Why not have a rock paper scissors tournament.
This is fun and loud energizer game based on the well-known “Rock, Paper, Scissor” game. People play against each other in pairs until the first win. But instead of the losing players becoming eliminated from the tournament, they become a fan of the winner, and they cheer for them as the winner plays against a new opponent. We repeat the process until there are only two players left.
Winner get s a gift !
