Quoted from PantherCityPins:
For me, I’ve had problems getting through the 2 ball multiball part. I can hit the shots, hit the ring and then knock the ball out. I’ve done that a few times. It’s hitting the ring again without draining either ball that I’ve been stuck on.
It sounds like you are destroying the ring but not getting credit for it because the switch behind the ring is not working.
DTR is not a multiball. If the ball that is captured in the ring falls out of the front then it becomes a multiball by error which is a little unfortunate accident that occasionally happens because of the magnet design.
When DTR is set to 2-ball, you shoot the four shots, then shoot one into the ring magnet that is held, then the next ball is put into play from the shooter lane and you shoot that ball to knock the held ball out of the back of the ring/magnet which destroys the ring.
When DTR is set to 1-ball, you shoot the four shots and then shoot through the ring twice to destroy the ring.
