Same rules. Everyone gets one go, in your one go you can only guess each person once. You can guess all of the people, but only one time :) First person to get one right gets that point, anyone that says it after... sorry :) If there is 1 person left undiscovered by the end of the day (So in 11 hours for me) I get 1 point. 2 people left, I get two points etc...
Just to clarify:
Picture 1 = Top left picture.
Picture 2 = Top right picture.
Picture 3 = Bottom left picture.
Good Luck to you all :)
