The Ultimate Fire Link^® series showcases fast-paced, progressive games that give players a heart-pounding slot experience. They are built around an action-packed bonus mechanic, the Fire Link Feature^® which is a lock-and-spin feature that builds anticipation and breathtaking excitement with every fireball that lands on the reels.

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 achieved on the reels locks in place and resets the Free Spins available to three. 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 as rows unlock the credit values and jackpot levels increase. When no spins remain, the sum value of all locked Fireballs is awarded!
