Where can I go to get free facebook or zynga credits?

There are a few sites you can try:

http://fanup.com
http://gamesophosly
http://www.gamecoins.com

Use 4loot because your se I were able to be able to exchange coins we have won for searching towards 15 credits so far.You never always win however the more people search a lot more you win.Just head over to 4loot in addition to link it to you FB account

you can get Free ‘tokens’ by connecting to some adventures but in addition to that you must buy credit.
