Akagi (J)(Caravan) is one of those weird little GBA titles that slipped under the radar—it's a Japanese mahjong game based on the Akagi manga. If you're into riichi mahjong, it's actually pretty solid, though the interface feels a bit cramped on the tiny GBA screen. The AI isn't pushover-level either—expect some brutal hands if you're not careful.

No English patch exists (yet), so you'll need to know your kanji or have a translation guide handy. But if you can push past that, it's got that addictive "just one more round" vibe. The caravan mode is where it shines, throwing increasingly tough opponents at you.

Definitely niche, but if you're the kind of person who loses hours to tile-based gambling drama, this might be your next time sink.
