If it’s been incremented by $50, the 1x bet would be $1,050 and the 5x bet would be $5,050. The progressive changes with bet it consists of $1,000 times the line multiplier, plus whatever amount the progressive has been increment. (Wilds can only appear on the middle three reels). The first is a progressive, that is awarded if all 15 spaces on the middle three reels are wild.
The Gold Bet gives you access to two additional features not present on the original game. The original had an unusual 5-5-3-5-5 reel set, whereas this is a more simplified 5×5 reel set. It is effectively a more/better bet even thought the reel set is different on this game vs. This version gives you a few choices, either 50, 75 or 100, and adds a Gold Bet for 25 additional credits that activates progressives and random wilds. The original game had 100 lines and in most cases (depending on casino configuration) let you decide how many lines you wanted to play. But with Stinkin’ Rich Skunks Gone Wild, they’ve developed a successor that’s worthy of the brand, without tinkering too much with what made the original successful. Given the enduring popularity of Stinkin’ Rich and its clones over the years, it’s a bit of a surprise IGT hasn’t tapped the game for sequels more than it has.
