What is wrong with my code? The dialog box types out the wrong message.

I have this code

    var correctGuess = false;
    var randomNumber = Math.floor(Math.random() * 6) +1;
    var guess = prompt("I am thinking of a number between 1 and 6. What is it?");

    if (parseInt(guess) === randomNumber) {

        correctGuess = true;}

        else if (parseInt(guess) < randomNumber) {
            var guessMore = prompt("Try again! The value I am thinking of is lower than " + guess);
            if (parseInt(guessMore) === randomNumber ) { 
                correctGuess =true;}

        } else if (parseInt(guess) > randomNumber) {
            var guessLess = prompt("Try again! The number I am thinking of is smaller than " + guess);
            if (parseInt(guessLess) === randomNumber) {

                correctGuess = true; }
            }

        if ( correctGuess) {


            alert("Yey!");
        } else {
            alert("Better luck next time! The number was " + randomNumber);
        };

Although the code seems correct to me, it doesn't work as expected. Sometimes it displays messages like "Better luck next time! The number was 4", although the number I typed was 4. Or it asks for a smaller number, only to find out the result was bigger etc. Please helps.

Hi Arikaturika,

Ignore this answer, I overlooked the curly brace :) Your code works fine for me

You're missing a closing curly brace after the last else if. This code should work as expected:

    var correctGuess = false;
    var randomNumber = Math.floor(Math.random() * 6) +1;
    var guess = prompt("I am thinking of a number between 1 and 6. What is it?");

    if (parseInt(guess) === randomNumber) {

        correctGuess = true;}

        else if (parseInt(guess) < randomNumber) {
            var guessMore = prompt("Try again! The value I am thinking of is lower than " + guess);
            if (parseInt(guessMore) === randomNumber ) { 
                correctGuess =true;}

        } else if (parseInt(guess) > randomNumber) {
            var guessLess = prompt("Try again! The number I am thinking of is smaller than " + guess);
            if (parseInt(guessLess) === randomNumber) {

                correctGuess = true; }
            }
        }

        if ( correctGuess) {


            alert("Yey!");
        } else {
            alert("Better luck next time! The number was " + randomNumber);
        };

Best Regards, Philip

I tried your code, and it doesn't work at all. I have 4 curly braces on my last if else statement. So it must be something else :(.

When I test the code you posted in my browser, it works fine. Please try to reproduce the issue in another browser

I just did, using Firefox. Same issue, the alert box displays illogical results. Have you tried it a bunch of times, to make sure it doesn't give you an error? Most of the time the code works but one of let's say, 5 times, it doesn't.
