From what I can see, the daily challenge should be the same for everyone.You probably can't find that on a lot of maps due to what it is. What is strange is that wasn't any of my answers. @Pifanjr was that in your daily?
I guess in time we will be able to narrow it down fast. Probably not as fast as this guyI only got 9000, partly because on the third location I was on a small street in the middle of nowhere with no signs, cars or buildings. I ended up picking somewhere in the US midwest only because the landscape was flat. I got 100 points. But I'm generally bad at geography, anyway. Still had fun though.
