Mushi-ken: frog, snake and slug

Mushi-ken (虫拳) is one of the oldest Japanese hand games and an ancestor of janken. Instead of rock, paper and scissors it has three animals: the frog eats the slug, the snake eats the frog, and the slug's slime melts the snake.

How to play Mushi-ken

  • Both players show an animal at the same time.
  • The frog (thumb) eats the slug.
  • The snake (index finger) eats the frog.
  • The slug (little finger) melts the snake.
  • Same animals are a tie: show again.

Where Mushi-ken comes from

Hand games like it came to Japan from China and were popular by the Edo period. Mushi-ken's circle of three, in which every hand beats one and loses to one, is the idea janken was later built on.

Playing Mushi-ken on Janken

Mushi-ken plays exactly like janken with the animals in place of the hands, so everything you know about rock paper scissors still works. Play it against a bot or online, to the best of 1, 3 or 5. Mushi-ken games are casual.
