Hunt the Thimble (also known as Hide the Thimble) is a party game in which all but one partygoer leaves the room. The person remaining in the room hides a thimble, or other small object, somewhere in the room. When everyone comes back in, they must locate the hidden object.
In one variation, the thimble must be 'hidden' in plain sight from almost every part of the room.
Variations in which only one person leaves the room and everybody else hides the object include Singing Hunt the Thimble and Hot or Cold. In the singing version, the people who hid the thimble sing louder when the searcher is close to the object and softer when they are farther away. In Hot or Cold, the hiders tell the searcher what temperature they are based on proximity to the hidden object -- the closer they get, the hotter they are.
