Play Sansuu 5 & 6 Nen - Keisan Game (Japan) (Beta) Online
Mash buttons to solve math problems against the clock—starts easy with multiplication, then suddenly you're sweating over fractions while upbeat chiptunes mock your mistakes. Pure NES pressure.

Ever played one of those old-school educational games that somehow makes math weirdly addictive? Sansuu 5 & 6 Nen is exactly that—a Japanese NES game that turns multiplication and division into a frantic race against the clock. At first glance, it looks like a basic drill game, but after a few rounds, you’ll catch yourself leaning forward, mashing buttons like you’re in an arcade.
The problems start simple (good for warming up), but soon you’re juggling fractions and percentages while a chiptune soundtrack eggs you on. It’s got that classic NES charm—no tutorials, no hand-holding, just you versus a stack of equations. I definitely botched a few early rounds before getting into the rhythm.
If you’re into retro games or just want to dust off your mental math, this one’s a hidden gem. The beta version feels a little rough around the edges, but that just adds to its weird appeal. You might not understand the Japanese text, but numbers are universal—and so is the urge to beat your last high score.
