Correct. I finally looked at code (ctrl+u). It had an Iframe to site you mentioned. I changed my link to the inner link and it works fine now. I assume code was move/duplicated and the Iframe substituted causing the problem. I will try to contact the website and make suggestion for better fix.
You can possibly create a cookie allow exception for https://websudoku.com/ to see if that has effect.
