The Mermaids Millions brings a hint of glamour to the underwater world with some sparkling symbols and aquatic vibes. What I like about this game the most is its retro design (the game has been released in 2008) combined with awesome features like pick-me prizes and free spins. But, let’s save the details for the full Mermaids Millions Slot Review below!

About Mermaids Millions Slot

Mermaids Millions is an online slot developed by Microgaming, a long time ago. But, it didn’t stop the game to remain popular until today! Playing on 5 reels, 3 rows, and 15 paylines, this slot can pay up to 1,500x the stake on a single spin, which is great.

Before you delve underwater to spin and win on the Mermaids Millions slot, you must select your bet per spin. This slot accepts a variety of betting options, ranging from £0.15 to £150 per spin. To create a winning combination, make sure to land 3 or more matching symbols on a payline, starting from the leftmost reel.

Design, Symbols and Graphics

As expected from a 2008 release, the design of the Mermaids Millions slot is a bit outdated, but it’s more or less a cult classic for online slot fans.

Despite being outdated, Mermaids Millions is a great-looking slot and this is noticeable upon launching. The symbols, while not drawn realistically, are extremely sharp and eye-catching. They’re bold and shiny, standing out on top of the blue background.

You can land typical playing card symbols, 10, J, Q, K and A, each of which come in shiny gold and a little added extra. The K comes with a trident and the Q with some pearls, for example. These symbols make up those of lower value in the Mermaids Millions slot.

Aside from the lower-value symbols, you can land a seahorse, a pearl inside a clam and a chest full of jewels, all of which are high-paying symbols. Moreover, the Mermaids Millions scatter symbol is represented by the mermaid herself and a merman represents the wild.

Finally, there’s a treasure chest symbol that helps to trigger the pick-me bonus game for some lucrative wins and exciting action.

RTP, Variance and Payouts for Mermaids Millions Slot

Mermaids Millions is a simple and straightforward slot with excellent numbers. When it comes to the RTP rate, here it is above the industry average, ad 96.56%. In addition, the variance is low, so winning combinations will come very frequently! In total, you can win 1,500x your bet per spin.

Gameplay and Features on Mermaids Millions Slot

I had the luck of triggering the bonus features when I tested the Mermaids Millions slot and I must say that they’re fantastic! Continue reading to learn how to trigger them yourself.

Free Spins Feature

The free spins round is triggered when you land at least 3 scatter symbols anywhere on the reels. You’ll receive 10 free spins and each win during this round will be multiplied by three. Better yet, this round can be retriggered if three or more scatters are landed within the bonus game!

During the Free Spins feature, you can also benefit from the Treasure Bonus feature.

Treasure Bonus Feature

The Treasure Bonus feature is triggered when 3, 4 or 5 the treasure chest bonus symbols are landed across an active payline. You’re then taken elsewhere underwater and given a range of objects to choose from, revealing cash prizes along the way.

SlotsWise Verdict

Microgaming’s Mermaids Millions slot might be an old slot, but I think classic is a more suitable term for it. It’s no wonder that this 5-reel, 15-payline slot has remained so popular over the years. With an above-average RTP and low variance, it's acceptable for most slot players.

Furthermore, the Mermaids Millions slot has a couple of exciting bonus rounds, allowing you to get even more from your slot experience. I really enjoyed the free spins round, where winnings are multiplied by three, making it all the more lucrative.

The Treasure Bonus round is also one worth triggering. Instead of free spins or multipliers, the prizes in this round are straight cash. What more could you want?
