Hook Shogi

Introduction

Hook Shogi (鉤将棋 kō shōgi, "hook shogi") is inspired by Maka Dai Dai Shogi and Taishin Shogi. The latter is by far the largest and craziest game I have ever conceived. Taishin Shogi can be a bit intimidating, though, with 177 pieces of 86 types on a 25x25 board. Hook Shogi is an attempt to shrink Taishin Shogi to a smaller game, with only 109 pieces of 51 types on a 19x19 board, without losing much of the original flavor of the original game.

Setup

An interactive diagram has been provided (The Javascript source code was written by H. G. Muller) to make it easier to understand how each piece moves. The Mnemonic piece directory uses H. G. Muller's Mnemonic pieces. The Shogi pieces used in the diagram are my own pieces, made using a free online pixel art drawing tool called Pixilart.

Below is a table describing the moves of each piece. The table's contents are limited to the name and move description of each piece to prevent the HTML code from messing with the format of the page.

 

The King can move into check at any time, although this is almost always a blunder.

Pieces that appear in the initial setup

Piece

Move description

King

The King can step 1 square in any direction.

Drunk Elephant

The Drunk Elephant can step 1 square in any direction except directly backward.

Dark Spirit

The Dark Spirit can step 1 square in any direction except diagonally forward to the left.

Deva

The Deva can step 1 square in any direction except diagonally forward to the right.

Hook Mover

The Hook Mover can slide orthogonally, then (optionally) make a 90-degree turn and continue in a perpendicular direction. It must stop when it captures, and the (bent) path it travels along must be empty up to that point. It can only change direction once per move.

Tengu

The Tengu can step 1 square orthogonally or slide diagonally, then (optionally) make a 90-degree turn and continue in a perpendicular direction. It must stop when it captures, and the (bent) path it travels along must be empty up to that point. It can only change direction once per move, and only when moving diagonally.

Lion

The Lion has a special movement ability commonly called a 'lion move' or 'lion power'. It can step up to three times in a straight line in any orthogonal or diagonal direction. It can make the first (or second) step as a jump, when it chooses to do so. So it can:

  • Jump directly to any square in the 5x5 area surrounding it,
  • Capture any adjacent piece without moving (igui),
  • Capture a piece on an adjacent square, and then continue to any of the squares adjacent to that square, capturing up to two pieces (this is equivalent to 2 turns for a King),
  • Stay in place without capturing anything if at least one adjacent square is empty, effectively passing a turn

Lion Dog

The Lion Dog has a special movement ability commonly called a 'three square lion move' or 'three square lion power'. It can step up to three times along any one orthogonal or diagonal, capturing up to two pieces. That is, unlike the lion itself, but like the soaring eagle and horned falcon, it is restricted to moving in a straight line and cannot move to the in-between squares when making a three square lion move. It can make the first (or second) step as a jump, when it chooses to do so. So it can:

  • Jump to the first, second, or third square in any orthogonal or diagonal direction,
  • Capture any adjacent piece without moving (igui),
  • Capture a piece on an adjacent square, and then continue to the second or third square in the same direction, capturing up to two pieces,
  • Capture a piece on the second square in any orthogonal or diagonal direction, then retreat to the first square (2 steps out, 1 in) or continue to the third square, capturing up to two pieces,
  • Stay in place without capturing anything if at least one adjacent square is empty, effectively passing a turn

If it skips a turn or captures without moving, it cannot then continue in the opposite direction: it is restricted to one orthogonal or diagonal.

Pieces that only appear with promotion

Piece

Move description

Emperor

The Emperor can jump to any square on the board. However, it cannot capture a royal piece (a King, Prince, or another Emperor) that is protected, even if this move would win the game.

Aside from the restriction above, the Emperor can move into check at any time, although this is almost always a blunder.

Divine Dragon

The Divine Dragon moves either as a Lion or as a Queen. This power includes jumping, igui and skipping a turn (see "Lion").

Teaching King

The Teaching King moves either as a Lion Dog or as a Queen. This power includes jumping, igui and skipping a turn (see "Lion Dog").

Lion Hawk

The Lion Hawk moves either as a Bishop or as a Lion. This power includes jumping, igui and skipping a turn (see "Lion").

In other words, the Lion Hawk is a Lion enhanced by the diagonal moves of the Queen.

Free Eagle

The Free Eagle moves as a Queen. In addition, it can move one square in any diagonal direction twice. This power includes jumping, igui and skipping a turn (see "Lion"). So it can:

  • Jump directly to any square in the second square in any direction,
  • Capture any diagonally adjacent piece without moving (igui),
  • Capture a piece on a diagonally adjacent square, and then continue to any of the squares diagonally adjacent to that square, capturing up to two pieces (this is equivalent to 2 turns for a Ferz),
  • Stay in place without capturing anything if at least one diagonally adjacent square is empty, effectively passing a turn

In other words, the Free Eagle is a Queen enhanced by the diagonal moves of the Lion.

Furious Fiend

The Furious Fiend can move as a Lion or as a Lion Dog. That is, it can make up to 2 King steps per turn, changing direction between them, even when this returns it to its starting square, or step up to three times in a straight line, capturing up to two pieces. It can make the first (or second) step as a jump, when it chooses to do so. So it can:

  • Jump directly to any square in the 5x5 area surrounding it or jump to the third square in any orthogonal or diagonal direction,
  • Capture any adjacent piece without moving (igui),
  • Capture a piece on an adjacent square, and then continue to any of the squares adjacent to that square or to the third square in the same direction, capturing up to two pieces (the former is equivalent to 2 turns for a King),
  • Capture a piece on the second square in any orthogonal or diagonal direction, then retreat to the first square (2 steps out, 1 in) or continue to the third square, capturing up to two pieces,
  • Stay in place without capturing anything if at least one adjacent square is empty, effectively passing a turn

If it skips a turn or captures without moving, it cannot then continue in the opposite direction: it is restricted to one orthogonal or diagonal.

Phoenix Master

The Phoenix Master can slide orthogonally or diagonally backward. In addition, It can step 3 times, or jump up to 3 squares, diagonally forward, capturing up to two pieces. This power includes igui and skipping a turn, but not moving off the diagonal. (see "Lion Dog").

Kirin Master

The Kirin Master can slide diagonally, sideways, or directly backward. In addition, It can step 3 times, or jump up to 3 squares, directly forward, capturing up to two pieces. This power includes igui and skipping a turn, but not moving off the orthogonal. (see "Lion Dog").

Soaring Eagle

The Soaring Eagle can slide orthogonally or diagonally backward. In addition, It can step twice, or jump two squares, diagonally forward, capturing up to two pieces. This power includes igui and skipping a turn, but not moving off the diagonal. (see "Lion").

Horned Falcon

The Horned Falcon can slide diagonally, sideways, or directly backward. In addition, It can step twice, or jump two squares, directly forward, capturing up to two pieces. This power includes igui and skipping a turn, but not moving off the orthogonal. (see "Lion").

Skyward Net

The Skyward Net can slide orthogonally. In addition, it can make a '2-square area move' - up to 2 King steps in independently chosen directions, stopping at the first capture. It can skip a turn, but it does not have the lion power of igui.

Earthward Net

The Earthward Net can slide diagonally. In addition, it can make a '2-square area move' - up to 2 King steps in independently chosen directions, stopping at the first capture. It can skip a turn, but it does not have the lion power of igui.

Rules

Deciding who moves first

furigoma (振り駒 piece toss) is used to decide who moves first. One of the players tosses five pawns. If the number of tokins (promoted pawns, と) facing up is higher than unpromoted Pawns (歩), then the player who tossed the pawns plays Gote (後手 White) (that is, getting the second move).

The players may also decide who goes first through a game of chance or a mutual agreement.

Sente (先手 Black) moves first, then players alternate making a move. Making a move is required – skipping a move is illegal, even when having to move is detrimental. Play continues until a player's last remaining royal piece is captured, a player resigns, or a draw is declared.

Skipping a turn

The Lion Hawk, Free Eagle, Furious Fiend, Lion, Lion Dog, Soaring Eagle, Horned Falcon, Divine dragon, Teaching King, Skyward Net, Earthward Net, Phoenix Master, and Kirin Master have the ability to skip a turn if at least one adjacent square is empty. (The Free Eagle can only do this on the squares diagonally adjacent to it, the Golden Bird can only do this on the squares orthogonally adjacent to it, the Horned Falcon and Kirin Master can only do this on the square directly in front of them, and the Soaring Eagle and Phoenix Master can only do this on either of the two squares diagonally in front of them.) However, it is illegal for a player to skip a turn more than one consecutive time. That is, a player is not allowed to perpetually skip a turn.

Promotion

Whenever a piece captures something, it promotes. Promotion is indicated by turning the piece over after it moves, revealing the character of the promoted piece. Promotion is mandatory - it is illegal to defer the promotion of a piece that has just captured, even when having to do so is detrimental. It is also illegal to promote a piece without capturing, with the following exception:

When a Pawn, Stone General, or Iron General reaches the last rank, it may promote even on a non-capture. This is because these pieces cannot move backwards or to the sides, and would otherwise have no legal move on subsequent turns. This last-rank promotion of a Pawn, Stone general, or Iron general can likewise be declined, leaving it as an immobile "dead piece" (死に駒 shi ni koma). However, if these pieces capture something on the last rank, they must promote without exception.

The pieces promote as follows:

  • King -> Emperor
  • Drunk Elephant -> Prince
  • Dark Spirit -> Divine Dragon
  • Deva -> Teaching King
  • Lion -> Lion Hawk
  • Lion Dog -> Furious Fiend
  • Queen -> Free Eagle
  • Fire Dragon -> Kirin Master
  • Water Dragon -> Phoenix Master
  • Earth Dragon -> Earthward Net
  • Wind Dragon -> Skyward Net
  • Dragon King -> Soaring Eagle
  • Dragon Horse -> Horned Falcon
  • Rook -> Dragon King
  • Bishop -> Dragon Horse
  • Vertical Chariot -> Free Dream Eater
  • Side Chariot -> Free Demon
  • Vertical Mover -> Flying Ox
  • Side Mover -> Free Boar
  • Right Chariot -> Right Army
  • Left Chariot -> Left Army
  • Reverse Chariot -> Whale
  • Lance -> White Horse
  • Poisonous Snake -> Hook Mover
  • Warrior -> Tengu
  • Phoenix -> Queen
  • Kirin -> Lion
  • Knight -> Side Soldier
  • Roaring Dog -> Lion Dog
  • Flying Dragon -> Fierce Eagle
  • Flying Horse -> Violent Falcon
  • Blind Tiger -> Flying Stag
  • Ferocious Leopard -> Bishop
  • Reclining Dragon -> Free Dragon
  • Old Monkey -> Mountain Witch
  • Blind Dog -> Wizard Stork
  • Coiled Serpent -> Free Serpent
  • Evil Wolf -> Free Wolf
  • Angry Boar -> Running Boar
  • Cat Sword -> Freee Cat
  • Gold General -> Rook
  • Silver General -> Vertical Mover
  • Copper General -> Side Mover
  • Iron General -> Vertical Soldier
  • Tile General -> Vertical Chariot
  • Stone General -> Side Chariot
  • Earth General -> Reverse Chariot
  • Dog -> Multi General
  • Pawn -> Gold

Because promotion doesn't happen until the end of the turn, multi-capturing pieces that promote have a chance for a double capture.

The Hook mover and Tengu do not promote, nor can already promoted pieces promote further, with the following exception:

Any piece that captures a Deva or Teaching King promotes to a Teaching King. Similarly, any piece that captures a Dark Spirit or Divine Dragon promotes to a Divine Dragon. Multi-capturing pieces that capture both a Deva or Teaching King and a Dark Spirit or Divine Dragon promote to the promoted form of the piece they took on the second capture. The only exceptions to this rule are royal pieces and potentially royal pieces (Emperors,Kings, Princes, and Drunk Elephants) which promote to their normal promoted forms, or stay as they are if already promoted.

Below is an image of one army with all pieces promoted (except for the unpromotable ones). This image, like the one in the Setup section, uses H. G. Mullers's Mnemonic pieces. The pieces with dots in the center are the promoted forms of pieces that occur in the initial setup.

Check

When a player’s last remaining royal piece (an Emperor, King, or Prince) is under immediate attack by at least one enemy piece, it is in check. A player who's last remaining royal is in check is not required to remove the check, but this is almost always the best option, since a player who has no more royal pieces on the board loses the game. If a player has more than one royal piece in play, that player may sacrifice one (or two) of them. A check can be removed in one of three ways, depending on the situation:

  • Blocking the check by placing a piece in between the royal piece and the attacking piece
  • Capturing the attacking piece
  • Moving to a safe square
  • Protecting the royal piece (if the attacking piece is an Emperor)

The Emperor, King, and Prince need not move out of check, and can even move into check, though this is almost always a blunder. If it is not possible for a player who only has an Emperor, King, or Prince to get out of check, that piece is checkmated and the game is effectively over.

Illegal Move

A player who makes an illegal move loses immediately. Illegal moves include:

  • Making more than one move per turn
  • Skipping a turn two consecutive times
  • Moving a piece contrary to how its movements are defined

This rule may be relaxed in casual games, where a player can take back the illegal move and make a legal move.

End of the game

A player who captures the opponent's last remaining royal piece (an Emperor, King or Prince) wins the game.

Checkmate and Stalemate

If a player’s last remaining royal piece is placed in check and there is no legal move that will resolve the check, the checking move is also checkmate, and effectively wins the game.

If a player’s last remaining royal piece is not in check but that player has no legal moves, the game is a stalemate. Stalemate, like checkmate, leads to a win for the stalemating player.

Resignation

At any point in the game, a player may resign and their opponent wins the game.

Draw

There are only two ways for a draw to occur - 千日手 sennichite (repetition) and impasse.

Repetition Draw 千日手 sennichite - If the same game position occurs four times with the same player to move, then the game ends in a draw, as long as the positions are not due to skipping a turn two consecutive times.

Impasse – If neither player can hope to force checkmate or stalemate on the other player’s last remaining royal piece or gain any further material through a series of legal moves, the players may agree to a draw.
