A progressive jackpot system for a gaming network is described wherein the
accumulation of the jackpot is based upon any of a number of factors, and
the winning of the jackpot is based on any of a number of factors. In one
embodiment, the winning of the jackpot may be by any player using a
player ID card or a cash-less card to play a gaming machine. The
determination of a winner of the jackpot may be based on a random
selection of a player's ID code (or cash-less card code) by a network
computer.
