Two is enough to disagree about something, which is all this needs.
Names stay in this browser. They are never put in a link, and every tool with players reads the same list.
Points for a number
An exact answer takes the exact points and the closest point is not paid on top. Nobody exact and the closest guesses share the closest point, however many of them there are.
Points for a right choice
Up to 10 points each. Points are points: nothing here is money, nothing is wagered and nothing of value is won.

Locking is the whole game
Ask a room to guess a number out loud and you will not learn what anybody thought. The second guess anchors to the first, the fourth splits the difference, and the person who goes last has heard everything and risks nothing. Written slips, locked before anybody speaks, are the oldest fix for that and the reason a sealed envelope is a thing at all.
So there is no way to edit a slip once it is locked and no way to peek at one before they all open. The device takes it, hides it and asks for the next person, and every slip appears at the same moment afterwards. It costs you the ability to fix a typo and it buys you an answer that is worth looking at.
A science lesson wants the hypothesis written down before the experiment runs, which is the part that is usually skipped and the part that makes the result mean anything. Set the answer type to a number, take the predictions, run the experiment, type in what happened. If a round needs a clock beside it, the countdown timer is the page for that, and the scoreboard is where a longer evening's points belong.
Kept in this browser under pph.predict.tally, pph.predict.scoring and pph.players, and nowhere else. Accounts, printing, storage and what the page loads are answered on the FAQ.
Questions
- Can somebody change their prediction?
- Not after they lock it. The device takes the slip, hides it and moves to the next person, and there is no way back to it. That is the whole mechanism: a prediction that can be edited once somebody else has spoken is not a prediction, it is a comment.
- How does the scoring work?
- For a number, an exact answer takes the exact points, and if nobody is exact the closest guesses share the closest point, however many are equally close. An exact answer is not paid the closest point on top. For a list, everybody who picked the right option scores. For a short answer, you mark each slip yourself, because no machine can judge one fairly.
- Is this a betting tool?
- No. Points are points. Nothing here is money, nothing is wagered, nothing of value is won, and there are no odds anywhere on the page. It is a scoring mechanic for a quiz night or a lesson, in the same way a scoreboard is.
- What is kept between questions?
- The running tally against the names in your roster, and how many points each kind of answer is worth. The question, the options and the slips themselves are gone the moment you start the next one, and none of it is ever uploaded.
