A bowler must wait until all wood has halted motion under penalty of foul. However, if the wood has apparently stopped rolling and then starts rolling again while the player is in the act of delivering the ball, or while the ball is in motion, there shall be no penalty. The bowler resets and is entitled to three balls in the frame. Bowler is credited with making fair contact. Bowler knocks down nine pins with the first ball.
Second ball is fairly delivered but before making fair contact, pin falls.
Bowler is credited with spare.
