Here's how you play:
Everyone starts out with a certain number of pennies and stands (or sits) a determined distance from a wall. One at a time, each person flicks a penny off of their thumb. When everyone has pitched their pennies, all rush forward to see whose penny is the closest to the wall. That person wins all of the pennies. Play continues like this until one person has all of the pennies and is the winner.
When I was a teacher I used to play this game with a slight variation. The way the students earned the pennies to play with was by answering review questions correctly. That way the students who answered the most questions had the best chance at winning, but it was still fun for the others.
