Anything look strange about this line to you?

private Game mgame;

HINT: Case matters in Java

Did you set mGame in the Prompter constructor? Might help to share your code?

// Hi Craig, here are from prompter. I cannot find the error, still.

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 this: %s\n", 
                     mGame.getRemainingTries(),
                     mGame.getCurrentProgress());
  }
}

Awesome, eye of an eagle you have Craig. Many thanks.
