Give each youth a wrapped sucker at the start of the game. Tell them they can’t eat them or unwrap them until the game is over, but they will have an opportunity to earn more suckers in this game. They can get another sucker by telling a story to the group. If they talk while someone else is talking (other than for encouragement) or if they repeat a story or idea that someone else had, they have to give the speaker their sucker.
This encourages group sharing and understanding. This can be used to just plain get to know each other, to review ideas (they can try to stump the leader about material covered by asking questions. No one can repeat a question asked already, so they have to listen to each other), to make up stories, to retell Bible stories…. Suckers are very motivating!!
