Judkin's Shogi is a modern small shogi variant, played on a board of six by six squares.
The game is probably named after its inventor. The game is very similar to Shogi
but is played with less pieces on a smaller board, and has a two row promotion
Judkin's Shogi is played on a board of 6 x 6 squares and each player has
7 pieces (including a single pawn).
The pieces are flat and wedge-shaped and are not distinguished by
colour. Although the pieces are of uniform colour the first player is
still conventionally referred to as 'Black' and the second player as
'White'. Ownership of the pieces is indicated by the direction in which
they face, with a player's pieces always pointing towards the opponent.
The players make alternate moves, with the object being to capture the
As in orthodox chess, when a 'King' is about to be captured next move and
no legal move can be made to prevent the capture, the piece is said to be
On each turn a player can either:
- move one piece according to its power of movement to a vacant square
on the board, or to a square occupied by an enemy piece (in which
case the enemy piece is captured and removed),
- 'Drop' (re-enter) a previously captured piece on almost any vacant
The opening setup is as follows: a king, a golden general (or: gold), a
silver general (or: silver), a knight, a bishop, and a rook. On the
square before the king, there is a pawn.
Both player have on their first row, from left to right: a

Each player has a Promotion Zone consisting of the two ranks (rows of
squares) furthest away from him. All pieces except the 'King' and 'Gold'
have a promoted rank and can promote on entering, moving within, or leaving
the Promotion Zone.
- The 'Rook' gains the power to move 1 square in any diagonal direction.
The 'Promoted Rook' is sometimes known as the 'Dragon'.
- The 'Bishop' gains the power to move 1 square in any orthogonal direction
and its promoted form is often referred to as the 'Horse'.
- The promoted 'Knight' moves as a 'Gold'.
- The 'Pawn' and 'Silver' move as a 'Gold' on promotion.
Promotion is not compulsory unless the piece would be unable to make a
further legal move in its unpromoted state. The 'Pawn' must therefore
promote on entering the promotion zone (the last rank). There can be
advantages in not promoting the 'Silver' immediately on entering the
As in all the games in the Shogi family, in Judkin's Shogi sets the promoted
rank is shown on the reverse side of the piece, and the piece is turned
over on promotion to reveal the new rank. The promoted 'Silver' and 'Pawn'
use different cursive forms of the Japanese character for 'Gold', so that
they can be distinguished from each other.
A captured piece is removed from the board and is held by the capturing
player. The held piece (which is said to be 'in hand') may subsequently be
'dropped' back into play on the side of the player who made the capture.
All promoted pieces revert to their unpromoted ranks when captured.
In place of a move a player may elect to 'drop' a piece held in hand back
into play. In general, a piece held in hand may be re-entered on any vacant
square, subject to the following restrictions:
- A piece may not be dropped on a square from which it has no further
legal move. (ie: a Pawn can not be dropped on the last rank).
- A Pawn can not be dropped in any file (column of squares) already
containing an unpromoted Pawn of the same side.
- A Pawn can not be re-entered directly in front of the opposing 'King'
so as to give instant 'Checkmate'.
A piece dropped inside the player's Promotion Zone is not promoted until
after it has made a further move on the board.
