So this is one of those old-school Game Boy mahjong games—specifically, Nada Asatarou no Powerful Mahjong. It’s Japan-only, so if you don’t read Japanese, expect some guesswork with menus. The gameplay itself is straightforward tile-matching, but the AI can be surprisingly aggressive for a handheld title from back then.

First thing you’ll notice? The chunky pixel art and those satisfying tile-click sounds. It’s got that classic GB green-tinted screen vibe, which honestly adds to the charm. There’s a "100 Challenges" mode that throws different scenarios at you—some are brutal, others feel almost too easy. No idea who Nada Asatarou is, but his name’s on the box, so he must’ve been a big deal in ’90s Japanese mahjong circles.

If you’re into retro mahjong sims, this one’s a solid time-killer, though you might want a guide handy for the kanji. The music loops fast, so maybe keep the volume low after a while.
