Quoted from TreyBo69:Flash is really underrated here. It's hard to fully appreciate just how important that design was. It helped saved Williams who hadn't had a sales hit in a while, I think it created the cross playfield plunge or at least really popularized it, it was an early example of a repeatable loop shot from an upper flipper that shows up on so many later Ritchie games (protip: upgrade your flippers to later system 11 designs to really pop off some loops), it introduced flash lamps and background noise to pinball, and is frankly still a pretty fun game overall. The only thing you can really ding it for is the art is very meh and the background noise did not age well (defaults to off for a reason)
Flash is one of those layouts that you can see it so many other games made later, like Skateball and Blackout. It really is one of his all time great layouts that influenced countless other games.
Steve liked to cherry pick cool ideas from other games and I think he probably got that cross plunge from games like 4 million BC, but yes it certainly made it a popular feature.
Flash is a great game for sure and you still see plenty of new games that borrow its elements (even if most of them are Steve Ritchie games lol)
One of the best spinner rips in pinball. I also like to light the pop bumpers early in each ball with the lower left standup - an unexploited source of points that many people disregard.
