Pinball Memories IWhen I went to college, there were virtually no video games; they were just starting out. I played pinball instead. My freshman year there were four machines in the game room; by the time I graduated there were at least 10. The machines were busiest after dinner when a lot of people would stop by for a quick game before heading back to the dormitories.
One of the first games I played at college was Jack in the Box, which was an interesting game because it had an exploit. If you look at the top of the machine, you'll see the ball comes down one of three rollovers. What you can't see from that angle is that it then falls into one of two kick-out holes on either side. Here's a top-down look at a schematic:
The trick was to give the machine a good nudge when it came out of the kickout hole and hopefully the ball would come out funny and instead of proceeding up and then out either side, it would fall back into the hole, collecting more points each time.
Aside from that the objective in Jack in the Box was to knock down the clown targets at the top of the field. If you got all ten down the game would give you either a special or an extra ball.
