Play Gem Gem (Japan) Online
You match falling gems before they stack up, and there's something weirdly satisfying about how they pop when you clear a line—simple, but it hooks you fast. The music's pure Game Boy charm, and it hits that sweet spot between Tetris and Puyo Puyo.

Gem Gem is a puzzle game released for the Game Boy in Japan, developed by a small team whose name doesn't often come up in conversation. It arrived during a time when the handheld was crowded with falling block games, but it managed to carve out its own quiet corner without much fanfare.
You control a cursor to swap adjacent gems, aiming to match three or more of the same color before the stack reaches the top of the screen. The main objective is to survive as long as possible while the gems drop faster and faster. Two key mechanics include the ability to trigger chain reactions by planning matches under falling rows, and a subtle gravity effect that causes gems to settle after a clear. The pacing starts relaxed but quickly becomes demanding, requiring quick decisions to avoid a game over. It feels focused and just difficult enough to keep you coming back for one more try.
