Play Shikakui Atama wo Marukusuru Advance - Kokugo Sansu Rika Shakai (J)(Independent) Online

Game Overview

Ever stumble across a game that makes you go, "Wait, was I just learning?" That's Shikakui Atama wo Marukusuru Advance for you. It's a GBA game that disguises Japanese, math, science, and social studies problems as these quick, satisfying puzzles—like someone took a textbook and turned it into a bunch of mini-games. At first glance, it seems like standard edutainment, but there's something weirdly addictive about the way it doles out little mental wins.

The math and logic stuff is totally playable even if your Japanese is rusty (mine sure is). I kept getting sucked into the rhythm of solving one more problem, just to see what quirky animation or reward popped up next. It’s got that old-school GBA charm—simple, colorful, and just the right amount of challenging without feeling like homework. If you’ve got a soft spot for retro brain teasers, this one’s a surprisingly fun way to kill time while pretending to be productive.
