Abstract: Playing cards are provided to preventing card edge sorting in a card game. The playing cards back design is made up of irregular design elements. The irregular design elements mask the variances, making the differing pattern in the edge cuts difficult to detect with the naked eye. The irregular design elements can take the form of not commonly recognized geometric shapes used to create a repeating pattern. The irregularities in the sides and shapes of the irregular design elements is then repeated throughout the back design. Using shapes with greater than five sides can serve to make it increasingly more difficult to detect individual elements of the repeating pattern. Some use line elements in combination with the shapes to break up the pattern and draw the eye away from specific sections making it harder to isolate the shape being used.
