Trò chơi Ô Ăn Quan: Vietnamese game

Ô ăn quan (literally: Mandarin Square Capturing)

a traditional Vietnamese children's board game. This game is valuable for enhancing calculating and strategic ability.

Board, pieces, and players

• A rectangle which is divided into ten squares (5x2) with two semicircles at each end is drawn on the floor or the yard. The ten squares are called "rice field square", "fish pond square" or "citizen square" and the two semicircles are called "Mandarin squares".
• Pieces may be stones, fruit seeds or any other small things.
• Two players or two teams sit in two sides of the board. Each controls one side of the players

  Setup

  Each player places one big stone or ten small stones (called the "Mandarin piece") in the Mandarin square as well as five small stones (called "citizen pieces") in each of the rice field squares.

  Objective

  The game ends when all the pieces are captured.

  If both Mandarin pieces are captured, the remaining citizen pieces belong to the player controlling the side that these pieces are on. There is a Vietnamese saying to express this situation: "hết quan, tàn dân, thu quân, bán ruộng" (literally: "Mandarin is gone, citizen dismisses, take back the army, selling the rice field") or "hết quan, tàn dân, thu quân, kéo về" (literally: "Mandarin is gone, citizen dismisses, take back the army, retreat")

  Whichever player has more pieces is the winner (a Mandarin piece is equal to ten or five citizen pieces).

  Scattering

  Players play rock paper scissors to determine the first player.

  The first player takes up all the pieces of any rice field square on their side of the board and distributes (Vietnamese: rải: literally: scatter) one piece per square, starting at the next square in either direction. When all pieces are distributed, the player repeats by taking up the pieces of the following square and distributing them.

  If their side of the board is empty, they must use five previously-won pieces to place one piece in each square on their side before repeating the distribution. (If they do not possess any pieces, they must borrow a piece from the other player and return it when counting the points at the end of the game.)

  Capturing

  When the next square to be distributed is empty, the player wins all the pieces in the square after that. A square that contains a lot of pieces is the nhà giàu square (literally: rich square).

  When the next square is an empty Mandarin square, or the next two squares are empty, it becomes the other player's turn.

  In some game variations, the Mandarin square can contain little citizen pieces called quan non (literally - quan: Mandarin; non: young) which may not be captured.
