One volunteer can only press one person’s thumb down. This means that in total there should now be seven individuals with thumbs down, while the rest of the room still has their thumbs up. Volunteers should be as quiet as possible so as to confuse those with their heads down. [4] X Research source

Children who go guess after others who have guessed generally have an advantage, especially if one or more volunteers have been correctly eliminated. To make the game fair, the teacher can change up how the seven selected individuals are called upon to guess the person who touched their thumbs (e. g. , call students front-to-back, left-to right, or in alphabetical order, etc. ).
