Featuring 5 reels, 3 rows, and 15 fixed paylines, Mermaids Millions is an underwater-themed, low-volatility slot from Games Global that is available to play right here at MetaWin Casino. After diving into the game, you'll soon discover seahorses, giant clams, and buried treasures, in addition to bonus rounds, Scatter symbols, and more. The crypto slot's maximum win is up to 1,655x your stake, primarily driven by its Free Spins round and Treasure Bonus pick game.
Mermaids Millions was created by Microgaming (Games Global) and released in 2005, before the HTML5 version was released in 2008. When Microgaming reorganized in 2022, ownership of the game was transferred to Games Global. Mermaids Millions is a 5x3 slot with a low volatility, which means you can expect smaller but more frequent wins.

The visuals and sound may be a tad dated, but the game remains popular today due to its simplicity and availability of two different types of bonus games: a Treasure Bonus and a Mermaids Millions bonus Free Spins round with a 3x Multiplier.
During the base game, the idea is to land three or more identical symbols, starting at reel 1, on any of the 15 paylines. You will be paid for every winning combination you form, and not just the highest paying one.
Landing three or more Treasure Bonus symbols on a payline will activate the Treasure Bonus mini-game. It's a pick 'em-style game in which you open sunken barrels, treasure chests, and giant clams that contain random cash prizes.
If you land three or more Mermaid Scatters, you'll earn a round of Free Spins. A 3x Multiplier is automatically applied to all winnings. The King Neptune Wild is the highest paying symbol, and it substitutes for all other symbols except for Scatters.

If you're interested in playing Mermaids Millions, you can get started by following these 5 steps.
Because Mermaids Millions was created way back in 2005, it doesn't offer any of the most modern features, like Cascading Reels, Hold & Win, or Cash Collect. However, it has two different bonus games.

Landing three or more Treasure Bonus symbols triggers the Treasure Bonus mini-game. You'll see Treasure Chests, Barrels, and Giant Clams on the screen. Each one contains a random cash prize, and all you need to do is select which ones you want to open. If you triggered the mini-game by landing three Treasure Bonus icons, then you can select 3. If you got there by landing four Treasure Bonus symbols, you can pick 4, while landing five Treasure Bonus symbols gives you 5 picks.
The Mermaid Scatter is a flexible bonus symbol. Not only does it act as a high-value pay symbol that only requires you to land two of them to win a prize, but it also triggers a round of Free Spins. If you land 3, 4, or 5 of them, you'll earn 10 Free Spins with a 3x Multiplier. You can trigger more Free Spins during the round by landing 3+ more Mermaid Scatters.
Then there's the King Neptune Wild. In addition to being the highest-value pay symbol, it also replaces all other symbols except for the Scatter. Also, you only need 2 of them to appear to earn a cash prize.
