Remove and Clean Up Lottery Participants Before You Draw

You're about to run the draw and you notice: someone joined twice. Someone joined by mistake. Someone who already dropped out is still on the list. If you draw from a roster that's not actually correct, the result won't be correct either.

Amida-san's Organizer Plan (Pro) gives the organizer the authority to remove participants individually, so you can clean up the list and draw from an accurate roster. This article shows how to use the participant removal feature.

Why drawing from a "wrong" roster matters

Open participation makes joining frictionless, but it also lets the list drift away from what you actually want.

Common roster problems

• The same person joined twice after a retry or repeat tap
• Someone re-joined under a corrected name, leaving a duplicate
• A planned participant dropped out but is still on the list
• An unrelated person joined the event by mistake

A messy roster skews the draw

In a prize draw, a duplicate participant gets an unfair boost in winning probability. In a duty assignment, someone who already left ends up with a duty no one will actually do. The fairness of every draw starts from a correct roster.

How participant removal works

The Organizer Plan (Pro) lets the organizer remove participants individually straight from the participant list.

Clean up the roster before the draw

Remove duplicates, accidental joins, and people who dropped out, leaving only the people who should actually be in the draw. No need to ask everyone to re-confirm by hand -- the organizer can fix the roster directly.

Only the organizer can remove

Removal is an organizer-only action. Participants can't remove each other, so the feature can't be abused.

How to do it

1. Subscribe to the Organizer Plan (Pro), sign in, and create your event
2. Open the participant list once people have joined
3. From the row of the participant you want to remove, choose remove
4. Confirm and remove them
5. Once the roster looks right, start the draw

Where this helps the most

Workplace prize drawings

For a year-end party prize draw, clearing out duplicate joins before you draw ensures every employee has an equal shot.

Duty and role assignment

For fair role assignment, removing people who've dropped out prevents the draw from assigning duties to people who aren't actually around.

Large online events

For online event lotteries with many participants, accidental joins happen. Being able to remove them on the spot keeps the event moving smoothly.

Frequently asked questions

Q1: Can I remove participants on the free plan?

No. Per-participant removal by the organizer is part of the Organizer Plan (Pro).

Q2: Can I undo a removal?

If the removed person rejoins, they'll be back on the list. So even an accidental removal is recoverable -- just ask them to rejoin.

Q3: Can I remove participants after the draw has started?

Participant removal is designed for cleaning up the roster before the draw. If you've already finalized the result and need to redo it, use re-draw instead.

Q4: Are removed participants notified?

When a removed participant reopens the event, the screen shows that they are no longer a participant.

Q5: How much does it cost?

The Organizer Plan (Pro) is $39 / month or $390 / year (annual saves about 2 months). Participant removal is bundled with re-draws, participation restrictions, and more.
