Rock Paper Scissors is a child's game. But it's more than that if you can believe it, and it has a pretty cool history as well.

# Summary

In this episode, Josh and Chuck dive deep into the deceptively simple world of rock, paper, scissors—exploring how a children's game has hidden complexity that extends all the way to professional tournaments and game theory. Starting with a fun story about a Japanese executive who hired twin girls to play the game for a $20 million art collection auction, the hosts trace rock, paper, scissors back through its origins in ancient China and Japan, discovering it's part of a much larger family of hand-throwing games with creative variations like frog versus snake. They then venture into the surprisingly serious realm of game theory, conditional responses, and the psychological strategies actual tournament players use to gain competitive advantages, proving that beneath this seemingly random game lies genuine strategic depth that has captivated mathematicians and competitors alike.
