[Number Game] A Real Challenge

This game would be easier if you could guess the same number twice in a turn. . . The original puzzle statement seemed to allow it, and I was confident in my answer until I found out that the 4 numbers guessed in each turn had to be distinct!

I found a nice solution, which was probably intended, after asking my questions yesterday. Tough one, though.
