there is a flaw in the application of the rule in this game. In both 9 - Ball (Texas Express, USPPA, and BCA) and 8 Ball (USPPA, APA, and BCA) the rules state a legal "hit" or touch on the players object ball "MUST" occur first, and then "SOMETHING" must touch a rail.
Meaning you need to make a legal hit on your object ball after which something must move to a rail, whether it be your suit in 8 ball, or the next ball in rotation for 9 Ball. (the cue ball, the object ball, or any other ball on the table must move to and contact a rail)
In the game, you can touch a rail first and barely tap an object ball and it counts as a good object touch as well as a rail touch.
I have been a BCA player for 3 years, both league in Washington State, and the BCA Open 9-Ball Tounament in Las Vegas.
(*NOTE* I dont know the rule as far as EUROPE and other Countries.)
