Mermaids Millions is available for real money play:

To get started, sign up for one of our recommended online casinos and make a deposit using any of the UK approved payment methods. Once the funds are processed, you can access all the casino games through the web-based platform, or a dedicated mobile app, if your casino has one available. New players of our recommended casinos are often eligible for a Welcome Package Bonus, which is a great way to start playing.


If you want a chance at walking away with the big £75,000 jackpot, you will need to make the max bet of £150 per spin. Then all you need to do is spin the reels and hope that you can line up five wild symbols across a single payline, and the jackpot is yours.


There are two ways to win real money at Mermaid Millions. One is to line up at least three matching symbols on a single payline. The other is to have a minimum of two scatter symbols anywhere on the board, which will result in a payout starting at 30x your line bet.

Coin Sizes:

Speaking of betting, Mermaids Millions has 15 fixed paylines. This means that the bet that you place is the line bet times 15. In other words, the minimum bet is 15p or 1p per line. This is significant because the payouts are based on the line bet and not the total bet. Similarly, the maximum bet of £150 is £10 per line.


Mermaids Millions has eight standard symbols. The highest-paying symbols are a basket of colourful jewels. That is followed by a clam, which is also filled with jewels. Both of these symbols have a similar top payout of 500x your line bet, but they differ when it comes to getting 3 in a row, there the Basket of Jewels pays out 50x as opposed to the 20x payout for the clam. The third high-value symbol is a seahorse that comes with a max payout of 250x times the line bet. The remaining symbols are the standard 10, J, Q, K, and A which have a payout range from 2x -125x.

  • Wild: Three special symbols can increase your odds of winning real money. The Wild symbol is the underwater King, and it can substitute for any symbol, excluding the Bonus and Scatter.
  • Scatter: The Mermaid scatter symbol can start creating wins when you have at least 2 anywhere on the reels. If you have three or more, you will enter the bonus spin feature. During this feature, all wins come with a 3x multiplier.
  • Bonus: The Treasure Chest bonus symbol is the key to activating the pick-and-click bonus feature. Here you will get to click on three underwater chests and see what your prize is. The more Treasure Bonus symbols you get, the bigger the prizes will be.


Mermaid Millions was developed by Microgaming, and even though the design looks and feels a bit dated, as the game was released back in 2008, it is still a very popular game for mobile and desktop punters alike. The big difference with the mobile game is the betting range is slightly different. While the minimum bet remains at 15p, the maximum bet is just £75 per spin. This means the mobile jackpot is £37,500.


Mermaids Millions is a very popular game, despite being developed over ten years ago, because the payouts are solid and the bonus features trigger pretty often. Make your deposit today and play Mermaids Millions for real money.
