Interesting ... I haven't read all the posts but I see no mention of taped boxes around the feet of pins ... at INDISC 2020 all the pins had a box outlined around the feet of the pin .. maybe gave you 2-3 inches in each direction .. if you moved/slide/lifted/juggled the pin out of the boxes you were DQ'd .. nothing to do with the tilt bob .. part of this is that people moving games around also changes the setup for the next player .. we implemented the taped boxes in our playoffs for the last season in early 2020 and will continue to use them going forward
