Janken is "rock, paper, scissors," Japanese-style. The rules are nearly identical to the American (or perhaps world?) game. Two players count ONE, TWO, THREE, GO while pumping their fists. On GO, the players show a fist ("rock"), index and middle fingers extended in a V ("scissors"), or palm flat and facing down ("paper"). The exchange is won as determined by the singsong rules:
  1. Scissors cuts Paper!
  2. Paper covers Rock!
  3. Rock breaks Scissors!

The internet is clogged with on-line and stand-alone versions of this game, written in Flash, Java or Javascript, etc.
