Call It

The guessing question for your event

Office party
How many cars fit inside an A380?

You print a poster with a QR code and put it up. It runs on its own from there — no projector, no host, no sign-up. Guests guess as they walk past; you enter the right number at the end.

How it works

  1. Ask the question

    You set the question and when guessing is open. Anything with a number for an answer works.

  2. Print the poster

    You get a QR code and a ready-made poster to print. Put it up — from there it runs without you, all evening or all weekend.

  3. Draw the winners

    Nobody sees anyone else's guess. You enter the right number at the end and the ranking is there straight away.

Fair, without a login

One guess per browser, one per name. Anyone who wants to can get past that with a private window and a new name. For a party that is enough.

Light on data

A name and a number, nothing else. Guests need no account. Everything is deleted 30 days after the game.
