Думаю, программа количество

---

Проблема, с которой я сталкиваюсь, заключается в том, что переменная, которую я уже объявил сверху, не распознается снизу. Все переменные внизу, такие как numGames, totalGuesses, bestGuesses, которые я уже объявляю, не распознаются.
Я пишу этот код на java.


пакет guess2;

import java.util.*;
public class Guess2 {
    public static final int MAX_Number = 100;
    public static void main(String[] args) {
        
        Scanner console = new Scanner(System.in);
        giveIntro();
        int numGames = 0;
        int totalGuesses = 0;
        int bestGuesses = 9999;
        String again = "y";
        while (again.toUpperCase().startsWith("Y")) {
            int guesses = playGame(console);
            if (guesses < bestGuesses) {
                bestGuesses = guesses;
            }
            totalGuesses += guesses;
            numGames++;
            System.out.print("Do you want to play again? ");
            again = console.next();
        }
        reportResults();
    }

        
    
        
        
    
    //Introduces the game
    public static void giveIntro() {
        System.out.println("This program allows you to play a guessing game");
        System.out.println("I will think of a number between 1 and");
        System.out.println("100 and will allow you to guess until");
        System.out.println("you get it. For each guess, I will tell you");
        System.out.println("whether the right answer is higher or lower");
        System.out.println("than your guess");
    }
    
    //play one game with the user. return the number of guesses
    public static void playGame(){
        System.out.println("I'm thinking of a number between 1 and 100");
        System.out.println("Your guess?");
        Scanner console = new Scanner(System.in);
        int guess = 0;
        Random random = new Random();
        int answer = random.nextInt(MAX_Number);
        int numGuesses = 0;
        while (guess != answer) {
            numGuesses++;
        if (guess < answer) {
            System.out.println("the number is higher");
        if (guess > answer) {
            System.out.println("the number is lower");
        }
         
    }
    if (numGuesses == 1) {
        System.out.println("You got it right in 1 guess");
    } else {
        System.out.println("You got it right in "  + numGuesses + " guesses");
        
    }    
    return numGuesses;
        }
    public static void reportResults(){
        System.out.println("Overall result:");
        System.out.println("total games = " + numGames);
        System.out.println("total guesses = " + totalGuesses);
        double average = (double) totalGuesses / numGames;
        System.out.println("guesses/games = " + round1(average));
        System.out.println("best game = " + bestGuesses);
        
                
        
    }
}

Что я уже пробовал:

Я также пытаюсь выяснить, как вернуть значение для NumGuesses.
