The game didn't run much longer than a typical game, although I had two or three free balls in total. A good portion of the points (around 100 million of them) come from a huge bonus at the end of the final ball. I had a 4X bonus already from ball 4, then from the urban informant got a +5X bonus and then a hold bonusX; the final bonus for ball 5 was x9 for a hundred million or so.
If one could manage to get these types of end bonuses by ball 1 or 2 (as opposed to the final two balls like I did), then they'd have a chance to beat this score.
I haven't played this in a long while.

After getting 98 mil when I played it the other day, I tried again and got the 231 mil hi-score yesterday.
