Really simple game this.

Equipment

Blindfolds (or sleep masks).
Reasonably large room.

How to play

  1. Split the players up into groups of 2 or 3
  2. Assign each group an animal which makes a distinctive noise (cow, dog, cat, sheep, lion, etc)
  3. The players put on the blindfolds, and the leaders then turn them around and move them around the room
  4. On “Go”, the groups of 2 of 3 have to find the rest of their group purely by making the animal noise

And that’s it. Really funny (especially if you’re a leader).
