Random winner picker
Paste the names, pick your winners and share a results page anyone can check. Fair by design: the randomness doesn't exist until your list is locked in.
Your winner lands here
Doo draws with public randomness that doesn't exist until after your list is locked in. Anyone can check the result.
Questions people ask
- How does the random winner picker work?
- Paste your entrants, one per line, or upload a CSV. Choose how many winners you need, then pick. Perkadoo locks in your list, waits a few seconds for the next public drand randomness round, and uses it to shuffle the list and pick your winners.
- Can people check that the giveaway was fair?
- Yes. Every draw gets a public results page with the list's fingerprint, the drand round and the exact recipe. The round is published after your list is locked in, so nobody, including us, can know or steer the result. Anyone can recompute the winners.
- Can I pick winners for an Instagram or TikTok giveaway?
- Yes. Export the comments or entries to a CSV, or paste the usernames. Turn on “One entry per name” if each person should only count once.
- Is it free?
- Yes, with no sign-up. Free results pages keep the names for 30 days. Sign up free to keep them for good and add your brand.
