Good morning on this gray Thursday.

We’re a city filled with HQties.

That’s the nickname given to those who play HQ, the wildly popular trivia smartphone app that has been called “the best worst thing on the internet.”

Twice daily, at 3 and 9 p.m. on weekdays (and once daily on weekends), as many as 1.6 million HQties across the country open the app for a live, 15-minute trivia run with the host Scott Rogowsky. Contestants who make it through all 12 questions — which become increasingly obscure and move so quickly that it’s nearly impossible to Google the answers — can win cash prizes.

Some might be surprised to learn that the retro-themed trivia game, which resembles a ’90s cartoon mixed with a scene from “Alice in Wonderland,” is actually filmed at a studio in SoHo. Another possible shock: Mr. Rogowsky, 33, who goes by Quiz Daddy on the app and now has a following across the globe, is from New York and was, until recently, a struggling comedian here.

We asked HQ’s writing team to put New York Today readers to the test with some questions about the state we call home.
