Shanghai on the Game Boy is one of those classic tile-matching games that’s way more absorbing than it has any right to be. You start with this layered stack of mahjong tiles, and the goal is simple—pair identical ones to clear them. But here’s the catch: you can only pick tiles that aren’t blocked on the left or right. Sounds easy, right? Until you realize halfway through that you’ve accidentally trapped yourself.

The controls are dead simple—just tap and match—but there’s something weirdly satisfying about watching the pile shrink as you chip away at it. The music’s got that classic Game Boy chiptune vibe, too, which somehow makes the whole thing feel more zen. I swear, I’ve lost track of time more than once just trying to clear one last level.

If you’ve ever played solitaire just to kill time, this is like that but with way more tile-flipping tension. It’s the kind of game you pick up for five minutes and suddenly realize you’ve been at it for an hour.
