   I guess the rules only apply to those who follow them :)

Answers.Body: <p>You can only castle once ever.  Part of the rule for castling is that you can only castle if your king has not moved.  So obviously you can never castle again, because castling entails moving your king.</p>

Answers.Text: Of course I am sure -- I've been playing chess for over 45 years.  Again, my answer states that *part* "of the rule for castling is that you can only castle if your king has not moved".  So regardless of king and rook regaining their original squares, the king has already moved.

Comments.Text: That question's answer pretty clearly states "You have not yet moved your King." as a requirement to castle, ergo, you can only castle once.  This is the same rule cited by the only answer to this question.  (I was in the middle of answering this question on Arqade when it was migrated, but here on Chess.SE this question has been answered a few times.

Title: How often can I castle?
ThreadText: # How often can I castle?
  
  (Asked by: username_0 on 2016-01-03)
  
  I am learning to play chess on my computer. I have learned approximately all the rules but one rule stays vague for me thus far.
  
  My questions are clear, though. I am putting them separated below with some little additions.
  
  1. This is simple. **How often can I castle?** One time, two times, x
     times or till the end? I know that it can be executed if a rook and
     king are at their original places.
  2. If I am allowed to castle one time, does that imply that I can make it two times because number of rooks for each player is 2?

  You can only castle once ever. Part of the rule for castling is that you can only castle if your king has not moved. So obviously you can never castle again, because castling entails moving your king.
