The original stacked-wild wolf game — up to 255 free spins
The howling-wolf wild lands in full-reel stacks — rare, but two or three stacked reels at once is where the game's famous wins come from.
Three bonus symbols across reels 2, 3 and 4 award 5 free games at the triggering bet.
The feature retriggers whenever the bonus symbols return, with a ceiling of 255 spins in one run.
Five wolf symbols in sequence pay the game's 1,000-credit top line prize.
Bets range from a penny up to 5 per line, with as many as 5 coins per payline.
Up to 40 lines are available across the 5 reels — max lines means maximum action from every stacked wild.
Bonus symbols only count on reels 2, 3 and 4, so that is where the free games are won.
Full reels of howling wolves are the event that turns an ordinary session into a big one.
When Wolf Run first reached casino floors, its stacked wilds were the talking point: the howling wolf arrives in vertical stacks that can blanket an entire reel, and on a 40-line game a couple of wild reels landing together produces the kind of screen-shaking payout that built the machine's reputation. Pair that with a free-spin bonus that retriggers up to 255 spins, and you have a formula IGT later spun into sequels like Wolf Run 2 and Wild Wolf.
Every slot family has a founder, and for IGT’s wolf games it is Wolf Run. Built on the imagery of the wolf as an ancestral creature in Native-American tradition — starry night skies, a bright moon, a howling silhouette — the game paired restrained graphics and minimalist music with one killer mechanic: wilds stacked deep enough to swallow whole reels. It became a floor legend, and its DNA runs through Wolf Run 2: Into the Wild, Wolf Run Party and the popular Wild Wolf sequel.
On paper it is a high-variance 5-reel, 40-line game with a 94.9% return, penny-to-5 line bets, a 5-spin bonus that can retrigger all the way to 255 free games, and a 1,000-credit prize for five wolves. Expect long quiet spells — then two, three or even four stacked wild reels in one spin, and fireworks.
