Why is my Random number staying the same in Java?

my question; why is my Java code outputting a 'random' number, as the same? - Almost like the random gets stored into the variable.

I am creating a basic higher or lower game, of which displays a card number, and user has to choose whether he/she wants to go higher or lower.

Here is my written code:

String guess;
    String choice;
    String choice2;
    String sameChoice;
    String sameChoice2;

    boolean correctGuess = true;
    boolean replay = true;

        Random rand = new Random();
        Scanner scan = new Scanner(System.in);

        byte card = (byte) (rand.nextInt(13 - 0) + 1); 
        byte card2 = (byte) (rand.nextInt(13 - 0) + 1);
        byte card3 = (byte) (rand.nextInt(13 - 0) + 1);

        while (replay) {

        System.out.println("Card is: " + card);
        do {
        System.out.printf("(H)igher or (L)ower: ");
        guess = scan.nextLine();

        if(guess.equals("H") || guess.equals("h")) {
            System.out.println("Card is: " + card2);
            if(card2 < card) {
                System.out.printf("Card is lower, you lose - play again? Y/N : ");
                choice = scan.nextLine();
                if(choice.equals("Y") || choice.equals("y")) {
                    replay = true;
                    break;
                }
                else if(choice.equals("N") || choice.equals("n")) {
                    System.out.println("\nThank you for playing.");
                    replay = false;
                    break;
                }
            }
            else if(card2 == card) {
                System.out.printf("Numbers are the same, draw! - would you like to play again? Y/N : ");
                sameChoice = scan.nextLine();
                if(sameChoice.equals("Y") || sameChoice.equals("y")) {
                    correctGuess = false;
                    replay = true;
                    break;
                }
                else if(sameChoice.equals("N") || sameChoice.equals("n")) {
                    System.out.println("\nThank you for playing.");
                    replay = false;
                    break;
                }
            }
            else if(card2 > card) {
                correctGuess = true;
                replay = false;
                continue;
            }
        }
        else if(guess.equals("L") || guess.equals("l")) {
            System.out.println("Card is: " + card3);
            if(card3 > card) {
                System.out.printf("Card is higher, you lose - play again? Y/N : ");
                choice2 = scan.nextLine();
                if(choice2.equals("Y") || choice2.equals("y")) {
                    correctGuess = false;
                    replay = true;
                    break;
                }
                else if(choice2.equals("N") || choice2.equals("n")) {
                    System.out.println("\nThank you for playing.");
                    replay = false;
                    break;
                }
            }
            else if(card3 == card) {
                System.out.printf("Numbers are the same, draw! - would you like to play again? Y/N : ");
                sameChoice2 = scan.nextLine();
                if(sameChoice2.equals("Y") || sameChoice2.equals("y")) {
                    correctGuess = false;
                    replay = true;
                    break;
                }
                else if(sameChoice2.equals("N") || sameChoice2.equals("n")) {
                    System.out.println("\nThank you for playing.");
                    replay = false;
                    break;
                }
            }
            else if(card3 < card) {
                correctGuess = true;
                replay = false;
                continue; 
            }
        }
        scan.close();
    } while(correctGuess);

The output of this comes out like this:

Card is: 3
(H)igher or (L)ower: h
Card is: 11
(H)igher or (L)ower: h
Card is: 11
(H)igher or (L)ower: h
Card is: 11
(H)igher or (L)ower: h
Card is: 11
(H)igher or (L)ower: h
Card is: 11
(H)igher or (L)ower: 

As you can see, whenever i wanted to choose "Higher" It just repeats '11' even though my random generator is limited to 13.

Thank you.
