The official rules are the core legal document of your sweepstakes. They work as the contract between the sponsor and every participant, and courts and regulators look to them to decide what you promised. Terms you leave out or state vaguely are hard to rely on later.

This guide walks through every clause your official rules need, explains why each one matters, and highlights the drafting choices that determine whether your rules protect you or expose you.

Rules generation is only one part of the system; compare building and maintaining promotion software yourself.

Why Official Rules Matter

Official rules serve three critical functions:

  1. Legal compliance: They satisfy federal and state requirements for sweepstakes disclosures, AMOE availability, and material terms.
  2. Dispute resolution: When a participant challenges the results, the rules are the document everyone looks at.
  3. Operational clarity: The rules define exactly how the promotion works — entry methods, deadlines, winner selection, fulfillment — so your team executes consistently.

Ambiguity in rules is resolved against the sponsor

Courts generally read ambiguous contract terms against the party that drafted them, which in a sweepstakes is the sponsor. If your notification deadline is unclear, eligibility could be read two ways, or prize substitution terms are vague, expect the participant's reading to carry weight. Draft for precision, not brevity.

The Complete Clause Structure

A compliant set of official rules follows a standard structure. Here's every section, in order, with drafting guidance for each.

1. Promotion Title and Sponsor

Start with the official promotion name and the legal entity sponsoring it. The sponsor is the entity legally responsible for the promotion — this must be a legal entity, not just a brand name.

  • Required: Full legal name of the sponsoring entity
  • Required: Full mailing address (street, city, state, ZIP)
  • Optional but recommended: Promotion name or title for reference

2. No Purchase Necessary Statement

Put it at the top of the rules, typically in bold or capitals, before any other terms. For mailed sweepstakes, 39 U.S.C. §3001(k) requires both statements below, more conspicuous than other terms, along with the rules, sponsor name and address, odds, and prize details. Outside the mail, no federal statute prescribes exact wording, but the FTC Act and state laws require material terms to be clear and conspicuous.

Standard language: "NO PURCHASE OR PAYMENT OF ANY KIND IS NECESSARY TO ENTER OR WIN. A PURCHASE WILL NOT INCREASE YOUR CHANCES OF WINNING."

This statement must be prominent

Show the no purchase necessary statement at the top of the official rules, on the entry page, and in advertising. A disclosure buried in the middle of the document or in small print may not count as clear and conspicuous.

3. Eligibility

Define exactly who can enter. Be specific — vague eligibility leads to disputes.

  • Age: "Open to legal residents of the 50 United States and D.C., 18 years of age or older (19 in Alabama and Nebraska, 21 in Mississippi) at the time of entry." Alcohol-related promotions need 21+.
  • Geography: Specify included and excluded jurisdictions. If total prizes are more than $5,000 and you aren't filing in New York and Florida, exclude residents of those states explicitly; a general "void where prohibited" line doesn't do that. If you open entry to Canada, add a skill-testing question, and provide French-language materials for Quebec.
  • Exclusions: "Employees of [Sponsor], its affiliates, subsidiaries, advertising and promotion agencies, and their immediate family members (spouse, parents, siblings, children) and household members are not eligible."
  • Additional restrictions: Citizenship requirements, if applicable. Requirements for internet access or specific devices. Any other conditions.

4. Promotion Period

Specify exact start and end dates with times and timezone.

Example: "The Promotion begins at 12:00:00 AM Eastern Time (ET) on [Start Date] and ends at 11:59:59 PM ET on [End Date]."

Use 24-hour time or specify AM/PM. Always include timezone. Use seconds to avoid ambiguity about the exact moment the promotion opens and closes.

5. How to Enter

Describe every entry method in complete detail. For each method:

  • Exact steps to complete the entry
  • What information is required
  • Any limitations (one entry per person per day, etc.)
  • How the entry is received and confirmed

Purchase entry (if applicable): Describe the purchase requirement, qualifying products/retailers, and how to submit proof of purchase.

Free AMOE (required when entry is tied to a purchase or payment): Describe the free entry method in the same level of detail as the primary entry. Each free entry must have the same odds as a purchase entry, in the same drawing, for the same prizes, and free entrants must never be capped below what buyers can earn. See our AMOE guide.

Social posts (if applicable): If entrants post on social media to enter, require #contest or #sweepstakes in the post under the FTC Endorsement Guides; "#sweeps" alone is probably unclear. See our FTC sweepstakes regulations guide.

6. Entry Limits and Restrictions

  • Maximum entries per person per day and per promotion period
  • Whether multiple entries from the same email/address/IP are permitted
  • What happens if entry limits are exceeded (entries voided, disqualification)
  • Who bears the cost of entry (for mail-in: "postage required"; for online: "internet access required"; for text: "standard message rates may apply," with no premium-rate charges)

7. Prize Description

Every prize must be described with specificity:

Prize Description Requirements

  • Number of prizes available at each tier
  • Description of each prize in reasonable detail
  • Approximate Retail Value (ARV) for each prize
  • Total ARV of all prizes combined
  • Any conditions or restrictions on the prize (expiration, blackout dates, non-transferable)
  • Whether prize substitution is permitted (and under what circumstances)
  • Who bears taxes and other costs associated with the prize, including that winners of $2,000 or more in 2026 prizes will receive a Form 1099-MISC

Always include a substitution clause

Include language like: 'Sponsor reserves the right to substitute a prize of equal or greater value if the advertised prize becomes unavailable.' Without this clause, you may be obligated to deliver the exact prize described, even if it's discontinued, out of stock, or the vendor cancels.

8. Odds of Winning

State the odds or explain why they can't be stated in advance.

  • Instant win: State the odds for each prize level, for example "Odds of winning a $10 gift card are 1 in 500 per play."
  • Variable odds (drawing): "Odds of winning depend on the total number of eligible entries received during the Promotion Period."

9. Winner Selection and Notification

  • Selection method: "Winner(s) will be selected by random drawing from among all eligible entries received, conducted by [Sponsor/Administrator] on or about [Date]."
  • Notification method: "Potential winner(s) will be notified by email at the address provided at time of entry."
  • Response deadline: "Potential winner must respond within [7/14] days of notification. Failure to respond within this period will result in forfeiture of the prize, and an alternate winner will be selected."
  • Verification: "Potential winner may be required to complete and return an Affidavit of Eligibility, Liability Release, and (where legal) Publicity Release within [X] days of notification."

10. General Conditions

This section covers the legal protections for the sponsor:

  • Right to modify or cancel: Reserve the right to modify or cancel the promotion if fraud, technical failures, or force majeure makes fair operation impossible.
  • Disqualification rights: Reserve the right to disqualify entries that violate the rules, are fraudulent, or are obtained through unauthorized methods.
  • Compliance with rules: Entry constitutes agreement to abide by the rules and the sponsor's decisions, which are final.

11. Release and Limitation of Liability

Participants release the sponsor (and its agencies, partners, and platforms) from liability for:

  • Injury, loss, or damage arising from participation or prize acceptance
  • Technical failures, interrupted service, or lost entries
  • Human error in administration
  • Late, misdirected, or undeliverable entries or prize notifications

12. Privacy and Data Use

Disclose how participant data will be collected, used, stored, and shared. Link to the sponsor's full privacy policy. If the promotion involves third-party data processors, disclose them.

13. Publicity Release

If you want to use winners' names and likenesses in promotional materials, include a publicity release. Note: Tennessee bars making a prize conditional on the winner's consent to publicity in promotions tied to sales campaigns. Include the qualifier "except where prohibited by law."

14. Governing Law and Disputes

Specify which state's laws govern the rules and where disputes will be resolved.

Example: "These Official Rules and any disputes arising from this Promotion shall be governed by the laws of the State of [State], without regard to its conflicts of law provisions. Any legal action shall be brought exclusively in the courts of [State/County]."

15. Winner List

Provide a mechanism for participants to request a winners list after the promotion ends.

Example: "For a winners list, send a self-addressed stamped envelope to [Address] within 60 days of the drawing date."

Common Drafting Mistakes

  1. Vague notification timelines. "Winner will be contacted" is not specific enough. State the method, the deadline, and the consequence of non-response.
  2. Missing prize substitution clause. If the prize becomes unavailable and you have no substitution language, you may be obligated to obtain it at any cost — or face breach claims.
  3. Unclear entry limits. "One entry per person" — per day? Per week? Per promotion? Specify the period.
  4. No AMOE instructions. The AMOE must be described in the same detail as the primary entry method. A single line saying "free entries also available" is not sufficient.
  5. Forgetting platform releases. Facebook, Instagram, and YouTube require entrants to release the platform and an acknowledgment that it doesn't sponsor the promotion. A TikTok release is good practice.
  6. Copy-paste errors. Reusing rules from a previous promotion without updating dates, prizes, sponsor names, and entry methods is a common, avoidable failure.

Frequently Asked Questions

Do I need a lawyer to draft official rules?

Legal review is recommended, especially for national promotions, purchase-linked entry, or total prizes over $5,000. Smaller promotions often start from a template or platform-generated rules. Revup generates a template from your promotion settings, but it doesn't add purchase-specific terms automatically, so review and complete it before launch. If you'd rather not draft them yourself, Revup's sweepstakes administration service drafts the rules from your promotion details and revises them with your team.

Can I use a template for my official rules?

Yes, but customize every field. A template provides the structure and standard language. You must fill in the specific details: sponsor, dates, prizes, entry methods, eligibility, and jurisdiction. See our sweepstakes official rules template for a starting point.

How long should official rules be?

Long enough to cover every required element, concise enough to read. Complex promotions (instant win, purchase sweepstakes, multi-platform) need more detail than a simple single-prize drawing.

Where do the rules need to be posted?

On a publicly accessible web page linked from every entry point, with advertising telling people where to find them. The link should go directly to the full rules, not to a landing page that requires clicking through.
