Ever tried pachinko but had no clue what you were doing? This old Game Boy Color guide is basically a cheat sheet for those flashy Japanese pinball machines. It breaks down the odds, payouts, and strategies for different pachinko parlors—kinda like having a seasoned gambler whispering tips in your ear.

The menus are all in Japanese, but if you’ve got patience (or a translation app), there’s some weirdly specific data here. Like, which machines have sneaky tilt mechanisms or how long to nudge before the attendant side-eyes you. Not exactly thrilling gameplay, but if you’re into retro gambling vibes, it’s a niche time capsule.

Honestly, half the fun is imagining some salaryman in 1999 frantically studying this on his commute.
