How to pick a giveaway winner fairly

Updated 12 November 2026 · By the Vast team

Close entries on time, remove anyone your rules exclude, then draw at random from what's left, with a tool you can name and a record you can show. Decide before you start whether every entry has the same chance or some actions earn extra entries, and say so in your rules. Then check the winner, contact them privately, and announce the result where people entered.

Vast is our product, so weigh that where we describe it. Our free winner picker works on any list of entries, from any platform, with no account. We checked the outside sources below on November 11, 2026.

What makes a giveaway draw fair?

Three things, settled before the giveaway starts:

Platforms add their own expectations, such as X's request that hosts ban entries from multiple accounts, and Twitch's Terms making the streamer responsible for picking winners. Our guides to X giveaways and Twitch giveaways quote the exact rules, as checked on November 11, 2026.

Should every entry have the same chance?

Either can be fair. What matters is that you choose before you start, say it in the rules, and never let money buy better odds.

A weighted draw is normal: a Steam wishlist worth 5 entries and a follow worth 1, say. The line not to cross is payment. The FTC's page on prize scams says: "It's illegal to ask you to pay or buy something to enter or to increase your odds of winning." If a paid action is in your giveaway, give a free action the same number of entries.

This isn't legal advice; check with a lawyer for your country and prize.

How do you prove the draw was fair?

How do you remove bots and duplicate entries?

Do it before the draw, and apply your rules to everyone the same way.

Don't invent new reasons to disqualify someone after you've seen who won. Use the ones your rules list.

When should you draw again?

Draw a few backup names up front and keep them in order, so you can move to the next one without a fresh draw. Our rule of thumb is one or two backups for each prize.

How should you announce the winner?

  1. Contact the winner privately first. Confirm they're eligible and how you'll deliver the prize. Never ask for an address or email in a public reply or in chat.
  2. Announce where people entered: the same post, stream, server or channel.
  3. Share the numbers. Say how many entries there were and how you drew.
  4. Protect their details. Use a first name or a masked username unless they agree to more.
  5. Say what's next, such as when the next giveaway runs.

How does Vast pick winners?

Vast is our product, so weigh this section as a vendor's description.

On Vast, winners are drawn at random when the giveaway ends, from everyone with a valid entry. Actions worth more entries improve a player's odds, so the draw is weighted by the entry values you set. The host can't win, and nobody wins twice in one giveaway. Winners show on the giveaway page by place, with masked usernames, and you see each winner's account email so you can contact them. See How winners are picked.

For your review, the entries list shows every entry from one account or one IP address, and you can mark entries invalid. If a winner doesn't qualify or doesn't claim, you can re-draw: the old winner's entries are marked invalid, and the re-draw is logged. Vast doesn't detect one person running several accounts automatically today, so that check is yours.

Vast's official rules, drafted for every giveaway, start with no purchase necessary and bar entrants from using "multiple email addresses, identities, or devices." The free plan draws one winner. As of November 11, 2026, Basic costs $15 a month or $108 a year and draws up to 30, and manual winners start on Pro at $49 a month. See our plans comparison.

FAQ

What is the fairest way to pick a giveaway winner?

Make a list with one line per valid entry, remove duplicates and anyone your rules exclude, and draw at random with a tool you can name. Record the draw and publish the method in your rules beforehand.

Can I just choose the winner myself?

Only if your rules say so. If they say random, draw at random. If you want to judge entries, such as the best fan art, write who judges and how into your rules before you start.

Is a weighted draw fair?

Yes, if your rules say how entries are earned before you start and no entry can be bought. Payment must never improve anyone's odds.

How many backup winners should I draw?

Our rule of thumb is one or two for each prize, kept in order. Move to the next one when a winner is ineligible or misses the claim deadline.
