Jongbou is this weird little Famicom gem that mashes up mahjong with block-breaking—like if Arkanoid and your grandma's favorite tile game had a baby. You're clearing tiles by matching pairs, but there's this bouncing ball wrecking everything too. Classic SNK strangeness, and yeah, it's Japan-only, so expect some kanji confusion at first. The music's got that crunchy 8-bit charm, and the whole thing feels like someone dared the devs to make mahjong chaotic. Definitely one for the "wait, this exists?" corner of your retro collection.
