01 · The game
What is Janggi?
Janggi (장기), usually called Korean chess in English, is a two-player strategy board game. It belongs to the same chess family as chess, xiangqi and shogi, but plays differently: an open board, long elephants, jumping cannons and active palace diagonals.
Pieces stand on the intersections of nine vertical files and ten horizontal ranks. Cho’s blue-green army begins at the bottom and moves first; Han’s red army begins at the top and starts scored games with an extra 1.5 points. Each general remains inside a three-by-three palace marked with diagonal lines.
02 · The objective
How to win
Players alternate turns, moving one piece or choosing to pass. You win by checkmating the opposing general: attack it in a position where the other player has no legal move that removes the threat. A move that leaves your own general attacked is not legal.
Captures happen by moving onto an enemy piece. Unlike chess, stalemate does not end a Janggi game because a player may skip a turn. In this app, two passes in a row stop the game and the points from the pieces still on the board decide the result.
03 · Seven kinds of piece
How the pieces move
Every piece captures the same way it normally moves. A piece may never land on a point occupied by its own army. Tap a piece below to see its movement on a small board.
Piece style
General 궁 · 장Moves one point along any drawn line and may never leave its own palace. Checkmate this piece to win.
Guard 사Moves exactly like the general: one point along a line, always inside its own palace.
Chariot 차Moves any distance horizontally or vertically, or along a straight palace diagonal, until blocked.
Cannon 포Moves like a chariot after jumping exactly one piece. That piece cannot be another cannon, and a cannon cannot capture a cannon.
Horse 마Steps one point straight, then one diagonally outward. Any piece on the first point blocks it.
Elephant 상Steps one point straight, then two diagonally outward. Either point on its route can block it.
Soldier 졸 · 병Steps one point forward or sideways, never back. In the enemy palace it can also follow a forward diagonal.
Traditional values: chariot 13 · cannon 7 · horse 5 · elephant 3 · guard 3 · soldier 2
Movement and values are based on the Korea Janggi Association’s piece rules. The rules research for this game records the translations, comparisons and decisions behind this summary.
04 · What makes it different
Rules unique to Janggi
Cannons must jump
A cannon must jump exactly one piece even for an ordinary move. It cannot jump over another cannon, and one cannon can never capture another.
Palaces have active diagonals
Generals and guards use their own palace lines. Chariots and cannons can use the diagonals in either palace, while invading soldiers can step diagonally forward.
You choose the opening arrangement
Before play, each army chooses how its two horses and two elephants alternate on the back rank. The four standard arrangements change which side of the board develops first.
You may pass
Skipping a turn is a normal part of Janggi, except while your general is in check. This is why the game has no stalemate ending.
Facing generals create bikjang
When the two generals face down an open file, a player may call bikjang (빅장). What that call decides depends on the match format.
The rules and match sources cover palace lines, cannons, passing and bikjang. The opening research explains how the four starting arrangements were compared and named.

Casual and scored Janggi
Casual
The familiar online game
The armies begin in the common arrangement and can be rearranged before the first move. A called bikjang ends the game as a draw, and so does an agreed draw or, once both sides are under 30 points, the same position standing a third time. This is the simplest format for learning and local play.
Scored
The tournament reading
Han chooses an arrangement first, Cho responds and Han begins with an extra 1.5 points. Bikjang can normally be called only when both sides have fewer than 30 points left, and the result is decided on points. So is a game that goes round in circles under 30 points.
This game supports both readings because published rules describe both formats. See the rule sources and research notes for the primary Korean sources and translations.
