Fairness & Draw Verification
This page explains how Raffio draws winners — and, crucially, how anyone can independently check that a draw was fair, without having to trust us. Draws are seeded by RANDOM.ORG, an independent third-party randomness service, using a single-use ticket that we commit to before the winner is known.
Draw Process
When a competition closes, its winner is chosen by a random number drawn from RANDOM.ORG. The draw runs automatically after the closing date and time, over all valid entries received before closure. It works in two committed steps:
- Before the draw:Raffio allocates a single-use RANDOM.ORG ticket and publishes its ID on that competition's own verification page. Because the ticket is committed before the result exists — and can only ever be used once — Raffio cannot keep requesting numbers until it likes the outcome. RANDOM.ORG's own public record of that ticket would expose any such attempt.
- At the draw: the committed ticket produces a signed random number. That number, combined with the fixed list of entries, selects the winner through a published, deterministic formula that anyone can re-run.
The result is that:
- All ticket holders have an equal chance of winning
- The randomness comes from an independent source Raffio cannot control or re-roll
- The winner can be reproduced and verified by anyone, against RANDOM.ORG
- Draws occur only after entry closure, not before
Every competition has its own permanent verification page showing this evidence — live both before the draw (the committed ticket) and after (the full signed result). You can see all past draws, each linking to its evidence, on the Results page.
Platform Control
Raffio operates draw systems independently from hosts. Hosts cannot:
- Select winners or influence the outcome
- Control draw timing or access draw mechanisms
- View or modify the selection process
All draw processes are platform-controlled and transparent. These processes are designed so that outcomes are determined fairly and are not influenced by hosts or any third party.
Verification and Records
Each competition's verification page publishes everything needed to check the draw independently. There are three separate things a verifier can confirm:
- Provider authenticity— the signed random number can be pasted into RANDOM.ORG's own signature-verification form, which confirms it with RANDOM.ORG's key, not ours. The committed single-use ticket can also be looked up directly at RANDOM.ORG.
- Pool binding — the signed data includes a fingerprint (hash) of the exact entry pool, proving the list of entries was fixed before the random number existed.
- Deterministic selection — the winner follows mechanically from the random seed and the entry pool via a published formula. The verification page includes a short snippet you can run yourself to reproduce the winning ticket.
For every completed draw Raffio also records the competition ID, the exact draw timestamp, the number of valid entries, the winning ticket, and the full signed provider evidence. A machine-readable copy of the proof can be downloaded from each verification page. These records are retained securely and can be reviewed in the event of a dispute or audit.
Each competition's verification page always shows the exact randomness source used for that specific draw. In rare cases where an external draw could not be completed, a draw may fall back to Raffio's own generator — that page will say so plainly and is never presented as third-party-verified when it isn't.
Valid Entries
Only entries that meet the following criteria are included in draws:
- The participant successfully completed ticket purchase
- The participant correctly answered the qualifying question
- The entry was received before the listing closing date and time
- The entry is associated with a valid account
Invalid entries, such as those with incorrect qualifying question answers, are excluded from the draw. This process is designed so that only legitimate entries participate in the selection process.
