The rook in chess (may be referred to as the castle) is a piece that can move horizontally and vertically any amount of spaces on a chess board but can not jump over pieces. The rook usually has no purpose in the beginning of the game since it blocked by so many pieces and usually makes it into the endgame.
All chess pieces have a mathematical value. The value of a Pawn is one. The Knight and Bishop are generally valued as three; the Rook as five and the powerful Queen a ten. The difference between the Knight and Bishop at three versus the Rook as a five is the ability of a Rook-King combination to checkmate your opponent.
