If 8 or more Giftbox symbols are cleared in a single spin or during Free Spins through the Cascading Effect, a Jackpot is awarded based on the total cleared: 8 for Mini, 10 for Minor, 15 for Major, and 20 or more for the Grand. Only one Jackpot can be won per spin or feature. During the feature, additional rows unlock when 4, 6, or 8 Giftboxes are cleared, opening rows 4, 5, and 6, respectively.
