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.

Why it's free to use
- Filed March 15, 1994 and granted May 13, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 15, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 15, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
