Slot Description

Microgaming The Mermaids Millions Slot Features

The five-reel Mermaids Millions slot machine received fifteen paylines from Microgaming. Behind the reels, you can see a bright blue background that reminds players of marine themes. The atmosphere is also recreated with colorful symbols.

This slot provides the ability to adjust the loan face value. The size of the bet and the number of active lines are adjusted according to the wishes and preferences of the user. So, both beginners and advanced high rollers will be able to play the Microgaming online slot machine.

More often than not, Neptune is not very friendly with its guests, but for the sake of the Mermaids Millions slot machine, he will have mercy and give daredevils a chance to visit his kingdom. Neptune appears in the game as wild, and, if necessary, is ready to replace the missing link in order for the gambler to be able to get a prize combination.

Scatter - a chest filled with gold and other jewelry. As befits the scatter symbol, it will delight you with a prize, regardless of which part of the playing field appears. The main condition: at least three icons with a scatter on the reels.

Also, three chests will launch the bonus game, provided that they fall on the third, fourth and fifth reels. During the round, you will need to choose three out of five shells. But if the player is lucky and four or five chests appear on the reels mentioned above, he will be able to pick up even more shells.

The free spins feature is entrusted to the little mermaid. All coefficients obtained during free spins are added up and multiplied by three.

There is no risk game to double the size of the prize after each successful rotation. But the lack of a doubling round is more than compensated by the mass of other, no less entertaining and original options.

Microgaming The Mermaids Millions slot: symbols and design

The game is filled with beautifully drawn characters. By launching the drums, the gambler will feel as if he has sunk to the bottom of the sea. Seahorses, shells with pearls, crabs, tridents, pearls and, of course, chests full of gold, make the gameplay very exciting. Everything looks very beautiful.

The control buttons are in the usual places. Here, the developers decided not to invent anything, and the players are grateful to them for this. What could be better than launching a completely new gaming machine for yourself, but at the same time quickly get to the bottom of the intricacies of control and enjoy high-quality gambling?

There are 15 lines in this game and my usual bet is €0.60. It keeps me going for a while and doesn't do much damage to my pocket. i have tried to play on higher bets but that ended very bad. There are two features in this game. There is a bonus and a free spins feature.I got the bonus feature tonnes of times, i even got five bonus symbols on a pay line and max i ever won on this bonus was around €22.

The free spins feature is better in my view and has more potential to pay out. To get the free spins i had to get three or more scatters and i have done that many times. I never got five scatters but did get four. I got 10 free spins with all wins tripled. The free spins can be re-triggered and i have re-triggered them good few times. Best one for me was when i re-triggered it three times and won over €75. Unfortunately the wins are pretty small and you have to count on the wilds. over all the game is fun and very popular.

The graphics are not too bad and the sound effects are average. I would recommend this game to everyone. Give it a shot and see how it goes. If i was to rate it i would give it 7 out of 10.


re we have wilds on all reels, which substitute for other symbols and have payout itself - x 300 total bet. Scatters here appear quite often to be honest, i am hardly remember that i ever wait more than 100 spins to trigger free spins feature, which is 10 free spins with tripled prizes here. By the way 5 scatters payout is even higher than wilds payout, here it is x 400 total bet, therefore max win in free spins is 1200 x total bet, which i think you agree with me is nice result.

Also when 3+ bonus chests appear on active payline there starting typical and boring pick bonus game, i never had more than 15 x total bet here. Last time i played this game at betat casino few months ago, i had 20$ only and decide bash a game with 1.5$ bets, but imagine how i was excited when i hit free spins on third spin and after it has 150$ on my account! I make few more spins, hit bonus game, and already had 200$. Lol, of course i find withdrawal button without problem.

Great medium variance game, well balanced and i really love layout, very colourful and symbols are nice. I will play this game again, i am sure, also this game available to play from mobile devices, i played it once from tablet.


I like very much the bonus feature, when I have to choose 3 objects and to see how much I’ve won but he problem is the way this bonus is triggered. Well, you have to catch 3 bonus symbols, but on an active payline in order to get the bonus. My biggest win from this bonus was only 11 euro on a 0.30 euro bet, decent but I was expecting for more. It has free spins feature too, but this feature is a little bit harder to catch, most of the time I get only 2 scatters and the 3rd one won’t appear. That’s a little bit frustrating because it has to be some kind of balance between these two features but instead of this, the bonus feature is triggered easier.

When I had only 0.40 euro in my account, I managed to catch 3 scatters and I won 10 free spins with 3 x multiplier. These free spins helped me to recover my balance and also to make profit a couple of minutes later.

Now, regarding the graphics, are not quite good, I would rather say decent, even if it’s an old game, it has nice symbols and interesting theme, so I will give an 8!

The bonus and free spins features are decent I could say, it has also a wild symbol that is doing his job very well, so I will give another 8!


love ocean themes in slots, but here it is does not work. There is 15 paylines.

Base game at this slot is quite not interesting. Wild symbols here appears on all reels, and have itself very good payout, but unfortunately wilds does not have any multiplier, and thereof there is no difference to see if wild substitute or not. Also payouts for everything else except wilds and scatters is quite sucky, this is not what I am want to see in slot games.

There are two features. First one it is bonus game, it can be triggered by bonus symbols on payline (at least 3 needed, but more - better). Just pick shells to get prizes, nothing very interesting, but usually something like 10-30x total bet from my experience, and this is not so bad, since this feature triggered quite often.

Freespins can be triggered by 3 or more scatters, and you will be awarded with 10 spins with tripled prizes, and nothing else. Quite boring.

Unfortunately after trying this slot game couple of times I decide that I will not play this game again, it is just not interesting. It could pay decent, but in extremely rare event.

As like the other older Microgaming games, there is also a lot of attention to the details and symbols. I like the most the wild symbol that represents the King Neptunes. It is an interesting animation when King Neptunes winks every time you replace some of the symbols on the pay-line.

This game offers two features. The first one is a classic pick up bonus and it is called a “Treasure bonus”. To reach this bonus you need to have at least 3 bonus symbols on a single active line. Another feature is a free spins feature. It is activated by at least 3 scatter symbols anywhere on the screen. You get 10 free spins and all the wins during the free spins are tripled. I am just going to mention that free spins can be retriggered. That is all for the feature in this game. Even though I like the design of the game, for my taste, Mermaid Millions is a little bit boring and a slow game. Reels do not rotate as fast as I would like.

When it comes to my experience with this game I have to admit that it has been a long time since I last played it. I have not made any spin on this game probably longer than a year. So I can’t say more about the wins that I have had here. But a look at the pay-table tells me that this game could pay you very well. Let’s say 5 scatter symbols pay 400 x bet. Or let’s say 5 wild symbols on one active pay-line will pay 5000 x line bet. While 4 wild symbols on one active line will pay 2000 x line bet.
Mermaids Millions is a game that I think deserves 7 out of 10 possible stars.


to free spins feature there is 10 free spins with x3 multiplier. When I played this video slot i never trigger free spins feature. Maybe the reason was because I played it only for a couple of minutes and later I changed the game. But I had a bonus game several times during my different gameplay sessions.

The bonus game based on pick up choice. You have to pick out three treasure boxes and you get prizes. I mostly won here winnings which were not higher than 10€, from 0.15€ to 0.45€ bets. I think here at bonus game you can not win big money, maybe only from free spins feature. But I liked that I received many times bonus game, which was better than without it.

I don't think this is a powerful game. I played it a few times, but I had only small winnings. Never more than x 100 bet or something like that. And I don't think I will play it more in the future. The only reason is because the game has old design. It really looks old and I usually don't play this kind of games. The only reason why I would play this kind of games would be if there is great, powerful paytable which could provide huge winnings. But I don't think I can win big money here, so I will play other games.

I will rate this game with 6 stars. For me it is better than some other older games from Microgaming, but it is not great one.


e graphics are colourful and almost comic book style, amd despite the games age Mermaids Millions still looks reasonably good to me. Sound effects are quite basic as was common at the time of this games release and that is one area that does show the games age.

As a fifteen line slot you expect the base game to have some fairly decent wins, but this isn't a super high variance game - only a full line of wild symbols is going to return a huge win in terms of multiple of stake. If your betting bigger though this type of game can be perfect for making a decent sized profit without too much risk. It's also a good game for playing through a wagering requirement.

Three or more scatters start the free spins, sadly there is no additional bonus offered for four or five scatters but you do get a 3x multiplier. There's a second "Pick Me" bonus too which can also be awarded during the free spins, although bonus wins do not receive the 3x multiplier.

All this will no doubt sound familiar to players of Tomb Raider, but if you haven't yet tried either of these games then which one you choose should be decided purely based on the theme you find most attractive. Personally I enjoy both games, but Tomb Raider just feels a little more polished and up to date which is enough to swing my bets over to that game.


Are mermaids real? Who knows for sure, but you can be sure that whatever mermaid you are playing with, can certainly be good for you, or otherwise. This mermaid, for instance, promises you millions in winnings, but whether it is for you or for the game provider, your guess is as good as mine. I tend to think of the latter, hahaha.

The King of the oceans, Neptune, is the Wild symbol, 5 of him pays 7500x the line bet, and does only substitution for other symbols except for the Scatter and the Bonus symbols. No doubling of wins, no expanding, no stacking, no nothing. Makes the King a dumb King. Oh, okay, the symbol, not the King. The Mermaid is the Scatter symbol, 5 of her pays 400x the total bet amount, which is very good, and getting 3 or more of these Scatters trigger 10 free spins with all wins tripled. More free spins can be retriggered. Should have been 15 free spins instead, but what to do, Microgaming doesn't want to give everything to me and you. The Chest is the Bonus symbol, which doesn't pay anything for itself, damn, and getting 3 or more of them on any payline triggers the Treasure Bonus game. All the other symbols pay from 500x the line bet to 75x the line bet, for 5 of each kind. A good paytable.

In the Treasure Bonus game, pick 3 chests out of the 12, to reveal cash prizes, to win up to 2500 coins, or 166x the total bet amount. Good, if you can get that much. All my pickings from the numerous Bonus games that I've played all paid between 3x - 20x my bet amount. Hmm, imagine just how difficult it must be to get that 166x win! As for the Free Spins game, again from the many games that I've played over the years, I've gotten only a very few retriggers of the Free Spins game, and my best win to date was only 121x my bet amount. The worse case that I can still remember was getting only 1 paying spin out of the 10 free spins, for a miserable 5x my bet amount win. That sucks.


If your wondering about the bonus game it is no more than the feature you would find under the first Tomb Raider slot's Idol bonus. Instead of seeing Idols all around there are different Chests and shells to open for credits. The amount of picks available to medepend on how many treasure bonus chests I can line up on a payline. It can be real tricky to find them. Now I don't know which is worse? Treasure bonus symbols missing the 3rd symbol on Reel 3 for a trigger or Mermaid scatters that pay for 2 and occasionally granting the 10 free spins.

Since Mermaids are mythical and possibly shy creatures it is sometimes hard to get them to appear in threes but the second I hear a high pitch tone followed by a giggle coming from these scatters then let it be assured, that is a signal to win triple on the next 10 spins. The least I always expect on Mermaid Millions is about $8 when after triggering free spins + playing them out and most of what I can get inside are $20 - $30 total on a bet of $0.75, coin sizes lowered to it's lowest and also with or without a treasure bonus within the feature. In my humble opinion Microgaming should change the title of the last word "Millions" because it sounds to me like this is a progressive slot which I know isn't.

I will continue to be a loyal player on Mermaids Millions but I have to admit you can expect to have fun on this slot! Truly an 8 out of 10!

Pontiwell Rodriguezanic

I don’t like the way the bonus feature is triggered and also the very hard to catch free spins feature!

Houghtonobby Dortinez

Can be decent game in very rare event, generally - just waste of time.

Poozzt Doshar Elfcollins

It is very hard to trigger the bonus feature and I also could not catch the free spins either. I do not know if I had bad luck or this is another game that is not willing to pay at all.

It is a very old game run by the Microgaming software. It is 5 reel 15 pay line game where everything is bright and sparkling where even the card symbols are decorated with fishy elements. Some of the symbols include a seahorse, a pearl inside a clam and a container full of jewels. The mermaid is the scatter symbol, and the male version is the wild symbol. The treasure chest symbol triggers the bonus they say, I did not get the chance to see that.

If you get 3 or more mermaid symbols you will get 10 free spins and all your wins will be multiplied with 3. If you get more scatters within the bonus game the free spins can be retriggered. Treasure bonus is the secondary bonus and you will need to land 3 or more treasure chest bonus symbols on an active pay line. If that happens, which I doubt, you will be taken to an underwater setting which contains a range of object. You can choose only 3 and each of them will reveal a cash prize. Another interesting thing about this game is that the bonus feature can be triggered within the free spins round. The only thing I can say to you is give it a try, maybe it will treat you right.


I had expected a much better gameplay from Mermaids Millions, considering that the paytable was good, but I had always ended up disappointed, with not a single withdrawal win over the years. That is actually quite ridiculous, because I could always get wins from other provider's games, but almost never from Microgaming.
