77777 Jackpot

Bally Technologies introduced two new games that create a new dimension of visually stunning gaming action.  

The new Digital Tower Series of video and reel-spinning slots is unlike anything players have ever seen. With amazing top-box animation accompanied by dynamic sound effects, these towering new games command attention and dominate the slot floor.  

Debuting on this new Digital Tower Series platform are two remarkable new games: 77777 Jackpot and Fireball. These two new games are just the first of what promises to be a new generation of exciting Digital Tower stepper and video slots that will push the boundaries of gaming excitement and profitability to unheard of new heights.  

Accented with gleaming silver and chrome, 77777 Jackpot new stepper on Bally’s ALPHA Elite S9E base cabinet features a lucrative progressive jackpot, high hit frequency and a dramatic, sky-scraping, high-definition video top box ladder bonus that will attract attention from all areas of the casino floor.  

Reels spin. Lights flash. Music sounds. Excitement mounts. That’s the essence of gaming thrills created by the extraordinary 77777 Jackpot bonus. Triggered by three “77777 Jackpot” symbols on the middle three reels, the 77777 Jackpot bonus round features nine sets of three reels, with each reel representing a different level of the 77777 Jackpot progressive bonus ladder. Players watch in anticipation as the reels rapidly spin as they attempt to score as many different pay combinations as possible. Players have seven spins per level to hit the right target combinations that will catapult them upward toward the dazzling progressive jackpot. Plus! The game’s unique 32-inch vertical LCD top box adds even more drama and visual excitement to this remarkable gaming experience.


Dramatic, dominating and impressive, Fireball’s soaring top-box bonus tower takes gaming to new dimensions of blazing excitement with an array of dazzling digital effects, making this one of the most thrilling gaming devices you’ll ever see. Fireball is a five-reel, 40-line ALPHA Elite™ progressive video slot with a 2,000-credit max bet. One of Fireball’s signature features is an eight-level internal/external progressive with reset amounts ranging from a low of 10 credits to a high of 10,000 credits times the denomination.  

Fireball also gives players the opportunity to win exciting bonus rewards with two engaging secondary games: The Free Spin Bonus and the Triple Blazing Fireball Bonus. Three “Scatter” symbols on reels two, three and four award players 10 free spins. These free spins can be re-initiated during the bonus if the same Scatter symbols appear, awarding players an additional 10 free spins.  

The explosive Triple Blazing Fireball ‘Game-In-Game’ bonus event begins when from three to eight Fireball symbols appear on any of the reels. The Game-In-Games are played randomly from the existing eight Fireball symbols, depending on the number of Scatter symbols.
