Giveaway rules generator: what it should write and what you still add

Updated 10 November 2026 · By the Vast team

A giveaway rules generator turns a few details, such as your name, the prizes, the dates and the country, into a set of official rules. A good one writes the clauses that every giveaway needs, such as "no purchase necessary", who can enter, the odds, how winners are picked and a platform disclaimer. It can't know your local law or your prize, so it should leave clear gaps for you to fill. Treat any generator, ours included, as a first draft.

Vast is our product, so weigh that. We read Vast's rules from the code that writes them on November 10, 2026, and checked the platform and legal pages named below the same day. Where a live page blocked us, we read an archived copy and say so. This isn't legal advice; check with a lawyer for your country and prize.

What a generator has to produce

Our giveaway rules template guide has the full checklist and a fill-in template. This table is the short version, with the first column showing what the rules need to say.

ClauseWhat it must sayWhy it matters
No purchase necessaryEntering and winning cost nothing, and paying doesn't improve oddsCharging to enter can turn a giveaway into an illegal lottery in the US
SponsorYour legal name and a way to contact youEntrants and regulators need to know who runs it
EligibilityAge, places, who is excluded, "void where prohibited"Prize laws vary by country and state
Entry periodStart and end, with a time zoneSettles late entries
How to enterEach method, limits, a ban on duplicate accounts and botsPlatforms ask for it too
PrizesWhat, how many, approximate valueNeeded by some laws and ad rules
OddsWhat they depend onRequired in some places
Winner selectionHow, by whom, whenFairness you can show
Notification and claimHow you contact winners and how long they haveHandles winners who vanish
Platform disclaimerThe platform doesn't sponsor or run itRequired by Meta and Twitch
Governing lawWhich country's law appliesSettles disputes

Where the law is strict, the rules must reflect it. The FTC's page on fake prizes says: "It's illegal to ask you to pay or buy something to enter or to increase your odds of winning." That is why the "no purchase necessary" line comes first.

How Vast's rules work

Vast writes official rules for every giveaway in the builder's Description and rules step. Players open them from Official rules in the entry panel, or from Show rules at the bottom of the giveaway page. If a giveaway has no rules of its own, players see Vast's standard terms.

You fill in a few fields and the rest comes from your giveaway:

You provideVast fills in from your giveaway
Sponsor name and addressGiveaway title and link
How winners are selectedStart and end date, in your time zone
Days to contact winnersPrize names, number of winners and each prize's value, if you set one
Days winners have to claimMinimum age, as set in the builder
Governing countryThe country the giveaway is limited to, if you chose one
Privacy policy link (optional)
Additional terms (optional)

You can edit the details or write your own rules instead.

What the generated rules cover

What you still add

Vast fills in the age, the place and the prize values you set in the builder. These are the parts it leaves for you to check or add, in Additional terms or your own rules.

Platform rules to cover

PlatformWhat its rule saysCheck in your rules
Meta (Facebook, Instagram)Promotions need legal compliance, a release of Meta and an acknowledgment it doesn't sponsor them. You can't require people to share, repost or tag others.Check the release wording and add your own. Don't reward sharing or tagging.
XInclude a rule that multiple accounts make an entrant ineligible. Don't reward duplicate posts. You're responsible for the law.The generated rules ban multiple identities.
TwitchYou're the promoter. Display "This is a promotion by [Your Name]. Twitch does not sponsor or endorse this promotion and is not responsible for it."Add the exact line.
YouTubeFree to enter, rules that link to YouTube's Community Guidelines, no suggestion that YouTube sponsors it, and no taking all rights.Check each.

Sources for each row are listed below. Our guide to running giveaways on X, Discord, Twitch and Kick goes through them in more detail.

State and country notes

A generator can't tell you whether your giveaway needs a filing. Some places add rules once you cross a threshold or accept entries from a country.

If you're unsure whether you're over a threshold, limit entrants to a country you've checked. The Pro plan can limit a giveaway to one country by where the entrant's connection comes from, which a VPN can change.

How Vast compares

Gleam also writes terms for you, from a template, and can add a free-entry alternative to paid actions, shown only in countries that need one (details in our Gleam vs Vast comparison). That is a real strength where you give entries for a purchase or a paid subscription. Vast's rules assume entry is free and give you no paid-entry handling, so don't give extra entries for paying.

Pick winners in a way you can explain

Your rules must say how winners are picked, and then you must do it that way. Vast draws winners at random from everyone who entered, and actions worth more entries improve a player's odds. If you run your own draw, our free giveaway winner picker picks at random in your browser, and nothing is uploaded. Screenshot the draw with the entry count and the time.

A short checklist before you publish

  1. Read the generated rules from start to end, as a player would.
  2. Check that the minimum age, place and prize values match what you meant, then add any extra exclusions and platform lines.
  3. Check your prize total against the New York and Florida thresholds.
  4. Confirm that nothing in your entry list requires payment.
  5. Put the rules link next to the entry button wherever you share the giveaway.
  6. Ask a lawyer if the prize is valuable, the entrants are in several countries or you're unsure.

FAQ

Is a rules generator legal advice? No. It writes standard clauses from what you enter. It doesn't know your laws or prize.

Do I have to use Vast's generated rules? No. You can edit the details or use your own.

Does Vast's generator add a skill-testing question? No. Add one if Canadians can enter.

Do the rules include the minimum age I set? Yes. The rules state it, and also name the country and any prize values you set. Add anything beyond that, such as extra exclusions, yourself.

Can I give extra entries for buying something? Don't. A giveaway that charges to enter can become an illegal lottery in the US. Ask a lawyer before adding any paid option.
