20 Questions

  1. Jul 30, 2013 #1
    I recently learned about this old game, 20 Questions. In this game, one of the players, the Answerer, thinks of an object, a common noun, and other players take turns to ask Yes/No question to him. Like, Is it less than 2kg ? , Does it run on electricity, Is it worth over 1000$? etc. If they figure it out with less than 20 questions, the Askers win, otherwise the Answerer wins. The person who finally figures it out got to be the next Answerer.
    I tried playing this game with my brother (I asked all 20 questions) but found it incredibly hard to come-up with good questions. It was also because I needed to keep track of all my questions and answer in my head.

    Why don't people play this intelligence demanding game here? This game suits PF :) .

    I know this game! the only difference is you only have three questions to ask instead of twenty. :biggrin:

    Why don't you start the game, I_am_learning? :smile:

    OMG, How would one find out by asking only 3 questions? I am not able to, even by asking 30 questions. That's why I didn't want to start (and play) the game myself (I am too poor). I just wanted to see intelligent folks play it. :).

    Ok, I can do the easier task. I am the Answerer. I have thought of an object. You can now start asking questions. Go on. :)

    There's a small handheld "toy" called "20Q" (a stronger version of the software is online at www.20q.com) that plays this game remarkably well. My nephew played it while I observed him, and by the time 20Q asked him if it was "green and wrinkly," both the game and I knew he was thinking of a booger. Adorable kid ...

    To stay on topic, is it smaller than a microwave oven?

    a T.V ?

    No. But this is not how you play. You need to keep narrowing the field, not make wild guesses.

    i did narrow the field,
    and it wasn't a wild guess, i guess from the existing questions.

    Is it used in the home?

    Is it used in transportation?

    Is it used solely for transporting people?

    OK, we might have picked a better midpoint for our binary search lol.
  24. Aug 2, 2013 #23
    This determines if it is used to transport goods or not. It's actually helpful, and we still have plenty of questions.
  25. Aug 2, 2013 #24
    I predict that it transports both, and that the ultimate answer is, something very close to a car. Or a bicycle. Or a scooter. I had a Strategy, damn you! lol

    Is it a land transport
