Abstract
A network of individual lottery systems, for example a national network of state lotteries, each of the state lotteries operating independently using data entry and validation stations for accepting player data and having independent structure for selecting individual winners based upon coincidence of player-selected data and random data. The individual lotteries feed through to a network-level lottery having a data processor for accepting player entry data for plays in differentiated win pools at the network level. The network pools are differentiated, for example, into a red pool, white pool, and blue pool, each one being selectable by the player and each being separately accumulated and separately awarded, whereby differentiation of the pools due to probability produces competition and additional interest.
