bonus features.

Since its RTP is fairly typical, we would advise increasing the volatility by playing fewer winlines for our suggested strategies.

Overall, it’s a respectable slot that is simple to recommend.
