About

Why the service exists and how it keeps draw results clear and checkable.

RaffleRoll is for teams that want a winner draw they can explain after the fact. Instead of relying on a screenshot or a one-time stream clip, it gives every draw a clear record people can revisit later.

Deterministic

The same inputs always produce the same winners, indexes, and participant hash.

Verifiable

Anyone can revisit the saved draw details and confirm the result later.

Replayable

Results include enough detail to rerun the draw without relying on hidden state.

How a draw is recorded

1. The submitted entries are saved with the draw.
2. Weighted entries are expanded into the ticket list used for the draw.
3. Public randomness is added before winners are selected.
4. The result page keeps the details needed to check the draw later.

RaffleRoll uses the open-source raffle_engine library for deterministic winner selection and replayable results.
