So I posed the question to firstname.lastname@example.org. Unfortunately, the answer was not what I was looking for.
My question to Pet Rescue support:
On the Pet Rescue Saga FAQ (
http://about.king.com/games/pet-rescue-saga/faq ), I see that it is
possible to play all levels of the game without connecting to
Facebook. After level 27, however, I am being asked to connect to
Facebook, and cannot seem to get around it.
Is it possible to play all of the levels of Pet Rescue Saga without
connecting to Facebook? If so, how? If not, you should probably
update your FAQ because it is quite deceiving.
Scanning through the long generic reply, the following statement answers the question.
Every few levels (starting with level 27), you have to unlock a new
episode, in order to continue playing. This can be done by either
asking 3 friends for help when connecting with Facebook or by paying
for the ticket.
So the FAQ statement on the Pet Rescue FAQ is a bit vague, probably on purpose. Yes, it is possible to play the full game without connection to Facebook, however, it comes at a price.
