Puzzle Nintama Rantarou is one of those weird little Game Boy puzzle games that somehow sticks with you. It's based on the Japanese ninja school anime, so you get these tiny, pixelated ninja kids dropping blocks—kinda like Tetris but with way more charm. The music’s got that classic Game Boy bleep-bloop energy, and the blocks have these cute little faces that make losing slightly less painful.

At first, it feels simple—just match colors, clear lines—but then the speed picks up, and suddenly you’re frantically rotating ninja blocks while the theme song loops in your head. It’s not revolutionary, but there’s something oddly satisfying about it, especially if you’re into retro puzzlers with personality. Definitely a hidden gem if you can track it down.
