Try maintaining the word as an array. Here's a basic sketch:

class Hangman
  def initialize(word)
    @word = word.split //
    @good_guesses = {}
  end

  def display_word
    @word.map {|i| @good_guesses[i] ? i : "_"}.join(" ")
  end

  def guess(letter)
    if @word.include? letter
      @good_guesses[letter] = true
    end
  end
end
