How is it done? (Tower - King)

Dear friends, I need to learn how to do the change King - Tower... I tried different options and I tried to find around chess.com and I didn't find anything about it. So, I would be greatful if someone could tell me how to do it.

Thanks!

I guess you are talking about castling.. You can go through the below forum..

Castling

One other special rule is called castling. This move allows you to do two important things all in one move: get your king to safety (hopefully), and get your rook out of the corner and into the game. On a player’s turn he may move his king two squares over to one side and then move the rook from that side’s corner to right next to the king on the opposite side. (See the example below.) In order to castle, however, it must meet the following conditions:

• it must be that king’s very first move
• it must be that rook’s very first move
• there cannot be any pieces between the king and rook to move
• the king may not be in check or pass through check

Notice that when you castle one direction the king is closer to the side of the board. That is called kingside. Castling to the other side, through where the queen sat, is called castlingqueenside. Regardless of which side, the king always moves only two squares when castling.

Thank you very much friend!
