20 errors... after adding these changes can't find symbols for any of my methods.

Not sure how prompter seems to be missing all methods of mGame. Is there something in my code that decoupled prompter from game class?

//Prompter.java

import java.io.Console;

public class Prompter {
  private Game mGame;

  public Prompter(Game game) {
  mGame = game;
  }

  public void play() {
    while (mGame.getRemainingTries() > 0) {
      displayProgress();
      promptForGuess();
    }
  }

  public boolean promptForGuess() {
    Console console = System.console();
    boolean isHit = false;
    boolean isValidGuess = false;
    while (! isValidGuess) {
       String guessAsString = console.readLine("Enter a letter:  ");
       char guess = guessAsString.charAt(0);
       try {
        isHit =  mGame.applyGuess(guess);
        isValidGuess = true;
      } catch (IllegalArgumentException iae) {
        console.printf("%s. Please try again. \n", iae.getMessage());
      }
    }
    return isHit;
  }

  public void displayProgress() {
    System.out.printf("You have %d tries left to solve: Try to solve: %s\n", 
                      mGame.getRemainingTries(),
                      mGame.getCurrentProgress());
  }
}

Found it! Looks like I was missing a close } at the end of my validateGuess() method.

I exported the text into Atom and once in there I could see that all of my methods further down had goofy syntax highlighting.

Oh syntax highlighting! I rely on it too much to know what's wrong!

Just a little something... In your contructor, try to indent mGame = game; It seems you can't access the game object, so I guess something is wrong when you assign game to mGame.

Hrm... Didn't help. I don't think java cares about white space (either horizontal or vertical). Thanks for the suggestion though.
