This method works with IE and Firefox.
Important: I'm doing it with IE but you can follow the same steps to do it with Firefox!
Here we go:
1) Open IE and go to this link :
2) It's an official Zynga Game Bar. Download it and install it. (It's adware and spyware FREE!)
3) Once you are done installing you'll see this bar:
4) Now click on the 'facebook icon' on the toolbar and you'll get this:
5) Login using your account.
6) Once you login the toolbar kind of refreshed in 5-10 seconds and you see a green 'play now' button.
7) Click that. It'll take you to the Zynga App.
You'll now get $25k, click on the green 'Accept $25k' button :
9) Now close IE (just from the close button)
10) Open IE again. Now click the 'facebook icon' again and it'll again ask you for a login.
11) Now enter a different account and repeat steps 4-8.
12) You'll get 25k AGAIN!
13) You can do this with UNLIMITED accounts and then keep transferring chips to one account.
