To activate the Giga Jar Feature, look to land a Gold Vinyl Symbol after the Giga Jar has reached its max level. Once it's triggered, this feature will get rid of all existing symbols, and will replace them with blocks of Instant Prize Symbols. These could come in the form of 2x2 3x3 or 4x4. From here, you'll be given 8 free spins to use in the hopes of landing additional Instant Prize Symbols. Each time you’re successful, you’ll bag yourself an additional 1 or 2 free spins.
