    A random yes or no, right now

    Stuck between going to the gym and ordering takeout? Let this Yes or No generator make the call. Type your question if you like, press “Ask”, and the answer fills the screen: YES or NO. Think of it as a coin toss you can read from across the room.

    Every answer is drawn in your browser using its cryptographic random number generator. Your question stays on your device: it is never sent anywhere and never saved.

    How to use it

    1. Pick a mode: “Yes / No”, “Yes / No / Maybe” or “Magic ball”. Your choice of mode is remembered for next time.
    2. Type your question in “Your question (optional)”. It appears above the answer.
    3. Press “Ask”, hit Enter while in the question box, or tap the space bar.
    4. Tick “Best of 3” if you want the first answer to come up twice to win.
    5. Check “Your last 10 answers” and the yes and no tally below. “Reset” clears both.

    The exact odds

    In “Yes / No” mode, each answer has a 1 in 2 chance, exactly 50%. In “Yes / No / Maybe” mode, each has a 1 in 3 chance, about 33.3%. No answer gets even a tiny edge.

    “Best of 3” keeps the odds the same: yes and no still have a 1 in 2 chance each. What changes is the drama. With two answers, the contest ends after 2 draws half the time (yes-yes or no-no) and after 3 draws the other half. With maybe in the mix, each side still has a 1 in 3 chance, and it can take up to 4 draws: 2 draws in 1 case out of 3, 3 draws in 4 cases out of 9, 4 draws in 2 cases out of 9.

    The “Magic ball” picks from 20 classic replies: 10 positive ones such as “It is certain.”, 5 non-committal ones such as “Ask again later.” and 5 negative ones such as “Very doubtful.”. That gives you a 1 in 2 chance of a yes, 1 in 4 of a no and 1 in 4 of a dodge. In the tally, positive replies count as yes, negative ones as no and the rest as maybe.

    Ask 100 questions and you probably won't see exactly 50 yeses. Anything from about 40 to 60 is perfectly normal.

    Ways to use it

    • Settle who takes out the trash or does the dishes tonight.
    • Decide on tacos or burgers for Friday night.
    • Liven up a party or a game night: everyone gets one question for the magic ball.
    • Check your gut: if the answer disappoints you, you knew what you wanted.

    Frequently asked questions

    Is the yes or no wheel really fair?

    Yes. It uses your browser's cryptographic randomness and discards values that would cause a bias. Yes and no each have a 1 in 2 chance, and that stays true with “Best of 3”.

    Is my question stored anywhere?

    No. It is only shown on your screen. The only thing remembered on your device is the mode you picked; the history disappears when you close the page.

    Why is “Best of 3” greyed out in Magic ball mode?

    The 20 magic ball replies are all different, so waiting for the same one to come up twice would make no sense. The option works with “Yes / No” and “Yes / No / Maybe”.

    Does it work on a phone?

    Yes. The page fits small screens, and you can tap the button or the answer itself to ask again. If your device is set to reduce motion, the answer appears without animation.
