Interesting - they added an "every state" feature to the game. It's an interesting way to find out how many states have a place with a given name, but IMO it feels like cheating.
Well, I mean, some degree of that happens if you don't have that feature turned on. I was going through and entering Oklahoma county seats that I remembered, and when I entered "Beaver" it matched to Beaver PA instead of Beaver OK. Had no idea there was a Beaver PA before that.
And for me, the opposite would've happened: I type in Beaver for PA, it populates, and I never learn about Beaver, OK.
To me, the reason it might be considered cheating is when more than two cities are involved, so you get a
bunch of bonus cities, not just one. Beaver is actually an example because there's at least a Beaver, UT, and possibly others. Springfield is one of the most prominent ones, with the cities in IL, MA, and MO being well-known, plus lesser-known examples in dozens of other states including NJ, NY, OH, and PA.
