Hi Sara,
If you go to alljackpotjoy.com, scroll down a little bit, there is a banner that points to Jackpotjoy. The aff tag is masked, but if you click on the banner anyway, you’re taken to xhttp://static.jackpotjoy.com/upload/design/bingo/
From there, I’m not exactly sure how to determine the affiliate tag. I viewed the source code and pulled “UA-784066-1 ” from a piece of javascript in the source.
