By matching 3 or more Treasure Chest symbols across the reels, you’ll trigger a bonus feature that lures you deeper underwater. There, you’ll have your pick of chests to open and win a special prize. This is just one of the fun features of this game, which we’ll explore in greater detail shortly.
Mermaid’s Millions Theme, Symbols & Payouts
The graphics of the Mermaid’s Millions slot online might not be anything to write home about, but they don’t have to be. It’s a classic, simple slot that doesn’t need any bells or whistles to be appealing. The underwater theme is colourful, but not overwhelming or ostentatious.
| Best Mermaid’s Millions Symbols | Max Payout |
|---|---|
| Neptune | Up to 500x |
| Pearls | Up to 500x |
| Jewels | Up to 500x |
The mermaid symbol is the game’s Scatter symbol, whereas Neptune operates as the Wild. Neptune is the highest-paying symbol of the game, yielding 500x your bet if you manage to land five Wilds across the reels. The highest possible win in the game is 1,655x your bet.
If you manage to land 3-5 Scatter symbols, a free spins round is triggered. To claim the spins, however, you’ll have to win 4x, 50x or 400x your bet. Only 10 spins are awarded, but all payouts are tripled, making this a welcome boost to your winnings.
