20 Questions: Winning Strategies & Sample Questions

Core Strategy

• Start broad: "Living?" "Tangible?" "Person/place/thing?"
• Binary questions only: Yes/no maximizes info per turn.
• Narrow by category: Animal? Plant? Man-made? Abstract?
• Consider concepts: Emotions, ideas, events count.
• Listen actively: Each answer shapes the next question.
