Block or Allow sites with *Wildcards*
Depending on which Scene mode is selected, websites can be blocked or allowed using *wildcards*, another term for * (asterisks). To block by keyword, add a word with a * immediately before and after the word to your exceptions list. This feature is more useful when using allow mode, as you can block undesirable content by keyword.
When added as Block Mode Exception, this would block all websites, but allow all URLs that contain the word games.
When added as Allow Mode Exception, this would block all URLs that contain the word games.
The exceptions list only accepts secure URLs that start with https://. If you are trying to add an unsecured http URL, you'll need to add the URL with wildcards immediately before and after the URL.
