Ultra Stack Mermaid Slot Video - RETRIGGER FRENZY!
The Ultra Stack Mermaid slot machine by Aruze is unique!
And this time, they've added a fun new feature: the "Chance for Repeating Retrigger" which allows you to hit the spin button to possibly retrigger your bonus although how you press the button has absolutely no effect on whether you'll get the retrigger or not! Like Ultra Stack Lion, you trigger the bonus by getting bonus symbols on reels 2, 3, and 4 and you then choose a pearl to determine which premium symbol will be increased during your free games.
After your 6 free games are completed you can play this "Chance for Retrigger" game by hitting the button rapidly although it's all for show as there's no "skill" involved in this feature, Enjoy!
