Abstract: A method of, and system for, wagering. The method includes the step of providing a random number generator that has a wagering base that is derived at least in part from the outcome of at least one horse/dog race or jai alai game that has previously been completed. Certain information in the wagering base is based at least in part on the outcome of the at least one horse/dog race or jai alai game and is accessible through an input wager, with the probability of accessing the certain information in the wagering base through an input wager being different. Input wagers are directed to the random number generator during the wagering period from each of multiple locations. Between when preliminary and final return amounts are identified for a first input wager that accesses the certain information, based at least in part upon the number of input wagers that have accessed the certain information, an updated return amount is identified for the first input wager.
