💡 New for 2026: every £2 Lotto line is automatically entered into two separate draws each night — Round 1 and Round 2 — for the same price. You still pick just one set of 6 numbers; the bonus ball is drawn by the machine on the night, so it's never one you choose.
Why this generator

Fair by maths, private by design

Many online pickers lean on Math.random(), which isn't built to be unpredictable. Ours uses your device's cryptographically-secure randomness — the same class trusted for encryption keys — and we use rejection sampling so no number is quietly favoured over another. Your picks are made on your device and never transmitted anywhere.

Worth saying plainly: a generator can't predict a draw or improve your odds. Every UK Lotto combination always has exactly the same chance — 1 in 45,057,474 per line. What this gives you is a clean, unbiased, genuinely random line, free of the human habit of clustering around birthdays and patterns (which only matters for how a jackpot would be split, never for whether you win).

FAQ

Questions, answered

How does the UK Lotto generator work?
It picks 6 unique numbers from 1 to 59 using your device's cryptographically-secure random generator (crypto.getRandomValues) with rejection sampling, so every number is equally likely. Generate multiple lines and copy each with one tap. You don't pick the bonus ball — that's drawn by the machine on the night.
What is the UK Lotto format and price?
UK Lotto (the National Lottery's flagship game, run by Allwyn since 2024) is 6 numbers from 1–59 at £2 per line. From June 2026 every line is automatically entered into two separate rounds each draw night for the same price. Draws are Wednesday & Saturday at about 8pm UK time, sales close at 7:30pm. Jackpot odds are 1 in 45,057,474 per line.
What does the two-round format change?
Your single line of 6 numbers is now entered into two independent draws each night (Round 1 and Round 2) for the same £2. That roughly doubles your chance of winning something on a given night — the per-line jackpot odds are still 1 in 45,057,474, but across both rounds it's about 1 in 22.5 million per draw night.
Can a generator improve my chances of winning?
No. UK Lotto is a game of pure chance and every combination always has exactly the same probability. A generator simply gives you a fair, unbiased random line — handy mainly because it avoids the birthday-and-pattern clustering that makes a shared jackpot more likely to be split.
Are my generated numbers private?
Yes. The generator runs entirely in your browser. Your numbers are never sent to a server and no sign-up is required.
