A foul is anything (including the infractions below) that makes a shot illegal. It results in CB in hand to your opponent, where they can place the CB anywhere they want on the entire table (unless on the break, in which case it is ball in had in the behind the head string).

… based on the World Pool-Billiard Association (WPA) World Standardized Rules (the “official rules of pool”)

Important definitions:

  • legal shot: With a legal stroke and no foul, you must contact a legal OB and then something (CB or OB) must be driven to a cushion or be pocketed.
  • legal stroke: a single hit of the cue tip on the CB with a forward stroking motion of the cue stick.
  • foul: scratch, double hit, no foot on floor, ball driven off table, touching or interfering with balls, scoop, push, intentional miscue.
