About this tool
How it works.
Every draw here is provably fair. Before the drum turns we lock in a commitment hash covering your entry list and a secret seed, which you can show on stream or in your post. After the draw we reveal the seed so any viewer can recompute the winner themselves on the verify page. Most giveaway tools just ask your audience to take your word for it.
Everything is editable. Replace the list with your own, weight an entry by adding x3 after it, or switch draw modes above the entry box. Nothing is saved to a server, so your list stays in this browser.
What people use it for
- Drawing a social media giveaway
- Picking a newsletter prize winner
- Running a live product draw
Tip
Post the commitment hash in your announcement before entries close, because a receipt only proves anything if it was published first.
