There was one for fishdom, says to complete the tutorial. 6 nobs but only took me 3 minutes. I think the link went away when I completed it
Ive spent hours trying them and only had a 10 nob one work one time. The website is honestly a scam. I am glad i gave them a spam email account otherwise I would have to deal with their trash on a real email account.
There are a few right now that work. The I got nobs from Coin Dozer offer, Gardenscapes offer, and Fishdom offer.
