You're standing somewhere on the island. Read the hills, the coast and the snow lines, then find your spot on the map.
POV Guesser drops you somewhere on an island and shows you the view. Work out where you are from what you can see (the shape of the hills, the line of the coast, where the snow starts), then mark your spot on the map.
A new challenge comes out every day, so there's always a fresh view to read.
