An electronic promotional game which preferably operates in conjunction with a point of sale terminal having a processor includes an electronic display screen for displaying the image of a game card. The game card has one or more selection areas which appear initially to be covered by an opaque covering which conceals game information on the card, specifically the indicia which indicates a winning game card or the premium to be awarded. An input device allows the game participant to control substitution of the game information for the opaque covering in the image, thus simulating erasure of the opaque covering in the manner of a scratch-off paper based game. The input device can include a touch sensitive screen for indicating the position to be "erased" on the image. The processor controlling the display is preferably coupled to a keyboard or product code scanner which enters the product values or the product identities, and the processor preferably selects prizes, and/or varies the odds of winning a prize, as a function of the identity of products purchased by the participant or their dollar value.
