How does 20q work
Answers (2)
Do you mean the game 20 questions? If you do, then one person chooses a thing in their mind (for example, basketball). The other people have to ask Yes-or-No questions to find out what the thing is. For example, they can ask "Is it round?" or "Is it soft?" (person thinking of the basketball says "Yes" or "No"). They can only ask 20 questions in total.
It compares your answers to the answers of other people to derivate what you may be thinking of. As it starts narrowing things down, it asks more and more pertinent questions to either the thing you are thinking of, or the thing it thinks you are thinking of.
Just as the same as the game works in real life.
