All the players are blindfolded, the guide should ensure they can"t peek. Each guide should have about 2 players to guide around. (Anymore and it becomes hard to lead the blindfolded players as they need to be) Each guide is then given a map of the route they need to lead their blindfolded partners through, the route should be long enough so that the players are blindfolded for about 30 to 40 minutes and leads back to where they started. Once they have been taken on the walk, the blindfolded players have their blindfolds removed. Each is then given a large piece of paper and a pen and have to draw a map of the route they think they walked. They should include distances, landmarks anything else they think they passed. Once all the players have drawn their maps they are compared to one their guide had. Whoever draws the most accurate is the winner.
