About Coin Volcano
A distant island and its giant volcano set the scene for this compact 3 × 3 coin collector from 3 Oaks. The middle row is where everything starts, so that's the line to keep your eyes on during every spin.
Inside Coin Volcano
Middle-row trigger
Three symbols on the middle row start the bonus with three respins. A Sticky Coin stays locked until respins trigger, and the Volcano Meter fills with each symbol on an active line, starting the bonus when full.
What lands in the respins
Bonus symbols bring values, and Mini, Minor and Major jackpots can land. A Mystery Jackpot symbol reveals one of those, a Mystery symbol turns into anything but the Sticky Coin, and Collect gathers every coin value.
Eruptions and Ultra Bonus
The Volcano Multiplier feature can switch on at random during respins, placing one to nine multipliers across the reels. The Ultra Bonus Game also triggers at random and always opens with that feature active.
Coin Volcano questions
Is there a prize for covering all nine spots?
Yes. Filling the entire grid during the respins may award the Grand Jackpot, which sits above Mini, Minor and Major.
