Slot Details

Mermaids Millions was released in 2008 and is therefore one of the older games on the market. However, despite this it still holds up with some of the newer games out there. Some might say that the graphics are slightly dated, but as they use a cartoon style they are pretty much timeless. It’s not like 3D graphics that will look poor in comparison to newer visuals, cartoon style graphics are able to maintain their freshness over time. The game has two different bonus features, both of which are excellent. It’s definitely an enjoyable game that has stood the test of time.

RTP and Volatility

Mermaids Millions has an RTP of 95.56%. It’s slightly below the market average, but it’s by an extremely small amount. The RTP means that every 10,000 credits that are wagered on average will return 9,556 credits. Obviously, this is an average so it won’t be exactly this on every game that’s played.

The volatility (1) for the Mermaids Millions slot game is set at low to medium. This ensures that the game provides regular wins to players. However, lower variance titles do mean that the size of the wins aren’t quite as high. What makes low volatility games so popular is that they are very accessible to newer players. It ensures that players can get to grips with the game when first starting out and still get plenty of wins coming their way. They also don’t require such complex bankroll management which makes them easier to play.

The biggest wins in Mermaids Millions are available in the bonus rounds. This is normally how slot titles structure their payouts. With wins tripled in the free spins round it makes this the best round to aim for.

Max Win

The maximum win in Mermaids Millions is set at 1,500 times the player stake. Players are able to win this by filling up a payline with wild symbols during the free spins round. As a full payline of wilds pays out 7,500 times the line bet, which equates to 500 times the player stake, with the win tripled in the free spins it becomes 1,500 times the stake.

Theme, Graphics and Audio

The graphics in Mermaids Millions are fantastic. The cartoon style holds up very well and they really look good on the screen. The colours have a pastel effect, which matches up to the underwater theme of the game. It’s evident from the moment you start playing what the theme of this game is, everything in the game is based around the sea and mermaids.

Obviously the symbols are the first thing that people will look at when it comes to the theme and they don’t let anyone down. Even the playing card based symbols have a little bit of an underwater feel. Added to this the sounds are also in line with the theme. It means that the game is a very well put together title that really makes sure it sits in line with the overriding theme.

How to Win at Mermaids Millions

Game Rules

When you get started with Mermaids Millions it’s obvious that it’s a relatively simple game to play. The reels are set at 3 by 5 and there are 15 paylines in place. The bonus features in the game are easy to understand but they do offer players some nice rewards. It helps to split up the base game and makes things a little more interesting.

Players are able to set an autoplay feature, this definitely makes things a bit more simple for people who play with bankroll management in place. So if you want to play a specific number of spins with your budget, you have the ability to set them to play without you having to keep count manually.

Betting Options

The coin value for Mermaids Millions is set at between 0.01 and 1.00. Players also have the ability to wager between 1 and 5 coins on each payline. Because of this range of wagering options it means that players can bet between 0.15 and 75.00 on every spin. 

Symbols and Values

All symbols in Mermaids Millions are linked to the theme of the game. It means that everything has a sea or underwater look to it. It even links with the playing card symbols that all have something from the sea attached to them. It makes the game interesting visually as well as ensuring the theme is at the front of everything that’s going on.

The high paying symbols in the game are as follows:

• Gem Chest
• Oyster
• Seahorse

Mermaids Millions use the playing card symbols for the lower paying symbols in the game. The symbols all have different aspects of the sea added to them to make sure that they stick to the theme closely. They are very well designed and look great. Here’s the low paying symbols you can expect to see in Mermaids Millions:

• Ace
• King
• Queen
• Jack
• Ten

Wilds, Scatter, Bonus Symbols

The king of the sea is the wild symbol for Mermaids Millions. When it is used in conjunction with other symbols it can help to create a win. It can also begin creating wins when at least 2 of the symbols land consecutively on a payline.

There are two scatter symbols included in the Mermaids Millions slot. The first is the mermaid which is used to trigger the free spins round. The second is a treasure chest which activates the treasure bonus round.

You can see all of the different payouts in the paytable below:

All payouts are multiplied by the line bet except the mermaid scatter 

Mermaids Millions Slot Features

There are two different bonus rounds featured in Mermaids Millions. The first bonus is the treasure bonus round. This is linked to the treasure chest scatter symbol, which makes sense. The second bonus round is a free spins round which is linked to the mermaid scatter symbol.

Treasure Bonus

The treasure bonus round starts when players manage to land at least 3 of the treasure chest scatters on the reels. When this takes place players are offered the chance to enter the treasure bonus, which is a picking round. 3 scatters awards 3 picks, 4 scatters awards 4 picks and 5 scatters awards 5 picks. This means that obviously, the more scatters you land the higher the potential win that’s available.

3 scatters awards a prize of between 36 and 1,500 times the line bet. 4 scatters awards a prize of between 48 and 2,000 times the line bet. 5 scatters awards a prize of between 60 and 2,500 times the line bet. 

Free Spins

The free spins feature will trigger when at least 3 of the mermaid scatter symbols land on the reels concurrently. This will instantly award 10 free spins to players. This might not seem like a large amount, but during the free spins any wins that are created are instantly tripled. It means that the round is potentially a very lucrative one. On top of this, whenever 3 or more scatters land during the free spins round an additional 10 spins will be added to the total. 

There is also an instant win paid out when the free spins are triggered. With 3 scatters paying out 4 times the player stake and 5 scatters paying out 400 times the player stake. The treasure bonus can be activated during the free spins round too, although it pays out at the standard rate and isn’t tripled like other wins in the free spins.

Mermaids Millions Slots for iOS, Android and Windows

Mermaids Millions might be one of the older games on the market, but Microgaming has still undertaken the hard work required to make sure that it’s available to as many players as possible. It took out an update in 2020 to make sure that it had an HTML5 (2) base in place. This made sure that it is fully compatible with mobile devices. So, this allows players on iOS, Windows phone and Android devices to get the full Mermaids Millions experience. 

Tips and Tricks

When playing video slots there are no guarantees of creating wins. This is due to the random nature of how the reels are calculated. Video slots use random number generators to set each spin. This means that it’s impossible to successfully work out what is going to happen on each spin. So, this means that in order to increase chances of winning, players will have to try a few different tips and tricks.

Keep on Spinning the Reels

Just like most video slots, Mermaids Millions offers the best prizes to players during the bonus rounds. It’s very unlikely that the bonus rounds will be triggered in just a few spins. It means that in order to give players the best chance of grabbing the best wins it will need a large number of spins. Set your budget at a level that will allow you as many spins as possible. This will give you the best chance to activate the bonus rounds and get access to the larger wins.

Never Chase Losses

Without a shadow of a doubt the most important aspect when playing any casino game is to avoid chasing losses. So many players try to keep playing if they have played through their budget. This is the easiest way to cause yourself trouble and potentially get into a gambling problem. It’s also important to know when to walk away if you’ve made a profit. Keep your winnings and walk away at the right time.

Give the Demo Mode a Go

The random number generators that are in place might cause players to avoid trying them out. However, despite this it’s still important to play the demo before playing for real money. Many players don’t realise that you can learn a lot about how the game mechanics work by playing the demo. While it won’t guarantee how the game will play when playing for real money, what it will do is give you the ability to make an educated guess as to how many spins you will need to budget for.
