The slot is a choice of thousands due to the high chances to hit not bad money with help of Bonus Games. That’s why I play the game often. All left to add to the slot to make it perfect is progressive jackpot ahahah

I like the game’s Treasure Bonus — it’s really win-win feature with guaranteed prize to grab. Besides, Free Spins Round are worthy of the attention.

Microgaming is the leader among other gambling providers as for me. I like almost all creations of the software, but this is the fav one.

Mermaid’s Millions slot is almost a classics of 5 reel games. Surely, today there are lots of games with the better graphics, but still I like this one because of its simplicity and bonus features offered.

Yes, Microgaming software is another word of quality. This slot game is a proof of that. Though the slot was released years ago, it’s still popular due to the features and stable working.

I think that such slots like Mermaid’s Million should be progressive. It would be much better and really interesting for real money play.

Can you say if I can to play the slot via iPhone?

Yep, it’s compatible with Apple gadgets. Just check if the OS is up to date for smooth gambling action.

Oh, the old graphics and not such a vivid animation of the slot is a long story, but you can’t discard that when it comes to bonus features Mermaid’s Millions is really cool game to try. Free Spins at 3x Multiplier and win-win Treasure Bonus are bound to make your heart run faster :)))

Though the such number of new providers, Microgaming remains the leading one. It’s not only about the quantity of the products, but also about their quality. Looking at Mermaid’s Millions and its popularity even today, you can see that all the awards given to the supplier are not for nothing.

I’m not agree with that. Yes, the group was cool, but was, not is. They hadn’t released nothing actually new recently. All new games are changed in the themes, but not in features. It’s a pity and makes players choose games by another software suppliers.

It’s a pity, but Deniel’s words have a grain of truth. It’s about supply and demand. If users are seeking for such features as Mermaid’s Million slot offers, why not to upgrade the design only then? Microgaming team consists of the true pros and get awards not just like that.

If we’re talking about the upgrade, why the supplier didn’t make the slot more modern in graphics due to its high popularity?

Actually, they released another game with similar theme. It’s Ariana Slot Machine, though lots of players still choose Mermaid’s Millions anyway.

The slot game is really not bad. Low stakes, high payouts and great bonus features to trigger. What else you need? It’s all I want to have when playing 🙂

Don’t like these changing up of the supplier new games. Once it came in 1994, it has been making advances in the industry. Now, one by another video slots have similar features, paytables and other alike possibilities, except for a plot, maybe. At least, Mermaids Millions is not one of them. What is price glory of their 850-game collection then? Sure the company should work on improving the points first:

  • copying video slots;
  • add more paylines;
  • implement more bonuses into new titles.

Can we have it all? Briefly about Microgaming in figures: 1994 (appearance), 850+ games, 10 (casino, bingo, multi-player, quickfire, sportsbook, land-based, business solution, live dealer, poker, mobile platforms), 45+ (languages) compared to 25+ averagely, 25+ currencies down from several popular units upon average. Should I go on? That’s why, I confide in the company, at least I know where my money goes (he-he), I try believing, it spends on such improvements, upgrading of Microgaming, herewith the quality of gamblers’ service. I also support the idea to watch after the operators (have read about on the Microgaming website) and how they administer the products.

I find Microgaming a bit pompous. So, guys, if you are not ready to waste money, don’t be blind with their merits. They bring in a really good staff in online casinos, take Mermaids Millions or Avalon video pokies. And for 24 years already, this company has made much more progress as compared to other providers, to my view. I mean the graphics, design, plots, music, mobile play improvements. Going back to 2013, with a release of Dark Knight Rises, they conquered my heart. Hope to see more of that and less of Cool Buck, Treasure Nile slots (which do really have a low rtp, they don’t keep up to the mark already).

What is so special about Mermaids Millions? Why is there so much buzz over the slot?

Based on the stats, it has the return to player 97%, chances are high that you will hit 3 symbols of Treasure Chest or the scatter -1 to 63 and 1 to 143, plus free-spins can be hit again and again. Besides, the above said cash drop promotion, which allows to exchange your money spent on bets into the draw of a raffle ticket, it looks like it is a “loose” machine.

If it would offer progressive jackpot, I would fall for it forever. Can we assume the cash drop promotion as a kind of extra reward? Progressives can be also as small as 5,000, to add more, it sizes as an average Middle progressive jackpot.

Microgaming has made me happy for years, having a multi-language web platform, a stack of various games on HTML5 and many more of the things. It has an unchallenged reputation, hasn’t it?

Everything that is coming to my head now is a Bonus of Mermaid Millions. I want a Treasure Chest symbol to be a more frequent visitor to my play, of course, I am graceful for 3 ones, they allow me to open up those chests, full of FREE cash prizes, but also I want those symbols to appear in a bigger amount, to have 5 attempts, more trunks to reveal.

Hi there. I looked through the comments and have found nothing about the quantity of bets, sizes of your stakes, big wins of yours, etc. If someone has any of experience in Mermaids Millions, share it with me. I used to stake the minimum and spin for twenty times. If my expenses were less than wins, I continued and increased my stake after 10 or so spins. My big catch totaled 900 AUD for one day.

This 15 payline game belongs to Microgaming, I am a fan of which. The most experienced, most popular, most expanded, most repeatable software company in gambling and that is far from the full list of their merits.

It’s quite positive slot with high RTP and nice bonus features. Nothing special, but still it’s relaxing to play with low stakes.

Sure, I play the game on iPad, I also like to use an autoplay option. I put 75 coins a line and look forward to reaching a multiplier, wild combos, a bonus, there is always something caught, again and again.

Mermaids Millions slot is a creation of Microgaming company. And this is enough for me to understand that the game is of high quality. The software provide always releases profitable and entertaining fun.

When I joined Mermaids Millions slot for the first time, I played with the min $0.01 coin value, today, I increase my bet to the max $75 per spin. That is why, I am so happy to catch winnings, cause the payout is much more impressive.

I can’t get the rules till the end. The paytable doesn’t reflect all the conditions in the appropriate way. I am not a new player and I have tried a lot of other Microgaming machines, yet, this one fails for me.

Is there any Multiplier in the slot? Or only during the bonus game?

Peter, yes, there is. Mermaid is the scatter symbol and catching 2, 3, 4 or 5 of it, you gt 2x, 4x, 50x and 400x Multiplier accordingly.

I caught Treasure Bonus. For the first time! This is really existing. I got a number of chances equal to the amount of Chests I have got. This time the figure was not so high, but I hope I will have up to 5 picks, when catching 5 Chests correspondingly.

Not one, but two bonus games! I love such tendencies. The first one is pretty ordinary. You catch 3 or more scatters and get rewarded with 10 Free Spins at 3x Multiplier. All the wins caught get tripled!!! he second try is more tricky. With the help of 3+ bonus symbols, you enter Treasure Bonus Game, where 12 items are presented. Picked some of them and reveal your cash win. Intuition and the 6th sense are needed here.

Microgaming always knows how to impress its players. Its game content includes all the possible alternatives. Even speaking about Mermaids Millions slot, those who think that it is too old-fashioned, they can try a new release called Ariana. Marine theme is not limited with only these machines, the software provider also provides Alaskan Fishing, Beach Babes, etc.

If choosing between a progressive slot or the one like Mermaids Millions, I will select the second variant. This time, I have a chance to catch $37,500 jackpot, 2 bonus features, 400x Multiplier and other privileges.

When I play Microgaming games, I always feel the concern of the software provider. I am not sure how many awards the company has, but I am sure that all of them are merited. No wonder the platform is on top of the leading ones.

The slot is so old fashioned, why not to make it look more modern? In comparison with other machines, this one is behind. Guess Microgaming should think about that seriously.

Being on top since 1994? Microgaming can do that for sure. Gaining popularity is not hard when you are honest, trustworthy and do everything in the proper way. More than 450 brands use the platform on its own or in a company with others. eCOGRA license is another proof of its stability and quality.
