The Blob

This game on the Bally V27/27 cabinet is a nod to the 1958 science fiction classic The Blob, in which a giant, growing amoeba from outer space feasts on the citizens of Downingtown, Pennsylvania. The reel symbols include both film-specific images and more general examples of terrified citizens and other icons of cheesy ’50s sci-fi flicks.

The base game is a 243-ways-to-win penny video slot featuring a five-level progressive jackpot. The top jackpot is a wide-area progressive in the Bally Cash Connection link, resetting at $1 million.

The progressives are won through a comparatively frequent bonus event. The Jackpot Bonus is a mystery event, triggered randomly every 86 spins on average on either a primary-game or free spin. The player picks from a field of 15 meteors until matching three. The player wins the jackpot matching the color of the three meteors, with prizes ranging from a reset of $10 for the Mini to $5,000 for the Grand.

If three matching star symbols are revealed during the bonus, the wide-area “Box Office Jackpot” is awarded. Max bet is required for the top progressive.

There are two different themed free-spin features, and the player chooses which one when triggering the “U-Choose Free Games Feature.” Three or more scattered Blob symbols award 10 free games, the player choosing between “The Blob Devoured the Royals” and “Wild Stacks.”

In the former, all royal symbols are removed from the reels, increasing the chances for top-tier five-of-a-kind jackpots. In the latter, three of the same active symbols on a reel become wild, creating a wild reel. Each of the free game events is retriggered for an additional 10 games if three Blob symbols land.
