Greek here, the reason why you didn't recognise the Greek flag is because that we started using our current flag 🇬🇷 in 1974 which was the year when the Greek right wing military dictatorship fell after controlling the country for 7 years and btw we have been a republic 3 times throughout our modern history
For GeoGrid, it showed the most common and rarest answers, not just correct ones that would have worked in an individual game. Also any country ending with "-land" (Poland, Finland, Iceland, Ireland) + Chad would have worked for the second column
Dido actually the flag of Greece you saw in the timeguessr was the flag we used before the new and improved version we use today, also love your videos (big fan).
I LOVE THEM! They're a good fit and stay true to size. Make sure to tie them tight tho as I find the laces and traction a little slippery but that could be because they're still new
Fun fact. Never ask a person in Switzerland who is younger then 23 about geography. I don't like geography but at least I knew that Sweden wasn't Switzerland.
