Realtime Media of Pennsylvania is filing patents round the world for an
Internet scratch-card game (W0 98/36809). The patent says players will visit a
website which displays the image of a card. The image has a patch concealing
numbers which have been generated by software designed to spew out random
numbers. The numbers are revealed by moving a cursor over the patch and clicking
the mouse to dissolve the top layer. The displayed image is then frozen and
stored. To play, the user pays by credit card. If winning numbers come up,
credit is loaded into an electronic wallet.
