You got it right!

To mean, "you are correct", we sometimes say:

1) you got it right!

2) you've got it right! (used in BE, not sure about AE)

3) you've gotten it right! (used in AE??)

Are they all correct and mean the same thing? Are they past and present perfect forms of the verb "to get"?

I ask this because the verb "get" is sometimes very confusing, and on a few occasions, its past form "got" is interchangeably used with the verb "have" or "have got", especially in AE, as in, "I got this" and "I've got this", both meaning "I can/will do it".
