Hayaoshi Quiz - Ouza Ketteisen is one of those classic Japanese quiz games for the Game Boy that feels like a fever dream if you don’t understand the language. You’re thrown into rapid-fire trivia rounds where speed matters just as much as knowing the answers—except, well, good luck if you’re not fluent in Japanese. The questions cover everything from history to pop culture, and the buzzer mechanic keeps it tense.

Visually, it’s pure late-'90s Game Boy charm—simple menus, chunky pixel text, and that satisfying blip sound when you nail an answer. If you’re into retro trivia or just curious about obscure Japanese games, this one’s a quirky time capsule. Just don’t expect to win without a translator handy.
