If you’re a super savvy streamer, you may already be well-versed in the game of Netflix genre-hacking. If not, here’s a little trick you can try at home to make being a couch potato even easier!

Reporters over at Gizmodo and The Atlantic mention this is isn’t necessarily anything new, but in case you weren’t already aware, there’s more than meets the eye on those Netflix genre pages. For example, if you’re browsing, say Classics, there’s a link that populates in your browser that looks something like this:

http://www.netflix.com/browse/genre/31574

Those last five numbers, 31574, indicate Classics to Netflix engineers who build out these pages. And while that’s great and all, there are only a finite amount of genres and subgenres (Classic Thrillers, for instance) made visible to the average streamer — until now! By manipulating those last five digits in the link, you can search for more specific genres and subgenres that suit your mood.

Gizmodo tracked down a massive list that has since been disabled, but here’s one that lists all major alternative genres. Just a forewarning that not every number combination will work because of Netflix’s vast sea of ever-shifting movies and shows. But how cool is it that you can track down Comic Book and Superhero Movies, Movies for Ages 8-10, Film Noir (I will definitely be using this one), or Horror Comedy in one click?

The question, however, isn’t, “Where has this been all my streaming life?” But rather, why doesn’t Netflix just make this kind of access available without jumping through any hoops? Perhaps it’s just one of the many things they enjoy, as the most elusive streaming service around, keeping close to the vest.
