  • Patent number: 4995615
    Abstract: A method for achieving fair card games including the steps of: randomly generating distinct numbers corresponding to each one of the cards employed for the card games; printing out the sequence of the predetermined distinct number on a sheet which is covered so as not to be visible by players before and during processing of the play; displaying sequentially the cards being distributed or drawn throughout the processing of the card games; and sending out the sheet with a sequence of the randomly generated numbers printed on it and comparing to the displayed sequence after the card game is over. The apparatus for playing fair card games comprises a registering and printing device designed to cooperate with a printer for sending out the sheet. The registering and printing device includes a curved double-layer plate which is composed of a transparent upper layer and an opaque lower layer. A gap is formed between the two layers for carrying and conveying the sheet.
