Shikakui Atama Wo Maruku Suru is one of those Game Boy puzzlers that looks simple at first—just slot shapes into a grid—but gets sneakily tricky after a few levels. The first puzzles lull you into thinking you've got it figured out, then suddenly you're staring at this weird L-shaped block wondering how the heck it fits without leaving gaps.

What I like is how it makes you rotate pieces in your head before committing. Sometimes the solution seems obvious until you realize you've trapped yourself with no space left. The music's got that classic Game Boy bleep-bloop charm too, which helps when you're stuck on the same puzzle for ten minutes.

It's the kind of game where you tell yourself "just one more level" at 1 AM. The later stages introduce these jagged pieces that feel impossible until they click into place perfectly. That moment when the last block fits? Pure satisfaction.
