  • You could also unlock the bonus features by landing scatter symbols or wilds.

What Symbols Trigger the Lucky Koi Slots Bonus Free Spins?

Attaining three or more scatter symbols allows you two options- you can either opt for free spins or go fish in the koi pond.

The number of free spins ranges from 10 to 30, and up to 5x in winnings.

For those opting to fish for Koi, you can have different rates of earning. This depends on the Koi that you catch out of the pond.
