This is a great, quick game!
Campers pair up and face one another. Each partner stands on one leg, while holding the other behind them with one arm.
The campers then try to push, pull, or trick the other person off balance. Each player should only make contact with the other player's free arm (not the one holding their leg) and no other parts of the body. Once a player place both feet on the ground, the other person wins. Each victory is worth one point, and the pairs can play up to 5 (or so points) before challenging a new partner.
This is a "Last Man Standing" version, where all players start in a small area at the same time and attempt to bump, pull, push others off balance and be the last person standing.
