Button to Start Over a Survey

We have created a raffle form that we will be loading onto a few tablets at an upcoming community fair. 

At the end of the survey, is there a way to add a button to “start over” or reset the form that brings you back to the beginning of the form?

I found a previous Q&A that states that “By default, your Ending screen has a button that will restart your typeform, but you can toggle this on and off, and also change the text/hyperlink of the button.” However, I have been testing out what I think is the correct button but it brings me to the Typeform promo page. 

Thanks!
