I grew up in St. Albans Queens in the 50-60’s I can’t remember how one got the points. It had something to do with what you had left in the hand. But I remenber drawing for hard or soft knucks eg red or black. There was the slap with the flat of the pack. There was the smack with the edge of the pack (the scrape???) then there was putting your hand down on the ground and the deck on the fingersnails and then the winner stepped on the deck. Then there was the flying knucks…. A nice sadistic game that turned boys into men
