Как мне вернуться к основному методу?

---

я вложил в него свой код
вернуть;
но он не возвращается к основному методу

Что я уже пробовал:

import java.util.Random;     // Random number generator class
import java.util.Scanner;    // reads user inputs

public class HiLo
{
    private static Scanner input = new Scanner(System.in);
    public static void main (String[] args)
    {

        System.out.print("Rules");
        System.out.println("Number 1 through 6 are low");
        System.out.println("Number 7 are neither");
        System.out.println("Number 8 through 13 are high");
        System.out.println("You have 1000 points");
        number();
    }

    public static void number()
    {
        System.out.println("Predict(1=high, 0=low): ");
        int guess = input.nextInt();
        System.out.println("Enter the points to risk: ");
        int risk = input.nextInt();
        int points = 1000;
        switch(guess)
        {
            case 1: high(guess,risk,points); break;
            case 2: low(guess,risk,points); break;

        }
    }

    public static void high(int guess, int risk, int points)
    {
        final int max = 13;
        int answer;
        Random generator = new Random(); //Random  number generator. 0 to 10.
        answer = generator.nextInt(max) +1;

        if(guess!= answer)
        {
            System.out.println("Number is " + answer);
            System.out.println("you lose.");
            int total = points - risk;
            System.out.println("you have " + total + " points"); 
            System.out.println("play again?(1 for yes, 2 for no)");
            int playagain = input.nextInt();
            if(playagain == 1)
            {
                return;
            }
            if(playagain == 2)
            {
                System.out.println("GG");
            }
        }
        if(guess == answer)
        {
            System.out.println("Number is " + answer);
            System.out.println("you win.");
            int total = points + risk;
            System.out.println("you have " + total + "points"); 
            System.out.println("play again?(1 for yes, 2 for no)");
            int playagain = input.nextInt();
            if(playagain == 1)
            {
                return;
            }
            if(playagain == 2)
            {
                System.out.println("GG");
            }
        }
    }

    public static void low(int guess, int risk, int points)
    {
        final int max = 13;
        int answer;
        Random generator = new Random(); //Random  number generator. 0 to 10.
        answer = generator.nextInt(max) +1;
        if(guess!= answer)
        {
            System.out.println("Number is " + answer);
            System.out.println("you lose.");
            int total = points - risk;
            System.out.println("you have " + total + " points"); 
            System.out.println("play again?(1 for yes, 2 for no)");
            int playagain = input.nextInt();
            if(playagain == 1)
            {
                return;
            }
            if(playagain == 2)
            {
                System.out.println("GG");
            }
        }
        if(guess == answer)
        {

            System.out.println("you have " + total + "points"); 
            System.out.println("play again?(1 for yes, 2 for no)");
            int playagain = input.nextInt();
            if(playagain == 1)
            {
                return;
            }
            if(playagain == 2)
            {
                System.out.println("GG");
            }
        }
    }
}
