Well he seemed a bit confused at one point ... "I don't know, I don't understand this game" to quote him.
I made a Visual Pinball recreation of this table some time ago (check it out !) so I've got a good grasp of the rules : they're not really complicated and are quite well covered in the various videos posted here.
A few things :
- the inlanes or the dead bumper that advance the bonus when lit are lit at random during the game (there's a switch to make it more or less frequent), usualy 2 out of 3, and will strobe between the 3 when the spinner spins. They will not be lit when you have to shoot the 8 or 9 target.
-the 8 target is tough to get by a direct shot, but you can reach it with a bank shot through the spinner (as well as the lock).
-shooting the spinner when the 9 target strobes through the eight lights will accelerate the rate of the strobing. Try your luck at getting the 9 by doing a bank shot through the spinner.
