    What is Door Prize Winner Picker?

    Door Prize Winner Picker is a free browser-based door-prize draw tool for selecting winners from an approved guest, badge, or ticket list. Edit the sample entries, confirm the eligible list, choose the mode that matches the activity, and spin for a visible random result. Publish eligibility and redraw rules first, remove ineligible duplicates, verify the selected person, and record each accepted winner before continuing.

    Decide who qualifies before the draw

    Specify whether the person must be present, checked in by a certain time, registered for a session, or holding an issued ticket. Remove cancellations, staff entries, test registrations, and anyone excluded by the published event rules.

    Closeentry list
    Checkattendance rule
    Spinone badge ID
    Verifybefore handover

    A practical event workflow

    Badge-number method

    Use a unique badge ID on the public display and keep the attendee lookup list with authorized event staff.

    Presence-check method

    Announce how long the selected person has to respond and how a replacement will be drawn.

    For multiple prizes, decide whether one attendee can win more than once. Enable removal for one-prize-per-person events, or use the Multiple Winners wheel when you need several unique results together.

    Door Prize Winner Picker FAQs

    Must the winner be present?

    Only when that condition appears in the announced event rules.

    Can badge numbers protect privacy?

    They can reduce the personal information shown publicly when the organizer keeps the lookup record secure.

    How do I draw a replacement?

    Record the first result, remove it if required, and spin again under the published replacement rule.
