Abstract
A random number generator and a gaming machine employing such random number generator are set forth in accordance with preferred embodiments of the present invention. The random number generator disclosed employs a white noise source to clock a counting arrangement whose maximum count exceeds the largest random number desired. A variable counter, clocked at a fixed rate, is loaded with random numbers obtained from the counting arrangement and each time the variable counter is counted down to a threshold state a new random number is read from the counting arrangement. Random numbers obtained in this mamner are then checked to ascertain their propriety and those which are accepted are then subjected to pseudo-random number regenerative techniques to further randomize the same. The resulting random numbers are then employed within a digitally controlled and operated gaming machine to select winning condition, the probabilities to be displayed during periods when wagers are accepted and otherwise to vary initial conditions associated with the gaming event prior to the actual occurrence thereof. The gaming event is then visually displayed in accordance with the winning conditions selected and any successful wagers are paid.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
