I used to own a pachinko machine and had hours of fun playing it, but sadly the Dolphin Paradise game really doesn’t come close to it.
TBH I would say this is the kind of game that won’t translate well to the screen.
The little balls plinky plonking down through the nails while some gaudy dressed panda bear dances across the LCD singing in Japanese just doesn’t seem to feel the same on a flat PC screen.
The money is retarded in Japan. Interesting history behind it involving Yakuza and North Korean Mafia, oops, maybe I’ve said too much 
Alex, I’d keep the domains though, you never know, esp with Pachi-slo being so slot-similar and the 2nd hand Pachi-slo market is quite big in the States (check eBay)
