I grew up playing Skully in Brooklyn and Queens in the late fifties. We were never sure how the name of the game was spelled, because there was no occasion to ever actually write the name.

We used to melt candle wax into the bottle caps to give them weight, and for some reason, the beer bottle caps were always considered to be the best to have.

One of the terms of the game that I haven’t yet seen in various versions of written rules I’ve come across is “Heading for the Hills”. This was when your opponent became a killer and needed to hit you three times in a row to get you out, so you would keeping blasting your own cap down the block so he could hopefully never catch you. “Heading for the Hills” was not really “fair” and usually not allowed but sometimes it was, depending on the mood of the players that day.
