Play Sansuu 4 Nen - Keisan Game (Japan) (Beta) Online
You race against a ticking clock solving math problems in Japanese, weirdly getting hooked as the tempo picks up and that chiptune soundtrack pushes you to beat your last score.

Sansuu 4 Nen - Keisan Game (Japan) (Beta) is one of those weird little NES games that makes you go, "Wait, why am I actually enjoying math drills?" It’s all in Japanese, but the numbers don’t lie—you’re basically racing against the clock to solve equations while this cheerful 8-bit soundtrack nudges you along.
At first, it feels like homework, but then you realize you’re leaning forward, gripping the controller tighter as the problems speed up. There’s something oddly satisfying about nailing a tricky division problem just before time runs out. The pixelated graphics are simple, but they’ve got that warm Famicom vibe—like someone took a classroom chalkboard and turned it into an arcade game.
If you’ve got a soft spot for retro edutainment or just want to see how Japanese kids in the '80s practiced math, this one’s a fun curiosity. Just don’t be surprised if you catch yourself muttering multiplication tables under your breath afterward.
