Quoted from KingBW:I got 179mil today ... my highest so far. I saw for the first time at the end of the ball bonus total a 2x on 2 balls and a 3x on one ball pop up in a yellow circle on the ColorDMD then blow up the total end of ball bonus to a new total with that multiplier. Not sure what I did for that, but it felt like I accomplished something new after 8 months of playing every few days.
Sounds like you got the bonus doubler. You can get a separate multiplier by draining out an outlane when that lane is flashing. If you go down an inlane while the lane is flashing it doubles just your next shot where if you get it on an outlane it doubles the bonus. You can get multiples of this in one ball (collecting during MB) which can really blow up a bonus.
