Like most Facebook games, there are no 'cheats' for Pet Rescue Saga. Instead, you are better off perfecting your strategy and using the video walkthroughs and following the Hints and Tips
outlined below. As the game runs off Facebook Credits, the developers are always very careful to ensure this ecosystem is protected.
As such there is no cheating way to get Facebook Credits, you have to pay for them or earn them by looking out for various offers while browsing the website. You should be sure not to give out your Facebook account details, as these are one of the ways people hack accounts - by pretending they can give you free credits when in fact they are looking to compromize your account.
Feel free to post any cheats, hints or tips in the comments though and we can add them to the guide if legitimate exploits become available!
