Hello, maybe someone could help me
A couple of years ago I wernt to japan for the first time with my friend and we wanted to try pachinko
We went to a parlour and had no idea wtf we were doing, we basically mashes all the buttons trying to get it to work and eventually a big warning sign came up on the screen, a red light on top started flashing and a fucking SIREN started sounding. We ran away.
Does anyone know what the fuck we did to cause that? I assume it was some kind of warning about damaging the machines but all we were doing it pressing the buttons that were there, we weren;'t shaking it or anything
Maybe we were about to win the jackpot or something
