The lucky number test

Pick your lucky number, run up to 10,000 simulated draws right here in your browser, and watch what a fair lottery machine really does to it.

Runs entirely on your device using unbiased random numbers from your browser's cryptographic entropy source. Nothing is sent anywhere.

What you're looking at

Each bar counts how often one number came out across every simulated draw. The dashed line is the expected count if the draw is fair — total numbers drawn, divided equally. At 100 draws the chart looks jagged and "hot" numbers leap out at you. At 10,000 the bars flatten towards the line. Nothing about the numbers changed between those two charts; the only thing that changed is how much evidence you collected.

Why the streaks fool everyone

Human brains are pattern detectors, and small samples are full of fake patterns. In 100 draws of EuroMillions numbers, the luckiest number typically appears 40–80% more often than the unluckiest — genuinely, visibly "hot". Frequency-tracking websites are built on exactly this observation. The problem: run the same test again and a different number is hot, because the streaks are a property of small samples, not of the balls. Statisticians call the belief that a recent streak predicts the future the hot-hand fallacy, and its mirror image — "13 is overdue" — the gambler's fallacy. A fair draw has no memory, so both are wrong for the same reason.

What this simulator uses — and what it doesn't

Every draw on this page is an unbiased uniform pick, rejection-sampled from your browser's cryptographic random source — the closest thing software has to the audited machines lottery operators use. It deliberately does not use the Lucky Dip generator's own three-stage shuffle: our generator adds a stylistic low-number tilt for the feel of a hand-picked set, which we're open about in how Lucky Dip works. A fairness demonstration has to be fair, so here you get the plain, boring, perfectly level truth.

What it means for your numbers

In a fair draw every combination — including 1, 2, 3, 4, 5 — has exactly the same chance, every time, regardless of history. So pick numbers you enjoy. The only edge that exists is a social one: unpopular combinations (high numbers, no birthdays) don't improve your odds of winning, but they reduce the risk of sharing a pari-mutuel jackpot, because fewer people pick them. We look at the evidence for that, and at what people's "lucky" numbers actually are, in do lucky numbers work?

Convinced the machine doesn't care?

Then let the generator pick you a fresh set — for the fun of it, not the edge.
