摘要：Disclosed is a deck of rectangular playing cards usually having two substantiallyparallel long edges and two substantially parallel short edges, substantially all cards inthe deck having a front symmetrically designed with respect to both short edges, tominimize cheating by signalling with asymmetric cards. The front is usually designed to besymmetrical with respect to the short axis, and preferably the long axis as well, of eachcard. Generally, the deck includes at least 52 cards, thirteen in each of the four standardsuits, spades, hearts, diamonds, and clubs. Frequently the symmetry is obtained by theuse of at least one \"double-pip\" in the front of the card. A \"double-pip\" consists of asingle pip of a suit having asymmetric pips, the pip placed generally end to end with itsmirror image to create a single symmetric rather than asymmetric pip of the suit.Sometimes \"reversed pips\" are also used. A \"reversed pip\" is merely a pip placed upside-down on the front rather than right side up.
