Abstract
A system is described for facilitating an Internet-based game of chance, particularly a computer-based version of a punchboard game having a grid with prizes associated with the various grid locations. The user can pay a central controller for each selection by providing a credit card number, or through other Internet transaction means. The central controller sends the user a fresh virtual punchboard (i.e. a game in which no selections have yet been made). The user selects a grid location, encrypts it, and then transmits it to the central controller. The central controller then generates prize values for the grid that it sent to the player. The user's computer stores the locations of each prize and determines whether the player's selection was a winner. If he has won, the player sends the decryption key to the central controller to decrypt his grid selection and authenticate his selection. The central controller then initiates a payment to the user.
