Rock-paper-scissors-lizard-Spock

Rock-paper-scissors-lizard-Spock is a variation of the standard game which includes the addition of two new gestures, the Lizard and Spock, and was invented by Sam Kass. Due to the usage of five gestures instead of three, there are ten possible pairings, reducing the chances of a round ending in a tie. The game initially didn't receive much attention nor usage. This increased when the game was mentioned in three episodes of the popular tv-series The Big Bang Theory. According to an interview with Kass, the series producers did not ask for permission to use the game. Kass was later referenced in an episode in the fifth season as the creator of the game (shown below).

The game launched a kickstarter campaign on February 5th, 2013, by Alien Lab called Geek Dice. Instead of the standard hand-gesture variation of the game, in Geek Dice all players simultaneously throw a dice on which each side represents one of the gestures from rock-paper-scissors-lizard-Spock. The roll of the dices decide the outcome of the game, and if the players want to can result in the winning or losing of playing chips. The Kickstarter eventually reached its goal of $15,000 on March 18th.
