Rules

The rules of Rock-paper-scissors-lizard-Spock are:

  • Scissors cut paper
  • Paper covers rock
  • Rock crushes lizard
  • Lizard poisons Spock
  • Spock smashes (or melts) scissors
  • Scissors decapitate lizard
  • Lizard eats paper
  • Paper disproves Spock
  • Spock vaporizes rock
  • Rock breaks 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.

One way to remember the rules is to remember the standard "rock-paper-scissors" ordering, where each gesture defeats the one before it, and is defeated by the one after. But then add the two novel gestures near the word they approximately rhyme with:

  1. Rock
  2. Spock
  3. Paper
  4. Lizard
  5. Scissors

In this expanded list, each gesture is defeated by the following two options, and defeats the preceding two.

Since the Spock gesture is known to be notoriously difficult for some people to perform, some players may be disadvantaged while playing this variant. The fingers must be moved quickly into the final position from a closed fist, which means that many people will not be able to use Spock, thus cutting down their options.

Famous quotes containing the word rules:

    “However patriarchal the world, at home the child knows that his mother is the source of all power. The hand that rocks the cradle rules his world. . . . The son never forgets that he owes his life to his mother, not just the creation of it but the maintenance of it, and that he owes her a debt he cannot conceivably repay, but which she may call in at any time.”
    —Frank Pittman (20th century)

    “However diligent she may be, however dedicated, no mother can escape the larger influences of culture, biology, fate . . . until we can actually live in a society where mothers and children genuinely matter, ours is an essentially powerless responsibility. Mothers carry out most of the work orders, but most of the rules governing our lives are shaped by outside influences.”
    —Mary Kay Blakely (20th century)

    “There are two great rules in life, the one general and the other particular. The first is that every one can in the end get what he wants if he only tries. This is the general rule. The particular rule is that every individual is more or less of an exception to the general rule.”
    —Samuel Butler (1835–1902)
