摘要:
Disclosed is an instant game card, preferably of the BINGO type, having a substrate onto which is printed a series of playing numbers. An unscratchable translucent varnish is applied onto the substrate and covers the playing numbers. A scratchable rub-off coating is applied onto the varnish, in such a manner as to surround the playing numbers without hiding the same. In use, when playing numbers are called, scratching of the scratchable rub-off coating surrounding each playing number that correspond to one of the called numbers, allow a player to visualize the position of the called playing numbers on his or her card.
