Hopefully this will work for whoever else had the same problems. I had to resolve both "cannot find symbol" and "NoSuchElement" issues on my workspace. I spell-checked my Game.java file, no errors. I made sure the line "return isHit" was placed correctly as i misplaced it at first. Then I slowly typed my commands in the java-repl, checking that i'm using proper quote symbols on each line. I'm not 100% sure how i finally resolved the "cannot find symbol" error. It was very pesky. But hopefully my code here works for at least one other user -.-'"

It's probably because of missing braces

Try this code:

public class Game{
  private String mAnswer;
 private String mHits;
private String mMisses;

    public Game(String answer) {
   mAnswer = answer;
      mHits = "";
      mMisses = "";
  }
  public boolean applyGuess(char letter) {
    boolean isHit = mAnswer.indexOf(letter) >= 0;
    if (isHit) {
      mHits += letter;
      return isHit;
    } else {
      mMisses += letter;
     }
}

}
