If you’ve watched the hit TV series ‘The Big Bang Theory’, you might have heard the characters mention a game they play called ‘Rock-Paper-Scissors-Lizard-Spock’. This game is an interesting twist on the classic game of Rock-Paper-Scissors and was first introduced by the character Sheldon Cooper in season 2.

What is Rock-Paper-Scissors-Lizard-Spock?

Rock-Paper-Scissors-Lizard-Spock, also known as RPSLS, is a game that involves two players who each make a hand gesture representing one of five objects: rock, paper, scissors, lizard, or Spock. The rules of the game are as follows:

  • Rock crushes Scissors
  • 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

As you can see, the game adds two new objects: Lizard and Spock. These additions were made to address some of the shortcomings of the original game and to make it more complex and interesting.

How to Play RPSLS?

To play RPSLS, each player uses their hand to represent one of the five objects. For example, to represent rock, a player makes a fist with their hand.

To represent paper, they hold their hand flat. To represent scissors, they make a fist with their index and middle fingers extended.

Once both players have made their gestures, they reveal them at the same time. The winner is determined based on the rules outlined above. If both players make the same gesture, it’s a tie and the game is replayed.

Why Do People Play RPSLS?

RPSLS has gained popularity in recent years, especially among fans of The Big Bang Theory. One reason for this is that it adds an extra layer of complexity to the classic game of Rock-Paper-Scissors, making it more challenging and engaging.

Another reason is that it’s a fun way to settle disputes or make decisions. For example, if two friends can’t decide where to eat for lunch, they might play a quick game of RPSLS to determine the winner.


Rock-Paper-Scissors-Lizard-Spock is a fun and engaging game that has become popular around the world. Whether you’re a fan of The Big Bang Theory or you just enjoy playing games with friends, RPSLS is definitely worth trying out. So next time you’re looking for something to do, give it a try and see who comes out on top!
