A non-traditional playing card deck based on The Quad Play game system. Includes 40 cards. No fixed suits. Card are arranged in two dimensions and divided in two sides, so that suits can be set dynamically. Cards have positive, negative or zero value. The deck balance is 0. The basic game ("Draw" or "Dr[4]w") rules: Each card (quad) has 4 pieces (qarts) in one colour (dark or light). These ones define the quad's cost in pts. Dark (purple) qarts have non-negative costs and vice-versa. Center purple qart gives 4 pts as all four hearts intersect each other here. Triangular qart so gives 2 pts and outer one (leaf) means 0. For example, The Good Sign (a quad with 4 purple qarts in shape of full heart) costs 8 pts in total. Players (2 by default) pick 4 quads in a turn. The summary quads' cost in each hand multiplies by 10 (multiplier from 4 to 40). Other number quads to pick is possible (with an appropriate multiplier). The number of turns is conventional (1 by default). The leader in pts wins. Actually, many traditional card games can also be played with the Quad Deck. The new game logic brings a new experience into a regular game-play. [4] The Good Sign is first of all... [4] —user summary
