FAQ
How do I run a giveaway by numbers?
Number the participants, set the range from 1 to the number of participants and the number of winners. "No repeats" prevents picking the same person twice.
Can I pick from a list of names?
Yes, on the "Picker" tab paste participants one per line and set the number of winners.
Is it fair?
Numbers come from the browser cryptographic generator, so the result cannot be predicted or rigged. Record your screen while drawing to show your audience.
