This website is an online version of the game 20 Questions. That’s the game often used in language classrooms, and long car trips, where one person thinks of a person, place or thing and the rest of the group has 20 chances to ask Yes/No Questions, trying to guess what that person is thinking of.
For instance, I might start by saying, “I’m thinking of a holiday.”
Q1: Is it an American holiday? → No.
Q2: Is it a Japanese holiday? → Yes.
Q3: Is it in the winter? → No.
Q4: Is it in July? → Yes.
Q5: Do people dress up in yukata? → Yes, some do.
Q6: Is it connected with the stars? → Yes.
… What would your next question be?
