You have to somehow not move your king and one of your rooks for the ENTIRE GAME except for the last move is you make your king castle and the rook delivers CHECKMATE!!!!!
here's an example

You checkmate a people by castling then you got that. But it was really hard to do that.

You need to checkmate by castling.
