In North Carolina we played a game in the 60's called pill 8. Everyone draws 3 pills. You keep two secret and throw the other one on the table. Low pill on the table breaks, next lowest shoots second, etc.
The shooter at the table can always shoot either the highest or the lowest ball on the table. For instance, if nothing goes on the break the first shooter can pocket the 1 or the 15 and keep shooting. If he pockets the 1 then the 2 and the 15 are the object balls. Always the highest or the lowest.
You win the game when the balls corresponding to your two pills have been pocketed either by you or any other shooter and when it is your turn you display your pills to show that they have been pocketed and call and make the 8-ball to win.
The 8 pill and the 16 pill are 'free' pills. For instance, if you draw the 1, 8 and 16 pill then you would throw the 1 and win the break. If you then made a ball on the break and could see the 8 ball you would declare that "I am on the 8" and call the pocket, shoot the 8 ball in and win the game.
Strategy includes the idea that if your pills are made by another shooter and you come to the table with no shot on the 8 you do not declare yourself on the 8. You keep shooting the highest or lowest ball until you get a shot on the 8 ball and then you declare, show the pills and pocket the 8 in the called pocket.
This may be Kelly pool by another name. I have never played Kelly so I do not know.
