How it works
- Type your question if it helps to see it written down — it stays on your device.
- Press "Shake the ball", or just hit Enter in the question box.
- The answer appears in the window and joins the history, tagged positive, non-committal, or negative.
- Watch the tally to see the split even out as you keep asking.
The twenty answers, and the odds behind them
This keeps the answer set of the original 1950s toy, which is deliberately optimistic:
10 positive → 10/20 = 50%
5 non-committal → 5/20 = 25%
5 negative → 5/20 = 25%
So the feeling that the ball is on your side is real, and it comes from the answer list rather than from the shuffle. Each individual reply still has exactly a 1-in-20 chance of coming up.
Keeping those odds honest takes a little care. A random byte gives 256 possibilities, and 256 divided by 20 leaves a remainder of 16 — so simply taking the remainder would make the first sixteen answers slightly more common than the last four. The code discards any byte of 240 or above and draws again, which makes every answer exactly equally likely at the cost of a redraw about 6% of the time.
FAQ
Is my question sent anywhere?
No. The question box is there to help you focus your thinking — the text stays in the page, is never uploaded, and is not even used to pick the answer. Reloading clears it along with the history.
Are all twenty answers equally likely?
Yes. Each shake draws from your browser's cryptographic random number generator using rejection sampling, so every one of the twenty replies has exactly a 1-in-20 chance. Nothing weights the outcome towards a cheerful answer.
Why do I get positive answers so often?
Because the original toy is built that way, and this keeps its exact set: ten of the twenty answers are positive, five are non-committal, and five are negative. So a yes-ish reply genuinely turns up half the time — that is the toy, not a bias in the code.
Does my question influence the answer?
Not at all, and no tool could — that is the joke. The value is in being forced to phrase a decision as a clear question, and in noticing your own reaction to the answer you get.
What is the tally for?
It counts how many positive, non-committal, and negative replies you have had this session. Over enough shakes it should drift towards the 50/25/25 split of the answer set — a small demonstration that the draw really is even.
Should I use this for real decisions?
For deciding which café to try, absolutely. For anything that matters, treat it as a prompt rather than an answer — a coin toss with twenty faces is still a coin toss.
