About this game
Janggi (장기) — Korean chess for your phone. Play the authentic 9×10
board game with full tournament rules, byo-yomi clock, and a complete
saved games library. Offline. No ads. No accounts.
▶ WHAT IS JANGGI?
Janggi (장기) is the Korean variant of chess. Two armies — Cho (楚, blue)
and Han (漢, red) — race to checkmate the opposing General on a 9×10
board. Pieces sit on intersections, not squares. The General never
leaves his 3×3 palace. Cannons hop over a single screen piece. Horses
and Elephants can be blocked. It's a game of patient maneuvering,
tactical jumps, and tight palace endgames.
If you know international chess or Chinese chess (Xiangqi), you'll feel
at home — but Janggi has its own rhythm and depth.
▶ AUTHENTIC TOURNAMENT RULES
Built to the modern KJF / janggimodern standard. No house rules.
• Four canonical opening formations (마상마상 / 상마상마 / 마상상마 / 상마마상)
• Perpetual check loses for the checking side
• Double pass ends the game as a draw
• 4-fold repetition triggers material count
• 50-move rule (100 plies) for quiet positions
• Auto-pass when you have no legal move and aren't in check
If you've learned Janggi from a Korean teacher or book, the rules will
feel right.
▶ BYO-YOMI CLOCK (秒読み / 초읽기)
Asian-style time control with five tournament presets:
• Lightning — 1 min + 10s × 3
• Blitz — 3 min + 10s × 3
• Rapid — 10 min + 30s × 3
• Classical — 30 min + 60s × 5
• Untimed — for casual study
Each byo-yomi period renews after a successful move, just like at the
real board.
▶ NEVER LOSE A GAME
Every active game is auto-saved. Close the app, switch phones, come
back days later — your position is still there. Tap "Resume game" and
play on.
Every finished game lands in your saved games library automatically.
Browse up to 50 past games, replay any of them, copy their full move
history to your clipboard, or import games shared by friends.
• Auto-save active game with one-tap resume
• Saved games library with full move history
• Export to clipboard in standard Korean notation
• Import any exported game by pasting the text
▶ TWO WAYS TO PLAY
• Pass-and-play on a single device for two human players
• Versus computer (you play Cho, the AI plays Han)
No internet connection required. No accounts. No ads. No tracking.
▶ BEAUTIFUL & ACCESSIBLE
• Light and dark themes, both verified against WCAG AA contrast
standards — easy on the eyes day or night
• Automatic theme follows your system settings
• Traditional Hanja characters (將, 士, 象, 馬, 車, 包, 卒) or simple
Latin letters — your choice
• Coordinate labels for studying notation
• Flip the board for either player's perspective
• Haptic feedback on moves, captures, check, and game end
• Three languages: English, 한국어, Polski
▶ BUILT FOR LEARNERS
• 4-step in-app tutorial covers piece movement, blocking rules, cannon
screens, palace mechanics, and how games end
• Visual move hints: legal moves shown as dots, captures as rings,
last move highlighted, check ring on the General
• Korean-style notation (R91xC91, K54-44+, H21-22#) — the same
notation used in Korean Janggi books
• Undo any move at any time to explore variations
▶ WHY JANGGI?
Janggi is one of the most popular board games in Korea, played from
city parks to national tournaments. It's faster than international
chess, more tactical than Xiangqi, and the palace-bound General
creates endgame puzzles you won't find in any other chess variant.
Whether you're new to Asian board games, a chess player exploring
something different, or a returning Janggi player who wants
tournament-quality rules in your pocket — this app is for you.
