Play Jankenman (Japan) Online
You play a dude who fights samurai and sumos in rock-paper-scissors battles that somehow feel as intense as a sword fight—complete with mind games and ridiculous frog-suited opponents. The pixel art and music nail that weird, nostalgic Game Boy vibe.

Jankenman came out on the Game Boy in 1991, developed by Hudson Soft. It was one of those quirky, experimental titles that felt right at home on the handheld, a system full of odd concepts and simple, engaging mechanics. You wouldn't call it a major release, but it had a distinct charm that made it memorable for anyone who stumbled upon it.
You control a hero who advances screen by screen, engaging enemies in rock-paper-scissors duels to clear your path. Your main objective is to defeat a series of themed bosses, like samurai and sumo wrestlers, by out-guessing their attacks. The combat relies on timing and prediction, turning a simple children's game into a tense battle of wits. The pacing is deliberate, almost methodical, as you learn patterns and anticipate moves. It feels surprisingly strategic for such a straightforward concept.
