Every draw we've ever run, in one place — each one independently verifiable by you, not just us. Every prize is awarded in accordance with the laws of chance: the winning number comes from public randomness created after entries close, mixed with a secret we committed to before a single ticket sold. Free and paid entries have an equal chance of winning. Don't trust us — check.
Most competition sites just tell you "don't worry, it's random" — and you have to take their word for it. We didn't think that was good enough. So we built Bullpen so you never have to trust us. Here's the whole idea in one picture:
Before a single ticket goes on sale, we lock in a random secret and publish a fingerprint of it. Think of a sealed envelope on the table — you can see it's sealed and can't be swapped. But the key thing: this secret is not the winning number — it's just one ingredient, and on its own it reveals nothing.
When entries close, the winning number is decided using a public random value from an independent worldwide service — run by universities and organisations around the globe — that simply doesn't exist until after your comp closes. Nobody, us included, can know it early or nudge it.
We combine the sealed secret with that public number, then open the envelope. Anyone can redo the sum and land on the exact same winning ticket, right in their browser. If we'd fiddled anything, the envelope wouldn't match — and everyone would see.
This trips people up, so let's be dead clear. When we seal the envelope before sales, even we don't know who will win — it's impossible for anyone to know yet. The secret is just a random scrambler. The winning ticket doesn't exist until that secret is combined with the public random number that only appears after your competition has closed. We commit early purely so we can't change our ingredient once we see who entered — not because the winner is decided early. It isn't, and it can't be.
You don't need to understand a scrap of the maths to be safe. But if you're curious, hit Verify on any draw below and walk through every step yourself — the numbers are all there.
