Shanghai Pocket is one of those weirdly satisfying Game Boy Color puzzle games where you're basically playing mahjong solitaire—you know, matching those ornate tiles to clear the board. The Japanese version has this oddly calming vibe with its little chime sounds when you make a match, and the tiles have that classic hand-painted look. At first, I kept getting stuck because I wasn’t paying attention to which pieces were actually free to grab, but once you get the rhythm, it’s weirdly addictive. Perfect for killing time on a train ride or when you just need something to zone out with. The music’s low-key enough that you won’t get sick of it after an hour, either.
