Does anyone remember the rules for Knucks? I recall that it involved trying to run out of cards before the other person did. If you were left with cards, you got rapped on the knuckles with the flat of the deck once for each card left. There were substitutes, where hitting with different parts of the deck (e.g., the edge) counted for more than one hit with the flat of the deck.
