Has anyone gotten this achievement? If so, how many stickers do you have in your collection, unique and overall count? I'm trying to do this achievement but I want to know if there's a magic number or if I need every single sticker ever made, including collection stickers. Maybe I just need to finish the sticker sets achievements that are listed under the stickers section in the achievements. Not sure. Please help.

If you mean the "Sticker Master" achievement you need to have every single sticker in existence, yes, including the cash shop collection stickers.

There are 1736 unique stickers on site. The overall number doesn't matter, only the unique.

Ok. Thank you. I guess I better get working on updating my wishlist. Only 730 stickers to go. :(
