The new pieces are:
The Octopus: - A powerful crooked slider that controls multiple files, ranks and diagonals.
The Sorcerer Snake: A piece that follows one of two crooked paths to squares that are a Knight's move away or an extended Knight's move away.
The Ninja Pawn:- A stronger pawn can also move sideways anywhere and capture sideways on the enemy half of the board.
The Ninja Pawn is not present in the intial setup but is dropped during play into a vacant space on the second rank. It can be optionally pushed forward on the same turn.
The Knights are replaced by the Ferz-Knight and the Wazir-Knight which make additional diagonal or orthogonal stepping movements.
Otherwise, the rules are exactly as in orthodox chess except for: Flexible castling (King can castle by moving 1, 2 or 3 (or 4 on Q-side) spaces towards rook, modified movement of the standard pawns and associated extended en-passant rules.
The board is set up as follows for the white side (black side will mirror this):
Rook on a1
Wazir Knight on b1
Bishop on c1
Sorcerer Snake on d1
Queen on e1
King on f1
Octopus on g1
Bishop on h1
Ferz Knight on i1
Rook on j1
10 pawns from a2 to j2.
Note that the lower right square is white, and that kings occupy the same color square.
5 Ninja pawns to be dropped one per turn into empty space from a2-j2
The Octopus takes one of two unobstructed paths:
The Octopus can go to the green squares by taking 1 diagonal step followed by two or more orthogonally outward steps.
Or it can go to the blue steps by taking 1 orthogonal step followed by 2 or more diagonally outward steps .
The Octopus captures by replacement only. It cannot jump and must travel via vacant squares along the specified paths.
The Sorcerer Snake can go to the green squares by taking either 1 diagonal step followed by 1 orthogonally outward step
OR one orthogonal step followed by 1 diagonally outward step.
Since b3 is occupied by a black pawn, it cannot move there.
The Sorcerer Snake can travel to blue squares by taking one orthognal step followed by 2 diagonally outward steps
OR it can go to the same square by taking 2 diagonal steps followed by one orthogonally outwards.
Both paths must be blocked for it not to be able to make it to the destination square.
The pawn at b3 blocks one path to a2 and the pawn at b2 blocks the other, so it cannot get to a2.
The ninja pawn can always move 1 square up or 1 square sideways to an empty square regardless of where it is situated on the board.
From the middle exactly, (rank 5 for white, rank 6 for black), the ninja pawn can move only 1 square forward, but thereafter as soon as it enters enemy territory (the upper half of the board: White rank 6-10, and for black rank 5 - 1), the pawn can go forward either 1 OR 2 empty spaces.
Like the standard pawn it can capture one square diagonally up, regardless of which half of the board it is on.
When the ninja pawn is on the top half of board (White rank 6 +, Black rank 5-) , it can also capture one square horizontally.
There is no en passant. It cannot capture another pawn or ninja pawn en passant nor can any other pawn capture it this way.
The ninja pawn promotes on the last row (rank 10 for white, rank 1 for black), to any piece. Promotion to a piece is mandatory so it would cease to be a pawn
in the last row.
Note that like the standard pawn, it can reach the promotion square from its start position in a minimum of 4 moves!
