How To Play

Expanding Wilds

Whenever at least one wild symbol hits, all wilds on screen have a chance to randomly expand towards top-left, top-right, down-left or down-right in a square of 1x1 to 5x5. They replace symbols on the screen with more wilds.

Free Spins

Hit 3 free spin symbols to trigger the free spins feature. The round starts with 6 free spins.

Gold Nugget

The Gold Nugget symbol only appears during the free spins round. Whenever the Gold Nugget symbol hits anywhere on screen, it is accumulated in a meter used for the progressive feature and then it explodes. The remaining symbols fall to the bottom of the screen and the empty positions are replaced with symbols coming from above.
