Feature Request - Required Field which can enable Submit Button

I'm trying to have a question to prevent spam on my site. The question will be "What day comes after Saturday". If the answer is Sunday I want the submit button to work. But I do NOT want to hide the Submit at all on my form. I want it always visible just if the answer is wrong it won't submit it.

Here is the form, again I do not want the submit button hidden at all. 

To my knowledge the only way this would be possible is via conditional logic. But the problem with that is that it would hide the submit button which stated you didn't want to happen. 

So I've sent this to our development team as a feature request on your behalf. I think this would be a great concept to have within the existing " Requirement Condition" to allow submit to work.

Here's a demographic screenshot of what I am envisioning for what you mentioned.

I don't think there is any need for such a feature. The conditions can already handle this. You can hide the submit button until the question is entered.

Also, you do not need such a captcha. We already have a way to detect spam. You should not get any spam.

We do also have captcha options in our form builder, even though it is not needed, just because users ask it a lot.
