Winners of rounds have their opponents link up with them until one remains.
All the players find a partner and play rock paper scissors. Whoever loses must put their hands on the should of the winner, forming a train.
The front person of that train leads their train to another train and the front people of each train play against each other. The train that losses attaches to the back of the winning train.
This continues until only one train remains.
