Setup
Hasami Shogi uses a 9×9 board and 9 pieces per player in two distinct colors.
Hasami Shogi requires a 9×9 grid board and two sets of 9 counters in different colors (black and white). The PnP version assembles the board from two printed halves aligned along their long sides.
Setup
Each player places all 9 pieces on their own back row before play begins.
Each player places all 9 of their pieces on the row of the board closest to them (their 'back row'). Black occupies one back row and White occupies the opposite back row. The board center starts empty.
Turn structure
Players alternate turns; Black moves first. A move must always be made.
Players take alternating turns. Black always moves first. On every turn, the active player MUST make exactly one move. There are no exceptions — passing is not allowed.
Movement
A piece moves any number of empty squares orthogonally (forward, backward, left, or right) in a straight line.
On their turn, a player selects one of their pieces and moves it any number of empty squares in a single orthogonal direction: forward, backward, left, or right. The piece cannot jump over other pieces (friendly or opposing), and it cannot move diagonally unless a variant rule is agreed upon. The path must be clear of all pieces up to (but not including) the destination square.
Combat
An opponent's piece is captured if it ends up directly between the moved piece and another friendly piece along the same orthogonal line.
After a player completes their move, if one or more opponent pieces lie in a straight orthogonal line between the piece just moved and another piece belonging to the same player, those opponent pieces are immediately captured and removed from the board. This can capture any number of opponent pieces simultaneously as long as they form an unbroken chain between the two friendly pieces along the same row or column. Capture is triggered only by the moving piece completing its move — it is not triggered by the opponent's movement.
Restriction
Moving your own piece between two opposing pieces does NOT cause your piece to be captured.
If a player moves one of their pieces so that it comes to rest between two of the opponent's pieces, that player's piece is safe and is NOT captured. Sandwiching capture only applies to the player whose turn it is, and only to opponent pieces sandwiched after the move. A piece is never captured as a result of its own movement.
Combat
An opponent's piece occupying a corner can be captured by surrounding its two open sides with your pieces.
The four corner squares of the board are special. A piece in a corner has only two open (non-wall) sides. If an opponent's piece occupies a corner and a player places their pieces on both of the two open orthogonal squares adjacent to that corner, the corner piece is captured and removed from the board. This follows the same post-move evaluation as the standard sandwich capture.
Endgame
Win by capturing either 5 or 8 opponent pieces (agreed before the game).
Before the game begins, both players must agree on the capture target: either 5 or 8 opponent pieces. The first player to capture that many opponent pieces immediately wins the game.
