よくある質問
How do tickets work?
Add tickets after a name with "x" (for example, "Alice x5"). With 5 tickets, Alice gets 5 chances out of the total ticket pool.
Can I remove winners?
Yes. Turn on "Remove winner" so each drawn entrant is taken out of the pool and can't win again.
Is the draw genuinely fair?
Yes. Winners are chosen with the Web Crypto API, so odds are exactly proportional to each entrant's ticket count with no bias.
Are my entrant names uploaded anywhere?
No. The draw happens entirely in your browser — names and tickets are never sent to a server, and it works offline.
