Twenty lines, five reels, and a very good idea
The Dog House is a five-reel, three-row machine with twenty fixed paylines and a cast of cartoon dogs: a pug, a dachshund, a poodle, a chihuahua and a rather smug-looking terrier, backed by the usual card values. Wins pay left to right from the first reel across adjacent reels, which is about as traditional as modern slot design gets.
It would be entirely unremarkable, and there are a thousand games like it gathering dust in every lobby, were it not for a single mechanic that the studio got exactly right. That mechanic is the sticky multiplier wild, and it is one of the cleanest, most elegant ideas in the whole Pragmatic catalogue. Everything worth saying about this game comes back to that wild. It shapes the base game, it defines the bonus round, and it explains precisely why this ostensibly modest twenty-line slot has a ceiling that embarrasses machines with far more elaborate feature sets. Understanding the wild is understanding The Dog House.
