Check out Symmetric Chess, our featured variant for March, 2024.

This page is written by the game's inventor, Lev Grigoriev.

Orthodia

Chess-based game on standard board, with standard rules, winning conditions, kings, etc. No diff. Except for pieces. And their moves.

Setup

As Chess setup but 4 Warriors replace the edge Pawns, Golds – the Knights, Blooming Roses – the Bishops, Ringing Bells – the Rooks, and Torch is instead of Queen.

Pieces

Pawn (p)

Type: Divergent.
As in chess. For your calm)))

Price: 1 

Warrior (w)

Type: Divergent 
Antipode of pawn.

Moves one step forward diagonally, captures one step forward.

But on start he can move two spaces diagonally forward.

Origins: Berolina.

Price: 2

Gold (G)

Type: Usual


Moves one step in any direction EXCEPT diagonally backward.

Only common piece who as captures as moves.

Origins: Shogi

Price: 4

Bisroos (Blooming Roses, B)

Type: Divergent

They are moving diagonally as Bishops, and capturing as Rooks, but 

one moment: they are making checks in those directions on which they MOVE. Kings can move in squares under their capture, because you can't capture kings.

Price: 4,5

Roobis (Ringing Bells, R)

Type: Divergent 

They are moving as Rooks, and capturing as Bishops, but they also are checking in those directions on which they move. Kings also can move to squares under their capture, and you cannot capture kings.

Price: 4,5

Torch (T)

Type: Usual


It moves on queen's straight directions but only odd number of spaces (1, 3, 5, 7 etc.). Its moves' structure is rider, i. e. if Torch meets something in 2, 4, 6, 8, etc. spaces on any straight direction, it's not stopping you, but if its move's destination is occupied, Torch is blocked to go farther.

It's only piece (except for king) who is forbidden to be the promoted form of pawn-like pieces.

Origins: CwDA for Seeping Switchers and HERE!

Price: 8

Rules

Object of the game: to checkmate opponent's king.
Draw — like FIDE chess. Pawns & Warriors can promote to Bisroos, Goldens & Roobis. (No Torches!)

En passant: Pawn can make bypassing capture as in chess (can take Pawns and Warriors); Warrior can take opponent's Warriors if they move 2 spaces, and he captures them as if they stepped 1 space.

There is no castling here.


There is standard version; also it has simplified version.

In simplified Orthodia, Blooming Roses are moving as Rooks, and capturing as Bishops; Ringing Bells are moving as Bishops but capturing as Rooks; both make check by captures' directions. There is no en-passant.

This game (simplified variation) is playable on Game Courier.
