Yin Yang is an ancient Chinese philosophy, that two complementary forces exist in the universe. Many natural dualities—e.g. dark/light; female/male; low/high; cold/hot—are examples of yin yang.
One is not better than the other. Rather, both are necessary and a balance of both is optimal. In the card game Yin Yang, the player who best succeeds in balancing these two forces will be the winner.
This trick-taking card game, that plays equally well with 3, 4 or 5 people, challenges players to try and score “0” points. Each player, in turn, places a card from their hand onto the table. The high card receives positive points (black Yin chips) and the low card receives negative points (white Yang chips). When a player has collected both black Yin and white Yang chips, he returns them in pairs—one black and one white—until he has only one color, or ideally, “0” chips left. The challenge—take only the tricks you need to achieve balance “0”, otherwise avoid winning tricks.
“The game isn't difficult to learn or play, but it does present the players with some interesting hand management decisions. It works wonderfully as a filler for experienced gamers, and is a great choice to play with families and friends.”
