Your move

💡 Need a hint?

Tap your king, then the square two steps to the side. You cannot castle out of check, through an attacked square, or into check.

What you learn here

Castling is the only move where two pieces move at once. Rules: the king and that rook have not moved, the squares between are empty, and the king is not in check and does not pass through or land on an attacked square.
