Play Jankenman (japan) Online

I first came across Jankenman on the Game Boy back in 1991, a release from Hudson Soft. It was one of those many portable titles that appeared during the system's early years, a puzzle action game built around the simple concept of rock paper scissors. You don't see many games trying to make a full adventure out of that idea.

You control a little character navigating single screen rooms, and every enemy is defeated not with a weapon, but by winning a round of rock paper scissors against them. The main goal is to work your way through the stages, clearing each area of these RPS opponents. The core mechanics involve predicting the enemy's next throw and countering it correctly; if you lose, you take damage. You explore the stages room by room, and there is a strategic element in choosing which enemy to challenge next, as they often block your path. The game can feel quite difficult because a few wrong guesses will end your run quickly. It creates a tense, almost nervous feeling as you try to outthink each opponent on the screen.
