Dr. Smile

Dr. Smile is a one card microgame. The card shows eight facial expressions. One player plays the role of the evil Dr. Smile, who has locked up the players in metal cylinders so the only thing they can move is their faces. Dr. Smile secretly defines a sequence of three such expressions (or more, for a more challenging game).

Players stand in a a row in front of Dr. Smile and take turns making one of the expressions, with Dr. Smile moving his/her head when it is correct. From the second round onward, the second expression must also be guessed, and so on. The goal is to find out the complete sequence in order to escape from the evil doctor.
