Live draw and prize draw software

Provably fair draws, checked by anyone.

Every winner comes from public drand randomness that nobody can choose in advance. Players can re-check any draw in their own browser.

Trust is the product.

Entries are locked and fingerprinted, then the platform commits to a future drand round from the League of Entropy, a group of independent organisations including Cloudflare. Nobody, including you or us, can know or steer that value before it is published.

Public entry listsEvery entry in every closed competition, with a fingerprint that matches the draw.
Locked and committedEntries are frozen and a signed commitment is made before the randomness exists.
Verify this drawPlayers recompute the winner and check the drand signature in their browser.

Fair, live and on the record.

No re-rollsOnce entries are locked the draw cannot be re-rolled. A cancelled attempt stays on the public record.
Free postal entryPostal entries go into the draw with the same chance.
Made for live streamsThe round lands about 30 seconds after the lock, then you reveal the winner live.

Fair draw questions

How does a provably fair draw work?

The entries are locked and fingerprinted, the platform commits to a future drand round, and the winner is calculated from that public randomness with a published method. Anyone can repeat the calculation and get the same winner.

What is drand?

drand is a public randomness service run by the League of Entropy, a group of independent organisations. It publishes a new signed random value every few seconds, and anyone can check the signature.

Are free postal entries included in the draw?

Yes. Postal entries are added to the entry list and have the same chance of winning as paid entries.
