You need a rope for that game.
The rope is strained across the room (or between two trees). The higher the rope is strained, the harder the game is, typical is a height somewhere between navel and chest of the players.
The group now has the task to pass the "wall". All members of the team have to get from one side of the rope to the other. They may not pass under the rope, but only above it (don't you see the wall below the rope?). They may not touch the rope, either. The group has to help is other somehow so that everybody can pass the obstacle.
- The game spider's net is quite similar, but needs more time to build up.
