摘要 |
A scratch-off game card includes first and second sections. The first section is provided with a first set of game data covered by a substantially opaque scratch-off material. The second section is provided with a second set of game data covered by a substantially transparent material. The second section is further provided with a substantially transparent coating for marking the second section by rubbing with an object. The markings so made are erasable by, for example, pencil eraser or the like material.
