Since first swimming into online casinos way back in 2005, the Mermaids Millions slot has become a firm favourite with aquatically minded players. This Games Global title is a 5 reel, 15 payline game that comes with a pair of classic bonus features. The Treasure Bonus feature is a Pick Me round where choosing chests can deliver sunken ocean riches. The other is the Free Spins feature. Once triggered, you’ll play up to 20 free spins. All winning combinations during the free spins are boosted by a 3x multiplier with the payout trebled. Is it still worth diving into these rather retro waters? Find out in our deep dive Mermaids Millions review.

Mermaids Millions Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 15 paylines

Stakes Range: 15p to £150 per spin

Max Win: 1,500 x stake per spin

RTP: 96.56%

As you might expect from such a vintage offering, the setup in the Mermaids Millions slot is very straightforward. The action takes place on 5 reels, 3 rows and 15 paylines. To create a winning combination land 3 or more matching symbols or 2 or more wilds on a payline, starting from reel 1.

Stakes in this underwater adventure range from 15p to £150 per spin (the latter is for the high rollers with extremely deep pockets). To change your stake level, click on the coins to the right of the reels then pick your level. Above the spin button, you’ll see a circle made up of 3 arrows. Click on this to activate the autoplay function. This allows you to run between 5 and 100 autospins, but it’s not available to UK players.

The Mermaids Millions RTP is 96.56% which is well above average. These are tranquil waters when it comes to variance. The volatility is low.

The hit frequency rate of 34.29% means that you’ll land a winner on just over one-third of spins on average.

The max win is 1,500 x your total stake per spin. This is best achieved in the Free Spins feature with the 3x multiplier.

mermaids-millions-slot-base-game

A slot released in 2005 was never going to have the design flair we’ve come to expect from new slot games. The Mermaids Millions slot game is very simple, yes, but the cartoon-style graphics still do the job here pretty well. You’ll hear the bubbling of the sea while you spin as well as the occasional haunting bleep. Despite its age, the sound and visuals stand up pretty well.

With the deep blue ocean in the background, the reels include A to 10 royals embellished with starfish, octopus, pearls, a trident and a lobster. More rewarding are the seahorse, oyster and pearl and pot full of gems. The pot full of gems symbol pays the most with a payout equal to 3.33, 6.66 or 33.33 x your total stake for 3, 4 or 5 on a payline.

The bearded figure of Neptune is the Wild. He can land anywhere and substitute for all the standard symbols. He can be very lucrative too. Land 5 wilds across a payline for an award of 500 x your total stake.

Mermaids Millions Mobile

Tablets were even a thing when this slot was first released. Now, you can play Mermaids Millions on smartphones, tablets and computers as Games Global (Microgaming) has revamped this favourite since it was first introduced. The simple, colourful graphics and straightforward gameplay make the Mermaids Millions mobile slot a very easy one to play.

Mermaids Millions Bonus Features

Mermaids Millions comes with a couple of classic bonus features. The Pick Me bonus can deliver plenty of sunken ocean treasure with the free spins offering some decent winning opportunities thanks to the 3x multiplier which is active throughout.

Treasure Bonus feature

mermaids-millions-slot-treasure-bonus-feature

The Treasure Bonus feature is triggered by landing 3, 4 or 5 Treasure Chest scatter symbols on a payline, starting from reel 1, on the same spin. It can be activated during the base game or the Free Spins feature (details below).

Once triggered, you’ll drop down to the seabed where you’ll be offered a selection of 12 treasure chests. Pick one to reveal a cash prize. The number of picks you’ll receive depends on how many Treasure Bonus scatter symbols you hit on the triggering spin.

3, 4 or 5 scatters will give you 3, 4 or 5 picks respectively. This is what you can get depending on the number of scatters you got to trigger the feature:

  • 3 scatters = 2.4 to 100 x your total stake
  • 4 scatters = 3.2 to 133.33 x your total stake
  • 5 scatters = 4 to 166.66 x your total stake

Free Spins feature

mermaids-millions-slot-free-spins-feature

To trigger the game’s Free Spins feature, you’ll need to land 3, 4 or 5 Mermaid scatter symbols on the same spin. After pocketing an award equal to 4, 50 or 400 x your total stake, you’ll go on to play 10 free spins.

All standard payouts are boosted by a 3x multiplier and trebled. The only exception to that is if you land 3 or more Mermaid scatters. That doesn’t get the multiplier boost but it does result in the standard payouts plus another round of 10 free spins, complete with that all-important trebling multiplier. The 3x multiplier is what can lead to 1,500 x stake payouts on each free spin.

Originality








Manage your expectations and you’ll find plenty to like in the Mermaids Millions slot. As you’d expect from such an old game, it doesn’t really compare to today’s super slick slots when it comes to design.

The gameplay is rather basic too, but still nice to play. But don’t expect visuals seen in slots like Bass Boss (Red Tiger Gaming) or Pearls, Pearls, Pearls (Playtech).

You can’t go too far wrong with Pick Me prizes and a free spins round where all payouts are trebled. The RTP numbers stack up well and the low volatility offers plenty of play. It might be an oldie but Mermaids Millions still has its charms.

If you want more underwater adventures, the Lord of the Ocean slot by Novomatic is a classic and comes with 5,000 x stake wins per spin. And if you’re looking for another mermaid-inspired slot, try Mermaids by NetEnt.

Pros
  • Low volatility
  • RTP rate above average (96.56%)
  • Great on mobile
Cons
  • Low max win (1,500 x bet)
