Hot Hit Rainbow Riches

This new five-reel, 30-line game in the mechanical reel-spinning format offers nine frequently hitting progressive jackpot levels, along with a free-spin bonus and a unique primary-game feature that causes variable jackpots for the same winning combinations.

The Hot Hit progressive series returns a progressive prize any time  “Hot Hit” symbols land on seven or more spots of the 15-space reel grid. Progressives start at a reset level of $15 for landing seven of the symbols, ascending to the top jackpot, starting at $15,000, for Hot Hit symbols in all 15 reel spots. Players must wager the maximum to qualify for the top jackpot.

The progressive setup—a celebration of horns, sirens and buzzers greets each jackpot—is not the most unique aspect of the primary game, though. The base game features a weighted pay table in which symbols change color on every spin. Different colors award different payouts, with red awarding the highest, followed by blue, green, purple and yellow.

Added to this unique feature is a free-spin bonus, triggered by three scattered bonus symbols. During the free-spin bonus, solid-colored symbols evolve into rainbow symbols for higher awards.
