About This Game

Please note: this game is in Japanese only

All text, menus, story dialogue, voices and, most importantly, all quiz questions and answers are in Japanese. There is no English translation. Many questions test knowledge of Japanese language, history, culture, anime, manga and games, so the game is best suited to players who read Japanese comfortably.

Spin the roulette through one year of campus life

Kirameki Quiz: Stargazer Hill Diary is an arcade-style quiz game wrapped in a light romance story. Move across a 365-day calendar board by stopping the roulette at the right moment, choose your route, and meet ten distinctive heroines in the college town of Hoshimigaoka, "Stargazer Hill." Beat them in trivia duels, grow closer, and head toward one of 13 endings.
