BTW, you forgot to close the file. Although that doesn't matter in a 
short-lived script, there is a way of avoiding this problem:

  File.open("guess.txt") do |file|
    $guess = file.gets
  end

This opens the file, runs the block, and then closes the file (even if 
the block aborted with an exception rather than completing successfully)

BTW, local variables which are first seen within a block are private to 
that block, so if you want do use a local variable do this:

  guess = nil
  File.open("guess.txt") do |file|
    guess = file.gets
  end
  ... now 'guess' contains the result of reading the 1st line of file
