Sinking ship
The key to success in any project is a proper strategy in addition to good teamwork. The rules of this game are deceptively simple. The entire group must find a way to occupy a space that shrinks over time and use creativity to fit all the whole group in the continuously shrinking space. A boundary represents the ever shrinking space and can be a rope, a tarp or blanket being folded over or even small traffic cones. The most creative wins.
