King Neptune is this mobile slot game’s wild symbol, which will help you make up your winning lines. Look out for 3 or more treasure bonus symbols on any one payline, as that will trigger the treasure bonus feature, awarding you with up to 2,500x your line bet.

The beautiful mermaid scatter symbol also has some prizes for you… get 3 or more of those symbols anywhere on your reels for 10 free spins with prizes tripled. Those free spins can also be re-triggered in this mobile slot so go for it!

This mobile casino game is lovely to play, with lots of color and a sense of undersea mystery to it, especially during the free spins feature with the sounds of the spinning reels and the mermaid’s teasing giggles. Slots online don’t come much more colorful than this, and combined with touchscreen technology, you’re only a tap away from taking a rich dip in Mermaids Millions!
