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. An opaque board is further provided to cover a portion of the double-layer plate so that the sheet is temporarily invisible.

Claims

1. A method for playing a card game involving the random production of cards in a single sequence, wherein all the cards in the sequence are equally likely to be produced so that an assumption of equal likelihood for computing probabilities is valid, said method comprising the steps of:

(a) printing out a single random sequence of the cards on a sheet on which the sequence is covered so as not to be visible by players before and during the play;

(b) completing the play of the cards by producing them one at a time in the foregoing sequence; and

(c) after the play is completed, uncovering the printed sequence so that it can be compared with the produced sequence.

2. The method of claim 1 in which the card game is black jack.

3. The method of claim 1 in which the sequence is re-shuffled and the printout follows the last re-shuffle.
