193, I missed three in Central America/Caribbean... I'm curious, what did you miss and what's your 'technique'? I do one continent at the time, moving around neighbouring countries. By the way, thanks again for suggesting to make this quiz!
I just worked my way steadily around each continent, and just made mostly sloppy mistakes here and there. The only one I forgot the name of despite seeing its location in my mind was Malabo (a minute on "what's the capital of EG?" without success); I felt uneasy like I hadn't got all the Caribbean and Pacific ones, and I missed one in each, Funafuti and Basseterre; the other 7 were just careless misses: Accra, Addis Ababa, Algiers, Asunción, San Salvador, Windhoek and Yaoundé.
i only missed 2 but they were super easy obvious ones. I find that i often miss the obvious ones, because my brain is trying to focus on the harder ones. I missed Manila (where my husband is from) and Mexico city...duh.
Managed it with 10:26 left.
