So I have two pachislo in my collection now.
First was my 2011 Street Fighter IV from Enterrise.
A week ago, I added a 2012 game from Star called 2027 Revise.

In that time, I've cycled through roughly 3,000 spins on the two machines and have not experienced a single hit worth more than 14 credits.
I've adjusted the skill level from 1 to 6 on both machines and can confirm special events come up more frequently on both machines when set to 6.

Getting the big hits really does seem to be a skill thing though. I figured by now, I would have gotten at least one big hit on the machines but it's just bells and free spins.

Does anyone have any tips for getting those magical 7s to land when you hit the button? This feels more like a skill thing than a luck thing with how quickly the reels stop.
