        for (int i = 0; i < NUM_SLOTS; i++) {
            result[i] = SYMBOLS[(int) (Math.random() * SYMBOLS.length)];
        }

        // Display the result
        System.out.println("Spinning...");
        for (String symbol : result) {
            System.out.print(symbol + " ");
        }
        System.out.println();

        // Check for a win
        if (result[0].equals(result[1]) && result[1].equals(result[2])) {
            System.out.println("Jackpot! You win!");
        } else {
            System.out.println("Sorry, better luck next time.");
        }

        // Ask if the player wants to play again
        return askToPlayAgain();
    }

    // Method to ask if the player wants to play again
    private static boolean askToPlayAgain() {
        System.out.print("Do you want to play again? (yes/no): ");
        Scanner scanner = new Scanner(System.in);
