Flatland Chess, unusual 3D chess variant

Today, searching the recesses of the depths of my computer I found the images and files of a variant of chess that I created half a year ago and that I forgot to publish.

To avoid ending up forgetting this again and filling with dust, I've thought about doing a quick post about such here.

As its name suggests, flatland chess is inspired, based and thematized on the work "flatland".

In fact, the name of classic pieces (tower, queen, horse, pawn and king) has been replaced by geometric names (hexagon, pentagon, square, line and circle), as well as the names of the new added fairy chess pieces.

Basis of the game:

The game is played in a three-dimensional board of 5x5x5 size.

There is two types of pieces in this variant: bidimensional pieces and three-dimensional pieces.

Bidimensional pieces are fast pieces, of big range (excepting lines [pawns] and circle [king]), however are confined at only one flat or layer of the cubic board (blue layer). All these have polygonal names (hexagon, square, pentagon, triangle, circle and line).

Three-dimensional pieces are slower pieces, with a low range (in fact, these only can move one step), but can move three-dimensionally, which do these very poweful as well as are trascendental in comparison to the opponent king (circle). All these have polyhedrical names (cube, dodecahedron and octahedron).

Initial positions of pieces and board image:

Board, due to be three-dimensional, has been represented using layers. So, if it has a size of 5x5x5, it was represented using five boards with a size of 5x5. 

Imagine that such boards (layers are vertically stacked.

Bidimensional pieces movement.

As I said before, bidimensional pieces only can move inside the blue layer of the board. These are their movements.

Square is basically a rook, while hexagon is a queen, pentagon a knight, and circle a king

Line is a kind of pawn, it can move and capture forward, or only capture backwards.

Triangle will move like bishop, but only can capture like rook.

Three-dimensional pieces movement.

Three-dimensional pieces can move three-dimensionally (ie, horizontally and vertically) unlike bidimensional pieces that only can move horizontally.

These are their movements:

Cube: it will move one step trigonally or diagonally.
Octahedron: it will move one step trigonally or ortogonally.
Dodecahedron: it will move one step diagonally or ortogonally. 

Thanks for read.
