Step 1: What you will need and how to play!
rock paper scissors are for the pokemon that have yet to evolve. the thumb wars are for the pokemon who have evolved once. the arm wrestling is for the pokemon that has evolved 3 times. every single battle your pokemon evolves (if it has won). you then have to find someone else who is on the same evolution as you and battle them. the person who wins is the person who manages to battle everyone and beat them at the last evolution!
Step 2: First evolution!
you can then pick from 3 pokemon, geodude, lotad or scyther. (rock paper scissors) which ever one beats the other gets to move up a rank. if you pick the same, nothing will happen. you will not be allowed to use that move for your next turn e.g if somebody used 2 geodudes at the same time they would only be able to pick lotad or scyther, and then they would be able to use the geodude again.
