This is a card game. Cards are covered with 8 yin-yangs which can be red or black. The winner is the last player with cards in his hand. Each player in turn tries to lay a card on the cards already laid out. The correspondence of yin-yangs between the card played and the card it covers defines if the move is possible and how many points are obtained. Basically, each symbol of a colour must be laid out on a symbol of the other colour. A player gets 8 points if his card completely covers the previous one or 4 points if it only covers half. For each point marked, the player can take a new card from the remaining stack. A player without any card left is excluded.
