The rook moves in straight lines.
It can move forward, backward or sideways, as far as it likes.
Now look at the board: the rook can move to all 14 squares that have a plus sign in it.
In one move, a rook can cross the whole board.
But a rook can’t jump over other pieces.
The rook looks like a castle.
That is why people used to call the rook a castle.
What do you have to do?
First, move the rook to collect all the coins.
