Competition Terms

> DRAFT — REQUIRES UK LEGAL REVIEW BEFORE LIVE-MONEY LAUNCH

1. Relationship to the Terms of Use

These Competition Terms apply to every Competition on the Platform in addition to, and read together with, our Terms of Use. Where a specific Competition page states a rule that conflicts with this document (for example a different closing date), the Competition page controls, unless it concerns a critical term as described in section 2.

2. Critical Terms Are Locked Once a Competition Opens

The entry price, maximum number of paid Entries, per-person entry cap, prize (asset), closing time, opening time, whether a Draw is guaranteed, and the Free Entry Route instructions are all fixed the moment a Competition opens and cannot be changed afterwards except through a documented, audited exceptional process reserved for extraordinary circumstances (for example extending a closing date), never to a Competition's disadvantage of Entrants already holding tickets.

3. Entry Methods

You may obtain Entries by paying the listed entry price at checkout, or without payment through the Free Entry Route described in our Free Entry Route document. Both methods produce identically weighted, sequentially numbered tickets in the same pool.

4. Entry Limits

Each Competition states a maximum number of paid Entries and, where applicable, a per-person cap combining paid and free Entries. Free Entries are additive to the maximum paid Entries figure — accepting postal entries never reduces the number of paid tickets available, and vice versa. This is enforced by the Platform's inventory logic, not just displayed as a number: a paid Entry can never be sold once the maximum is reached, and the per-person cap is checked against your confirmed tickets plus anything currently in your basket before a new order is accepted.

5. Sold-Out Competitions and the Free Entry Route

Once the maximum number of paid Entries has sold, a Competition is marked sold out and no further paid Entries can be bought. The Free Entry Route, however, remains open: valid postal entries are still accepted and still receive a ticket, right up until the entry pool is frozen for the Draw. This reflects the same principle as section 4 — the free route is never squeezed out by paid demand.

6. The Draw Pool

When a Competition closes, all confirmed tickets — paid and free — are combined, in ticket number order, into a single, permanent snapshot. The snapshot's cryptographic hash and its full contents (ticket numbers and opaque ticket identifiers only, no personal data) are published, alongside the total counts of paid and free tickets it contains. Nothing can be added to or removed from the pool after this point; the snapshot cannot be edited by anyone, including PrizeProof.

7. Guaranteed Draw

Where a Competition page states the Draw is guaranteed, a winner will be selected from the entries received regardless of how many paid Entries actually sold, unless the Competition is cancelled outright under section 11 before it closes. A guaranteed Draw is not a promise that a Competition will sell out — only that, once entries close normally, a Draw will take place.

8. Draw Mechanism and Verification

The winning ticket is selected using a commit–reveal protocol combined with public randomness from the drand randomness beacon, using unbiased rejection sampling. In outline: a secret is committed before the Competition opens; the entry pool is frozen and hashed at close; a beacon round that did not exist at close time supplies the entropy; and the winning ticket is derived from all of this by a fixed, published formula. The full mechanism, including the exact formulas used, is published at docs/draw-protocol.md and on each Competition's verification page once drawn. Anyone — not only PrizeProof — can independently recompute the commitment, the pool hash, the beacon value and the winning ticket from the published material alone.

9. Announcing and Contacting the Winner

We will contact the winning Entrant using their account details. A winner's own account always shows their result, whether or not they consent to any public announcement. Public announcement (including a display name) only happens with the winner's consent; where consent is not given, the winner still appears on our public winners page without any identifying detail.

10. Prize Delivery

Delivery or collection arrangements are confirmed with the winner directly and may require identity verification before a prize is released, consistent with our Eligibility Rules. Delivery timescales vary by prize type and are confirmed with the winner at that stage; large or high-value prizes (for example a vehicle) may require additional handover steps such as insurance or registration paperwork.

11. If a Competition Does Not Proceed

If a Competition is cancelled before a Draw takes place, all paid Entrants for that Competition are refunded in full and any Free Entry Route entries already logged are simply not carried forward. If a Draw cannot be completed as guaranteed for reasons genuinely outside our control, we will publish the reason and the resolution, which may include a refund or a rescheduled Draw over the same, unmodified entry pool.

12. One Winner Per Competition

Each Competition produces exactly one winning ticket per Draw. Holding multiple Entries in the same Competition increases your chances proportionally but does not change this — only one ticket number is ever selected as the winner of a given Draw.

13. Promoter Details

The promoter of Competitions on the Platform is PrizeProof. Registered company details: [to be completed before launch].
