The Babbel one gave me California, too. It seemed to be mostly about pronunciations, and less about word choice for things, which might be why.
The Buzzfeed one correctly gave me Wisconsin, but I chose “bubbler” in that one. 
Yeah, I saw the “bubbler” one and I was like, well, that’s gonna nail a very specific subset of people taking the test. 
ETA: The New York Times quiz got me a lot closer, with Madison, Milwaukee, and Rockford. It should have included a question about the word “jagoff” and it would have fixed me more towards Chicago (or Pittsburgh, though my other answers would clearly move it away from that.) And add a question about the main room where people gather in a house. (A “front room” or “frunchroom” for us Chicagoans.)
Babbel placed me in: the Midwest, “a pretty big swath of the United States.” I’m unimpressed.
Buzzfeed failed to give me any answer; it cut off before it was completed. Notice the vast majority of visitors rated it “Fail.”
It brought back a long-forgotten memory from early childhood: I remember somebody local pronouncing it “wheelbarrel,” and I wondered why, since it wasn’t written that way. It’s probably quite old. I haven’t heard it since the 1960s.
Yes. I can remember my grandmother saying “warsh” (central Ohio), but my dad (now in his 80s) never did.
In East Tennessee it was “worsh”. I never picked it up, and don’t remember hearing it until I started school.
“Wheel barrel” is still a common pronunciation of wheelbarrow in SE Louisiana. It’s part of my own idiolect for sure.
I do remember saying that as a kid in Chicago, but I suspect it was my own eggcorn and not local dialect.
Come to think of it, it might have been just me.
One of those quizzes asked me what I called a sub. When I answered hoagie, that narrows it down to Philadelphia or surroundings. I still recall that once we drove to Atlantic City and my father warned me that they called hoagies subs there. I was probably 8,
