Back in 1980 two mates and I would skip class for the afternoon to play pins (those two still come round regularly and play my collection!) If money was tight (and it usually was) I'd play a game on Time Warp. I could usually gain the three credits on the way to high score, then the three for high score. We'd manage the afternoon from then with what else we'd win. The problem was working out the collected bonus and making sure you dropped all remaining balls so it would finish within the gap between the current high score but before clocking over. I remember starting this when the HS was around 950,000, and that gap getting smaller and smaller, until the HS was 998,000 odd, and that was the end of getting the three extra credits! Lucky it was also about the end of the school year.
I still try the same thing on my Time Warp I now have - she's sitting at about 996,000 :)
