The Bank Shot shows the extra balls earned on the backglass as yellow WOWs that light up each time you earn one. The "balls to play" light indicates how many you still have....after the ball in play drains, a WOW light will go out & the "balls to play" should stay on the same #. Am having one related issue with mine, if score is achieved to earn a WOW during the bonus points being awarded (upon ball drain), I get the "knock" to earn a WOW, but before an additional ball is awarded, the game ends. Need to fix that.
