"Machine seems to be set up to have a three ball multiball, but badly. It does "partial optical link" with both balls in the hole, and pushes out a third ball. But once you drain two out of the three balls, it ends the ball and kills the flippers." The Machine: Bride of Pin-Bot (Williams, 1991)
"Entering the “lair” behind the upper left flipper does not register when shot is hit. Middle ramp that can be hit from upper left flipper also does not register shots." Teenage Mutant Ninja Turtles (Pro) (Stern, 2020)
"The scoop is now a mess. It shoots the ball directly down the middle and drains it about half the time. Don’t try getting the extra ball…." Ghostbusters (Pro) (Stern, 2016)
