Hiding from the ghosts

It feels like eons ago since I read the book “Ready Player One” but one key plot point was where the main character needed to play the perfect game of Pac-Man. He’d mentioned a hiding where the ghosts could not locate you. I’ve played Pac-man for decades and have never heard of such a thing. So I always assumed it was something made up for the book. I can officially confirm that it is infact a real thing. It’s thanks to an 8-bit math error and a rule where the ghosts can’t travel up in Pac-Mans spawn point. Check the video below for proof.
