Perfect Stranger PERFECT STRANGER is the ultimate party game. Read a question card, place a YES or NO card face down in the center, then everyone guesses how many YES or NOs are in the pile. Reveal the answers to see who won! Questions are broken into three fun categories: Hypothetical, Philosophical, and Etiquette — all ranging from hilarious to thought-provoking. Add action cards and bonus rounds to make the gameplay even more dynamic.
