Zynga recently launched Castleville, but now the social gaming giant appears to have plans to launch a new game called Forestville.

This week Zynga registered several domains with the word Forestville in the name like ForestvillewithFriends.com and ForestvilleZynga.com.

All of the names were registered through the internet brand protection company MarkMonitor that Zynga regularly uses to acquire domain names.

Interestingly enough, Zynga doesn't own the prime internet real estate: Forestville.com.  The domain is currently home to the Forestville Central School District website out of New York.  But that hasn't stopped

Zynga from registering typos of Forestville.com like wwwforestville.com (minus a ' ') or forestvile.com (minus an ‘l’).

Zynga did manage to get several country domains like Forestville.de, Forestville.jp and Forestville.co.uk.  A message on the home page of Forestville.de reads, "This domain is registered and protected by MarkMonitor".

Right is a list of many of the names registered earlier this week.

Zynga has not made any announcement about the game.  So Forestville becoming a full-fledged game is just speculation until more news emerges from Zynga.
