Pizza or Chinese? Movies or video games? Our lives are full of difficult decisions. And one of the most tried-and-true methods for making those tough decisions is a quick game of Rock Paper Scissors, also known as Roshambo.

But for some, Roshambo is more than a way to decide who gets to eat the last French fry. It’s more than just a game–it’s a lifestyle. For these street-wise warriors, the spirit of Roshambo is in the air they breathe, the clothes they wear, and the words they speak. They don’t just play Rock Paper Scissors; they play Roshambo Rumble.

This game was created from start to finish in one 40-hour work week in 2016 as a personal game development challenge.
