Play Gakkou no Kaidan : Hyakuyoubako no Fuuin Online

Gakkou no Kaidan: Hyakuyoubako no Fuuin came out for the Game Boy Advance in 2004, developed by Sunrise Interactive. It was part of that wave of Japanese horror games that tried to bring spooky stories to handhelds, leaning into the hardware's limitations to build atmosphere rather than spectacle. You don't get big cinematic scares; it's more about mood, the kind of game you play late at night with the sound up.

You control a student trapped inside their school after dark, exploring room by room to uncover the mystery of a sealed box and the spirits tied to it. Movement is screen by screen, with each new area presenting puzzles, hiding items, or concealing a ghost you must avoid or pacify. There's no direct combat; you use found tools like a camera to repel threats or holy water to cleanse areas, which makes every encounter tense since resources are limited. The pacing is deliberate, sometimes slow, and the difficulty comes from managing your fear as much as your inventory. It feels like holding your breath while turning a corner, never sure what you'll find.
