Rock Paper Scissors Lizard Spock in Minetest

Mesecons creation that allows you to play Rock Paper Scissors Lizard Spock in Minetest! 




Rock-paper-scissors-lizard-Spock is a five-gesture expansion of the classic selection method game rock-paper-scissors. It operates on the same basic principle, but includes two additional weapons: the lizard (formed by the hand as a sock-puppet-like mouth) and Spock (formed by the Star Trek Vulcan salute). This reduces the chances of a round ending in a tie. 


The rules of Rock-paper-scissors-lizard-Spock are:
  • Scissors cuts paper
  • Paper covers rock
  • Rock crushes lizard
  • Lizard poisons Spock
  • Spock smashes scissors
  • Scissors decapitates lizard
  • Lizard eats paper
  • Paper disproves Spock
  • Spock vaporizes rock
  • Rock crushes scissors
There are ten possible pairings of the five gestures; each gesture beats two of the other gestures and is beaten by the remaining two.
