For those who have not seen The Big Bang Theory season 2 episode 8, Rock-Paper-Scissors-Lizard-Spock (RPSLS) is a branch of the classic Rock-Paper-Scissors game with the two obvious additions.

I was originally too quick to give the show’s creators, Chuck Lorre and Bill Prady, credit for the creation of the game, learning recently that it was actually invented by Sam Kass and Karen Bryla.

For a party this year, I designed an expansion pack of cards to mix things up even more. Each card either trumps one of the rules, or restricts the opponent.

*If you have one of these cards, you must tell the opponent before initiating play.

Party Game Rules

1. You get five blank challenge cards, and one of the above special cards upon arrival to the party
2. Over the course of the evening, you (the challenger) can challenge another attendee (the defender) to three consecutive games of RPSLS.
• Either player can use a special card to affect play.
3. If the challenger loses two out of three games, they forfeit one of their challenge cards to the defender.
4. If the challenger wins two out of three games, they collect one of the defender’s challenge cards.
5. The challenger and defender swap special cards at the end of the round.

At the end of the evening, each attendee writes their name on the back of all their collected / remaining challenge cards and submits them for the prize draw.
