When the bully who goes after Brad pulls the plug on the video game; he would have erased all the scores stored in the machine.
Tim didn't need a strike to win he just needed 10 pins which can be done in two shots. After his foul he would have had a second shot and still have a chance to win.
After Tim bowls his first frame and scores a 1, Jill bowls two frames in a row (where she scores two strikes). They should instead have bowled alternate frames.
At the end of the bowling match a boom mic drops into the frame.
