Generate numbers, look up draws, study the record.

The honest bit

No generator, pattern or statistic can improve your chance of winning. Each draw is independent: a number that came up last week is exactly as likely as one that hasn't appeared for two years.

What our statistics can tell you is what has already happened, and which combinations lots of other people play — so if you do win, you're less likely to share it.

What we do have is the record. We hold the published results for fifteen games across seven countries and we say, on every page, exactly where each figure comes from and how far back our archive goes. Where it is too short to support a statistic, we say that instead of showing one.

The most useful thing anyone can tell you about picking numbers is not which to choose. It is that thousands of other players pick birthdays, so a winning line made of numbers above 31 is shared with fewer people. That changes what you would win, never whether you win — worked through here, including what our own archive can and cannot show about it.

The workings

Every figure on this site is calculated rather than quoted, and the guides go through the arithmetic instead of asserting it.

• How lottery odds are calculated — where a figure like 1 in 45,057,474 comes from, and why quoted odds for bonus-ball games are often wrong.
• How many lines should you play? — a second line does double your chance, and the doubled figure is still roughly zero.
• Consecutive numbers and other patterns — the shape people avoid most turns up in about half of all draws.
• Why hot and cold numbers do not work — the gap between the most and least drawn number is real, and exactly what chance produces.
• Does the draw machine make a difference? — the UK publishes which drum drew every result, so we tested them against each other.
• All eight guides.

The archive is open

Every draw we hold is published as JSON and CSV under CC BY 4.0, with a documented schema and a named source per game. Use it for anything; the only condition is attribution. Take the data, or read how the generator works first.
