Rules

Seireigi

Seireigi differs from shogi in its promotions. To win you have to checkmate the king of your opponent.

Board

The board is a 9x9

Pieces

for each team:

Initial setup

We made a western set of pieces for players who might not be familiar with the traditional japanese version.

Pieces actions and properties

Gold general: moves and captures to adjacent squares in any orthogonal or the forward diagonal direction.

Silver general: moves and captures to adjacent squares in any diagonal or the forward orthogonal direction.

Pawn : The Pawn: moves and captures to the square directly in front of it.

Rook : as in chess.

Bishop : as in chess.

King : as in chess.

Knight : The Knight has the two forward-most moves of the Chess knight.

Lance : The Lance moves as a Rook but only forward in the same file, never sideways or backward.

Promotions

Great elephant is the promotion of Gold general

Running wolf is the promotion of Silver general

Heavenly horse is the promotion of Knight

Free tiger is the promotion of Lance

Pawn promotes to Tokin, which move like a Gold general.

Rook and Bishop gain king move upon promotion to Dragon king and Dragon horse, respectively.

The promotion zone is the farthest three rows of the board, and a piece may promote if part of its move touches the zone. Promotion is optional unless no subsequent move is possible otherwise. So a Pawn or Lance must promote on the last row, and a Knight must promote on the last two rows.

The King does not promote, nor can already promoted pieces promote further.

Drops

Captured pieces become prisoners and lose their promotion, guarded on your right. You can use your turn to put them back into play. A player can either move one of his pieces or drop a prisoner back into play on his behalf.

A Pawn can’t be dropped on a column with an unpromoted Pawn of the same color.

A Pawn can’t make an immediate checkmate when dropped. It is allowed for other pieces.

A piece can’t be dropped is no subsequent move is possible, so a Pawn or Lance cannot be dropped on the last row, and a Knight cannot be dropped on the last two rows.
