WPA — World Pool-Billiard Association
The world governing body of pool.
World Standardized Rules, 8‑Ball, Rule 3.3 "Break Shot": a scratch on the break is a foul — the incoming player takes cue ball in hand behind the head string. Even pocketing the 8 while scratching isn't a loss: the 8 is spotted or re‑racked. Rule 3.8 "Losing the Rack" lists every way to lose a game, and scratching on the break is not one of them.
