Ouk Chaktrang: Khmer Chess
Cambodian Strategy Board Game
Free · Designed for iPad. Not verified for macOS.
Cambodia's own chess, made with care. Play the bot at five levels, a friend on one phone, or players online — with boards for Khmer New Year, Pchum Ben and Bon Om Touk.
Ouk Chaktrang is the traditional chess of Cambodia — a cousin of Thai Makruk and Indian Chaturanga, with its own pieces, its own opening and the counting rule that decides a long endgame. This app teaches it properly and plays it properly, in Khmer and English.
The king is the Sdach. The Neang steps one square diagonally. The Koul moves like a shield. The Trey — the fish — start on the third rank, and the whole opening follows from that.
PLAY YOUR WAY

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Version 1.1: a calmer, richer Ouk Chaktrang.
• A new look: a calm, grown-up design with 25 themes and 60 boards, including Silk Road, Timber, Jade Garden and Saffron Monastery.
• Pieces are easier to see, with soft shadows and gentle motion effects (you can turn effects off in Settings).
• Quiet background music, off by default (turn it on in Settings).
• Stats and Journey medals to track your progress.
• Better online play: a clearer duel invitation, a friend card with records, simpler room-code entry and a more reliable connection to the lobby.
• Fair duels: if nobody moves for 60 seconds, the game is cancelled with no result.
• Bug fixes and polish.
