Play Hayaoshi Quiz - Ouza Ketteisen (Japan) Online
Your thumbs cramp up smashing the A button as trivia questions fly at you—miss one and it’s over. That panic when you blank on an easy answer while the timer ticks down? Pure adrenaline.

Hayaoshi Quiz: Ouza Ketteisen came out for the Game Boy in 1991, developed by Irem. It was part of that wave of Japanese quiz games that tried to translate the frantic energy of TV game shows onto a handheld screen, a niche but memorable corner of the platform's library.
You play as a contestant answering rapid-fire trivia questions across categories like history, science, and pop culture. The main goal is to answer correctly and quickly to climb the ranks and become the champion. The game uses a strict timer for each question, deducts points for wrong answers, and throws in sudden death rounds where one mistake eliminates you. The pacing is relentless, and the difficulty can spike without warning, especially if your knowledge of early 90s Japanese culture is rusty. It feels like being put on the spot in a real quiz showdown, where every second of hesitation costs you.
