The Fire Link Feature is triggered by at least four Fireball symbols that lock in place and award three free spins. During the free spins, every new Fireball symbol locks in place and resets the free spins. When a set number of Fireballs are achieved, a new row is unlocked and added to the reels! Credit values and Progressive Jackpots are displayed on the Fireballs and increase in value as rows unlock. When no spins remain, the sum value of all locked Fireballs is awarded! In By the Bay, there is also a Free Games Bonus with expanded reels and Fireballs that award credit prizes!
