This classic, no set-up, game is a big hit with all age groups.  I’ve used it for everything from family home evenings to combined mutual activities.  It’s a classic.

Set Up:
Divide your group into two teams of any size (recommended minimum is 4 per team).   Gather 5-10 blankets, sheets, or sleeping bags.  You’ll need one neutral person to act as a referee and be the blanket coverer.Objective:
To acquire the most points in a pre-determined number of rounds.  Points are acquired by tricking the other team into thinking there are more or less team members under the blankets.  How to Play:
Instruct the first team to go to a separate room.  The remaining team has three minutes to create a structure with any number of team members.  For example, two people stand in the center and form an arch with their arms.  Other team members hide around their legs.  The referee then covers the entire structure with blankets.  Any remaining team members not under the blankets hide in or near the room.  The referee then calls the other team in.  They are not allowed to touch the blankets.  They have two minutes to make an official guess.  Once they’ve agreed on a number, the referee announces it and the team comes out from under the blankets.Scoring:
If the team guessed the correct number of people.  They earn 3 points.  For every number they’re off (either high or low), the opposing team gains a point.  The team with the highest point total at the end of the game wins.
