Internet scratch-off game

摘要

A classical scratch-off game card image is presented on web pages of participating sites in the form of a superimposed dual image responsive to a browser's cursor movement such that when a browser is appropriately authorized, movement of the cursor over the dual image causes the dominant image to dissolve and reveal the secondary image which contains the numbers or symbols used by the scratch-off game to indicate that the particular displayed scratch-off card includes a winning combination of symbols. When a scratch-off card contains a winning combination of symbols, the act of the browser scratching off the covering image to reveal the secondary image automatically advances the browser through routines which enable the browser to receive the prize or credits awarded based on the secondary image of the game card.
