Janken, a verhetetlen kő-papír-olló robot - kamerája révén 1 milliszekundum alatt felismeri ellenfele választását, így az emberi szem számára észrevehetetlen módon, de valamivel a másik választása után dönt. Az eszköz olyan, gyors, hogy az sem működik, ha a játékos félúton meggondolja magát, mert a robot még időben észreveszi a turpisságot, és másik állapotot választ.
"I understand that Scissors can beat Paper, and I get how Rock can beat Scissors, but there's no fucking way Paper can beat Rock. Paper is supposed to magically wrap around Rock leaving it immobile? Why the hell cant paper do this to scissors? Screw scissors, why can't paper do this to people? Why isn't notebook paper constantly suffocating students while they take notes in class? I'll tell you why, because paper can't beat anybody, a rock would tear that shit up in 2 seconds. When I play rock/ paper/ scissors, I always choose rock. Then when somebody claims to beat me with their paper I can punch them in the face with my already clenched fist and say, oh shit, I'm sorry, I thought paper would protect you, you asshole."
