A computer activated system and method for selling pre-printed instant-winner lottery tickets, or digital simulation games, by use of a central computer communicating with widely-distributed terminals (including mobile devices and PCs), with each ticket providing a traditional instant-winner game with a chance for an added instant winner progressive jackpot and/or non-pre-designated fixed jackpot prize and/or the display of the simulation of such game on a terminal in conjunction with the optional display of advertising, and/or advertisers' images, and/or promotional offerings. The identification code printed on each ticket is read by a code reader, after the ticket has been issued from a vending machine, a clerk-assisted terminal, a digitally displayed terminal, or selected from an accessible display of inactive tickets, and the computer determines whether the ticket is a winner, and notifies the terminal at which the ticket is processed of the win or loss.
