Dimension Chess


Dimension Chess
How to Play:
Each Board represents 3 Dimensions: Heaven, Earth, and Hell
Earth:
If a white piece captured an opponent’s piece: the opponent’s piece goes to Heaven while the capturing piece goes to Hell.
If a black piece captured an opponent’s piece: the opponent’s piece goes to Hell while the capturing piece goes to Heaven.
If a piece captured a possessed opponent’s piece: the opponent’s piece is removed from play while the capturing piece stays in Earth.
If there is already a piece in a location being teleported, that piece is removed from play and the teleported piece replaced it.
Heaven:
If a black piece is captured, it is removed from play and the white piece is teleported in Earth.
If a white piece is captured, it is teleported in Earth while the black piece remains in Heaven.
If a black piece is aligned to a piece of opposite color in Earth, the piece on Earth is possessed and cannot move.
If there is already a piece in a location being teleported, the teleported piece is removed from the game.
Hell:
If a white piece is captured, it is removed from play and the black piece is teleported in Earth.
If a black piece is captured, it is teleported in Earth while the white piece remains in Hell.
If a white piece is aligned to a piece of opposite color in Earth, the piece on Earth is possessed and cannot move.
If there is already a piece in a location being teleported, the teleported piece is removed from the game.
Healing:
If a piece of the same color is possessed by an opponent’s piece, you can capture it. The capturing piece remains in Earth while the captured piece is teleported to either Heaven or Hell depending on its color. If it is Black, the captured piece goes to Heaven. If it is White, the captured piece goes to Hell. The pawns are the only ones who can do this move.
Conjuring:
You can capture your own piece. The capturing piece remains in Earth while the captured piece is teleported to either Heaven or Hell depending on its color. If it is Black, the captured piece goes to Hell. If it is White, the captured piece goes to Heaven. The pawns are the only ones who can do this move.
Blessing:
If a piece in Earth is aligned to another piece of the same color from either Heaven or Hell, that piece cannot be captured.
Ego:
If a piece in Earth is both Blessed and Possessed, it is treated as a normal piece.
Trinity:
If a piece of the same color is aligned in Heaven, Earth and Hell. The piece on Earth is promoted to Queen.
Kings:
If a king captures an opponent's piece, the captured piece is removed from the game but the king remains in Earth.
Turn:
In your turn, you will move pieces in order of hierarchy: one in Heaven, one in Earth and one in Hell.
Goal:
The first person who delivers a checkmate wins.

No... It is not yet coded because I don't know how to... I am not confident if this is good enough for steam platform but I will give anyone the rights for it...

Prototyping is easy enough these days. A few months on an editor ( unity, godot or even unreal ) with some basic coding ( a few crash courses and some advice ) and you can see how it plays out in a basic form.
Its an interesting idea in theory. You are playing on 3 different chess boards at the same time tho. Have you thought about what the implications of this as its still a two player game? The heavan and hell both more or less will play on their own boards and pieces have to be taken twice to be removed. The blessed and possesion rules might need refining. Have you playtested it with anyone?

Not yet... I am not confident to play with anyone yet... Maybe I will try to play with myself first...

Yeah, thats the first step. It should be easy enough as all you need are 3 boards.
If you want to have a look at games that use multiple boards or dimension check out : ChessFinity on steam or other 3d chess games.

Changes:
Earth:
If a white piece captures an opponent piece, the capturing piece remains while the captured piece lands to either Heaven or Hell. If the captured piece is stronger than the capturing piece, it lands to Hell. Otherwise, it lands to Heaven.
If a black piece captures an opponent piece, the capturing piece remains while the captured piece lands to either Heaven or Hell. If the captured piece is stronger than the capturing piece, it lands to Heaven. Otherwise, it lands to Hell.
If there is a piece existing in the place the captured piece will be landing, the captured piece replaces that piece and the piece replaced is removed from play.
Note: I still need to conduct playtest with myself...
