We design, build, host and certify your prize-competition site on a provably-fair engine. Every winner is drawn with public randomness and can be re-checked by anyone — so your players don't have to trust you, they can prove you. Live in weeks, carrying the ABOS Verified seal.
Players have watched too many draws they couldn't see, on sites that could quietly move a ticket, edit a prize or pick a friend. One rumour burns a brand overnight — and honest operators have had no way to prove they're straight. We fix that at the engineering level.
The clever part is the order of events — and it's simple enough to say on a poster.
Before ticket one, we publish a cryptographic fingerprint of the sealed prize map. It can't be changed later without everyone seeing.
Tickets sell. The full, timestamped entry list is on show — nothing can be quietly added or removed.
At draw time the winner is derived from drand — a global public randomness beacon that literally does not exist until after entries close.
We reveal the seal. Any player re-computes the exact same winner in their browser — no account, no trust required.
The honest bit: the sealed secret is not the winning ticket — it can't be, because the deciding randomness isn't born until after entries close. All that's locked early are your handcuffs. That's the sentence that kills the “you knew the winner all along” objection before it starts.
Before a single ticket goes on sale, the draw's secret is locked in a glass safe and the safe's fingerprint is published for anyone to screenshot. From that second, nothing inside can change without the fingerprint breaking — in public.
The winner isn't picked by us, the site owner, or a button somebody presses. It comes from a public coin-toss service used worldwide — and the toss the draw uses doesn't exist yet while tickets are selling. Nobody can peek at a number that hasn't been created.
After the draw, the safe is opened in public. Your own phone can re-run the entire draw and land on the same winner. If even one ticket had been moved, the numbers wouldn't line up — and everyone would see it.
The draw date can't quietly move. The prize map can't be shuffled. A mate can't be picked. The operator couldn't fix the draw even if they wanted to — and that sentence is worth more than any "trust us" badge in the industry.
At publish, the engine generates a secret seed and publishes its SHA-256 commitment; instant-win maps are committed as a salted hash of the canonical map. Any post-publish change to the draw or the prize map breaks the published digests.
The winning entry is a deterministic function of the sealed seed, the final entry list's hash, and a pre-nominated future round of the drand beacon (League of Entropy) — BLS threshold-signed, publicly verifiable, and generated only after entries close. Unpredictable to us, the operator, and everyone else.
Winner derivation is uniform over the sorted entry list with rejection sampling — no modulo bias, no re-rolls, no operator discretion anywhere in the path. Free postal entries sit in the same list with identical odds.
The public verify page recomputes everything in the visitor's browser via WebCrypto: commitment vs revealed seed, instant-map re-derivation, entry-list hash, and the beacon signature fetched directly from independent drand endpoints. Our servers are not part of the trust chain.
Not a plugin bolted onto a shop. A purpose-built platform — the same one running our own flagship — skinned to your brand and handed to you fully staffed.
Commit-reveal plus public randomness on every draw. Auto-draws or a live on-stage reveal — both verifiable to the ticket.
Sealed instant-win maps with 14 branded reveal games — safes, scratch cards, advent doors and more. All theatre, zero reel-gambling mechanics.
One-screen comp builder, wins audit, customer 360, live reporting and P&L, prize fulfilment tracker and printable shipping labels.
Hosted card checkout, site-credit and cash wallets, instant-win payouts and player cash withdrawals — PCI handled by the gateway, not you.
Audience sync, abandoned-basket recovery, branded emails and one-click broadcasts to opted-in players — all GDPR-clean.
Players install your site like a native app straight from the browser — home-screen icon, offline shell and push notifications.
An OBS-ready draw show — slot-spin reveal, on-screen verification ticks and a scan-to-check QR for viewers' phones.
Skill question and free postal route, 18+ gating, responsible-play limits and self-exclusion, GDPR export and erasure — the legal scaffolding, ready.
No-oversell ticket allocation, stress-tested against stampedes, hosted with SSL and rolling backups. Zero duplicate tickets, ever.
No modules to buy, no feature paywall, no “that’s an add-on”. One package — this is everything that runs on your site from day one, the same system our own flagship runs on. Your Site-features dashboard decides what’s switched on.
The platform gets you online. ABOS Verified is what makes players choose you — a trust network no competitor can copy overnight.
The ABOS Verified seal only stays on your site while every draw checks out. It becomes the badge punters learn to trust — the way a padlock means “safe”.
Every hosted site sits on one public Fairness Register. We independently re-derive each draw. Tamper with anything and a tick flips red — permanently, for the whole world to see.
Verified competitions rank top on CompHunter, the aggregator where players discover comps — distribution and a trust advantage your non-verified rivals simply can't buy.
We map your look, categories, prize model and payment setup on a single call.
Your site, your colours and logo, on our platform — the whole back office and player experience, ready in weeks.
You join ABOS Verified. Every draw starts auto-proving from day one, and the seal goes live on your site.
We host, back up, monitor and support — you appear on CompHunter and get on with running competitions.
You could stitch together a shop, a plugin, a host and a designer — and still not be able to prove a single draw. Here's what you get instead.
Every draw is publicly verifiable and carries the seal. No rival can offer that without joining our register — which is exactly the advantage you're buying.
Stress-tested against sell-out stampedes with zero oversold and zero duplicate tickets, on infrastructure built for the final-hour rush — not a demo that's never seen real load.
One build fee, one flat monthly. We never take a cut of your draws — every penny of the upside is yours to keep and grow.
When a competition sells out in minutes, our no-oversell engine holds. Stress-tested against stampedes: zero duplicate tickets, zero oversell.
Skill question, free entry, 18+, responsible play and GDPR tools ship as standard — the legal scaffolding ready, not bolted on after a scare.
We design, build, host, certify and get you onto CompHunter. One team, one bill — no agency-plus-plugins-plus-host juggling act.
The government's Code of Conduct for prize draws and competitions expects signatories to be fully compliant by 20 May 2026 — player protections, transparency and accountability. Most operators will scramble to retrofit it. Ours inherit the hard parts on day one. Here's the honest split of who does what.
Why this matters: the Code's implementation deadline is 20 May 2026. Operators building on spreadsheets and shop plugins have to retrofit every one of these measures by hand. Operators on this platform switch them on.
We build your site totally bespoke — your name, your colours, your world, your character. No templates, nothing that looks like anyone else. Underneath, every one runs the identical proven engine: provably-fair draws, instant wins, leaderboards, daily free entries, live draw nights. The concepts below are five we imagined from scratch — yours would be its own. Click any to explore the full site.
One package — every build gets the full platform, every feature and the seal. No revenue share: you pay to build it and keep it hosted, certified and supported. The upside is entirely yours.
Run correctly, prize competitions are legal in the UK when they turn on genuine skill and offer a free entry route — which is different from a lottery. We build both in from day one: a skill question and a free postal route, plus 18+ gating and responsible-play tools. We set up the scaffolding; you'll still want your own solicitor to sign off your terms — we're engineers, not your legal counsel.
The integrity of the draw — that the winner, the instant-win map and the entry list were sealed and drawn exactly as promised, provable by anyone. It is deliberately honest about scope: it certifies the maths, not whether a prize was posted on time. Prize fulfilment is a separate reputation layer, and we never pretend otherwise.
Yes — with no account and no trust in us. Each competition has a public verify page that fetches the same public randomness and re-derives the exact same winner in the player's own browser. If our number and their number match, the draw was straight. If they didn't, it would be obvious to everyone.
No. We design, build, host, monitor, back up and support the whole thing. You run competitions from a simple back office; we keep the lights on and the seal valid.
Completely. The site is skinned to your colours, logo and voice on your own domain, and we can migrate you across from an existing site. Payments run through your own gateway account, and email and SMS connect to your own providers — so you own the relationships, not us.
Yes — every site ships as an installable web app: players add it to their home screen with your icon and get push notifications, with no app store needed and nothing to approve. On the White-label tier we also build native iOS and Android apps — but we'll be straight with you: getting a prize-competition app approved, on Apple's store especially, is genuinely hard right now, and the stores control that, not us. We build and submit it; most operators launch on the web app from day one and add native once approval lands.
Book a 20-minute demo. We'll show you a live provably-fair draw, the register, and exactly what your site would look like carrying the seal.
