Rek is an ancient Khmer board game designed for two players, played on an 8x8 square board. The objective is to capture the opponent's King, rather than simply checkmating it. Players utilize a total of 32 units, with each side starting with 16 units: one King and 15 Men, all of which move similarly to a Rook. The game incorporates unique capturing mechanics, allowing units to be “Rek” when they are surrounded or taken by an enemy unit.

An additional style of play, known as "Min Rek Chanh," introduces specific rules where players must capture enemy units in pairs and prohibits the Kings from moving. This variation emphasizes strategic planning and careful calculation of moves, as players must honor their opponent’s orders or face immediate loss. The game blends traditional gameplay with strategic depth, making it an engaging experience for those interested in board games.
