Most of us think of the game rock, paper, scissors as a game of chance.
Some of us, like Douglas Walker, co-author of the Rock Paper Scissors Strategy Guide, consider it a game of physical and psychological skill.
And then there are the scientists at the University of Tokyo's Ishikawa Oku Laboratory, makers of the Janken robot, who have turned the game into an impossible endeavor.
You cannot beat the Janken robot at rock, paper, scissors. The robot will always win.
Also, Janken is the Japanese name of the rock, paper, scissors game.
So how does the robot always win? The answer is simple: The robot cheats.
