The link above shows instructional diagrams.
In order to castle, 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
Drag the king two places toward the rook and the computer will swap their positions.

PLEASE HELP!!!! THANK YOU":-d
