A prize competition website built around fair draws

Running prize competitions online comes down to four jobs. Whether you call it a raffle website, a prize competition website or a white label competition platform, these are the parts that matter.

Plenty of sites just say ‘random draw’. We publish the evidence, so a doubtful player can check a result rather than take your word for it.

Four jobs, done properly

  • Taking entries: your own branded site, built for phones
  • Picking winners fairly: automatic draws on public randomness
  • Paying out quickly: instant wins paid to the wallet in seconds
  • Proving it: a verify page on every draw and the ABOS Verified seal

Fair draws

How a provably fair draw works, in plain words

UK advertising rules expect prize winners to be picked at random, under independent supervision or by a process that can be verified. Saying ‘random draw’ proves nothing to a doubtful player. Our draws can be checked by anyone.

  1. Seal

    Before the first ticket sells, a fingerprint of the draw's secret and the instant-win prizes is published. Nothing can change without it showing.

  2. Sell

    Tickets sell. When entries close, the final entry list is fixed and fingerprinted too.

  3. Draw

    The winner comes from public randomness that does not exist until after entries close. Nobody, you included, can know it in advance.

  4. Verify

    Anyone can re-run the draw on the verify page, in their own browser, with no account, and get the same winner.

The honest bit: the sealed secret is not the winning ticket. It can't be, because the deciding randomness only arrives after entries close. What's locked early is the operator's hands, not the result.

FAQ

Competition website questions

These answers are general information, not legal advice.

How much does it cost to build a competition website in the UK?

Our build fee is £3,995 + VAT. Hosting then runs from £499 a month (Standard) up to Elite from £2,499 a month, depending on how many tickets you sell. Prizes, card fees and marketing are extra.

Do you take a cut of my ticket sales?

No. You pay one build fee and one monthly fee. The monthly steps up with your ticket volume, never with a share of your sales.

Which features come with every build?

Every standard feature listed on this page: offers, player features, provably fair draws and the full back office. You switch each one on or off from your own dashboard.

Is it legal to run a prize competition website in the UK?

Many UK businesses run prize competitions legally. A prize competition generally stays outside lottery rules when there is a genuine free entry route or a real test of skill. We build in a skill question and a free postal route, but how the rules apply depends on your set-up, so take legal advice and have a solicitor check your terms.

Do I need a Gambling Commission licence to run a raffle website?

A lottery, where people pay and winners are picked purely by chance, generally needs a licence or registration and cannot be run for private profit. A prize competition with a proper free entry route or skill element is usually treated differently. Read the Gambling Commission's guidance and take advice.

What is a free postal entry route, and is it required?

It is a way to enter without paying, usually by posting your details and answer. Postal entries should have the same chance of winning as paid ones. It is a common way to keep a competition outside lottery rules, so whether you need one depends on your set-up. Every site we build offers one alongside a skill question.

How do players know the draw is genuinely random?

The winner is worked out from public randomness published after entries close, so nobody could know it in advance. Each competition has a public verify page that re-runs the draw in the player's own browser, with no account needed, and lands on the same winner.

What does the ABOS Verified seal certify?

The integrity of the draw: that the winner, the instant-win prizes and the entry list were sealed and drawn exactly as promised, and that anyone can prove it. It certifies the maths, not whether a prize was posted on time.

Do I need to be technical?

No. We design, build, host, monitor, back up and support the site. You run your competitions from a simple back office.

Can I use my own brand and domain?

Yes. The site is designed around your name, colours and logo, on your own domain. Payments run through your own payment provider account, so the customer relationships stay yours.

Does it work on phones?

Yes. Every site is built for phones first and runs in any phone browser, from the homepage to checkout and the player's account.

Which payment providers accept competition and raffle websites?

Some card providers will not take prize competitions, so check before you sign up. Tell us which provider you have in mind and we will tell you whether we can connect it.
