I gave up at "Mark all squares of the 64th floor of the Empire State Building"[1]. I had even spent an hour on the chess challenge, but that one looked tasteless if I wasn't missing a trick. I thought that I was supposed to try all the floors close to 64 (considering the topmost one below the tower was 86). I really didn't have the patience for that, especially the possibility of missing to mark an overflowing pixel line, etc.

Also, I hit a bug at the AI challenge which prevented me to pass it. So I had to spent at least 5-6 more tries to pass it.[2]

Fun, but wouldn't go near it again :)

I reverse engineered what I could, and it's supposed to be all in row 30, column 4 to 11 (8 squares). You may add 2 more squares on the left or right side (it's just checking it's no more than 10 squares).

It's the third row where other buildings show up.

I googled an image found out how many floors it has and counted down from the top. worked on second try after I realized that many squares contain two floors

They gave me 2 queens to start with on my second attempt

I just had deep blue play against stockfish since I wasn't that good at chess.

Yeah, you just try every floor close to 64. It took me like a minute or two to click through.

I found a diagram that listed the 71st floor. I went down a bit and bruteforced a search.
