why I can not block this game website?

Question

At Web Filter Profiles | Block these websites , I use following string in Regular Expression and Domain: 
 1) ^https?://([A-Za-z0-9.-]*\.)?.poki.com/ 
 2) poki.com 
 But the user still can entry this website, how to solve this problem?

I am guessing that the parenthesis are producing unexpected results. RegEx is more fun than crossword puzzles, but rarely necessary in UTM. There is a much easier solution. 
 Create a Websites object for poki.com and check the option to include subdomains. Then either give it a blocked category, blocked reputation, or make up a tag. If you use the tag, then add a tag rule for block to the Filter Actions. I prefer the tag approach because I can choose a tag name that documents my purpose.
