Way harder than https://www.jetpunk.com/user-quizzes/2180195/most-guessed-cities-by-us-state-1 (not that that's a bad thing). Would've still gotten at least 4/5 for every state if I had tried spelling Elizabeth with a z instead of an s.
13/40 - I know all the capitals and I do know quite a lot of US cities - at least I thought, and not from most of these states. Alaska was my best state at 3 cities named.
Oh, I actually knew Boulder and Aurora but for some reason I never thought of it during the quiz. I got one full state, which was Alaska. My rarest guess was Elizabeth with 23% guess rate, but that was because I've been there.
Olympia isn't nearly as big as any of the other 4 cities in Washington on the list. Maybe it's guessed because it's the capital? I tried Yakima, Kennewick, Everett, Kent and Bellevue before I tried Olympia
