Abstract: The present invention provides a probability generating apparatus offering unexpectedness and an excellent unfair act preventing function. The probability generating apparatus includes a parallel random number generator offering uniformity and consecutively generating random numbers.

Abstract: A method of uniforming physical random numbers while concurrently maintaining a random number generating rate and ensuring security. The method sequentially inputs a plurality of physical random numbers to a shift register to hold them there, and shifts them every time a reference pulse signal rises. Physical random numbers held in the shift register are randomly selected and output by a selector based on part of them. Accordingly, physical random numbers input to the shift register are uniformed and then output even thought they have a deviation, thereby eliminating the chance of not outputting random numbers or letting others recognize the deviation of random numbers.

Abstract: The present invention provides a probability generating apparatus offering unexpectedness and an excellent unfair-act preventing function. A probability generating apparatus 1 comprises a parallel random number generator 2 offering uniformity and consecutively generating random numbers. The probability generating apparatus 1 sets, as data for generation of probability, data generated on the basis of the random numbers using a trigger signal as a base point. The probability generating apparatus 1 compares the data for generation of probability with range data to output a win/loss probability signal. The data for generation of probability is data n generated on the basis of a random number corresponding to the time when the trigger signal is generated. The data n is the n-th random number from the trigger signal. With the present arrangement, the data for generation of probability is the random number generated at an indeterminate time after the trigger signal is generated.
