Drawing winners (raffle / prize draw)

A raffle is a question type where participants don't vote, they sign up. They enter their name and go into the hat. Later — typically at the end of the day — you set the number of winners and draw them.

Setting it up

  1. In the host panel click + New question and pick the Raffle / prize draw type.
  2. Write what's at stake in the question text — e.g. "Prize draw for the main prize".
  3. Optionally enable:
    • Also ask for a contact — besides the name the participant fills in an e-mail or phone so you can reach the winner. You can set your own field label.
    • Show entrants' names to the audience — the audience sees the list of entries. Off by default, because these are personal data.
  4. Activate the question like any other (Activate button) so it appears on people's phones.

How people enter

A participant opens /q/{code} (or scans the QR), types their name and taps Enter the draw. Done — they're in.

Until the first draw happens they can fix their entry (a typo in the name). After the first draw the hat locks, so nobody can rewrite a name you have just read out from the screen.

Drawing

On the question in the host panel:

  1. Set the number of winners.
  2. Optionally fill in a draw name — e.g. "Main prize" or "Vouchers". It shows up with the result and helps when you draw several times.
  3. Click Draw.

Winners appear immediately:

  • on the projector (/tools/qlive/{id}/present) in large type,
  • on the audience's phones — whoever won sees "🎉 You won!",
  • on the shared results page /qv/{code},
  • in the host panel, including contacts if you collected them.

The owner, a co-host and the presenter can all run a draw — it is an on-stage action, just like switching the active question.

Several prizes in a row

Draw as many times as you like — first prize, second prize, consolation. By default previous winners are not drawn again; if you want one person to be able to win several prizes, untick Don't draw people who already won.

If nobody is left in the hat, the system says so instead of drawing nothing.

When something goes wrong

A draw started by mistake (wrong number of winners, premature click) can be deleted — the bin icon next to that draw. The winners go back into the hat and you can draw again.

Fairness

The server draws, not the browser, using a cryptographic random generator with bias-free distribution — every entry has the same chance. Nobody can win twice in a single draw. The result is stored as a snapshot including names, so it can be verified afterwards.

Export and personal data

The XLSX export (Export button in the panel) has two extra sheets:

  • Loterie — all entries including contact and a note on what they won,
  • Výherci — an overview of draws, positions and contacts.

Names and contacts are personal data. Collect only what you really need, tell people what it will be used for, and delete the records once the prizes are handed over (deleting the event deletes the entries too).
