A game somewhat similar to 'noughts and crosses' on a much larger
This game is known as Pong hau k'i in China and Ou-moul-ko-no in Korea. Find a friend to play or try the interactive version online.
Equipment: 4 by 4 board, 4 counters of one colour (4 dragons)
and 12 of a second colour (12 swans).
MOVES: All moves are horizontal or vertical, never diagonal.
DRAGONS try to capture the swans. A dragon either moves one
square to an adjacent square or captures a swan by jumping over it
to an empty square the other side.
SWANS try to surround the dragons so that the dragons are unable
to move. Swans cannot jump or capture dragons.
START: The game starts with the four dragons at the corners of
the board and no swans on the board.
PLAY: Swans start by placing one swan on a vacant square. Play
alternates. A dragon must be moved when it is that player's turn.
The swans are placed, one at each turn, in a vacant square and no
swans can be moved until all the swans have been placed on the
board. After that players take it in turns to move until either the
dragon wins by capturing all the swans or the swans win by blocking
in the dragons so they cannot move.
