Where is the private server?
 

private server for this game ???
im originally notoriously level 12... just bored of getting nothing outta it.

Come again? Hmm, I don't really understand your question.

How long you been playing.. and where did you get the idea that we get private servers?

i been playing for bout 3 months just cannoneering n stuff cause i cant level anything over 2..

It sounds like you are basic, not unlimited for one thing, but still should be able to level up higher than 2 for weapons but not very high (not sure on limit). Basic is limited that's the simple fact, you have to pay to be able to do more.
There are no "private" servers but there are servers that are quieter (less people) - look in map to change oceans to find a quieter one.

I would guess from following along here, that the OP is likely referring to "solo" play. As in not playing online (and therefore perhaps not limited to basic account limitations).

Unfortunately that option is not available. This is an online only game. You must upgrade your account to proceed once you start hitting the "basic" account limitations.
