CAP Code rule 8.24

CAP Code 8.24 and verifiably random prize draw results

CAP Code rule 8.24 is the key UK advertising rule for prize draw winner selection.

ScirDom supports the computer-process route by recording the locked participant list, tested randomness, published algorithm, signed certificate, and evidence pack.

SCIRDOM EVIDENCE LAYER

  • Tested randomness before the draw
  • Participant register locked before execution
  • Published winner-selection algorithm
  • Signed certificate and evidence pack
  • Verification material for independent checking

ANSWER

What is CAP Code rule 8.24?

Rule 8.24 says promoters of prize draws must ensure prizes are awarded by chance and, unless winners are selected by a computer process that produces verifiably random results, by an independent person or under independent supervision.

ANSWER

How does ScirDom support the verifiably random computer-process route?

ScirDom is designed for the computer-process route. It locks the participant register, uses pre-tested entropy, applies a published selection method, records the entropy portion and algorithm version, and creates a certificate and evidence pack for the completed draw.

ANSWER

Does ScirDom become the independent person?

No. ScirDom provides technical infrastructure and evidence materials. It does not act as an independent judge, independent observer, regulator, or legal adviser.

Why evidence matters

The phrase verifiably random is practical. It means the promoter should be able to show enough evidence for the draw process to be checked, not merely make a general statement that a random process was used.

ScirDom's evidence model is built around that need: fixed entries, a fixed method, pre-existing randomness, and signed records after execution.

ScirDom evidence mapped to rule 8.24

  • Locked participant register: shows the final list used for selection.
  • Entropy reference: shows the randomness material assigned to the draw.
  • Algorithm publication: shows the fixed method used to convert randomness into a winner sequence.
  • Certificate and manifest: record the result and supporting verification values.

Need evidence for a prize draw?

ScirDom helps promoters evidence fair winner selection through tested randomness, locked entries, a published algorithm, signed certificates, and complete evidence packs.
