How do I pick a random contest winner?

Paste your validated entrants — one per line — choose how many winners you need, and hit Pick Winner. The tool draws randomly and shows the reveal. Each draw publishes a verification hash so the result can be independently checked.

Can I give bonus entries for shares or referrals?

Yes, with *N weighting. Add '*5' after an entrant to give them five times the odds — ideal for rewarding referrals, shares, or higher entry tiers. The weights are folded into the verification hash, so a weighted contest draw is still provably fair.

How do I prove the contest draw was fair to a sponsor?

Each draw reveals a 256-bit random seed, hashes your exact entrant list with SHA-256, and publishes a verification hash plus a selection log. A sponsor re-runs the same algorithm with the seed and list and confirms the identical winners — no trust required.

Can I draw winners for several prize tiers at once?

Yes. Set a custom winner count; winners are drawn without replacement and revealed from the lowest tier up to the grand prize, so one run produces your whole ranked winner list.

Is entrant data (like emails) kept private?

Yes. The picker is fully client-side — there's no account and no database, so emails and usernames are never uploaded. Close the tab and the list is gone.

What is a contest winner picker?

A contest winner picker is a tool that randomly selects winners from a list of contest entrants. You paste the validated entries — usernames, emails, or IDs — and the tool draws one or more winners at random, optionally weighting entries that earned bonus chances.

Beyond drawing a name, this tool gives you a defensible result: a verification hash and selection log you can hand to a sponsor or compliance reviewer, plus an animated reveal for the announcement.

Running a fair, compliant contest draw

Contests with prizes often carry rules — official terms, eligibility checks, and sometimes regional sweepstakes law. The mechanical part you control is the draw: validate eligibility first, finalise the entrant list, then pick with a verifiable random source.

Paste your finalised, eligibility-checked list here and draw. Keep the seed and verification hash with your contest records; because any change to the entrants changes the entries hash, the proof is bound to the exact list you drew from — exactly what a sponsor or auditor wants to see.

Weighting bonus actions correctly

Many contests award extra entries for actions like referring a friend, sharing a post, or buying a higher tier. Pasting a name multiple times works but is hard to audit; weighting is cleaner. Give each entrant one line with a weight equal to their total entries — 'sam*4' for four entries.

The picker uses Efraimidis–Spirakis weighted sampling without replacement, so multi-winner draws bias each pick by weight while guaranteeing distinct winners across your prize tiers.

How to use contest winner picker

Finalise your entrants. Validate eligibility, then copy your entrant names, emails, or IDs.
Paste and weight. Paste one per line. Add *N to reward referrals, shares, or higher tiers.
Set winner count. Choose one winner or a custom number for tiered prizes and backups.
Draw and document. Pick the winners, then save the seed and verification hash with your contest records.
