Got 200 but got also bored. Skipped all the US cities after Chicago. I think you have a typo at least with Almaty and Phoenix. You have some great type-ins but why do Tainan, Cebu, Benin need 'City' to be accepted?
There are a few misspelled city names: Phoenix, Tabriz, Havana, Rabat. Please check your spelling - some of the harder ones I may have missed. Fun and challenging quiz.
Good quiz. Big metros split and many small cities appear. But simpler answers should be accepted, e.g. Basra (Iraq) instead of Al Basra al Qadimah. Also some spellings are either wrong or unpopular, e.g. "Sozhou"? Suzhou should be correct. "Nanchong" - does it mean Nanchang or Nantong?
