1. Mandarin Square Capturing (O an quan)
Mandarin Square Capturing is one of Vietnam’s oldest and most intellectually stimulating folk games. It is typically drawn in the dirt or on paper, with a rectangular grid comprising five small squares on each side and two semicircular "Mandarin" squares at both ends. Traditionally played by children in rural areas, especially in schoolyards or village corners, this game fosters arithmetic thinking and strategic planning.
Two players take turns moving small objects (stones, seeds, or shells) in a counterclockwise direction from one square to another, attempting to "capture" their opponent’s pieces by strategic placements. The game ends when all the smaller squares are empty, and the winner is the one with the most captured pieces. It teaches math, logic, counting, and patience.
