This is another variant that I made, and it can't be played on the Chess.com Variants page (that is why I didn't post it on Custom Variants). It is a perfectly fair game, according to Fairy-Stockfish. So if you lost in this game, don't blame me or this game, blame yourself. =)))
Ok. Let's begin!
1. Set up
Pieces are divided into two different coloured sets. While the sets may not be literally white and black, they are always referred to as "white" and "black". The players of the sets are referred to as White and Black, respectively. Each set consists of 22 pieces: one princess, two princes, two elephants, two horsemen, two castles, two archers, two cannons, and nine soldiers.
Pic 1: Initial position, the rook is the castle, and the archbishop is the archer.
2. How to play
The object of the game is to checkmate the opponent's Princess.
White moves first, after which players alternate turns, moving one piece per turn, except for castling when two pieces are moved. A piece is moved to either an unoccupied square or one occupied by an opponent's piece, which is captured and removed from play.
2.1. Pieces' movement
The Princess (note as P, for "Princess") moves and attacks 1 space diagonally. It can be put in check, checkmate, and can castle like a Chess King.
The Prince (note as W, for Chinese word: 王子 (Wángzǐ)) acts like a non-royal King (also known as a Mann). The Prince cannot castle.
The Elephant (note as E, for "Elephant") moves and attacks 1 to 2 points diagonally. It can hop over pieces.
The Horseman (note as H, for "Horseman") acts like Chess.com General (Mann + Knight).
The Castle (note as R, for "Rook", R is used to avoid confusion with Cannon) acts like a normal Rook.
The Archer (note as A, for "Archer") moves like a Knight but captures like a Bishop.
The Cannon (note as C, for "Cannon") acts like a Xiangqi Cannon.
The Soldier (note as S, for "Soldier") moves and attacks 1 space forward or 1 space sideways.
2.2. Castling
Once per game, each Princess can make a move known as castling. Castling consists of moving the Princess two squares toward a Rook of the same colour on the same rank and then placing the Rook on the square that the Princess crossed.
Castling is permissible if the following conditions are met:
Neither the Princess nor the Rook has previously moved during the game.
There are no pieces between the Princess and the Rook.
The Princess is not in check and does not pass through or land on any square attacked by an enemy piece.
Castling is still permitted if the rook is under attack, or if the rook crosses an attacked square.
2.3. Promotion
There's no promotion in this game.
