Egg to Superhero

This game is like a large scale rock, paper, scissors tournament. Every participant starts out as an egg with their hands above their head peeping like a chick. When they encounter a fellow egg they play rock, paper, scissors. The winner gets upgraded to a chicken and begins flapping their wings and clucking around the room while the looser remains an egg. The same scenario plays out when two chickens meet, except the winner now become a dinosaur. When two dinosaurs battle it out with rock, paper, scissors, the winner becomes a robot. When two robots battle the winner becomes a superhero and when two superheroes battle the winner moves out of the playing field. The winners are the first superhero out and the remaining players stuck in each level of the game when everything is done.
