This doesn't split the word up into individual letters - you need
@word=word.split(//) for that AFAIK.

Why are you storing the guesses and the bad guesses and the good
guesses?  You're at least storing things twice here!

A single hash of guesses, where good guesses map to true and bad
guesses map to false is probably better.

attr_accessor :word at the top of the class def is more idiomatic.
For that matter, so i leaving off the empty () for method calls

this could be written much more simply as

def lost?
  bad_guess_count == MAX_GUESSES
end

though you might find

def lost?
  return bad_guess_count == MAX_GUESSES
end

more readable
