RPS Lizard Spock expands the classic Rock Paper Scissors with two additional choices, creating a richer and more balanced game of prediction. Invented by Sam Kass and popularized by The Big Bang Theory, this five-way showdown adds Lizard and Spock to the original trio. Each choice beats exactly two others and loses to two, reducing the chance of ties while increasing the strategic possibilities. The AI opponent studies your patterns and adapts, so predictable play is punished quickly. With ten possible outcomes per round instead of the original six, reading your opponent and disguising your own tendencies becomes a genuine skill. Statistics and streak tracking help you analyze your performance over time.
