Play Sansuu 3 Nen - Keisan Game (Japan) Online

Okay, so Sansuu 3 Nen - Keisan Game looks like one of those dusty old educational NES games at first glance—but trust me, it’s weirdly fun. You’re basically doing third-grade math drills (addition, subtraction, the usual), except the 8-bit presentation and ticking clock turn it into this weirdly tense little challenge. The music’s got that classic Nintendo pep, and before long, you’re muttering times tables under your breath like it’s a high-speed puzzle game.

It’s not flashy, but that’s the charm. Just you, some simple equations, and that satisfying *blip* when you get one right. I’d be lying if I said I didn’t get competitive with my own high scores. If you’ve got a soft spot for retro edutainment or just want to test your mental math without feeling like you’re back in school, this one’s a surprisingly good time.
