Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0040] like figure 1 As shown, playing cards 100 are made from a single-use molded plastic sheet.

[0041]The opposite upper and lower sides 180 , 190 of the playing card 100 respectively have a holding groove 110 , and the holding groove 110 is a smooth curve.

[0042] The playing card 100 is symmetrical about a center point 150 . Wherein, the center point 150 is the intersection point of the diagonal line 130 of the playing card and the center line 160 of two opposite sides.

[0043] The playing card 100 is asymmetrical about the centerline 160 of the two sides 180 , 190 .

[0044] The depth of the pressing groove 110 is 1 / 20 of the length of the playing card 100 .

[0045] The central part of the pressing groove 110 has the deepest depth and the smallest curvature radius; along the central part of the pressing groove 110 to its two side...

Abstract

The invention provides a playing card (100), a pressure holding groove (110) is arranged at least one side of the playing card (100). Compared with the prior art, the playing card (100) has the advantages that: firstly, a shuffle person can simply and conveniently shuffle the card; secondly, a player can hold more playing cards with smaller hand palm and less holding force; thirdly, when a certain playing cards are placed reversely, the corresponding reversed playing cards can be simply and conveniently found; in addition, the playing card (100) has the advantages of high strength and being not easy to be damaged.

The elasticity and the pressure given by the thumb turn it over for shuffling. [0004] Because the playing cards are rectangular and each side is a straight line, when shuffling the cards, the thumb on one side of the playing cards is easy to slide along this side, so that the pile of cards will scatter, so that the purpose of shuffling cannot be achieved. In order to better hold the stack of playing cards, it is common practice for the shuffler to increase the pressure of the thumb o...
