At first thought, Pachinko seem to be like the Japanese version of the pinball except that it’s not. It is actually a cross between a slot machine and a pinball machine. You amass these balls and then you win and if you’re lucky you get trays full of them. Pachinko is fun and so addictive it should be illegal because people are gambling money away for that euphoric feeling of WINNING.
I found an article which teaches even FOTB gaijins proper Pachinko etiquette, and was rather amused at the matter-of-factly tone of the write-up. It’s serious business when it comes to Pachinko, don’t let the colorful lights fool you.
