An Expansion to Rock, Paper, Scissors that includes two new cards: Lizard and Scientist
Rock, Paper, Scissors (RPS) has been altered many times to include objects other than the traditional three. Circa 2004 a revision was made by Sam Kass and Karen Bryla to include a scientist (who is copyrighted) from a Sci-Fi TV series from the late 1970’s and a lizard and the mechanics of the game were altered to fit them in.
