I start off by throwing 15 balls on the table and leave them pretty much the way they were thrown out, unless some were pocketed when thrown out. I pull up the ones that were pocketed and then start shooting them. If I miss a ball, I throw them all back up and start over. Once I've run the 15, I start another game. I throw the 15 balls back up but I make sure there are no clusters and no balls are touching the rails. I run these without letting the cb touch the rail. If I miss or the cb touches a rail, I start over. After I win this game, I play 9 ball in a similar fashion. I throw the 9 balls up and take ball in hand and try to run out. Once I run a rack, I start playing the Ghost, i.e., I break the 9 ball rack and take ball in hand following the break and try to run out. Whenever I run out, that's a game for me. Whenever I miss a shot, the Ghost wins. This practice routine can last as little as an hour or as long as I want to play depending on how good or bad I'm playing.
