This game, rather its predecessor, is said to date back to 206 BCE to 220CE. It is also commonly known as Rochambeau. If you add a 4th element to the game, it is a double scissor (which looks like the Vulcan “live long and prosper” hand salute). It plays like the original scissor, but the “double-scissor” beats a single scissor. There is also a Dynamite gesture, basically a clenched fist with the thumb up in the air. But the World Rock Paper Scissors Association (this is for real) frowns upon its use. And those of you who are not nerds, there is the five-throw version: rock, paper, scissors, Spock, lizard. Spock is, of course, the “live, long, and prosper” gesture: it smashes scissors and vaporizes rock but is disproved by paper and poisoned by lizard. The Lizard is a closed fist with the thumb tucked inside: it poisons Spock and consumes paper but is killed by rock and dismembered by scissors. More recently there is the Double Fisted version of the game, played by more than two people who stand in a circle. Don’t forget the Strip RPS, the Street-Based RPS, the Point-Based RPS, and (unfortunately) the Corporal Punishment RPS. There is an online version where you can play with your friends AND one where you play against the computer. Are you ready?
