I have no problem reaching the first I&S multiball. But no matter how many times I drop all the I&S targets and get the ball in the I&S hole, I can't reach the second one. The DMD just keeps saying "Shoot all drops to light."
I also tried removing the glass, dropping the targets by hand, and putting the ball in the I&S hole. I can do this multiple times in a row and it still says "Shoot all drops to light." I read Bowen's rulesheet and I think I'm doing it right, but I must be missing something. What am I missing?
